Describes procedures for classifying elastomeric parts for primary packs and medical devices used in direct contact with preparations for parenteral use, including both aqueous preparations and dry preparations which have to be dissolved before use.

1.1 This part of ISO8871 defines procedures for classifying elastomeric parts for primary packs and medical devices used in direct contact with preparations for parenteral use, including both aqueous preparations and dry preparations which have to be dissolved before use.

It specifies a series of comparative test methods for chemical evaluation by the determination of extractables in aqueous autoclavates (see Clause4) and describes the various fields of application for elastomeric parts. Dimensions and functional characteristics are specified in the relevant International Standards. Required properties as specified in this part of ISO8871 are regarded as minimum requirements.

1.2 This part of ISO8871 is applicable for the categories of elastomeric parts given in Clause3; specific requirements, however, are laid down in the relevant International Standards dealing with the items or devices listed in Clause3.

Elastomeric parts for empty syringes for single use are excluded from the scope of this part of ISO8871 as they are not in contact with the injected preparation for a significant length of time.

1.3 Compatibility studies with the intended preparation have to be performed before the approval for final use can be given; however, this part of ISO8871 does not specify procedures for carrying out compatibility studies.
