Certified Color Reference Standards
Certified color reference standards are ideal for routine calibration, verification and ensuring good inter-laboratory or inter-instrument correlation. The range of liquid standards includes ASTM, Gardner, Pt-Co and Saybolt Color, the key color scales applied to oils, fuels, pharmaceuticals & chemicals.
Certified color reference standards are supplied with full traceability to internationally recognized standards, either UKAS to ISO 17025 (ASTM, Gardner & Saybolt Color) or the ISO 9001 quality system (Pt-Co color). Each standard comes in a 500 ml bottle with a 12-month guarantee of color stability and full certification including MSDS.
