1、Designation: D 1308 02 (Reapproved 2007)Standard Test Method forEffect of Household Chemicals on Clear and PigmentedOrganic Finishes1This standard is issued under the fixed designation D 1308; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、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.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test meth
3、od covers determination of the effect ofhousehold chemicals on clear and pigmented organic finishes,resulting in any objectionable alteration in the surface, such asdiscoloration, change in gloss, blistering, softening, swelling,loss of adhesion, or special phenomena.1.2 The values stated in SI unit
4、s are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 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 prac
5、tices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Test Method3.1 Three test metho
6、ds, each of which is particularly appli-cable to individual reagents under study, are described asfollows:3.1.1 Spot Test, CoveredThe reagent is placed on the testsurface and immediately covered with a watch glass.3.1.2 Spot Test, OpenThe test surface is subjected directlyto the effect of substance,
7、 such as citrus fruit, oils, greases,beverages, etc.3.1.3 Immersion TestA suitably prepared panel is im-mersed in the test reagent.4. Significance and Use4.1 Resistance to various liquids used in the home is animportant characteristic of organic finishes. These test methodsprovide the means by which
8、 the relative performance ofcoating systems may be evaluated. It should be recognized thatcontinuous films are necessary for reliable results.5.

Allow thefinished panels to age 1 week at normal room conditions, about25C (77F) and 50 % relative humidity, before testing.7.2 Spot Test, CoveredConduct the test at 23 6 2C (73.56 3.5F) and 50 6 5 % relative humidity, or as agreed uponbetween the purchaser and the seller. Using a 5-mL pipetgrad
17、uated in 0.1 mL, pipet onto the horizontal panel 1 mL ofthe reagents listed in Section 6 and immediately cover with awatch glass.After an interval agreed upon by the purchaser andthe seller, wipe the spot clean and examine immediately foreffects as listed in 1.1. Frequently used intervals are 15 min
18、, 1h, and 16 h, or by agreement between the producer and theuser. If desired, allow the panel to recover for a specifiedperiod, and examine for return of original properties.7.3 Spot Test, OpenConduct the test at 23 6 2C (73.5 63.5F) and 50 6 5 % relative humidity, or as agreed uponbetween the purch
19、aser and the seller. Place a small portion ofthe reagent on a horizontal panel or surface, with the exceptionof fruit, as mentioned in 6.1.10. After a time interval, as agreedupon between the purchaser and the seller, wipe the spot cleanand examine immediately for effects as listed in 1.1. Frequentl
20、yused intervals are 15 min, 1 h, and 16 h, or by agreementbetween the producer and the user. If desired, allow the panelto recover for a specified period and examine for return oforiginal properties.7.4 ImmersionImmerse panels to a depth of 50 % in thespecified reagents (6.1.1, 6.1.2, 6.1.5, 6.1.6,
21、6.1.7, and 6.1.8)contained in beakers, at a temperature and length of timeagreed upon between the purchaser and the seller. Withdrawthe panels, wash with distilled water, and examine immediatelyfor any of the effects listed in 1.1. If desired, allow the panelsto recover for a specified period and ex
22、amine for return of theoriginal properties. In general, it will not be necessary to sealthe edges of the applied film. If the reagent effect is noted onlyaround the panel edges, the test should be repeated using asuitable edge sealer. When sealing of edges is required, theselection of the sealer sho
23、uld be a matter of agreement betweenthe purchaser and the seller.8. Report8.1 Report the following information:8.1.1 System and the testing method employed. The testconditions are an important factor in the results obtained and,therefore, should be defined in the report.8.1.2 The type of the effect,
24、 if any (see 1.1).9. Precision and Bias9.1 This test is designed to provide a working procedure forexamination of the effect of household chemicals on clear andpigmented organic finishes. The effects will be in terms ofappearance, which are nonquantitative. Numerical values maybe assigned if a ranki
25、ng scale is used. No information ispresented about either precision or bias of Test Method D 1308since test results are nonquantitative.10.
