Lovibond 341000 - ASTM Color
A set of three glass filters to check the AF650 Petroleum Oils Comparator in ASTM D1500 scale.
Conformance filters are assigned a nominal value and the company always endeavors to match this value as closely as possible. On occasion, because of the unique manner of the glass making process, it may not be possible to match the requested values exactly. The values achieved and the performance tolerances expected will, of course, always be reported.
