1 Scope 1.1 This Standard covers chlorinated polyvinylchloride (CPVC) pipe, tubing, and fittings in the following sizes and uses: a) standard dimension ratio 11 (SDR 11), and Schedules 40 and 80 pipe in pipe sizes whose dimension ratio does not exceed 11, for use in hot- and cold-water distribution systems at a maximum working pressure of 690 kPa and a maximum working temperature of 82 °C;…

1 Scope 1.1 This Standard covers polyethylene/aluminum/polyethylene (PE-AL-PE) macrocomposite pipe consisting of a welded aluminum tube laminated by a melt adhesive to layers of polyethylene (PE) inside and outside the aluminum tube. The pipes covered in this Standard are pressure rated for 1380 kPa at 23 °C, 1035 kPa at 60 °C, or 690 kPa at 82 °C. Systems are intended for use in potable water…

1 Scope 1.1 This Standard covers crosslinked polyethylene/aluminum/crosslinked polyethylene (PEX-AL-PEX) macrocomposite pipe consisting of a welded aluminum (AL) tube laminated by a melt adhesive to layers of crosslinked polyethylene (PEX) inside and outside the aluminum tube. This Standard also covers fittings (connectors) for use with PEX-AL-PEX pipe. The pipes covered in this Standard are…

1 Scope 1.1 This Standard covers two types of polypropylene (PP) pipe and fittings – polypropylene random copolymer (PP-R) and polypropylene random copolymer with modified crystallinity and temperature resistance (PP-RCT) intended for use in pressure applications such as hot and cold potable water distribution systems, process piping, reclaimed/recycled water systems, water service, hydronic…

1 Scope 1.1 This Standard covers polyamide (PA) pipe, tubing, and fittings for use in gas mains and services, including the gathering, transmission, and distribution of gases that can contain aromatic hydrocarbons. 1.2 This Standard covers all types of fittings and connections used in PA piping systems for gas services, including plastic-to-metal transition fittings, plastic component…

1 Scope 1.1 This Standard specifies requirements for polyethylene of raised temperature (PE-RT) tubing systems that comprise tubing and fittings. Tubing covered by this Standard is made in Standard Dimensional Ratio 9 (SDR 9). Systems are pressure rated at two temperatures: 1105 kPa at 23 °C and 690 kPa at 82 °C. Systems are intended for use in potable water distribution systems or other…

1 Scope 1.1 This Standard covers crosslinked polyethylene (PEX) pipe and fittings for use in gas mains and services, including gas gathering, gas transmission, and distribution of fuel gases. 1.2 This Standard covers PEX pipes in metric nominal sizes DN 16 to DN 1000 or nominal pipe sizes NPS-3 to NPS-54 that are a) pressure-rated using the hydrostatic design basis (HDB) rating method…

1 Scope 1.1 The requirements of this Standard apply to materials, constructions, and testing of tree-retardant cross- linked polyethylene and ethylene propylene rubber-insulated single conductor or triplexed primary shielded and concentric neutral power cables rated 15 to 46 kV that are used for the transmission and distribution of electrical energy. The products covered by this Standard are…

1 Scope 1.1 This Standard applies to the materials, construction, and testing of one- to four-conductor cross-linked polyethylene and ethylene propylene rubber-insulated shielded power cables, rated 5–46 kV, that are used for the distribution of electrical energy under normal conditions of installation and service in indoor, outdoor, aerial, underground, or underwater locations. 1.2 This…

1 Scope 1.1 General 1.1.1 This Standard applies to occupational diving operations conducted in connection with all types of work and employment, and describes the requirements for occupational safety. Note: It is recognized that certain underwater tasks might require specialized standards of practice and/or operational techniques that differ from the requirements of this Standard yet may be…
