1. Scope 1.1 The Standard sets out requirements for macrocomposite pipes 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…

1. Scope 1.1 The Standard sets out requirements for macrocomposite pipes consisting of a welded aluminum tube laminated by a melt adhesive to layers of crosslinked 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 cold- and hot…

Object The object of this Code is to establish safety standards for the installation and maintenance of electrical equipment. In its preparation, consideration has been given to the prevention of fire and shock hazards, as well as proper maintenance and operation. Compliance with the requirements of this Code and proper maintenance will ensure an essentially safe installation.…

This National Standard of Canada is based on International Standard CEI/IEC 598-2-19:1981 (first edition, 1981), including Amendments 1:1987, and 2:2002. Note - Amendment No. 2 reaffirmed 2007-03-28. 19.1 Scope This section of Part 2 of IEC Publication 598 specifies safety requirements for air-handling luminaires for use with a ventilation duct or ventilated space (plenum), for use with…

1. Scope 1.1 This Standard applies to occupational diving operations conducted in connection with all types of work and employment, and describes the requirements for minimal competency levels for all personnel directly associated with the identified techniques of diving. Canadian safety and health legislation requires that all workers be competent to perform the work assigned to them.…

Scope Part I 1.1 Except as provided for in Clause 1.2, this Standard applies to all boilers, pressure vessels, fittings, and piping, as provided for by the Act and defined in this Standard.

1. Scope 1.1 This Standard sets out minimum requirements for serially produced light-weight refillable gas cylinders, original equipment and conversions, having a water capacity exceeding 20 L (1220 in³) but not exceeding 1000 L(35.5 ft³). The cylinders are intended only for the onboard storage of high-pressure compressed natural gas as a fuel for automotive vehicles to which the…

1. SCOPE 1.1 This standard applies to task chairs for office work with Visual Display Terminals (VDT) by providing dimensional requirements and methods for measuring chairs and assessing their performance. 1.2 This standard describes the chair types for three levels of single-shift use: Type 1 - Use of the computer and of other equipment is the primary task of the user,…

1. Scope 1.1 This Standard covers cross-linked 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: Pressure rating for water at 23°C and 93°C is given in Appendix A. 1.2 The components covered by this…

Is applicable to voltage detecting systems that are single-pole and are capacitively-coupled to live parts. They are used to detect the presence or absence of operating voltage on a.c. electrical systems for voltages from 1 kV to 52 kV, and for frequencies from 16 2/3 Hz to 60 Hz. This standard is also applicable to phase comparators designed for voltage detecting systems.
