ASTM-C1378 › Standard Test Method for Determination of Resistance to Staining
The following bibliographic material is provided to assist you with your purchasing decision:
This test method details the standard procedures for the determination of the resistance to staining of ceramic tile surfaces. A unsanded contrasting tile grout, black carbon lamp, waterproof black ink, washable ink, potassium permanganate solution, and methylene blue solutions are the staining agents required for this test method. Also, the following materials and apparatuses are needed: plain end glass test tubes; glass pipets; an oven; lintless, absorbent clothes or paper towels; distilled or deionized water; a light source; cleaning agents; hot water; weak commercial cleaning agent not containing abrasive; strong commercial cleaning agent containing abrasive; and suitable solvents such as hydrochloric acid and potassium hydroxide solution. The resistance to staining is determined by maintaining test solutions in contact with ceramic tile surfaces for a specified period of time. After exposure, the surface is cleaned in a defined manner, and the test specimens are inspected visually for change.
Scope
1.1 This test method covers a procedure for determining whether ceramic tiles and glass tiles are affected by prolonged exposure to staining agents.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Significance and Use
3.1 This test method is intended to determine the resistance to staining of tile surfaces. This test method is suitable for use in specifications, quality control, and research and development.
