Relates to zinc phosphate pigments suitable for use in corrosion-inhibiting paints. Are classified as one of the following three types: loss on ignition at 600 ° centigrade greater than 8.5 % (m/m), but less than or equal to 10.0 % (m/m), loss on ignition at 600 ° centigrade greater than 10.0 % (m/m), but less than or equal to 13.0 % (m/m), loss on ignition at 600 ° centigrade greater than 13.0…
Plastics — Unplasticized cellulose acetate — Determination of moisture content
This determination may be required for the calculation of the dry mass used in analytical methods. Applies only to products with a moisture content of not more than 10 %. The principle consists in drying a test portion at 105 ° centigrade in a thermostatic oven, then weighing. The moisture content is calculated from the loss of mass of the test portion. Cancels and replaces the first edition ISO…
