What is BS 3900-D9 - Optical tests on paint films about?
BS 3900- D9 discusses test methods for paints. The aim of the BS 3900-D series is to provide the best industrial practice to ensure the reliability of paints.
BS 3900- D9 describes the method for determining the colour coordinated of paint films. The method is only applicable to paint films that appear to be uniformly of one colour, i.e monochromatic when examined with normal vision. Paint films that do not completely hide a non-transparent substrate represent an opaque system and may be measured by using the procedure described in BS 3900-D9.
Note: Luminescent paint films, transparent paint films and translucent paint films (for example for displays or lamp glass), retroreflecting paint films (for example for traffic signs), and metallic paint films are outside the scope of BS 3900-D9.
Who is BS 3900-D9 - Optical tests on paint films for?
BS 3900-D9 on determination of colour and colour difference is useful for:
- Paint manufacturers
- Testing laboratories
- Quality control personnel
Why should you use BS 3900-D9 - Optical tests on paint films?
The paint opacity is also greatly determined by the dispersion status of the pigment particles in the liquid medium. Complete dispersion of the pigments is required for optimum colour strength, good opacity as well as improved mechanical characteristics of the coating film.
BS 3900-D9 provides a method for determining the colour and the colour difference of the paint. This helps in determining the colour deviation in the production of paints that can aid in controlling or regulating the process. BS 3900-D9 can help in determining the color changes that are caused by weathering, chemical or physical influences. This helps in determining the quality of your paints.
If you are a manufacturer, BS 3900-D9 can ensure that your product’s colour quality is maintained.
