EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM F519 testing. This standard describes mechanical testing methods and defines acceptance criteria for coating and coating processes that can cause hydrogen embrittlement in steels.
Subsequent exposure to chemicals encountered in service environments such as liquids, cleaning operations or maintenance chemicals that come into contact with the coated/coated or bare surface of the steel may also be considered.
This test method is not designed to measure the relative susceptibility of different steels. The relative susceptibility of different materials to hydrogen embrittlement can be determined according to Test Method F1459 and Test Method F1624.
Extensive testing has shown that VAR 4340 steel can be used as an alternative to air-melted steel without loss of sensitivity.
VAR 4340 also meets the requirements of AMS 6415 and can be used by steel suppliers as an alternative to air-melt steel, as AMS 6415 does not specify a melting application.
Test procedures and acceptance requirements are specified for seven specimens with different sizes, geometries, and loading configurations.
Pass/Fail Requirements— Samples for coating/coating operations must meet or exceed 200 hours using continuous load testing (SLT) at the levels shown below. .
Quantitative, accelerated ( ≤ 24 hours) incremental step load (ISL) testing, as defined as an alternative to SLT, may be used if approved by the recognized engineering authority.
This test method is divided into two parts. The first part gives an overview of the requirements for hydrogen embrittlement testing. The second consists of appendices giving specific requirements for the various loading and sample configurations covered by this test method (see section 9.1 for a list of types) and details on test service environments.
Values in inch-pound units in the foot-pound-second (fps) system should be considered standard. Values in parentheses are mathematical conversions to non-standard SI units, provided for informational purposes only.
