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: four grades of coating; colour; quality assessment of the corrosion resistance of unused coated parts when subjected to neutral salt spray testing (see for example BS 7479 : 1991); adhesion test.
