This International Standard give guidelines for the inspection, recording procedures, packaging and storage of products, assemblies and components made from vulcanized or thermoplastic rubber prior to being put into circulation.

It is applicable to both solid and cellular rubber products prepared from dry raw rubber, latex or other sources. It is subject only to the requirements or recommendations of product specifications in which details of storage requirements for specific products are given. This standard is not intended for use with raw rubber in bale, liquid (solution or emulsion) or particulate form, storage guidance for which is given in ISO 7664.

The recommendations for packaging form an integral part of the controlled storage procedure, as well as providing means of identifying the material and product.

This document specifies methods for determining the amount of sulfur volatilized from vulcanized rubber under heating conditions using high performance liquid chromatograph (HPLC). The methods apply only to the sulfur which chemical formula is S8. The methods cannot be used above the thermal decomposition temperature of the rubber. Note 1 This methods determine the amount of sulfur that volatilizes from the vulcanized rubber under heating conditions, and do not determine the total amount of sulfur that can volatilize from the vulcanized rubber. Note 2 Depending on the method adopted to collect sulfur volatilized from vulcanized rubber, the test results can be different between the two methods.

This document specifies methods for determining the amount of sulfur compounds volatilized from vulcanized rubber under heating conditions using gas chromatograph (GC) or ion chromatograph (IC). The methods apply to the sulfur compounds which are hydrogen sulfide (H2S), carbonyl sulfide (COS), carbon disulfide (CS2) and sulfur dioxide (SO2). The methods cannot be used above the thermal decomposition temperature of the rubber. Note The methods determine the amount of sulfur compounds that volatilize from the vulcanized rubber under heating conditions, and do not determine the total amount of sulfur compounds that can volatilize from the vulcanized rubber.
