Describes Work area cord for class D applications, as defined in ISO/IEC 11801 as well as in the ISO/IEC 24702. Should be used in conjunction with IEC 61156-1 and IEC 61156-6 and IEC 60603-7-2 and 60603-7-3. The blank detail specification determines the layout and style for detail specifications describing symmetrical pair/quad cables with transmission characteristics up to 100 MHz for digital…

Demonstrates how to estimate the uncertainty of steady-state temperature and humidity conditions in temperature and humidity chambers. Since this is inextricably linked to the methods of measurement, these are also described. This standard is equally applicable to all environmental enclosures, including rooms or laboratories. The methods used apply both to temperature chambers and combined…

The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions. There are numerous methods of encoding information in bar code form, known as symbologies. Code 39 is one such symbology. The rules defining the translation of characters into bar and space patterns and other essential features are known as the symbology specification. In the…

ISO 1209-1:2007 specifies a simple method for assessing the behaviour of a bar of rigid cellular plastic under the action of three-point bending. It may be used to determine either the load for a specified deformation or the load at break. The version of the method specified uses small test specimens and does not produce pure bending. Hence it does not permit the calculation of the flexural…

ISO 21348:2007 specifies the process for determining solar irradiances and is applicable to measurement sets, reference spectra, empirical models, theoretical models, and solar irradiance proxies or indices that provide solar irradiance products representing parts or all of the solar electromagnetic spectrum. Its purpose is to create a standard method for specifying all solar irradiances for use…

1 Scope 1.1 This Standard specifies the chassis and body requirements and safety equipment requirements for school buses. Notes: (1) The main purpose of this Standard is to provide the safest possible vehicle for students using school buses. It needs to be stressed, however, that standards are not substitutes for thorough, ongoing, and comprehensive safety training of students and drivers. (2)…

1 Scope 1.1 This Standard specifies maintenance requirements and service intervals for elevators, dumbwaiters, escalators, and moving walks where the original manufacturer's recommendations are not available or where there is insufficient data on the age, quality, and operation of the equipment. 1.2 This Standard is intended for use in conjunction with ASME A17.1/CSA B44. 1.3 In…

1 Scope 1.1 This Standard covers (a) automatic transfer switches; (b) manual transfer switches; (c) closed transition transfer switches; (d) hybrid transfer switches; (e) transfer switches for fire pumps; and (f) bypass/isolating switches that have a maximum rating of 750 V, are for use in non-hazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I, and enable…

Applicable to vacuum cleaners for household use in or under conditions similar to those in households. The purpose of this standard is to specify essential performance characteristics of vacuum cleaners being of interest to the users and to describe methods for measuring these characteristics.
