This Standard covers high efficiency oil/water separators intended for residential and commercial applications and specifies requirements for materials, physical characteristics, performance testing, and markings.

This standard covers both the analysis procedure and specifies the minimum acceptable volume of residual oil in the effluent of a high efficiency oil/water separator. The high efficiency oil/water separator is tested in a way that measures the volume of residual oil in the effluent of
the high efficiency oil/water separator. The volume of residual oil in the effluent is analyzed by gravimetric analysis.

The performance testing procedures of high efficiency oil/water separators developed in this standard harnessed select measurement procedures and analysis methodologies found in standards IGC 183, ASME A112.14.3, ASTM D6104, ASTM D7066, DIN 1999‐3, EPA Method 1664a, Resolution MEPC.107(49) and EN 858‐1.
