Question 2

How do I verify a lab's ISO 17025 accreditation scope?

Accepted Answer

ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. Where a lab has supplied its accredited scopes, TSTR.directory lists them. Always confirm the current scope certificate with the lab or the body that accredited it before you place an order.

Question 3

What is hydrogen embrittlement testing and when do I need it?

Accepted Answer

Hydrogen embrittlement testing measures how exposure to hydrogen degrades the mechanical properties of metals, causing sudden, delayed cracking under load. It is required for plated and fastened high-strength components, pressure-system parts, and hydrogen-fuel infrastructure. Common methods include ASTM F519 (notched specimen), ASTM F1459 (hydrogen gas), and ASTM G142.

Question 4

Can a buyer search TSTR.directory by specific standard and parameters?

Accepted Answer

Yes. TSTR.directory lets buyers filter laboratories by standard (e.g. ASTM F519) and, where a lab populates its scope, by parameters such as test method, pressure, and temperature. You can then request a quote from the listing.
