Oil of calamus — Determination of cis-beta-asarone content — Gas chromatographic method on packed co...
A small quantity of the oil is analyzed under specified conditions. The cis-beta-asarone contents is determined by using the internal standard or addition method. As stationary phase polyethylene glycol 20000 is used. Operating temperatures: Oven: isotherm about 190 °C. Injection system and detector: about 170 °C.
Related to two types of sheetings: open cell material and closed cell material. They are graded according to hardness index. For type 1 sheeting a single hardness level is specified, but for type 2 sheeting a range. For sheeting up to approximately 100 mm the material indentation hardness index is specified. For type 2, mostly available in thicknesses much less than 50 mm, it is necessary to use…
Oils of lemon and petitgrain citronnier, and oil of lime obtained by a mechanical process — Determin...
The method consists in analyzing a small quantity of essential oil on a column of small diameter but great length under specified conditions. The citral content is determined by using the internal standard method. Polyethylene glycol 20000 is used as stationary phase. Operating temperatures: Oven: linear temperature programming from 80 to 180 °C at a rate of 2 °C/min. Injection system: about 190…
Oil of rosewood — Determination of alpha-terpineol content — Gas chromatographic method on packed co...
A small quantity of the oil is analyzed by gas chromatography under specified conditions on a packed column. The
alpha
-terpineol content is determined by using the internal standard method. Operating temperatures: Oven: isotherm between 120 and 150 °C. Injection system: about 170 °C. Detector: about 170 °C.
Canada Standard System for Sizing Girls' and Boys' Apparel
This standard describes the basic Canada Standard sizing system for determining the body size of boys' and girls'. It outlines the development of the system and provides in tabular form body measurements in metric units for standard size ranges covering practically all male and female members of the population from about two to three years of age until they reach their middle to upper…

Water quality — Methods of biological sampling — Guidance on handnet sampling of aquatic benthic mac...
Specifies equipment and procedures in shallow waters (down to a depth of about 1,5 m) which are accessible either by wading or from a bank or boat. The procedures are applicable to all accessible aquatic habitats in rivers, streams, poinds, estuaries and lake shores.
Sound system equipment. Part 13: Listening tests on loudspeakers
Applies to loudspeakers intended for household systems and environments. Although specifically designed for loudspeakers that are separate sound system components, the procedures, with minor changes, are applicable also to other devices such as radio receivers and television sets. Gives recommendations for the setting up, performance and evaluation of listening tests on loudspeakers.…
Paints and varnishes — Determination of "soluble" metal content — Part 7: Determination of...
The principle consists in oxidation of the of hte mercury compounds contained in the test solution obtained from the pigment portion of the paint or combustion with oxygen in an enclosed system of the evaporation residue of the test solution obtained from the liquid portion of water-dilutable paints. Reduction of the mercury(II) compounds to elementary mercury. Determination of the mercury, as…

The principle of the AAS method consists in aspiration of the test solution into an acetylen/air flame. Measurement of the absorption of the selected spectral line, emitted by a lead hollow-cathode or lead discharge lamp, in the region of 283,3 nm. The principle of the dithizone method consists in extraction of the lead from the test solution with an solution of dithizone in 1,1,1-trichloroethane…
