Standard Specification for Dense Thermoplastic Elastomers Used for Compression Seals, Gaskets, Setting Blocks, Spacers and Accessories

ABSTRACT
This specification covers the properties of products made from dense thermoplastic elastomers used for compression seals, gaskets, setting blocks, spacers, and accessories for building construction sealing and glazing applications. The products are categorized into types according to resistance to tearing and compression set, grades based on durometer hardness, classes by flame propagation requirements, and into surfaces according to the surface characteristics. All products should be a performed extrusion manufactured from a thermoplastic vulcanizate and should conform to the specified requirements for tensile strength, elongation at break, hardness, ozone resistance, compression set, heat aging, tear resistance, brittleness temperature, and water absorption.
SCOPE
1.1 This specification describes products composed of dense thermoplastic elastomers that are fabricated into gaskets and accessories (such as compression seals, setting blocks, spacers, and shims) for use in sealing and glazing applications in building construction. These products are used to seal or serve as components of compression sealing systems between mechanically restrained surfaces in building construction.
1.2 The values stated in metric (SI) units are to be regarded as the standard. The inch-pound values given in parentheses are provided for information purposes only.
1.3 Test Method C 1166, as referenced in this specification, should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment that takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.
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 and health practices and determine the applicability of regulatory requirements prior to use.

Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer

SIGNIFICANCE AND USE
5.1 This test method is particularly useful for quality control tests on thermoplastics.  
5.2 The data produced by this test method serves to indicate the uniformity of the flow rate of the polymer as made by an individual process. It is not to be used as an indication of uniformity of other properties without valid correlation with data from other tests.  
5.3 The flow rate obtained with the extrusion plastometer is not a fundamental polymer property. It is an empirically defined parameter critically influenced by the physical properties and molecular structure of the polymer and the conditions of measurement. The rheological characteristics of polymer melts depend on a number of variables. It is possible that the values of these variables occurring in this test will differ substantially from those in large-scale processes, which would result in data that does not correlate directly with processing behavior.  
5.4 Measure the flow rate of a material using any of the conditions listed for the material in X4.1. For many materials, there are specifications that require 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 in Classification D4000 lists the ASTM materials standards that currently exist. An alternative test method for poly (vinyl chloride) (PVC) compounds is found in Test Method D3364.  
5.5 Additional characterization of a material can be obtained if more than one condition is used. In the case that two or more conditions are employed, a Flow Rate Ratio (FRR) is obtained by dividing the flow rate at one condition by the flow rate at another condition. Procedure D provides one method to measure more than one condition in a single charge.  
5.6 Frequently, variations in test technique, apparatus geometry, or test conditions, which defy all but the most careful scrutiny, exist...
SCOPE
1.1 This test method covers the determination of the rate of extrusion of molten thermoplastic resins using an extrusion plastometer.  
1.2 The values stated in SI units are to be regarded as 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.
Note 1: This standard and ISO 1133 address the same subject matter, but differ in technical content.  
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 Environmental Stress-Crack Resistance of Blow-Molded Polyethylene Containers

SIGNIFICANCE AND USE
5.1 When properly used, these procedures serve to isolate such factors as material, blow-molding conditions, post-treatment, and so forth, on the stress-crack resistance of the container.  
5.2 Environmental stress cracking of blow-molded containers is governed by many factors. Since variance of any of these factors can change the environmental stress-crack resistance of the container, the test results are representative only of a given test performed under defined conditions in the laboratory. The reproducibility of results between laboratories on containers made on more than one machine from more than one mold has not been established.  
5.3 Results can be used for estimating the shelf life of blow-molded containers in terms of their resistance to environmental stress cracking provided this is done against a rigorous background of practical field experience and reproducible test data.
SCOPE
1.1 Under certain conditions of stress, and in the presence of environments such as soaps, wetting agents, oils, or detergents, blow-molded polyethylene containers exhibit mechanical failure by cracking at stresses appreciably below those that would cause cracking in the absence of these environments.  
1.2 This test method measures the environmental stress crack resistance of blow-molded containers, which is the summation of the influence of container design, resin, blow-molding conditions, post treatment, or other factors that can affect this property. Three procedures are provided as follows:  
1.2.1 Procedure A, Stress-Crack Resistance of Containers to Potential Stress-cracking Liquids—This procedure is particularly useful for determining the effect of container design on stress-crack resistance or the stress-crack resistance of a proposed container that contains a liquid product.  
1.2.2 Procedure B, Stress-Crack Resistance of a Specific Container to Polyoxyethylated Nonylphenol (CAS 68412-54-4), a Stress-Cracking Agent—The conditions of test described in this procedure are designed for testing containers made from Class 3 polyethylene Specification D4976. Therefore, this procedure is recommended for containers made from Class 3 polyethylene only. This procedure is particularly useful for determining the effect of resin on the stress-crack resistance of the container.  
1.2.3 Procedure C, Controlled Elevated Pressure Stress-Crack Resistance of a Specific Container to Polyoxyethylated Nonylphenol (CAS 68412-54-4), a Stress-Cracking Agent—The internal pressure is controlled at a constant elevated level.
Note 1: There are environmental concerns regarding the disposal of Polyoxyethylated Nonylphenol (Nonylphenoxy poly(ethyleneoxy) ethanol (CAS 68412-54-4), for example, Igepal CO-630). Users are advised to consult their supplier or local environmental office and follow the guidelines provided for the proper disposal of this chemical.  
1.3 These procedures are not designed to test the propensity for environmental stress cracking in the neck of containers, such as when the neck is subjected to a controlled strain by inserting a plug.  
1.4 The values stated in SI units are to be regarded as standard.  
Note 2: There is no known ISO equivalent to this 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. Specific precautionary statements are given in Section 8 and Note 1.  
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.

1.4 This classification system and subsequent line callout (specification) are intended to provide means of calling out poly(ether ketone ketone) materials used in the fabrication of end items or parts.  
1.5 Poly(ether ketone ketone) (PEKK) is a member of the poly (aryl ether ketone) or PAEK polymer family. PEKK has a broad range of repeat unit combinations of Isophthaloyl and Terephthaloyl repeat units. This standard classifies the polymer options.  
1.6 The values stated in SI units, as detailed in IEEE/ASTM S-10, 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.
Note 1: There is no known ISO equivalent to this standard.
Note 2: PEKK is a thermoplastic polymer. Testing conditions can affect the technical results. Specimens prepared by techniques different than prescribed in this specification can have properties that vary from the values specified.  
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.

Standard Practice for Sampling and Testing Frequency for Recycled Materials in Polyethylene (PE) Pipe for Non-Pressure Applications

SIGNIFICANCE AND USE
4.1 The utilization of recycled materials in non-pressure thermoplastic pipe presents a potentially large outlet for this what is typically classified “waste” material. The proper use and qualification of this material is critical in assuring its long-term performance from both a structural and durability standpoint.  
4.2 This practice defines minimum requirements and testing protocols and frequencies for these recycled materials with respect to their utilization in final thermoplastic pipe products. Each specific pipe standard has unique criteria that must be met in addition to the items described in this practice.  
4.3 The purpose of this specification is for characterization of recycled plastics only and does not establish performance guidelines for such materials. Product specifications may be used in conjunction with this specification to establish performance specifications for a defined end-use and specific material type.
SCOPE
1.1 This practice covers requirements and sampling frequency for the use of post-consumer and post-industrial recycled plastic materials in polyethylene (PE) pipe used in storm drainage, storm sewer and sanitary sewer applications.  
1.2 The requirements of this practice provide definitions, requirements and test protocols for recycled plastic materials to be used in the production of polyethylene (PE) pipe for gravity flow applications.  
Note 1: Non-pressure applications pertain principally to any municipal or private facilities for land drainage, storm drainage, storm sewer, culvert and sanitary sewer applications. The products utilizing the criteria under this practice are not intended for any pressure pipe applications, such as water or gas pipelines.  
1.3 Units—The values stated in either inch-pound units or SI 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 independent of the other. Combining values from the two systems may result in non-conformance with 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.  
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 Melt Rheology

SIGNIFICANCE AND USE
5.1 This test method provides a simple means of characterizing the important rheological properties and viscosity of thermoplastic polymers using very small amounts of material (approximately 25 to 50 mm in diameter by 1 to 3 mm in thickness ... approximately 3 to 5 g). Data are generally used for quality control, research and development, and establishment of optimum processing conditions.  
5.2 Dynamic mechanical testing provides a sensitive method for determining molten polymer properties by measuring the elastic and loss moduli as a function of frequency, strain, temperature, or time. Plots of viscosity, storage, and loss moduli, and tan delta as a function of the aforementioned process parameters provide graphical representation indicative of molecular weight, molecular weight distribution, effects of chain branching, and melt-processability for 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 Values obtained in this test method can be used to assess the following:  
5.3.1 Complex viscosity of the polymer melt as a function of dynamic oscillation,  
5.3.2 Processing viscosity, minimum as well as changes in viscosity as a function of experimental parameters,  
5.3.3 Effects of processing treatment,  
5.3.4 Relative polymer behavioral properties, including viscosity and damping, and  
5.3.5 Effects of formulation additives that might affect processability or performance.  
5.4 Before proceeding with this test method, refer to the specification for 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 mentioned in the test method. If there are no r...
SCOPE
1.1 This test method outlines the use of dynamic mechanical instrumentation in determining and reporting the rheological properties of thermoplastic resins and other types of molten polymers. The method is useful for determining the complex viscosity and other significant viscoelastic characteristics of such materials as a function of frequency, strain amplitude, temperature, and time. It is known that fillers and other additives influence rheological properties.  
1.2 It incorporates a laboratory test method for determining the relevant rheological properties of a polymer melt subjected to various oscillatory deformations on an instrument of the type commonly referred to as a mechanical or dynamic spectrometer.  
1.3 This test method is intended to provide a means of determining the rheological properties of molten polymers, such as thermoplastics and thermoplastic elastomers over a range of temperatures by nonresonant, forced-vibration techniques. Plots of modulus, viscosity, and tan delta as a function of dynamic oscillation (frequency), strain amplitude, temperature, and time are indicative of the viscoelastic properties of a molten polymer.  
1.4 This test method is valid for a wide range of frequencies, typically from 0.01 Hz to 100 Hz.  
1.5 This test method is intended for homogenous and heterogeneous molten polymeric systems and composite formulations containing chemical additives, including fillers, reinforcements, stabilizers, plasticizers, flame retardants, impact modifiers, processing aids, and other important chemical additives often incorporated into a polymeric system for specific functional properties, and which could affect the processability and functional performance. These polymeric material systems have molten viscosities typically less than 106 Pa·s (107 poise).  
1.6 Test data obtained by this test method are relevant and appropriate for use in engineering design.

ASTM D2463-23(Test Method)
Standard Test Method for Drop Impact Resistance of Blow-Molded Thermoplastic Containers

SIGNIFICANCE AND USE
5.1 These procedures provide a means to assess the drop impact resistance of the group or lot of blown containers from which the test specimens were selected.  
5.2 It is acceptable to use these procedures for routine inspection purposes.  
5.3 These procedures will evaluate the combined effect of construction, materials, and processing conditions on the impact resistance of the blown containers.  
5.4 Before proceeding with this test method, reference the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply.
SCOPE
1.1 This test method provides a means to assess the drop impact resistance of water-filled, blow-molded thermoplastic containers, which is a summation of the effects of material, manufacturing conditions, container design, and perhaps other factors.  
1.2 Two procedures are provided as follows:  
1.2.1 Procedure A, Static Drop Height Method—This procedure is particularly useful for quality control since it is quick.  
1.2.2 Procedure B, Bruceton Staircase Method—This procedure is used to determine the mean failure height and the standard deviation of the distribution.  
1.3 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only.  
Note 1: There is no known ISO equivalent to 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.  
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.
