General methods of test for pigments and extenders - Part 5: Determination of oil absorption value (ISO 787-5:2026)
Scope: This document specifies a general method of test for determining the oil absorption value of a sample of pigment or extender. The oil absorption value is usually required to be compared with the value determined at the same time on an agreed sample of the product.

General methods of test for pigments and extenders - Part 5: Determination of oil absorption value
Scope: The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It should just spread without cracking or crumbling. Read the burette and note the quantity of oil used. The result is expressed in millilitres of oil per 100 g of product or in grams of oil per 100 g of product. - Cancels and replaces Part 5 of ISO/R 787-1968.

General methods of test for pigments and extenders - Part 18: Determination of residue on sieve - Mechanical flushing procedure (ISO/DIS 787-18:2026)
Scope: The method specified can also be applied to the examination of other powders or granules which are insoluble in water. It is neither applicable to hydrophobic nor pelletized materials. In the test apparatus the material under test, dispersed in water, is brought into centrifugal motion by a system of rotating jets of water. he water flushes the fine particles through the sieve, the coarse particles being retained on the sieve. The residue on the sieve is dried and weighed. - Cancels and replaces ISO 787/18-1973 and constitutes its technical revision.

General methods of test for pigments and extenders - Part 1: Comparison of colour of pigments (ISO/DIS 787-1:2026)
Scope: Procedure for comparing the colour of a coloured pigment with that of an agreed sample. The procedures described in this document are acceptable but the method using an automatic muller is the reference method. The binder is not specified. It shall be agreed between the interested parties. If no binder is agreed, linseed oil, complying with the specification in ISO 150, should be used. - Replaces ISO/R 787/1:1968.
