This National Standard of Canada is equivalent to International Standard ISO 1100-2:1982. This International Standard specifies methods of determining the stage-discharge relation for a gauging station. A sufficient number of discharge measurements complete with corresponding stage measurements is required to permit the stage-discharge relation to be determined to the accuracy required by this…

This National Standard of Canada is equivalent to International Standard ISO 1088:1985. This International Standard specifies a standard basis for the collection and processing of data for the determination of individual components of the total error in the measurement of liquid flow in open channels by velocity-area methods. For determining the discharge in open channels by the velocity-area…

This National Standard of Canada is equivalent to International Standard ISO 6741-1:1989. This part of ISO 6741 specifies methods for the determination of the commercial mass of homogeneous consignments of those textile fibres and yarns composed of a single generic species listed in part 4. The methods specified in this part of ISO 6741 do not apply to beamed yarns, to coated yarns, to fibres…

This National Standard of Canada is equivalent to International Standard ISO 6741-2:1987. This part of ISO 6741 specifies methods for obtaining laboratory samples for mass determination by one of the methods given in ISO 6741-1. The method appropriate for particular fibres is indicated in ISO 6741-4. The procedures comprise: Nature of Consignment Procedure described…

This National Standard of Canada is equivalent to International Standard ISO 6741-3:1987. This part of ISO 6741 specifies specimen cleaning procedures to be used when the commercial mass is to be determined in accordance with ISO 6741-1 on a clean and dry basis. The procedure appropriate for a particular fibre is given in ISO 6741-4. If the commercial mass is to be determined on a dry-…

This National Standard of Canada is equivalent to International Standard ISO 2647:1973. This International Standard specifies a method of test for determining the percentage of medullated wool fibres by means of the projection microscope. The method is applicable to woollen and worsted products, at all stages, from raw materials to yarn.

This National Standard of Canada is equivalent to International Standard ISO 2648:1974. This International Standard specifies a method for the determination of fibre length distribution parameters, principally mean length and the coefficient of variation of length, for all-wool slivers and rovings. The method is not directly applicable to slivers made up of a blend of two or more fibres…

This National Standard of Canada is equivalent to International Standard ISO 2649:1974. This International Standard specifies a method applicable for the determination of short-term irregularity of linear density of yarns, rovings and slivers of pure wool, from 5 tex up to 40 kilotex. The method is not directly applicable to fibre blends.

This National Standard of Canada is equivalent to International Standard ISO 2916:1975. This International Standard specifies a method for the determination of the alkali content of wool. The method is applicable to undyed wool in any form; for example, loose fibres, card sliver, tops, yarn or fabric. It can be used with dyed wool if the amount of dye extracted in the course of the…

This National Standard of Canada is equivalent to International Standard ISO 3073:1975. This International Standard specifies a method for determining the acid content of a wool sample, expressed as a percentage by mass. This method is applicable to undyed wool in any form, for example loose fibre, sliver, yarn or fabric. It is also applicable to dyed wool when the amount of dye…
