1、Designation: F2109 01 (Reapproved 2017)Standard Test Method toDetermine Color Change and Staining Caused by AircraftMaintenance Chemicals upon Aircraft Cabin Interior HardSurfaces1This standard is issued under the fixed designation F2109; the number immediately following the designation indicates th
2、e year oforiginal 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 test method covers the determination of color
3、change and staining from liquid solutions, such as cleaning ordisinfecting chemicals or both, on painted metallic surfacesand nonmetallic surfaces of materials being used inside theaircraft cabin. The effects upon the exposed specimens aremeasured with the AATCC Gray Scale for Color Change andAATCC
4、Gray Color Scale for Staining.NOTE 1This test method is applicable to any colored nonmetallic hardsurface in contact with liquids. The selected test specimens are chosenbecause these materials are present in the majority of aircraft cabininteriors.1.2 This standard does not purport to address all of
5、 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 determine the applica-bility of regulatory limitations prior to use.1.3 This international standard was developed in accor-dance with i

Interpretation of Results10.1 A numerical rating system is assigned by visuallycomparing the differences
29、 represented by the chip pairs of theoriginal and tested specimens. The scale runs from 1 to 5,progressing by half steps. A rating of 5 means that there is nodifference in color between the original material and the testedspecimen.10.1.1 Since any material deterioration is unacceptable,each rating o
30、ther than 5 on the AATCC Gray Scales for ColorChange and Staining is cause for rejection.10.2 Scratching or brittleness of exposed specimens shallalso be cause for rejection.11. Report11.1 Report the following data for each test performed:11.1.1 Name and type of maintenance chemical tested.11.1.2 Co
31、ncentration and diluent used.11.1.3 Type of surface material tested.11.1.4 Presence of visual color change and staining.9These materials should be washed before use since new unwashed wipers, incontact with the chemicals under test, may leave deposits on the surface of the testspecimens.F2109 01 (20
32、17)211.1.5 Presence of scratches or brittleness of the exposedspecimens.11.1.6 The acceptance or rejection of the candidate chemi-cal.12. Precision and Bias12.1 No statement is made about the precision of this testmethod since the result merely states whether there is confor-mance to the criteria fo
33、r success specified in the material orprocess specification of the chemical being tested, or both. Biascan not be obtained since there is no acceptable referencematerial.13.
