This International Standard specifies a method of determining, on a statistical basis, the probability of the existence<\/p>\n
of hydrogen embrittlement or degradation in:<\/p>\n
a) a batch of barrel electroplated, autocatalytic plated, phosphated or chemically processed threaded articles;<\/p>\n
b) a batch of rack plated threaded articles or rods.<\/p>\n
This International Standard is applicable to threaded articles and rod made from steel with an actual tensile<\/p>\n
strength W 1 000 MPa (corresponding hardness values: 300 HV, 303 HB or 31 HRC) or to surface-hardened<\/p>\n
threaded articles or rods. It is not applicable to fasteners.<\/p>\n
The test method is carried out after hydrogen embrittlement relief heat treatment and may also be used for<\/p>\n
assessing differences in processing solutions, conditions and techniques.<\/p>\n
The test method has two main functions: a) when used with a statistical sampling plan it can be used for lot<\/p>\n
acceptance or rejection; b) it can be used as a control test to determine the effectiveness of the various processing<\/p>\n
steps including pre- and post-baking treatments to reduce the mobile hydrogen in the articles or rod.<\/p>\n
Although the test method is capable of indicating those articles that are embrittled to the extent defined in clause 2,<\/p>\n
it does not guarantee complete freedom from embrittlement.<\/p>\n
This International Standard does not relieve the plater, processor or manufacturer from imposing and monitoring<\/p>\n
suitable process control.<\/p>\n
NOTE 1 The use of inhibitors in acid pickling baths does not necessarily guarantee avoidance of hydrogen embrittlement.<\/p>\n
NOTE 2 Annex A provides guidance on sources of introduction of hydrogen into threaded articles.<\/p>\n","protected":false},"excerpt":{"rendered":"
