API 6A & ISO10423 Elastomers

The current API 6A specification is a modified adoption of the English version of ISO 10423:2003. ISO 10423 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, SC 4, Drilling and production equipment which was based on the prior API Specification 6A, 17th Edition.

API 6A / ISO 10423, Appendix F immersion procedure provides a standardized method to evaluate polymer compounds for service in liquids and gases representative of the intended application environment. The test parameters that can be selected are the composition of the gas/liquid phase and the test temperature. While the test media is determined by the appropriate API 6A Material Class, the temperature used corresponds to the API 6A Temperature Class.

API 6A / ISO 10423 Appendix F.1.13.5.2 sour fluid: Petroleum and natural gas industries - Drilling and production equipment - Wellhead and Christmas tree equipment immersion testing - standard test fluids for non-metallic seals:

• Material class DD/EE - Gas phase mixture:  10% H₂S + 5% CO₂ + 85% CH₄  
• Material class FF/HH - Gas phase mixture: 10% H₂S + 80% CO₂ + 10% CH₄

API 6A / ISO10423 certified materials

PPE offers a range of elastomer materials that have been third-party tested and certified to API 6A / ISO10423.  Our range of innovative sealing materials (including EnDura^®, Perlast^® and Perlast^® ICE grades) offers unique performance characteristics that have been developed to reduce downtime, improve production efficiency and increase reliability, by extending seal life in critical oilfield conditions. Test certificates can be downloaded for each material.

PPE's API 6A / ISO10423 certified elastomers can molded into infinite shapes and profiles to suit any application, including O-rings, X-rings, T-seals, chevron stacks, lip seals, wiper seals, spring seals and custom seals.
