1、Designation: C1378 04 (Reapproved 2014)Standard Test Method forDetermination of Resistance to Staining1This standard is issued under the fixed designation C1378; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi

2、sion. 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 is intended to determine the resistanceto staining of ceramic tile surfaces.1.2 The resistance to staining is

3、determined by maintainingtest solutions in contact with ceramic tile surfaces for aspecified period of time. After exposure, the surface is cleanedin a defined manner, and the test specimens are inspectedvisually for change.1.3 The values stated in SI units are to be regarded asstandard. No other un

4、its of measurement are included in thisstandard.1.4 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 determine the applica-bility of reg

5、ulatory limitations prior to use.2. Staining Agents2.1 Contrasting Grout, unsanded tile grout, applied as a neatpaste.2.2 Carbon Lamp Black.2.3 Waterproof Ink Black.2.4 Washable Ink.2.5 Potassium Permanganate Solution, 1 %, prepared from99 % KMnO4crystals, dissolve 1g of reagent into 100 mL ofdistil

6、led water.2.6 Methylene Blue Solution, 1 %.2.7 This test method may be used for exposing tile to anystaining agent deemed appropriate for the expected serviceconditions and may specify any reasonable combination oftime and temperature for the exposure period. Exposuresubstances, time, and temperatur

7、es should be selected so as toeither simulate service conditions, or accelerate staining that ispossible under expected service conditions, or bear some othermeaningful relation to expected service conditions.3. Apparatus3.1 Test Tubes, plain end glass test tubes with a diameter of20 mm and a length

8、 of 150 mm.3.2 Pipets, glass pipet with a volume of at least 50 mL withgradations in 1-mL increments.3.3 Oven, capable of maintaining a constant temperature of110 6 5C.3.4 Cloths, a supply of lintless, absorbent clothes or papertowels.3.5 Distilled or Deionized Water , for preparation of thesolution

11、one (technical grade).4. Samples4.1 Number of Test SpecimensOne defect-free testspecimen, which is representative of the entire surface, for eachtest solution is to be used. Test specimens shall be representa-tive of the sample, and where tiles have different colors ofdecorative effects, care should

12、 be taken to include all distinc-tive parts. More test specimens may be necessary to incorper-ate all surface features.4.2 Size of SpecimensThe original tile for testing shouldbe cut to 50- by 50-mm squares for testing with each cut piecelabeled according to the testing solution to be applied.4.3 Th

13、e sample surfaces should be thoroughly cleaned witha suitable solvent, such as acetone and completely dried beforetesting.1This test method is under the jurisdiction ofASTM Committee C21 on CeramicWhitewares and Related Productsand is the direct responsibility of SubcommitteeC21.06 on Ceramic Tile.C

15、 specimens can be glazed or unglazed tile. If thetiles are glazed, then the staining agent should be applied to theglazed surface.5. Procedure for Staining Agent Application5.1 Application of the Staining Agent:5.1.1 Dry the test specimens thoroughly at 110 6 5Cbefore testing and then cool the tile

16、to room temperature.5.1.2 The labeled test specimens are laid out on a table in awell-ventilated area.NOTE 1Precaution: This test method involves the use of chemicalsubstances. Proper precautions for the handling of these chemicals shouldbe taken, such as protective clothing and fume hoods.5.1.3 Tra

17、nsfer 5mL of the liquid staining agent described in2.3 2.6 to a test tube.5.1.4 Place the surface to be tested of the tile face down onthe open end of the test tube.5.1.5 While firmly holding the test tube and tile assemblytogether, invert the assembly so that the back of the tile isfacing the table

18、 and the closed end of the test tube is facing up.5.1.6 Carefully place the assembly on the table and leaveundisturbed for 24 h.5.1.7 For the dry staining agents described in 2.1 and 2.2,apply a generous amount of the staining agent with a cloth inthe center of the test specimen, being sure to leave

19、 someunexposed area for comparison. The grout described in 2.1should be mixed with enough distilled water to make a neatpaste before application. For light-colored tile, black groutshould be used, and for dark tile, white grout should be used.5.2 Removal of the Test Solutions :5.2.1 After 24 h of co

Report7.1 Make out a report with each of the staining agents used(see Fig. 1);7.2 Identify the tile being tested by type, size, and statewhether glazed or ung

27、lazed;7.3 State the test conditions, that is, type of staining agentsused, temperatures maintained during the test, and length ofexposure; and7.4 Report the results of the visual inspection for each tileby the simple statements “affected” or “not affected.”8.
