1、Designation: F 1105 09Standard Practice forPreparing Aircraft Cleaning Compounds, Liquid-Type,Temperature-Sensitive, or Solvent-Based, for StorageStability Testing1This standard is issued under the fixed designation F 1105; the number immediately following the designation indicates the year oforigin

2、al adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the determination of the stability instorage

3、 of liquid enzyme-based, terpene-based, and solvent-based chemical cleaning compounds used to clean the exteriorsurfaces of aircraft.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to addr

5、al Specification PPP-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 ma

6、nufacturers 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 Use

7、4.1 This practice 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 ared

8、etailed 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 FederalSpecifi

9、cation 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 durably and legiblym

Procedure6.1 Storage EnvironmentPlace the sample container in astorage area where a temperature of 10 to 27C (50 to 80F)

11、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. Movement to then

12、ecessary 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). Conduct this

13、cold test interval during the period 90 to 120days after start of the storage stability test time.1This practice is under the jurisdiction of ASTM Committee F07 on Aerospaceand Aircraft and is the direct responsibility of Subcommittee F07.07 on Qualifica-tion Testing of Aircraft Cleaning Materials.C

Conduct this hot test interval after 270 days of elapsedtest time but 60 days before the termination

16、 of the storage test.6.1.3 Completion of TestAfter 12 months storage testtime, carefully remove the sample container (if necessary),without agitation, rolling, or inversion, from the storage areaand place in a room, in a stable location for 48 6 1hatatemperature of 22 to 27C (71 to 80F). At the end

17、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. Keywords7.1 cold test perio
