1 PURPOSe This document defines the specific requirements for the sampling of products to be tested, and to which laboratories and inspection organizations have to comply in order to be accredited for sampling by the Bureau de normalisation du Québec. Accreditation in specific sampling areas for which an application has been submitted shall be granted subject to conformity with the…

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…

The principle of the method specified is measuring the portion of the 422,7 nm line absorbed by calcium atoms and of the 285,2 nm line absorbed by magnesium atoms using a flame atomic absorption spectrometer, and comparison with the absorption produced by reference solutions. Measures the concentrations of calcium and magnesium, expressed as their oxides CaO and MgO. Applies to the analysis of…

The principle of the method specified is complexing of the aluminium in the extract solution to be analyzed with chromazurol S, measuring the optical density of the resulting solution by means of a molecular absorption spectrometer at 545 nm using 10 mm optical cells. Measures the concentration of aluminium, expressed as its oxide Al2O3. Applies to the analysis of extract solutions obtained from…

The principle of the method specified is complexing of the boron in the extract solution to be analyzed with azomethine H, measurement of the optical density of the resulting colour complex by means of a molecular absorption spectrometer at 415 nm using 20 mm optical cells. Measures the concentration of boron, expressed as its oxide B2O3. Applies to the analysis of extract solutions obtained from…

1.1 This standard applies to the dimensions of hospital, laboratory, storemen and general purpose smocks for wear by men. 1.2 Size dimensions cover 5 cm frequency chest girth sizing. An abbreviated range (small, medium, large) is also indicated. 1.3 A maximum residual garment shrinkage of 2% has been recognized in specifying the dimensions.

Specifies a test method that simulates a fire that under well ventilated conditions starts in a corner of a small room with a single open doorway. The method is intended to evaluate the contribution to fire growth provided by a surface product using a specified ignition source. It is especially suitable for products that for some reason cannot be tested in a small laboratory scale, e.g.…

Of the test methods presented (strength test for the structure, endurance test), only some may be required depending on the type of tyre to be tested. The tests are carried out in a laboratory under controlled conditions. Applies to all truck and bus tyres.
