5、cificationPPP-P-704 Pails,Metal Shipping,Steel 1 through 12 Gallons23.Summary of Practice3.1 Storage stability is determined by evaluation of theeffect of time,temperature,and environmental conditions onthe cleaning compound.Samples used for testing are filledcontainers taken from the manufacturers
6、controlled productionformulation,packaged,and delivered to the purchaser fornormal use.3.2 The sample container shall be subjected to the specifiedstorage environment for a period of 12 months.The test shallbe completed prior to 24 months from date of packaging.4.Significance and Use4.1 This practic
7、e 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-life requirements called up in specifications or con-tract documents.The subsequent testing requirements aredetailed in the sp
8、ecification 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,filled container to the purchaser for use.This sample is normally a 1-gal can conforming to FederalSpecification PPP-P-704.This
9、 material shall have previouslybeen tested and passed all other specification requirements forqualification or acceptance.The sample container selected forthe test shall be kept sealed and unopened for the duration ofthe test.The sample container shall be durably and legiblymarked with the following
