Reagecon ASTM Colour Standard A7

Reagecon’s ASTM Colour Standard A7 can be used to calibrate, control, qualify or validate colour measurement instruments. This includes ASTM specified methods D1500, D6045 for petrochemical products and ISO 2049 and IP 196 for other liquids. This product is prepared gravimetrically on a weight/weight basis. Both solute and solvent are weighed on a balance calibrated by Reagecon engineers using OIML traceable weights. Reagecon holds ISO 17025 accreditation (A2LA Ref: 6739.02) for calibration of laboratory balances. The concentration of each standard is verified using a high performance top of the range calibrated spectrophotometer.
