Standards

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 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.

This standard specifies the quality requirements of tomatoes of varieties (cultivars) grown from Lycopersicum esculentum Mill., which are to be supplied fresh to the consumer after reparation and packaging. The standard does not apply to tomatoes for industrial processing. Tomatoes covered under this standard may be classified into four commercial types: a) “round”; b) “ribbed”; c) “oblong” or “elongated”; and d) “cherry” tomatoes (including “cocktail” tomatoes).

This specification covers chlorinated poly(vinyl chloride) (CPVC) pipes made in standard thermoplastic pipe dimension ratios and pressure rated for water. (See Appendix). Included are criteria for classifying CPVC plastic pipe materials and CPVC plastic pipe, and requirements and test methods for materials, workmanship, dimension, sustained pressure, burst pressure, flattening, and extursion quality. Methods of marking are also given.

This standard establishes requirements for grades of paddy, cargo rice, milled rice; cargo parboiled rice and milled parboiled rice.  It also specifies the general conditions for sampling and the methodologies for assessing the various factors used in the determination of the quality of rice.

This standard specifies the requirements and methods of test for urea, fertiliser grade.

The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

This standard specifies requirements for circular-cross-section seamless polypropylene (PP) pipes made from homopolymer polypropylene (PP-H), block copolymer polypropylene (PP-R) or random copolymer polypropylene with modified crystalline structure and elevated temperature resistance (PP-RCT).
