1.1 All exit devices shall be listed or labeled by a nationally recognized independent testing laboratory and be subject to periodic examination service. 1.2 Exit devices are available in Grades 1 and 2, both suitable for all classes of buildings and are based on the performance tests listed. 1.3 The cycling requirements listed are not to be considered as being in addition to the one…

La présente norme nationale du Canada est équivalente à la norme national américaine ANSI/BHMA A156.3-1984. 1.1 Tous les dispositifs d'ouverture de porte d'issue doivent être listés ou étiquetés par un laboratoire d'essai indépendant reconnu sur le plan national et être soumis à des inspections périodiques. 1.2 Les dispositifs d'ouverture de porte d'issue sont…

Establishes a consistent repeatable means of evaluating characteristics of an operator protective structure under loading, and prescribes performance requirements for this structure under such loading in a representative test. Applies to mobile forestry machines and equipment defined in ISO 6814.

Applies to the technical documentaion to be supplied with electrical and electronic measuring equipment for use in laboratories and for testing and servicing. Replaces IEC 60278 and IEC 60278A.

Its use is mandatory for the calibration of secondary standard pyranometers according to ISO 9060, and is recommended for the calibration of pyranometers which are used as reference instruments in comparisons. Is intended for use by test institutions or test laboratories equipped with well-maintained pyrheliometers and is applicable to all pyranometers. The object is to promote the uniform…

1.1 The Canadian Standard Freeness test is designed to give a measure of the rate at which a dilute suspension of pulp may be dewatered. The drainage rate, or freeness, has been shown to be related to the surface conditions and swelling of the fibres, and is a useful index of the amount of mechanical treatment given to the pulp. 1.2 The procedure was originally designed to yield a test value…

The principle of the method specified is conditioning the extract solution to be analyzed, developing the blue silicomolybdate complex using ammonium molybdate and a reducing solution, measuring the optical density of the resulting colour complex by means of a molecular absorption spectrometer at 800 nm using 10 mm optical cells. Measures the concentrations of silicon, expressed as its oxide SiO2…
