This measurement is a method for comparing the resistance to abrasion with that of a standard test specimen or, alternatively, an agreed specimen by the use of a jet of particles. Different batches of abrasive particles are liable to give different results and this is the main reason for the test being a comparative one. The method is applicable to all anodic oxidation coatings of thickness not…

This International Standard specifies a preferred method and an alternative method for measuring the signal-to-noise ratio of 8 mm type S, 16 mm and 35 mm variable-area photographic Sound records.

1. OBJECT AND SCOPE The object of this standard is to establish requirements for dimensions, characteristics and test methods relating to rigid* pipe and fittings, manufactured from PVC compounds, used in underground applications for conveying liquids under no pressure. It covers rigid, non-perforated, smooth interior wall (see note 1), pipes and fittings with a nominal diameter equal…

1. OBJECT AND SCOPE The object of this standard is to establish requirements for dimensions, characteristics and test methods relating to PVC plastic perforated pipe and fittings used for underground gravity disposal of waste water. It applies to rigid and fittings with smooth interior wall, generally equipped with sockets for solvent cement assembly. This standard is specifically…

Covers a group of common requirements that shall apply, unless otherwise specified in a purchase order or in an individual standard, to structural quality steel plates, shapes, hollow sections, sheet piling, and bars conforming to the requirements of CSA Standard G40.21.

Covers a group of common requirements that shall apply, unless otherwise specified in a purchase order or in an individual standard, to structural quality steel plates, shapes, hollow sections, sheet piling, and bars conforming to the requirements of CSA Standard CAN/CSA-G40.21-M.

1. Scope 1.1 General This Standard applies to airborne and liquid effluents associated with the normal operation of CANDU Nuclear Power Plants. It provides guidelines and a methodology for calculating the upper limits (the Derived Release Limits) for the rate of release of radionuclides discharged into the atmosphere and surface waters, based on limiting radiation exposures to members…

1. Scope 1.1 This Standard consists of primary and supplementary graphic and control sets, 7-bit and 8-bit codes based on the above sets, and rules for code extension. The character sets are intended for general usage in data processing, programming, and information interchange. These character sets include letters, fi gures, punctuation marks, and other symbols and controls, with their…

Establishes the mounting dimensions for interchangeability of starter motors mounted on internal combustion engines. Applies to starter motors, types 1 to 4, sizes "A" and "B". May be used for other engine applications where no specific standards exist. Some figures illustrate shapes and reference quantities of concern.

Lays down the dimensional tolerances on non-standard discs, belts and other cross-sections for coated abrasive products. The dimensional tolerances on standardized products are specified in ISO 1929, ISO 2235 and ISO 3017. Contains a graph for reading of tolerances on other cross-sections and gives the measurement conditions.
