Summary of Test Method3.1 Storage stability is determined by evaluation of theeffect of time, temperature, and environmental conditions onthe cleaning compound. Samples used for testing are filledcontainers taken

6、from the manufacturers 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. Significa

7、nce 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-life requirements called up in specifications or con-tract documents. The subsequent testing req

8、uirements 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, filled container to the purchaser for use.This sample is normally a 1-gal can conforming to

9、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 kept sealed and unopened for the duration ofthe test. The sample container shall be durabl

Procedure6.1 Storage EnvironmentPlace the sample container in astorage area where a temperature of 10 to 27

11、C (50 to 80F) ismaintained at least 80 % of the total storage test time. Do notsubject the storage test sample to temperature over 32C (90F)or under 12C (10F) during the entire test. Maintain thesample container in a static condition not subject to vibration,rolling, inversion, or other movement. Mo

12、vement to thenecessary temperature-controlled area for cold- and hot-temperature testing is accepted, but accomplish such transferwith minimum (or no) disturbance of container contents.6.1.1 Cold-Temperature Storage EnvironmentSubject thesample container to a 15-day time interval at 8 6 2C (17 63F).

13、 Conduct this cold test interval during the period 90 to 120days after start of the storage stability test time.1This test method is under the jurisdiction of ASTM Committee F07 onAerospace and Aircraft and is the direct responsibility of Subcommittee F07.07 onQualification Testing of Aircraft Clean

17、C (71 to 80F). At the end of 48 h,remove the top of the container and examine the internalsurface for corrosion or sediment. Disregard discoloration ofthe interior surface of the container. Take samples of theproduct and test in accordance with the relevant specificationor contract requirements.7. P
