Many important properties of crosslinked ethylene plastics vary with the gel content. Hence, determination of the gel content provides a means of both controlling the process and rating the quality of finished products.Extraction tests permit verification of the desired gel content of any given crosslinked ethylene plastic and they also permit comparison between different crosslinked ethylene plastics, including those containing fillers, provided that, for the latter, the following conditions are met: The filler is not soluble in xylene or toluene at the extraction temperature and the amount of filler present in the compound is known or can be determined.Sufficient crosslinking has been achieved to prevent migration of filler during the extraction. Usually it has been found that, at extraction levels up to 50 %, the extraction solvent remains clear and free of filler.Since some oxidative degradation of the material can occur at the extraction temperatures used in this procedure, despite the use of a closed cell which allows for minimal introduction of oxygen, a suitable antioxidant is added to the solvent to inhibit such degradation.Before proceeding with this method, reference should be made to 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 apply1.1 The gel content of crosslinked ethylene plastics is determined by solvent extraction with xylene or toluene. This test method is applicable to ethylene plastics of all densities, including those containing fillers; provided the fillers are insoluble in the extraction solvent(s).1.2 This test method uses pressurized liquid extraction (PLE) to increase the speed and reduce the amount of solvent required for solvent extraction. The results of this method are similar to Test Method D2765.1.3 Extraction tests shall be performed on samples of any shape (see 7.2). Specimens shall be selected from those portions of the article most susceptible to insufficient crosslinking or selected from portions representative of the entire article. This test method has been developed for production and quality control of crosslinked polyethylene pipe but may be applicable to other products such as multilayer materials and fibers.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.5 This method makes use of minimal reagents and allows for solvent recovery and re-use. Due to the use of minimal reagents, health and safety concerns are minimized in comparison to other methods.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 and health practices and determine the applicability of regulatory limitations prior to use.Specific precautionary statements are given in Section 10.Note 1—There is no known ISO equivalent to this test method. This test method is similar to Test Method D2765.

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.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.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.

1.1 This specification covers flexible sheet made from ketone ethylene ester (KEE) as the primary polymer intended for use in single-ply roofing membrane exposed to the weather. The sheet shall be reinforced with fabric.1.2 In-place roof system design criteria, such as fire resistance, field-seaming strength, material compatibility, uplift resistance, in-situ shrinkage, among others, are factors that must be considered but are beyond the scope of this specification.1.3 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 nonconformance with the standard.1.4 The following precautionary caveat pertains to the test methods portion only, Section 8, of this specification: 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.
