1、Designation: F 1104 02Standard Test Method forPreparing Aircraft Cleaning Compounds, Liquid Type, WaterBase, for Storage Stability Testing1This standard is issued under the fixed designation F 1104; the number immediately following the designation indicates the year oforiginal adoption or, in the ca
2、se of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the stabil-ity in storage, of liquid, water-
3、base chemical cleaning com-pounds, used to clean the exterior surfaces of aircraft.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and

Referenced Documents2.1 U.S. Government Documents:Federal Specification PPP-P-704 Pails, Metal (Shipping,Steel, 1 through 12 Gallons)23. Summary of Test Method3.1 Storage stability is determined by evaluation of theeffect of time
5、, temperature, 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 env
6、ironment for a period 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 abil
7、ity to meetthe shelf-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 bat
8、chdelivered 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 material shall have previouslybeen tested and passed all other specification requirements forqualification or acceptance. The sample container sel
9、ected forthe test shall be kept sealed and unopened for the duration ofthe test. The sample container shall be durably and legiblymarked with the following minimum information:Storage Stability Test SampleSupplierFormula numberDate of packagingCold test periodHot test periodBatch/lot No.Test beganTe
