Standard Classification for Low Molecular Weight PTFE and FEP Micronized Powders

Standard Classification for Low Molecular Weight PTFE and FEP Micronized Powders

ABSTRACT
This classification system provides a method of adequately identifying PTFE micropowders using a system consistent with that also of another specific classification. These powders are sometimes known as lubricant powders which usually have a much smaller particle size than those used for molding or extrusion. The test methods and properties included are those required to identify and specify the various types of fluoropolymer micropowders. This classification covers two groups of fluoropolymer micropowders. Fluoropolymer micropowders are classified into groups according to their base fluoropolymer. These groups are further subdivided into classes and grades. Different tests shall be performed in order to determine the following properties of the micropowders: melting characteristics, melt flow rate, specific gravity, water content, particle size, surface area, and bulk density.
SCOPE
1.1 This classification system provides a method of adequately identifying low molecular weight polytetrafluoroethylene (PTFE) and fluorinated ethylene propylene (FEP) micronized powders using a system consistent with that of Classification System D4000. It further provides a means for specifying these materials by the use of a simple line callout designation. This classification covers fluoropolymer micronized powders that are used as lubricants and as additives to other materials in order to improve lubricity or to control other characteristics of the base material.  
1.2 These powders are sometimes known as lubricant powders. The powders usually have a much smaller particle size than those used for molding or extrusion, and they generally are not processed alone. The test methods and properties included are those required to identify and specify the various types of fluoropolymer micronized powders. Recycled fluoropolymer materials meeting the detailed requirements of this classification are included (see Guide D7209).  
1.3 These fluoropolymer micronized powders and the materials designated as filler powders (F) in ISO 12086-1 and ISO 12086-2 are equivalent.2  
1.4 The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 7.1.2.

ABSTRACT
This classification system provides a method of adequately identifying PTFE micropowders using a system consistent with that also of another specific classification. These powders are sometimes known as lubricant powders which usually have a much smaller particle size than those used for molding or extrusion. The test methods and properties included are those required to identify and specify the various types of fluoropolymer micropowders. This classification covers two groups of fluoropolymer micropowders. Fluoropolymer micropowders are classified into groups according to their base fluoropolymer. These groups are further subdivided into classes and grades. Different tests shall be performed in order to determine the following properties of the micropowders: melting characteristics, melt flow rate, specific gravity, water content, particle size, surface area, and bulk density.
SCOPE
1.1 This classification system provides a method of adequately identifying low molecular weight polytetrafluoroethylene (PTFE) and fluorinated ethylene propylene (FEP) micronized powders using a system consistent with that of Classification System D4000. It further provides a means for specifying these materials by the use of a simple line callout designation. This classification covers fluoropolymer micronized powders that are used as lubricants and as additives to other materials in order to improve lubricity or to control other characteristics of the base material.  
1.2 These powders are sometimes known as lubricant powders. The powders usually have a much smaller particle size than those used for molding or extrusion, and they generally are not processed alone. The test methods and properties included are those required to identify and specify the various types of fluoropolymer micronized powders. Recycled fluoropolymer materials meeting the detailed requirements of this classification are included (see Guide D7209).  
1.3 These fluoropolymer micronized powders and the materials designated as filler powders (F) in ISO 12086-1 and ISO 12086-2 are equivalent.2

ASTM D1203-23(Test Method)
Standard Test Methods for Volatile Loss from Plastics Using Activated Carbon Methods

SIGNIFICANCE AND USE
4.1 The test methods are intended to be rapid empirical tests which have been found to be useful in the relative comparison of materials having the same nominal thickness.
Note 2: When the plastic material contains plasticizer, loss from the plastic is assumed to be primarily plasticizer. The effect of moisture is considered to be negligible.  
4.2 Correlation with ultimate application for various plastic materials shall be determined by the user.
SCOPE
1.1 These test methods cover the determination of volatile loss from a plastic material under defined conditions of time and temperature, using activated carbon as the immersion medium.  
1.2 Two test methods are covered as follows:  
1.2.1 Test Method A, Direct Contact with Activated Carbon—In this test method the plastic material is in direct contact with the carbon. This test method is particularly useful in the rapid comparison of a large number of plastic specimens.  
1.2.2 Test Method B, Wire Cage—This test method prescribes the use of a wire cage, which prevents direct contact between the plastic material and the carbon. By eliminating the direct contact, the migration of the volatile components to the surrounding carbon is minimized and loss by volatilization is more specifically measured.  
1.3 The values stated in SI units are to be regarded as the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: This standard and ISO 176 address the same subject matter, but differ in technical content.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D883-23(Terminology)
Standard Terminology Relating to Plastics

SCOPE
1.1 This terminology covers definitions of technical terms used in the plastics industry. Terms that are generally understood or adequately defined in other readily available sources are not included.  
1.2 When a term is used in an ASTM document for which Committee D20 is responsible it is included only when judged, after review, by Subcommittee D20.92 to be a generally usable term.  
1.3 Definitions that are identical to those published by another standards body are identified with the abbreviation of the name of the organization; for example, IUPAC is the International Union of Pure and Applied Chemistry.  
1.4 A definition is a single sentence with additional information included in discussion notes.
Note 1: It is recommended that definitions be reviewed periodically.  
1.4.1 When a new definition is added to this terminology standard, or the wording of a definition is revised, the date of the change shall be appended to the new or revised definition.  
1.5 For literature related to plastics terminology, see Appendix X1.  
1.6 Subsections 1.6.1 – 1.6.5 contain references to specific terminology standards that are relevant to specific plastic products or applications. In case of conflict between a definition contained in Terminology D883 and one contained in another standard, the definition given in Terminology D883 shall prevail.  
1.6.1 For terms related to thermal insulation, the applicable definitions are contained in Terminology C168.  
1.6.2 For terms related to electrical or electronic insulating materials, the applicable definitions are contained in Terminology D1711.  
1.6.3 For terms relating to fire, the applicable definitions are contained in Terminology E176 and ISO 13943. In case of conflict between Terminology E176 and ISO 13943, the definitions given in Terminology E176 shall prevail.  
1.6.4 For terms relating to precision and bias and associated issues, the applicable definitions are contained in Terminology E456.  
1.6.5 For terms related to plastic piping systems, the applicable definitions are contained in Terminology F412.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D3763-23(Test Method)
Standard Test Method for High Speed Puncture Properties of Plastics Using Load and Displacement Sensors

SIGNIFICANCE AND USE
4.1 This test method is designed to provide load versus deformation response of plastics under essentially multi-axial deformation conditions at impact velocities. This test method further provides a measure of the rate sensitivity of the material to impact.  
4.2 Multi-axial impact response, while partly dependent on thickness, does not necessarily have a linear correlation with specimen thickness. Therefore, results must be compared only for specimens of essentially the same thickness, unless specific responses versus thickness formulae have been established for the material.  
4.3 For many materials, there are cases where a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material specification before using this test method. Table 1 of Classification System D4000 lists the ASTM materials standards that currently exist.
SCOPE
1.1 This test method covers the determination of puncture properties of rigid plastics over a range of test velocities.  
1.2 Test data obtained by this test method are relevant and appropriate for use in engineering design.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: This standard and ISO 6603-2 address the same subject matter, but differ in technical content. The technical content and results shall not be compared between the two test methods.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Plastics: Dynamic Mechanical Properties: In Flexure (Three-Point Bending)

SIGNIFICANCE AND USE
5.1 This test method provides a simple means of characterizing the thermomechanical behavior of plastic compositions using very small amounts of material. The data obtained is used for quality control, research and development as well as the establishment of optimum processing conditions.  
5.2 Dynamic mechanical testing provides a sensitive means for determining thermomechanical characteristics by measuring the elastic and loss moduli as a function of frequency, temperature, or time. Plots of moduli and tan delta of a material versus these variables can be used to provide a graphical representation indicative of functional properties, effectiveness of cure (thermosetting resin system), and damping behavior under specified conditions.  
5.2.1 Observed data are specific to experimental conditions. Reporting in full (as described in this test method) the conditions under which the data was obtained is essential to assist users with interpreting the data an reconciling apparent or perceived discrepancies.  
5.3 This test method can be used to assess:  
5.3.1 Modulus as a function of temperature,  
5.3.2 Modulus as a function of frequency,  
5.3.3 The effects of processing treatment,  
5.3.4 Relative resin behavioral properties, including cure and damping.  
5.3.5 The effects of substrate types and orientation (fabrication) on modulus,  
5.3.6 The effects of formulation additives which might affect processability or performance,  
5.3.7 The effects of annealing on modulus and glass transition temperature,  
5.3.8 The effect of aspect ratio on the modulus of fiber reinforcements, and  
5.3.9 The effect of fillers, additives on modulus and glass transition temperature.  
5.4 Before proceeding with this test method, refer to the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials specification shall take precedence over those m...
SCOPE
1.1 This test method outlines the use of dynamic mechanical instrumentation for determining and reporting the visco-elastic properties of thermoplastic and thermosetting resins and composite systems in the form of rectangular bars molded directly or cut from sheets, plates, or molded shapes. The data generated, using three-point bending techniques, is used to identify the thermomechanical properties of a plastic material or compositions using a variety of dynamic mechanical instruments.  
1.2 This test method is intended to provide means for determining the viscoelastic properties of a wide variety of plastics materials using nonresonant, forced-vibration techniques in accordance with Practice D4065. Plots of the elastic (storage) modulus; loss (viscous) modulus; complex modulus and tan delta as a function of frequency, time, or temperature are indicative of significant transitions in the thermomechanical performance of polymeric material systems.  
1.3 This test method is valid for a wide range of frequencies, typically from 0.01 Hz to 100 Hz.  
1.4 Due to possible instrumentation compliance, the data generated are intended to indicate relative and not necessarily absolute property values.  
1.5 Test data obtained by this test method are relevant and appropriate for use in engineering design.  
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

5.2.1 Observed data are specific to experimental conditions. Reporting in full (as described in this test method) the conditions under which the data was obtained is essential to assist users with interpreting the data an reconciling apparent or perceived discrepancies.  
5.3 This test method can be used to assess:  
5.3.1 Modulus as a function of temperature,  
5.3.2 Modulus as a function of frequency,  
5.3.3 The effects of processing treatment, including orientation,  
5.3.4 Relative resin behavioral properties, including cure and damping,  
5.3.5 The effects of substrate types and orientation (fabrication) on elastic modulus,  
5.3.6 The effects of formulation additives which might affect processability or performance,  
5.3.7 The effects of annealing on modulus and glass transition temperature,  
5.3.8 The effect of aspect ratio on the modulus of fiber reinforcements, and  
5.3.9 The effect of fillers, additives on modulus and glass transition temperature.  
5.4 Before proceeding with this test method, make reference to the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials specificati...
SCOPE
1.1 This test method outlines the use of dynamic mechanical instrumentation for gathering and reporting the viscoelastic properties of thermoplastic and thermosetting resins and composite systems in the form of rectangular specimens molded directly or cut from sheets, plates, or molded shapes. The tensile data generated is used to identify the thermomechanical properties of a plastic material or composition using a variety of dynamic mechanical instruments.  
1.2 This test method is intended to provide a means for determining viscoelastic properties of a wide variety of plastic materials using nonresonant forced-vibration techniques, in accordance with Practice D4065. Plots of the elastic (storage) modulus; loss (viscous) modulus; complex modulus and tan delta as a function of frequency, time, or temperature are indicative of significant transitions in the thermomechanical performance of the polymeric material system.  
1.3 This test method is valid for a wide range of frequencies, typically from 0.01 Hz to 100 Hz.  
1.4 Due to possible instrumentation compliance, the data generated are intended to indicate relative and not necessarily absolute property values.  
1.5 Test data obtained by this test method are relevant and appropriate for use in engineering design.  
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: This test method is technically equivalent to ISO 6721, Part 4.

Standard Test Method for Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics (Oxygen Index)

SIGNIFICANCE AND USE
5.1 This test method provides for the measuring of the minimum concentration of oxygen in a flowing mixture of oxygen and nitrogen that will just support flaming combustion of plastics. Correlation with burning characteristics under actual use conditions is not implied.  
5.2 In this test method, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire-test-exposure conditions described in this test method.
SCOPE
1.1 This fire-test-response standard describes a procedure for measuring the minimum concentration of oxygen, expressed as percent volume, that will just support flaming combustion in a flowing mixture of oxygen and nitrogen.  
1.2 This test method provides three testing procedures. Procedure A involves top surface ignition, Procedure B involves propagating ignition, and Procedure C is a short procedure involving the comparison with a specified minimum value of the oxygen index.  
1.3 Test specimens used for this test method are prepared into one of six types of specimens (see Table 1).    
1.4 This test method provides for testing materials that are structurally self-supporting in the form of vertical bars or sheet up to 10.5-mm thick. Such materials are solid, laminated or cellular materials characterized by an apparent density greater than 15 kg/m3.  
1.5 This test method also provides for testing flexible sheet or film materials, while supported vertically.  
1.6 This test method is also suitable, in some cases, for cellular materials having an apparent density of less than 15 kg/m3.
Note 1: Although this test method has been found applicable for testing some other materials, the precision of the test method has not been determined for these materials, or for specimen geometries and test conditions outside those recommended herein.  
1.7 This test method measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statement are given in Section 10.  
1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
Note 2: This test method and ISO 4589-2 are technically equivalent when using the gas measurement and control device described in 6.3.1, with direct oxygen concentration measurement.  
1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Compressive Properties of Rigid Plastics

SIGNIFICANCE AND USE
4.1 Compression tests provide information about the compressive properties of plastics when employed under conditions approximating those under which the tests are made.  
4.2 Compressive properties include modulus of elasticity, yield stress, deformation beyond yield point, and compressive strength (unless the material merely flattens but does not fracture). Materials possessing a low order of ductility may not exhibit a yield point. In the case of a material that fails in compression by a shattering fracture, the compressive strength has a very definite value. In the case of a material that does not fail in compression by a shattering fracture, the compressive strength is an arbitrary one depending upon the degree of distortion that is regarded as indicating complete failure of the material. Many plastic materials will continue to deform in compression until a flat disk is produced, the compressive stress (nominal) rising steadily in the process, without any well-defined fracture occurring. Compressive strength can have no real meaning in such cases.  
4.3 Compression tests provide a standard method of obtaining data for research and development, quality control, acceptance or rejection under specifications, and special purposes. The tests cannot be considered significant for engineering design in applications differing widely from the load-time scale of the standard test. Such applications require additional tests such as impact, creep, and fatigue.  
4.4 Before proceeding with this test method, reference should be made to the ASTM specification for the material being tested. Any test specimen preparation, conditioning, dimensions, and testing parameters covered in the materials specification shall take precedence over those mentioned in this test method. If there is no material specification, then the default conditions apply. Table 1 in Classification D4000 lists the ASTM materials standards that currently exist.
SCOPE
1.1 This test method covers the determination of the mechanical properties of unreinforced and reinforced rigid plastics, including high-modulus composites, when loaded in compression at relatively low uniform rates of straining or loading. Test specimens of standard shape are employed. This procedure is applicable for a composite modulus up to and including 41,370 MPa (6,000,000 psi).  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
Note 1: For compressive properties of resin-matrix composites reinforced with oriented continuous, discontinuous, or cross-ply reinforcements, tests may be made in accordance with Test Method D3410/D3410M or D6641/D6641M.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in 13.1.
Note 2: This standard is equivalent to ISO 604.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determining Ignition Temperature of Plastics

SIGNIFICANCE AND USE
4.1 Tests made under conditions herein prescribed can be of considerable value in comparing the relative ignition characteristics of different materials. Values obtained represent the lowest ambient air temperature that will cause ignition of the material under the conditions of this test. Test values are expected to rank materials according to ignition susceptibility under actual use conditions.  
4.2 This test is not intended to be the sole criterion for fire hazard. In addition to ignition temperatures, fire hazards include other factors such as burning rate or flame spread, intensity of burning, fuel contribution, products of combustion, and others.
SCOPE
1.1 This fire test response test method2 covers a laboratory determination of the flash ignition temperature and spontaneous ignition temperature of plastics using a hot-air furnace.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 Caution—During the course of combustion, gases or vapors, or both, are evolved that have the potential to be hazardous to personnel.  
1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 1.3 and 1.4.
Note 1: This test method and ISO 871-2022 (Option 1) are similar in all technical details.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
