ISO 9588:2007规定了降低表面处理过程中可能出现的氢脆敏感性或敏感性程度的程序。 ISO 9588:2007中规定的钢铁热处理程序已被证明能有效降低氢脆敏感性。这些热处理程序在表面处理后，但在任何二次转化涂层操作之前使用。 ISO 9587中规定了制造后、表面精加工前的应力消除热处理程序。 ISO 9588:2007不适用于紧固件。

ISO 9588:2007 specifies procedures for reducing susceptibility, or degree of susceptibility, to hydrogen embrittlement that can arise in surface finishing processes. The heat-treatment procedures for iron or steel specified in ISO 9588:2007 have been shown to be effective in reducing the susceptibility to hydrogen embrittlement. These heat-treatment procedures are used after surface finishing, but prior to any secondary conversion-coating operation. Stress-relief heat-treatment procedures applied after fabrication, but prior to surface finishing, are specified in ISO 9587. ISO 9588:2007 does not apply to fasteners.
