What is ISO 787‑19 about?
ISO 787 discusses general test methods for paint pigments. ISO 787‑19 specifies a test method for determining the water-soluble nitrates in a sample of pigments by a spectrophotometric method using salicylic acid.
Note: ISO 787‑13 specifies a method for determining the water-soluble nitrates in a sample of pigments using Nessler`s method.
Who is ISO 787‑19 for?
ISO 787‑19 on test methods for pigments is useful for:
- Paint manufacturers
- Painters
- Quality control personnel
Why should you use ISO 787‑19?
The quality of paint pigments decides how vibrant a colour looks. ISO 787‑19 helps you to perform the salicylic acid test method by giving you detailed guidelines and requirements for the test. The salicylic acid test method described in ISO 787‑19 is free from the interference of ultraviolet radiation, unlike other methods. The salicylic acid test method is more accurate and cost-effective in determining water-soluble nitrates in pigment samples.
