Report should include information such as time under load.

Deviations from the baseline zstm be reported as required by To perform the SLT procedure, an electro-mechanical testing machine equipped with the appropriate specimen grips and software capable of maintaining a constant force are necessary. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

We are happy to help! Mind you, if the only method you use is to mechanically clean you may want to clarify with your prime contractor. If cracks occur, an increased force is applied for the remainder of the test. C After baking, the specimens shall be dipped into any appropriate chromate conversion coating solution for minimum time that will produce an adherent and continuous coating as described in AMS-QQ-P Type II.

Hydrogen embrittlement ASTM F

ASTM F allows for various angles and fillets on the notch. Conduct the test by loading the samples to the asm value and then holding the load for the amount of time specified in ASTM F or until the material yields.

The sensitivity to hydrogen embrittlement shall be demonstrated for each lot of specimens as specified in 9. The details of testing in a service environment are found in Annex A5. The sensitivity to hydrogen embrittlement shall be demonstrated for each lot of specimens as specified in 9.

B The sole source of manufacture of Colcad known to the committee at this time is Columbia Chemical in Brunswick, Ohio, www. Extensive testing has shown that VAR steel may zstm used as an alternative to the air melted steel with no loss in sensitivity. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. Work with ashm to find the right equipment for your ASTM standard.

Self-loading notched round specimen bend fixture, Fig. Tensile strength of each specimen must be within 10 ksi of the average. Components with ultimate strengths higher than — ksi may not be represented by the baseline. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Brightener such as Colcad B or equivalent. Components with ultimate strengths higher than to ksi may not be represented by the baseline. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Although you may be cleaning production parts by blastingit is roundabout inferred that the notched test specimen is a capability test for your plating tank, not necessarily qualification for each and every different method of cleaning and plating.
