G189-1966 (R2003)

Preface

This is the first edition of CSA Standard G189 covering the requirements for sprayed aluminum and zinc coatings and the methods of testing for compliance.

Sprayed metal coatings are applied by projecting molten material in the form of a dispersed spray onto the surface to be coated and it is essential that the purchaser state the coating metal required and its nominal thickness.

The design of the article is most important in achieving maximum protection by metal spraying against corrosion (see Appendix C).

Scope
