Colour Standards

These standards are ideal for routine calibration of colour measuring instruments, verification of test data and ensuring good inter-laboratory or inter-instrument correlation. The range of liquid standards includes AOCS-Tintometer, ASTM, Gardner, Lovibond RYBN, Pt-Co and Saybolt Colour, the key colour scales applied to oils, fuels & chemicals. They are supplied with full traceability to the internationally recognised standards of  ISO 17025 & ISO Guide 34, accredited by UKAS (ASTM, Gardner & Saybolt Colour) or the ISO 9001 quality system (AOCS-Tintometer, Lovibond RYBN & Pt-Co Colour).
