This International Standard specifies a colorimetric comparison method for the determination of the amount of ammonia and ammonium compounds in phenol-formaldehyde mouldings. NOTE This International Standard does not provide an absolute measure of the amount of ammonia present. The amount of ammonia in a moulded article is of importance when corrosion of metal inserts or contamination of…

1. Scope 1.1 This Standard provides requirements for thermoplastic pressure piping. It includes definitions, abbreviations, reference publications, general requirements for raw materials, general requirements for manufactured pipe and fittings, the relevant test methods, and marking requirements. Note: The terms "pipe", "piping", "tube", and "tubing…

1. Scope 1.1 This Standard provides requirements for rigid polyvinyl chloride (PVC) injection-moulded fittings intended for use in pressure applications such as water mains, water service piping, process piping, and fire lines. Fittings covered by this Standard are suitable for use with PVC pipes having outside diameter (OD) dimensions of cast iron pipe. Only one pressure rating, 1620…

1. Scope 1.1 This Standard provides requirements for rigid polyvinyl chloride (PVC) pipe and fittings intended for use in pressure applications such as water mains, water service piping, and process piping. Included are moulded, solvent-cemented, gasketed, or threaded fittings, and fittings that have been fabricated for use with any jointing method. Note: If PVC pipe and fittings are to…

1. Scope 1.1 This Standard provides requirements for polyethylene pipe, tubing, and fittings for use in gas mains and services, including gathering, transmission, and distribution applications, that carry fuel gases containing not more than 1% aromatic hydrocarbons. 1.2 This Standard also applies to all types of fittings and connections used in a plastic gas pipe system, including…

1. Scope 1.1 This Standard covers performance testing of socket- and saddle-type polyethylene electrofusion fittings that are used to join polyethylene pipe where the heat source is an integral part of the fitting. Note: Fittings covered by this Standard are connected to an electrical power source during the fusion process. Power sources, cables, and electrical connections are covered…

1. Scope 1.1 This Standard provides requirements for crosslinked polyethylene pressure tubing systems. Components are made in one standard dimension ratio (SDR 9) and are intended for use in potable water distribution systems at a maximum working temperature of 82°C and 690 kPa (100 psi). Note: The pressure rating for water at 23°C and 93°C is given in Appendix A. 1.2 The components…

1. Scope 1.1 This Standard provides requirements for polybutylene (PB) pipe, tubing, and fittings. Nominal pipe sizes (NPS) covered are from NPS-1/4 through NPS-2. Fittings covered include insert-type fittings, socket fusion fittings, plastic-to-metal transition fittings, and compression-type fittings. These pipes, tubing, and fittings are intended for use in pressure applications…

1. Scope 1.1 This Standard provides requirements for macrocomposite pipe consisting of a welded aluminum tube laminated by a melt adhesive to layers of polyethylene inside and outside the aluminum tube. The Standard also provides requirements for fittings (connectors) for use with this composite pipe. The pipes considered in this Standard are for use in potable water supply systems and…
