International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cl

This third edition cancels and replaces the second edition (ISO 2535:1997), which has been revised to include four variants of the original method, calibration procedures for the device used to determine the gel time (see clauses A.2 and B.2) and precision data. Annexes A and B form a normative part of this International Standard. ENISO2535:2002
