Selection of Staining Agents for Te

17、sting StainResistance of Coatings5.1 The producer and the user shall select staining agentsfrom the reagents in Section 4. Selection of staining agentsshould depend on end use, such as wall, ceiling, horizontalsurface, or floor.5.2 In the absence of agreement between the producer andthe user, the su

18、ggested staining reagents for each intended useare indicated in Section 4 by V, H and L.5.3 It is not necessary that all finishes pass all tests.6. Test Specimen6.1 Test panels shall be of regular production finish.6.2 If regular production finished panels are not available,the producer and the user

19、 shall agree upon the followingvariables: face veneer or wood surface, filler or filler stain,primer coat, topcoat, and dry film thickness for each coatingmaterial.7. Panel Conditioning7.1 Before testing, panels must be aged for a time and by amethod agreed upon between the producer and the user.8.

20、Procedure8.1 Conduct the test with panel surfaces horizontal at roomtemperature unless a different temperature is specified.8.2 Place 0.5 mL (0.017 oz) of each staining agent on thefinish surface and allow to stand uncovered for 18 h (or a timeagreeable to the producer and the user) except for stain

21、ingagents 4.3 to 4.6. On these put a 25-mm (1-in.) square ofdouble-acid-washed quantitative filter paper. The purpose ofthe filter paper is to maintain a longer wet contact of volatilereagents with the surface of the finish.8.3 After 18 h exposure, or other time period agreed to bythe producer and t

22、he user, wash the surface with water, rinsewith ethanol (1 + 1), or other reagent as agreed upon betweenthe producer and user, and dry with a paper towel. Place thepanel in a vertical position with a diffuse light source and view(Note 1) from a distance of 0.6 to 0.9 m (2 to 3 ft). Examine thesurfac

23、e for graying, spotting, wrinkling, discoloration, or otherfilm defects and report.NOTE 1This method of viewing panels gives the best correlation ofstaining damage between laboratories. However, the following informa-tion should be noted: (1) When viewing panels across the grain at a lowangle that i

24、s being varied, many more stains will appear visible than wouldappear visible perpendicular to the surface. These additional stains aresuperficial stains only. (2) When viewing with and against the grain, thereappears to be an even greater number of superficial stains than wouldappear when viewing p

25、erpendicular to the surface or across the grain.9. Interpretation of Results9.1 Each product finish differs greatly in stain resistancerequirements. The key, in general, is that the resistance tostaining must be adequate for that finishs end use when firstused in place and throughout the expected li

26、fe span of thespecific product.9.2 The end use choice of resistance to staining should beagreed upon between the producer and the user.10.
