ISO 17051:2020 Rubber, vulcanized – Guidelines for material specification

CDN $347.00

Description

This document establishes guidelines for the specification of vulcanized rubber based on the properties of individual rubber types. This document helps users of rubber products, who are not rubber experts, to create a specification for the rubber materials they wish to use.

It also describes a designation system to enable a line call-cut code to be devised for each specification.

Since the properties of rubber depend on the type of rubber, such as composition, some rubbers are classified into several types and organized by hardness.

Representative specifications for the following rubber types are given in Annexes B to M: natural rubber (NR), styrene butadiene rubber (SBR), nitrile rubber (NBR), hydrogenated nitrile rubber (HNBR), nitrile rubber mixed with PVC (NBR/PVC), chloroprene rubber (CR), ethylene acrylic rubber (AEM), fluorocarbon rubber (FKM), silicone rubber (VMQ), epichlorohydrin rubber (ECO) and ethylene propylene rubber (EPM and EPDM).

In cases of mixed rubber polymers, the main polymer in the rubber material gives the name of the rubber type.
