Testing hub
Testing and standards, explained.
Which test answers which question, which standard sits behind it, and what a report should show. Original summaries, with the standard named so you can read the real thing.
Standards index
78 standards across physical testing, cure, ageing, fluids, classification, composition, oil and gas, water and food contact, and quality. Search and filter by area or polymer.
Open the index → ToolsPlanner, decoder and calculators
A test planner for your service conditions, an ASTM D2000 call-out decoder, and compression-set and volume-swell calculators.

Rapid gas decompression, oilfield qualification, drinking-water and food-contact approvals, and sour-gas ageing, each with a blank report template.

Oil and gas qualification
ISO 23936-2 and NORSOK M-710 are the usual references for elastomers in production service. API equipment standards reach the rubber through material and temperature classes.
Rapid gas decompression
Why seals blister when pressure drops fast, how the test is run and rated, and what a complete report shows.
Sour service
Hydrogen sulfide and amines attack rubbers in different ways. See how ageing in sour fluids is set up and judged.
Drinking water and food contact
NSF/ANSI 61, WRAS, KTW, FDA and others. Approvals belong to a formulation, a manufacturer and a facility.
Fluids, swell and ageing
How to test in oils, fuels and water, and how to read swell, hardness change and compression set after ageing.
