NACE TM0187

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
Reagents
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:

Volume
Modulus
Tensile strength
Hardness
Ultimate elongation
Mass
Compression set
Changes in appearance after exposure to the chosen test medium
