Preferred Voltage Levels for AC Systems, 0 to 50 000 V
1. Scope
1.1 This Standard establishes voltage standards for AC Systems in Canada to provide a guide:
(a) To national committees on utilization and control equipment or devices for establishing standard ratings of such equipment or devices on a basis coordinated with standard systems;
(b) To system designers so that new systems will be designed to accommodate standard ratings of…
1. Scope
1.1 This Standard applies to cord connected and direct plug-in transformers for use indoors, designed to be used on a nominal 120-V branch circuit in nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I, and intended to supply power for the operation of extra-low voltage toys or hobby equipment.
For convenience, the shorter term transformer is…

Caseins and caseinates — Determination of scorched particles content
Specifies a method on the principle of dissolution of a test portion in hot sodium carbonate, sodium polyphosphate or disodium ethylenediaminetetraacetate solution, or in sodium hydroxide solution at room temperature or at 60 degrees centigrade, filtration of the solution through a filtering disk and visual comparison of dried disk with scorched particle standard disks. The testing of filtering…
Agricultural tractors and machinery — Track widths
This International Standard cancels and replaces ISO Technical Report ISO/TR 4004-1975. Applies to the principal driven axle(s) of tractors and to macinery, including self-propelled machinery, uesd in fields for row-crops. It does not apply to tractors of special types, to walking tractors, to single-axle motor-driven machines, to two-wheeled propulsion units, or to agricultural machinery of…
Steels — Micrographic determination of the ferritic or austenitic grain size
Specifies the methods for revealing the grain and for estimating the mean size of the grain revealed. Includes a counting method (annex A) and determination of grain size by using of standard charts (annnexes B and C) taken from an AFNOR Standard and an ASTM document, respectively.
