MIL-PRF 87937D – Biodegradation Test – Surfactants

MIL-PRF 87937D is a performance test for electronic equipment cleaner surfactants that determines biodegradation by the Shake Flask Method.

The MIL-PRF 87937D establishes the requirements for biodegradable, water-dilutable, and environmentally safe cleaning compounds for use on aerospace equipment.  Biodegradability of the finished product is determined by the standard testing of 28 days by the Shake Flask Method.

Depending on the type of material that is defined by the method, the material must meet a percent biodegradation over the course of testing in order to meet testing requirements for biodegradability.

Additional Testing Information

Initial qualifications for a cleaning product to meet MIL-PRD 87937D include a product that has passed the qualification tests specified by the method and has been listed on the applicable Qualified Products List (QPL).

Unacceptable materials are cleaning compounds that contain any hazardous compounds as defined in 40 CFR 261, toxic pollutants in 40 CFR 301, or hazardous air pollutants in 40 CFR 63.
