This document specifies a thermogravimetric method for the determination of the main constituents of rubber compounds such as elastomer(s), carbon black and mineral filler.
It establishes the “fingerprint” of the tested material. However, the result does not always correspond exactly to the theoretical formula of the rubber.
This method applies to raw or compounded rubbers, vulcanized and unvulcanised, with or without extraction.
This method applies to rubbers with hydrocarbon backbones (NR, BR, SBR, IIR, EPDM, ACM, AEM, etc.) used alone or as mixtures. For the mixtures, the polymer content corresponds to the total rubber, and it is not usually possible to identify individual polymers.
This method applies to rubbers with halogenated hydrocarbon backbones (CR, CSM, FKM, CM, CO, ECO, etc.) or containing nitrogen (NBR, HNBR, NBR/PVC, etc.), as well as to their mixtures. However, these rubbers often form carbonaceous residues which interfere with the analysis. Application of an appropriate procedure minimizes these interferences.
This method also applies to rubbers with a polysiloxane backbone (VMQ, etc.) and to rubbers not listed above.

This document specifies a test method for assessing the peel strength of a thermoplastic elastomer (TPE) to a rigid substrate. It is mainly applicable to soft components in the Shore A hardness range.
This standard specifies a test piece but not the injection moulding tool for its manufacture. Hence, different results could be obtained for test pieces produced using different injection moulding tools.

This International Standard specifies the minimum requirements for rubber hoses used for transferring ammonia, in liquid or in gaseous form, at ambient temperatures from −40 °C up to and including +55 °C at a working pressure of 2,5 MPa (25 bar). It does not include specifications for end fittings, but is
limited to the performance of the hoses and hose assemblies.

This document specifies the minimum requirements for rubber hoses and hose assemblies for use in oil burners.
The following two types of hose assembly are specified:
— Type 1: Hose assemblies for flux and reflux, but not for insertion between the oil burner pump and the atomizing connection; maximum working pressure 1,0 MPa (10 bar); maximum oil temperature
100 °C.
— Type 2: Hose assemblies for insertion between the oil burner pump and the atomizing connection;
maximum working pressure 4,0 MPa (40 bar); maximum oil temperature 100 °C.
The hose assemblies specified in this document are not intended to be used, without special assessment, for purposes other than oil burner installations.

This document specifies the requirements for general-purpose textile-reinforced thermoplastics waterdischarge hoses.

This document establishes unambiguous abbreviated terms for commonly used rubber compounding ingredients of known, specific chemical composition.

This document describes methods of evaluating the resistance of vulcanized and thermoplastic rubbers to the action of liquids by measurement of properties of the rubbers before and after immersion in test liquids. The liquids concerned include current service liquids, such as petroleum derivatives, organic
solvents and chemical reagents, as well as reference test liquids.

This document specifies a method for the determination of the resistance of rubber to abrasion using the Improved Lambourn test machine.
The abrasion loss resulting from the slip caused by the difference in circumferential speed between a disc-shaped rubber test piece and an abrasive wheel, which are driven to rotate independently with
their circumferences pressed against each other by a specified load, is determined. The test result can be reported as a volume loss per abrasion test time or running distance, and/or as an abrasion resistance index compared to a reference compound.
As the Improved Lambourn test machine is capable of setting various abrasive conditions, such as slip rate, sliding speed and load, independently, this method is suitable for the evaluation of compounds for a range of rubber products, especially tyres, under a wide range of severity conditions. An example of the testing of tyre tread rubber is given in Annex A.

This International Standard specifies material requirements for preformed, solid vulcanized rubber structural gaskets in sealing and supporting applications for buildings.
NOTE Specifications for non-supporting gaskets are given in ISO 3934.

This document specifies the minimum requirements for textile-reinforced, smooth-bore rubber watersuction and discharge hoses and hose assemblies.
Three types of hoses and hose assemblies are specified according to their operating duty requirements, i.e. their ambient and water temperature ranges:
— ambient temperatures: −25 °C to +70 °C;
— water temperatures during operation: 0 °C to +70 °C.

- water temperatures during operation: 0 °C to +70 °C.

This document specifies a method for the generation of tyre and road wear particles (TRWP) in a road simulator laboratory that is representative of actual driving conditions. Guidance is provided for the road simulator system, test pavement and tyres, vacuum collection system, monitoring, and reporting.
This method is applicable for the collection of TRWP from a known pavement and tyre type under realistic driving conditions without the inference of road surface contaminants (i.e. brake dust, exhaust, grease, etc.).
There is a possibility that this method is not relevant for studded tyres.

This document specifies the minimum requirements and the test methods for meteorological balloons made from natural rubber latex or natural rubber latex compounded with synthetic rubber emulsion.
This document applies to two types of balloons:
— Type 1: meteorological balloon by dipping process;
— Type 2: meteorological balloon by moulding process;
