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. Notes: (1) In certain provinces there may be variations in size limitations quoted in this Standard. Consultation with the regulatory authority is recommended. (2) Cylinders, spheres,…

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.

This National Standard of Canada is equivalent to International Standard ISO 10993-2:1992. 1 Scope This part of ISO 10993 specifies minimum requirements for the use of animals in biological testing. This part of ISO 10993 is also intended a) to establish guidelines which allow the scientist to respect life in general; b) to reduce the number of animal experiments and the number…

1.1 SCOPE 1.1.1 This standard applies to newly produced, gas-fired, work activated, air conditioning and heat pumping appliances, hereinafter referred to as appliances, constructed entirely of new, unused parts and materials, which are designed to supply conditioned air; heated and/or cooled liquid; or refrigerants, gases, solids, or liquids to spaces remote from or adjacent to the…

1. Scope 1.1 This Standard describes requirements and test methods for materials, dimensions, quality of work, pipe stiffness, quality control, joining systems, and a form of marking for PVC (polyvinyl chloride) profile sewer pipe and fittings of pipe stiffness PS70 and PS320, based on controlled inside diameter. Notes: (1) Pipe and fittings produced to meet the requirements of this…

1. Scope Note: Pipe made to this Standard should not be used in the production of fabricated fittings, due to the lack of field data. 1.1 This Standard describes requirements and test methods for materials, dimensions, quality of work, pipe stiffness, quality control, joining systems, and marking for SDR 28, 35, and 41 multilayer PVC sewer pipe (PSM type). Note: Industrial waste…

1. SCOPE 1.1 These recommended practices provide guidance for the selection, use, maintenance, retirement, and understanding of the limitations of fireline workwear for protection against the adverse effects to the firefighter's body during forest firefighting. 1.2 The use of workwear for protection against the adverse effects of fire to the…
