Two precision determination methods are given that are described as 'robust' statistical procedures that attempt to eliminate or substantially decrease the influence of outliers. The first is a 'level 1 precision' procedure intended for all test methods in the rubber manufacturing industry and the second is a specific variation of the general precision procedure, designated 'level 2 precision', that applies to carbon black testing. Both of these use the same uniform level experimental design and the Mandel h and k statistics to review the precision database for potential outliers. However, they use slight modifications in the procedure for rejecting incompatible data values as outliers. The 'level 2 precision' procedure is specific as to the number of replicates per database cell or material-laboratory combination.

The guidance provided by ISO/TR 24699 is intended primarily for use by standards writers. Over and above its primary purpose, however, ISO/TR 24699 provides guidance of value to those involved in design work and other activities where the environmental aspects of rubber and rubber products are being considered. It promotes the use of renewable, recycled and recyclable materials when environmentally beneficial and includes guidance on compliance with legislation concerning the end-of-life treatment of rubber products and the management of restricted and prohibited substances.

The standard provides formulations, mixing procedures and vulcanization procedures for five types of elastomeric composition: acrylonitrile-butadiene rubbers (NBR 1 and NBR 2), fluorocarbon rubber (FKM 2), ethylene propylene diene rubber (EPDM 1) and hydrogenated acrylonitrile-butadiene rubber (HNBR 1).

These procedures evaluate the effect of mineral-based, fire-resistant and biodegradable hydraulic fluids on such compositions by measurement, under controlled conditions, of physical properties of standard test pieces of the elastomer before and after immersion in the fluids.

The standard does not provide formulations of elastomeric materials for actual service, although service elastomers may be tested using these compatibility procedures if required.
