Determines the lead content of leaded and unleaded gasolines. Lead in the range of 1.0 to 1100 mg/L can be measured.

This National Standard of Canada is equivalent to International Standards ISO 8879-1986 and ISO 9069-1988. 1 Scope This International Standard: (a) Specifies an abstract syntax known as the Standard Generalized Markup Language (SGML). The language expresses the description of a document's structure and other attributes, as well as other information that makes the markup…

Applies to panels intended for covering internal walls which may be grouped into five classes according to their constitution (siehe ISO 633). Specifies the following characteristics: dimensions, squareness and straightness of edges, moisture content, handling behaviour, resistance to boiling water and resistance of glued joint which shall in the classes IV and V not show any unglueing when…

The method is applicable to vandadium contents between 0,005 % (m/m) and 1,0 % (m/m), provided that the tungsten content in the test portion is not higher than 10 mg and/or the titanium content is not higher than 5 mg. Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. The annexes give additional information on the international co-operative…

The determination is carried out in the following way: Decomposition of the soap by sulfuric acid and extraction of the fatty acida with light petroleum. Oxidation of the free glycerol remaining in the aqueous phase by periodic acid to formic acid and formaldehyde. On reaction with chromotropic acid, the aldehyde formed gives an absorbing compound whose absorbance is propotional to the free…

The water in a test portion is removed by azeotropic destillation with boiling xylene or petroleum. The volume of the water collected is measured. The method is applicable to products in the form of powders having water contents greater than 5 % (m/m), and in the form of pastes ans solutions. It is not applicable to samples containing water-soluble volatile compounds, for example ethanol.

Specifies a method for the determination of total sulphur in natural gas. It is applicable to gases with sulphur contents between 0,5 mg/m3 and 1 000 mg/m3. With a total sulphur content of more than 0,1 mg sulphur in the absorption solution, visual titration with an indicator can be chosen, whereas for lower contents turbidimetric titration is preferable.

The method is intended to be applied at the places of dispatch and/or acceptance of the ore. Annex A specifies a method to be used in the case of adhesive or wet manganese ores. Annex B specifies methods of correction for sprinkled water and/or rain-water. Cancels and replaces the first edition (ISO 4299:1980) of which it constitutes a minor revision.

Acceptance criteria are given for the package when tested by specified methods. These methods not only provide a measure of the effectiveness of the package in restricting access by children but also cover the accessibility to the contents by adults. Reclosable packages for any product intended to be exposed or removed from the packages are covered by the procedures. Means of performing the test…
