This document specifies a system of classification of materials used in preformed gaskets for buildings. It applies to the following products: a) gaskets for use round the inside of door or window casings, i.e. weatherstripping (dynamic gaskets); b) gaskets for glazing (static gaskets); c) gaskets for use round infilling; d) gaskets for use between facade parts; e) gaskets for use between masonry walls. In addition to specifying the characteristics required for the constituent materials, some functional tests on the gaskets themselves are specified. The corresponding test procedures are given in Annexes A to E. This document applies to preformed gaskets made from vulcanized or thermoplastic rubber. It also applies to preformed gaskets made of cellular rubber designed for use at temperatures between −20 °C and +55 °C (thermal conditions category P1) and between −40 °C and +70 °C (thermal conditions category P3) (see Clause 4).

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.

ISO 6072:2011 specifies test methods for evaluating the effect of hydraulic fluids on standard elastomeric materials that have been manufactured in accordance with specified processes. It allows baseline comparisons of fluids with standard elastomers. 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.

ISO/TR 7620:2005 describes a classification system for the reporting and tabulation of the chemical resistance of rubber materials. It also provide guidance on the testing and evaluation of rubber with particular reference to test chemicals described in a number of ISO standards. It gives guidance on the behaviour of rubber in contact with chemicals such as aggressive gases and fluids, e.g. acids, alkalis, aqueous solutions, oil and solvents. The information given is based on the practical experience of manufacturers and users of rubber materials.

Intended as a guide to the behaviour of this material in contact with chemicals as aggressive gases and fluids, e.g. acids, alkalies, solvents, etc. This information is based on practical experience of manufacturers and users and summarized in tables. Without prior knowledge or experience of application, table-based selections should be confirmed by tests, where attention should be paid to the possibility of rubber contaminating the liquid or gas. Annex with references and tables.

Does not cover design or dimensions of seals, but tolerances should be described in accordance with ISO 3302. Is based on experience with chloroprene rubber. Work is in progress to take account of material development in this field. The requirements are summarized in a table. The annex refers to the determination of recovery.
