Do you have a source for liquid Saybolt and ASTM D1500 Color Standards? Follow
These liquid visual color standards can be used as an independent test to verify instrumental Saybolt and ASTM D1500 Color measurement performance over time for these two visual color scales used to evaluate oil, oil additive and petrochemical color quality.
Spectrum Quality Standards Inc.
Houston, TX 77084 USA
Spectrum Quality Standards is a small company that primarily makes GC and Physical Properties standards for the petroleum industry. Spectrum Quality also sells liquid Saybolt and ASTM D1500 color standards as defined in Appendix X1 of ASTM D6045.
You can buy a set if you want to check the entire range in each scale, or if your product purchase specification must be less than a maximum Saybolt or ASTM D1500 value, you could purchase an individual liquid standard at that level to monitor and document measurement performance over time.
