1.1 This standard covers the inspection and test methods for the verification of dimensional, mechanical and physical properties of flat, corrugated, grooved or fluted asbestos-cement sheets, as well as those of shingles, bulkheading, molded roofing sheets and pavements tiles. 1.2 This standard includes the following control and testing methods : a) control of geometric…

La présente Norme internationale fixe les cotes maximales et minimales des colliers en P fixés à l'aide d'une vis de diamètre nominal 5 mm. Les dimensions fixées définissent une enveloppe dimensionnelle. La présente Norme internationale ne doit pas être considérée comme une norme d'interchangeabilité. Les tolérances pour chaque type de collier sont à définir dans les dessins de…

Describes the method used to determine the coefficient of permeability of a soil at the end of a casing. The test consists in injecting water using gravity, into a soil through the lower opening of a drilling casing. This opening is located below the local piezometric level. Two test methods are described in the standard: a) the constant head method; b) the variable falling head…

1. Scope 1.1 This Standard applies to the integrated measurement of the concentration of total mercury (particulate and vapour phase) in ambient air over a concentration range of 5 to 5000 ng·m-3. The sampling time and/or flow rate must be adjusted so that the amount of mercury collected is within the linear range of the detector. 1.2 The method consists of the following steps: (…

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…

1. Scope 1.1 This Standard applies to fixed equipment or accessories, or both, that utilizes signals to measure or control directly or indirectly an industrial process through a final control device (or devices) and is intended to be connected to supply circuits with voltages of 750 V and less, for use indoors or outdoors in nonhazardous locations in accordance with the Canadian Electrical…
