5、and environmental conditions onthe cleaning compound.Samples used for testing are filledcontainers taken from the manufacturers controlled productionformulation,packaged and delivered to the purchaser fornormal use.The sample container shall be subjected to thespecified storage environment for a per
6、iod of 12 months.Thetest shall be completed prior to 24 months from date ofpackaging.4.Significance and Use4.1 This test method determines the procedure to be used toensure the long term storage stability of aircraft cleaning andmaintenance products,in order to ensure their ability to meetthe shelf-
7、life requirements called up in specifications or con-tract documents.The subsequent testing requirements aredetailed in the specification or contract.5.Sampling5.1 The sample for storage stability testing shall be takenfrom a controlled production formula,packaged lot,or batchdelivered in a sealed,f
8、illed container to the purchaser for use.This sample is normally a 1 gal can conforming to FederalSpecification PPP-P-704.This material shall have previouslybeen tested and passed all other specification requirements forqualification or acceptance.The sample container selected forthe test shall be k
