What is BS 3900-B5 - Liquid paints or coating powders about?
BS 3900-B5 discusses test methods for paints. The aim of the BS 3900-B series is to provide the best industrial practice to determine the soluble metal content in paint.
BS 3900-B5 describes methods for the preparation of acid extracts required as the test solutions for the determination of the “soluble” metal contents of paints and related products in liquid or powder form. The acid extracts are prepared in 0,07 mol/l hydrochloric acid, which is chosen as an approximation of the acid in the stomach.
Note: BS 3900-B5 is not applicable to dried or comminuted paint films.
Who is BS 3900-B5 Liquid paints or coating powders for?
BS 3900-B5 on liquid paints or coating powders is useful for:
- Liquid paint manufacturers
- Coating powder manufacturers
- Testing laboratories
- Quality control personnel
Why should you use BS 3900-B5 - Liquid paints or coating powders?
Paint production uses numerous chemicals to decorate, protect and prolong the life of natural and synthetic materials. BS 3900-B5 describes a laboratory method for acid extraction from paints. BS 3900-B5 covers the principle of the test method, reagents and materials, procedure, expression of result, and test report. This can help to determine the quantity of soluble metal present that aids in determining the characteristics of the liquid paints or coating powders.
