Specifies the contents of register entries recording information about OSI document types, and assigning an unambiguous name of ASN.1 type object identifier to OSI document type definitions and the procedures for the operation of an international registration authority for OSI document types.

Applies to equipment for temporary earthing or earthing and short-circuiting of electrically isolated parts of a.c. installations, the disconnection of which has been verified, for the protection of workers while work is in progress using lance(s) as the earthing or earthing and short-circuiting device. Specifies the perfomance and safety requirements and tests for lance devices with matching…

The principle of the method specified is based on digesting with acid the particulate material collected on a filter, solubilizing any lead present und analysing the sample solution by atomic absorption spectrometry (AAS). The method is applicable to ambient air samples with particulate lead contents, such that the amount of deposited particulate lead collected on the filter is greater than 1 µg…

Contains standardized procedures for the calculation of the effects of short-circuit currents in two sections as follows: - the electromagnetic effect on rigid conductors and flexible conductors; the thermal effect on bare conductors. Only a.c. systems for rated voltages up to and including 420 kV are dealt with. The contents of the corrigendum of March 1995 have been included in this copy.

The types of E/VAC plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties vinyl acetate content and melt flow rate and on information about intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. Applies to all E/VAC copolymers containing from 3 % (m/m…

Preface Purpose: This is the third edition of Construction Plus. It supersedes the previous editions, which were published in 1988 and 1990. Construction Plus provides summaries of all CSA construction Standards and many construction-related Standards. Users of CSA's construction and construction-related Standards need to identify the basic content of each Standard quickly and…

Specifies a test method for determining the non-volatile matter content by mass of paints and varnishes, as well as resins and resin solutions that are intended for use as binders for paints and varnishes. Annex A gives required supplementary information, annex B describes the test conditions.

Specifies a procedure for total lead as lead alkyls at concentrations between 0,026 g and 1,300 g of lead per litre. The method is not apllicable to gasoline containing manganese anti-knock additives.

Applies to insulating hollow tubes made of synthetic materials and intended for tools and equipment for work on systems operating at voltages above 1 kV. The contents of the corrigenda of July 1999 and May 2000 have been included in this copy.

Applies to portable equipment, with or without matching fixed connection points, for temporary earthing or earthing and short-circuiting of electrically isolated a.c. transmission and distribution systems, including railway systems, for the protection of workers. Provides recommendations for manufacture, selection, use and maintenance of this equipment. The contents of the corrigenda of July…
