This Part of BS 7371 specifies requirements for coatings applied by the electrolysis of solutions of zinc.<\/p>\n

\n

NOTE The coatings consist principally of zinc and can be lubricated to give controlled torque\/clamping force properties when required (see, for example, BS 7371-2).<\/p>\n<\/blockquote>\n

In addition to the requirements in this Part of BS 7371, the requirements in BS 7371-1 which are applicable to zinc electroplated coatings apply.<\/p>\n

This Part of BS 7371 also specifies requirements for:<\/p>\n

    \n
  1. \n

    the coating thickness;<\/p>\n<\/li>\n

  2. \n

    the type of conversion treatment or topcoat to be applied;<\/p>\n<\/li>\n

  3. \n

    quality assessment of the corrosion resistance of unused coated parts when subjected to neutral salt spray testing (for example BS EN ISO 9227); and<\/p>\n<\/li>\n

  4. \n

    an adhesion test.<\/p>\n<\/li>\n<\/ol>\n

    Zinc electroplated coatings covered by this Part of BS 7371 are for use on fasteners and accessories where the following apply:<\/p>\n

      \n
    1. \n

      A coating giving galvanic protection is required for ferrous fasteners.<\/p>\n<\/li>\n

    2. \n

      A substrate is required to improve the corrosion resistance of subsequent coatings on ferrous fasteners, e.g. organic.<\/p>\n<\/li>\n

    3. \n

      The risk of hydrogen embrittlement of high tensile steel fasteners is acceptable.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
