1 Scope This Part of BS 7371 specifies requirements for organic coatings . The coatings consist principally of pigments and other additives bonded by resins and can be lubricated to give controlled torque/clamping force properties when required (see for example BS 7371: Part 2:1993). In addition to the requirements in this Part of BS 7371, the requirements in Part 1 of the standard which are applicable to organic coatings apply. This Part of BS 7371 also specifies requirements for the following:
a) four grades of coating;
b) colour;
c) quality assessment of the corrosion resistance of unused coated parts when subjected to neutral salt spray testing (see for example BS 7479:1991);
d) adhesion test.
