NACE TM0187 Standard Overview
Established in 1943 the ‘’National Association of Corrosion Engineers’’ (NACE) became the worldwide leader in evolving and improving the prevention of corrosion and control standards, education and certification for Oil & Gas Manufacture, Refining and Chemical Processing industries.
NACE TM0187 – ‘’Elastomeric materials in sour gas environments.’’
The standard establishes a test method that estimates the capacity of rubber materials to overcome static vulnerability to increased stresses and vapour-phase sour gas conditions. It is not intended to be a functional test or an immersion. It is, however, intended for testing standard O Rings or test samples of elastomeric vulcanites cut from standard sheets. This test method is not applicable to testing porous materials or cellular rubber.
NACE TM0187 states:
- Procedures for getting the test samples ready
- Test equipment
- Test procedures
- Reporting of test results
Additionally, it states:
- Test media
- Test conditions
- Conditions of temperature
- Exposure time
- Pressure for the exposure of test samples to the influence of a gaseous environment that contains H2S, CO2 (carbon dioxide), CH4 (methane), water vapour, hydrocarbon vapour
By testing, changes in mechanical and physical features the results can identify changes in:
- Tensile strength
- Ultimate elongation
- Compression set
- Changes in appearance after exposure to the chosen test medium
We offer a wide selection of elastomer material grades which have been tested and certified to NACE standards, they include Ethylene Propylene (EPDM), Fluoroelastomers (FKM/FPM), Perfluoroelastomers (FFKM), Tetrafluoroethylene Propylene (FEPM), Hydrogenated Nitrile (HNBR).
