Applies to portable voltage detectors with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 420 kV a.c. and frequencies from 15 Hz to 60 Hz. For the time being, it has been identified that : - For voltage levels up to 52 kV, the actual standard can be used in its entirety ; - For voltage levels above 52 kV, electric testing procedures are questionable…

Computer security is divided into four areas: security with regard to installation and operation; system security; security with regard to document contents; security with regard to communication. The use of this standard is intended to facilitate communication with quality assurance functions within the company and outside, consideration of the different security aspects in the design work,…

Provides guidelines for establishing new routines required for the production of design documentation. The routines apply to manual as well as computer-based design work, but are particularly important when computers are used. The following phases are characterized: development phase, approval phase, distribution phase, storage phase, revision phase, phasing out. The use of this standard…

1.1 This Standard covers 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, or threaded Schedule 40 and 80 fittings, and fittings that have been fabricated for use with any jointing method. Note: If PVC pipe and fittings are to be used in other…

Describes the grey scale for determining staining of adjacent fabrics in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. The essential scale (5 steps) consists of pairs of non-glossy grey or white colour chips (or swatches of grey…

Describes the grey scale for determining changes in colour of textiles in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. The essential scale (5 steps) consists of pairs of non-glossy grey colour chips (or swatches of grey cloth…

1. Scope 1.1 This Standard provides the examination and testing requirements that will apply to the work of any organization participating in the construction, installation, and fabrication of parts or components of concrete containment structures, or both, that are defined as class containment.

1.1 This Standard establishes minimum requirements for all electrical work and electrical equipment operating, or intended to operate, in mines and quarries. 1.2 This Standard is intended to be used in conjunction with CSA Standard C22.1, the requirements of which apply unless modified in this Standard.

1.1 This Standard applies to flexible liquid-tight nonmetallic conduit and fittings in trade sizes 3/8 to 2 intended for use as a receway for the installation of conductors in accordance with the Rules of the Canadian Electrical Code, Part I, for nonhazardous locations. 1.2 Flexible liquid-tight nonmetallic conduit covered by this Standard has a reasonable smooth interior, is liquid-tight,…

1.1 This Standard specifies the minimum requirements for factory-built, single or multiple-piece roof vent flashings used to effect a permanent weather seal between the flashing and the vent pipe without the use of additional sealing materials around the vent pipe. Flashings fabricated on-site are not included. 1.2 The Standard includes requirements for material, quality of work, and…
