Continuous forms used for information processing — Sizes and sprocket feed holes
Describes the sizes of continuous forms and the diameter and location of the sprocket feed holes. Applies to paper in continuous lengths intended for use with automatic data processing equipment for print-out of documents for administrative, commercial and technical use. References: ISO/R 187; ISO/R 215.
The method relates to a product packed in sacks, but it also gives the procdure to be followed for sampling in bulk. It first gives definitions of relevant terms. Then it gives general information specifies the apparatus, the method of sampling, the packing marking and dispatch of samples. Three figures show examples of suitable apparatus.
Paints and varnishes — Determination of viscosity at a high rate of shear
Describes a procedure for determining the viscosity of coating materials and related products at a rate of shear not less than 5000 s-1 and not higher than 20000 s-1. When products are being compared the rate of shear shall be approximately the same. The test shall be made at a closely controlled temperature unless otherwise agreed. The value obtained gives information about the resistance of the…
