1.1 This specification covers coextruded poly(vinyl chloride) (PVC) plastic drain, waste and vent pipe made to Schedule 40 iron pipe sizes (IPS) and produced by the coextrusion process with concentric inner and outer solid PVC layers and the core consisting of closed-cell cellular PVC. Plastic which does not meet the material requirements specified in Section 5 is excluded from single layer and all coextruded layers.1.2 Fittings meeting the requirements of Specification D2665 and D3311 are suitable for use with pipe meeting the requirements of this specification.1.3 Poly(vinyl chloride) plastic which does not meet the definitions of virgin PVC plastic as given in 5.1 is excluded, as performance of plastic other than those defined as virgin was not determined. PVC rework plastic which meets the requirements of rework plastic as given in 5.2 is acceptable.1.4 Reprocessed plastic or recycled plastic as defined in Terminology D883 is excluded.1.5 Recommendations for storage, joining and installation are provided in Appendix X1, Appendix X2, and Appendix X3 respectively.1.6 The text of this specification references notes, footnotes and appendices which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.8 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.1.9 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 test method covers the measurement of MOSFET (Note 1) drain leakage current.Note 1—MOS is an acronym for metal-oxide semiconductor; FET is an acronym for field-effect transistor.1.2 This test method is applicable to all enhancement-mode and depletion-mode MOSFETs. This test method specifies positive voltage and current, conventions specifically applicable to n-channel MOSFETs. The substitution of negative voltage and negative current makes the method directly applicable to p-channel MOSFETs.1.3 This d-c test method is applicable for the range of drain voltages greater than 0 V but less than the drain breakdown voltage.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 limitations prior to use.

This specification covers the performance of shielded transition couplings using flexible PVC gaskets to join dissimilar DWV pipe and fittings above and below ground. The gaskets shall be permitted to be spliced or molded. The elastomeric gasket shall be free from imperfections and porosity that affects its use and serviceability. Clamps assembly screws or bolts shall not have screw-driver slots. Each coupling shall undergo deflection test, shear test, and unrestrained hydrostatic joint test.1.1 This specification describes the properties of devices or assemblies suitable for use as mechanical couplings using thermoplastic elastomeric (TPE) gaskets, hereinafter referred to as couplings, for joining drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems for above and below ground use.1.2 The pipe to be joined shall be of similar or dissimilar materials or size, or both.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 The ASTM standards referenced herein shall be considered mandatory.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.
