# Rubber Gaskets and Seals Accreditation Guide

The rubber gaskets and seals industry in the UK is primarily governed by quality and materials standards rather than a single trade body. ISO 9001 certification is the most widely recognised accreditation, demonstrating that a manufacturer or supplier operates a quality management system meeting international standards. Additionally, suppliers may hold ISO 3384 accreditation, which specifically relates to compression set testing of elastomers, or ISO 1817 for resistance to fluids. For companies serving the aerospace, automotive, or food sectors, accreditations such as AS9100, IATF 16949, or British Retail Consortium (BRC) certification are increasingly important. The Rubber Manufacturers Association (RMA) and the Institute of Materials, Minerals and Mining (IOM3) also provide guidance and professional recognition within the sector, though formal accreditation through these bodies is less common than ISO compliance. Understanding which standards apply to your specific application—whether it is food-contact seals, chemical resistance, or high-temperature performance—is essential when selecting a provider.

To verify a supplier's credentials, request copies of current accreditation certificates and check the issuing body's register directly; many accrediting organisations maintain searchable databases where you can confirm valid certifications. Ask whether accreditations cover the specific products you need, as a company may hold ISO 9001 but lack certification for particular material grades or testing methods relevant to your application. Legitimate providers will be transparent about their credentials and willing to provide evidence of third-party audits and compliance. This verification matters considerably because accredited suppliers are subject to regular independent inspections, documented quality procedures, and accountability; they are also more likely to meet delivery specifications consistently and maintain traceability for batch testing, which reduces the risk of costly failures or supply chain disruption.
