Standards

This practice covers a procedure for estimating the quality of extruded poly (vinyl chloride) (PVC) plastic pipes by observing the reaction of pipe specimens after exposure to heat. This standard does not purport to address all of the safety problems, 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 test method covers the determination of the adequacy of fusion of extruded rigid poly (vinyl chloride) (PVC) pipe and molded fittings as indicated by reaction to immersion in anhydrous acetone.

This test method covers the determination of diameter, wall thickness, and length dimensions of thermoplastic pipe. Included are procedures for measurement of the inside diameter of pipe intended to be joined by internal fittings, measurement of the average outside diameter for roundtable pipe where out-of-roundness is not of primary concern, out-of-roundness measurement and measurement of the average outside diameter of non-roundtable pipe, and for determining length and straightness.

This test method covers the determination of the impact resistance of thermoplastic pipe and fittings under specified conditions of impact by means of a tup (falling weight) . Three interchangeable striking noses are used on the tup, differing in geometrical configuration. Two specimen holders are described.

The purpose of these abbreviations is to provide uniform contractions of terms relating to plastics. Abbreviated terminology has evolved through widespread common usage. This compilation of abbreviated nomenclature has been prepared to avoid the occurrence of ore than one abbreviation for a given plastics term, and double meanings for particular abbreviations.

This specification covers poly (vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see Appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.

The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases, some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing.

This International Standard gives specifications for the angular coordinate system to be used in the design of scales, reticles or other display means incorporated in instruments for determining optical data on human eyes or corrective lenses for human eyes.

 This standard establishes the basic principles for carrying out vibration measurement and processing data, with regard to evaluating vibration effects on buildings. The evaluations of the effects of building vibration are primarily directed at structural response, and include appropriate analytical methods where the frequency, duration and amplitude can be defined. It only deals with the measurement of structural vibration and excludes the measurement of   airborne sound pressure and other pressure fluctuations. 

This standard provides general guidance on methods of carrying out penetrant inspection on materials and components both during manufacture and in service. It does not deal with acceptance or rejection. Penetrant inspection is used to locate discontinuities, such as laps, folds, cracks, porosity and fissures, which are open to the surface of a material or component. Penetrant techniques can be used on materials irrespective of their physical properties, provided that the surface is normally non-absorbent and compatible with the penetrant process.
