Standard Classification System and Basis for Specification for Specifying Plastic Films

SIGNIFICANCE AND USE
4.1 The purpose of this classification system is to provide a method of adequately identifying plastic films using a system that applies universally for plastic films. It further provides a means for specifying these films by the use of a simple line call-out designation.  
4.2 This classification system was developed to permit the addition of additional film products and property values.  
4.3 It is intended that the classification of plastic sheeting, >0.25 mm [0.010 in.] thickness, multi-layer structures, blends, and other variants will be addressed in related standards.
SCOPE
1.1 This standard provides a classification system for tabulating the properties of unfilled, single-layer plastic films.
Note 1: The classification system serves many of the needs of industries using plastic films. The standard is subject to revision as the need requires; therefore, the latest revision should always be used.
Note 2: Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.25 mm [0.010 in.].  
1.2 The classification system and subsequent line call-out (specification) is intended to be a means of identifying plastic films used for applications including industrial, packaging, construction, and agriculture. It is not intended for the selection of materials to be used in films. This selection should be made by those having expertise in the plastics field after careful consideration of the end-use requirements, the environment to which the films will be exposed, the fabrication process to be employed, the inherent properties of the material not covered in this document, and the economic factors.  
1.3 This classification system is based on the premise that plastic films can be arranged into broad generic families based on materials with similar composition using basic film properties. A system is thus established which, together with values describing additional requirements, permits as complete a description as desired of the selected film.  
1.4 In all cases where the provisions of this classification system would conflict with the referenced ASTM specification for a particular film product, the latter shall take precedence.
Note 3: It is strongly recommended that this classification system be used for all new applications and specifications and that the specification of films using existing standards be expeditiously withdrawn or converted to this classification system.  
1.5 This classification system applies to commercial products and, as such, there is no control over the manufacturing parameters employed in producing the film. It shall be the responsibility of those developing the specification documents utilizing this classification system to identify the critical parameters and values to be used for the cell classifications and suffix requirements.  
1.6 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
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 4: There is no known ISO equivalent to this standard.  
1.8 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 D6902-04(2023)(Test Method)
Standard Test Method for Laboratory Measurement of Formaldehyde Evolved During the Curing of Melamine-Formaldehyde-Based Coatings

SIGNIFICANCE AND USE
5.1 This test method measures the amount of formaldehyde that is evolved from a coating containing melamine-formaldehyde resin(s) during cure at elevated temperature. Cure formaldehyde results from a side-reaction during cross-linking of functionalized polymers with melamine-formaldehyde resins. Cure formaldehyde is evolved in the final bake or cure oven, when the coating temperature is high enough to initiate cross-linking. Formaldehyde can be released from a coating during application, solvent flash-off and cure. Free formaldehyde is primarily evolved during coating application and solvent flash-off. Test Method D1979 measures “free formaldehyde” in amino resins and Test Method D6191 measures formaldehyde evolved from coatings at ambient temperature. This method measures only the formaldehyde released during heat cure, which is primarily “cure formaldehyde.”  
5.2 This test method is not intended to duplicate the evolved formaldehyde from an industrial process, but serves as a reproducible comparative laboratory evaluation.  
5.3 This test method has not been evaluated with catalyzed coating systems that cure at or below 40 °C, such as those used by the wood-finishing industry, and would likely require special adaptation for this application.
SCOPE
1.1 This test method is for the determination of formaldehyde evolved from melamine-formaldehyde-based coatings during the cure step. The results may be used to determine the “cure formaldehyde” evolved from a sample under controlled laboratory conditions.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This test method is capable of measuring from 500 μg/g to 22 000 μg formaldehyde/g dry coating under the test conditions specified (3 000 ml/min total flow, 50 ml/min DNPH tube flow). The ratio of total flow to DNPH tube flow could be adjusted to extend the range of the method.  
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.  
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 Cure Behavior of Thermosetting Resins by Dynamic Mechanical Procedures using an Encapsulated Specimen Rheometer

SIGNIFICANCE AND USE
5.1 This method provides a simple means of characterizing the cure behavior of a thermosetting resin specimen that is a representation of a composite part. The diameter of the specimen is approximately 38 mm and the thickness ranges from 2.6 mm to 3.2 mm. This corresponds to a sample volume of approximately 3 cm3 to 4 cm3. The data may be used for quality control, research and development, and verifying the cure within processing equipment including autoclaves.  
5.2 Dynamic mechanical testing provides a sensitive method for determining cure characteristics by measuring the elastic and loss moduli as a function of temperature or time, or both. Plots of cure behavior and tan delta of a material provide graphical representation indicative of cure behavior under a specified time-temperature profile. The presence of fibers within the resin may change the dynamic properties measured within a material. However, it is still possible to compare different resins with the same fiber structure and obtain the relative difference due to the resin cure properties.  
5.3 This method can be used to assess the following:  
5.3.1 Cure behavior, as well as changes as a function of temperature or time, or both,  
5.3.2 Processing behavior, as well as changes as a function of temperature or time, or both,  
5.3.3 The effects of processing treatments,  
5.3.4 Relative resin behavioral properties, including cure behavior, damping and impact resistance,  
5.3.5 The effects of reinforcement on cure; the reinforcement can be a fiber or a filler,  
5.3.6 The effects of materials used to bond the resin and reinforcement,  
5.3.7 The effect of formulation additives that might affect processability or performance.  
5.4 This provides a method to assess the cure properties of a thermosetting resin containing woven fiber or other reinforcing materials.  
5.5 This method is valid for a wide range of oscillation frequencies typically from 0.002 Hz to 50 Hz.
Note 1: It is recommended tha...
SCOPE
1.1 This method covers the use of dynamic mechanical instrumentation for determination and reporting of the thermal advancement of cure behavior of thermosetting resin on an inert filler or fiber in a laboratory. It may also be used for determining the cure properties of resins without fillers or fibers. These encapsulated specimens are deformed in torsional shear using dynamic mechanical methods.  
1.2 This method is intended to provide means for determining the cure behavior of thermosetting resins on fibers over a range of temperatures from room temperature to 250 °C by forced-constant amplitude techniques (in accordance with Practice D4065). Plots of complex modulus, complex viscosity, and damping ratio or tan delta as a function of time or temperature, or both, quantify the thermal advancement or cure characteristics of a resin or a resin on filler or fiber.  
1.3 Test data obtained by this method is relevant and appropriate for optimizing cure cycles.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4.1 Exception—The Fahrenheit temperature measurement in 10.1 is provided for information only and is not considered 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 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 Practice for Separation and Identification of Poly(Vinyl Chloride) (PVC) Contamination in Poly(Ethylene Terephthalate) (PET) Flake

SIGNIFICANCE AND USE
5.1 Presence of even low concentrations of PVC in recycled PET flakes results in equipment corrosion problems during processing. The PVC contamination level shall dictate the market for use of the recycled polymer in secondary products. Procedures presented in this practice are used to identify the PVC contamination in recycled PET flakes.
Note 4: These procedures may also be used to estimate the concentration of PVC contamination.
SCOPE
1.1 This practice covers four procedures for separation and qualitative identification of poly(vinyl chloride) (PVC) contamination in poly(ethylene terephthalate) (PET) flakes.
Note 1: Although not presented as a quantitative method, procedures presented in this practice may be used to provide quantitative results at the discretion of the user. The user assumes the responsibility to verify the reproducibility of quantitative results. Data from an independent source suggest a PVC detection level of 200 ppm (w/w) based on an original sample weight of 454 g.  
1.2 Procedure A is based on different fluorescence of PVC and PET when these polymers are exposed to ultraviolet (UV) light.  
1.3 Procedure B is an oven test based upon the charring of PVC when it is heated in air at 235°C.  
1.4 Procedures C and D are dye tests based on differential staining of PVC and PET.  
Note 2: Other polymers (for example, PETG) also absorb the stain or brightener. Such interferences will result in false positive identification of PVC as the contaminant.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazards see Section 8.  
Note 3: There is no known ISO equivalent to this standard.

Standard Test Method for Acid Number of Styrene-Maleic Anhydride Resins

SIGNIFICANCE AND USE
4.1 This test method is used to determine the property of styrene-maleic anhydride resins functionality. Acid functionality determines the utility of resin as well as being a significant quality control test.  
4.2 Because some of the anhydride functionality has been hydrolyzed in the manufacturing process, direct titration with base will produce erroneous data on the total acid content of the fully hydrolyzed resin in use. This test method charges excess alkali to hydrolize the anhydride functionality and neutralize the resulting acid. The remaining unreacted alkali is then back titrated with a standardized acid solution and the acid content is determined by difference.
SCOPE
1.1 This test method covers the measurement of the free acidity present in styrene-maleic anhydride resins.  
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 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.  
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.
