10、tance to stains, published by the European Committee for Standardization (CEN). It is identical with ISO 10545-14:1995, including its Technical Corrigendum 1:1997, published by the International Organization for Standardization (ISO). It supersedes the test for staining in BS 6431-19:1984, which wil
11、l be withdrawn when Parts 1 to 16 of BS EN ISO 10545 have all been published. This Part of BS EN ISO 10545 was originally drafted by CEN/TC 67, Ceramic tiles, as part of EN 122, published in 1985, and confirmed in 1991. Subsequently the European Standard was revised by ISO as a Part of ISO 10545, wh
12、ich has now been approved by CEN as a Part of EN ISO 10545. The technical changes from the method described in BS 6431-19 are as follows. The staining agents applied to the tiles are pastes of green and red oxides in light oil, iodine in alcohol, and olive oil. After the staining agent has been in c
13、ontact with the tile for 24 h, it is cleaned successively with hot water, a weak cleaning agent and a strong cleaning agent that contains an abrasive. The tiles are then classified into five classes after examination. A British Standard does not purport to include all the necessary provisions of a c
14、ontract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN ISO title page, pages
15、 2 to 6 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

34、hanges. 4 Staining agents2) 4.1 Stains leaving a trace (pastes) 4.1.1 Green staining agent in light oil, in accordance with the specifications of Annex A. 4.1.2 Red staining agent in light oil (for green-coloured tiles only), in accordance with the specifications of Annex B. 4.2 Stains having chemic
35、al/oxidizing action 4.2.1 Iodine, 13 g/l solution in alcohol. 4.3 Stains, forming a film. 4.3.1 Olive oil, according to the definitions of the International Olive Oil Agreement (1979). 5 Cleaning 5.1 Cleaning agents 5.1.1 Hot water, at a temperature of (55 5) C. 5.1.2 Weak cleaning agent: a commerci
36、al agent, not containing abrasive, with a pH of 6,5 to 7,5. 5.1.3 Strong cleaning agent: a commercial cleaning agent, containing abrasive, with a pH of 9 to 10. The cleaning agents used shall not contain hydrofluoric acid or its compounds. 5.1.4 Suitable solvents 5.1.4.1 Hydrochloric acid, 3 %(V/V),
37、 prepared from concentrated HCl ( = 1,19 g/ml). 5.1.4.2 Potassium hydroxide, 200 g/l solution. 5.1.4.3 Acetone If other specific solvents are used, they shall be specified in the test report. 5.2 Cleaning procedures and apparatus 5.2.1 Procedure A Clean the test specimen with running hot water (5.1.
38、1) for 5 min, then wipe the surface with a damp cloth. 5.2.2 Procedure B Clean the test specimen manually with the weak cleaning agent (5.1.2), using a natural, non-abrasive sponge or a cloth, then rinse the surface with running water, and finally wipe it with a damp cloth. 5.2.3 Procedure C Clean t
39、he test specimen mechanically with the strong cleaning agent (5.1.3). Example of apparatus: Rotating brush, with hard bristles, having a 8 cm diameter, rotational frequency approximately 500 r/min. Tank for the cleaning agent, equipped with a suitable feeder, and connected to the brush. Carry out cl
40、eaning for 2 min, then rinse the surface with running water and finally wipe it with a damp cloth. 5.2.4 Procedure D Immerse the test specimen for 24 h in a suitable solvent (5.1.4), then thoroughly rinse the surface with running water and finally wipe it with a damp cloth. Cleaning is considered to
41、 be accomplished if any one of the solvents (5.1.4) removes the stain. 5.3 Auxiliary apparatus 5.3.1 Drying oven, capable of being operated at (110 5) C. 1) To be published. 2) The stains specified are only examples of basic groups. There are many other staining materials which may, upon agreement b
42、y the parties concerned, be tested using the procedure specified in this part of ISO 10545.

43、ying times, may be used provided that it has been determined that the same results are obtained. 6 Test specimens Five unused and undamaged test specimens shall be used, and they shall consist of whole tiles or cut tiles. However, a sufficient surface area is required to ensure separation of the sta
44、ins. If the tiles are too small, additional ones may be used. The test specimens shall be thoroughly cleaned with water and then dried in the oven (5.3.1) adjusted to (110 5) C until constant mass is reached, i.e. until the difference between two successive weighings is less than 0,1 g. The test spe
45、cimens shall then be cooled to room temperature in a desiccator. When it is agreed to test unglazed tiles after abrasion, the samples shall be prepared according to the procedure specified in ISO 10545-7, at 600 rev. 7 Procedure 7.1 Application of the staining agent Spread 3 or 4 drops of the paste
46、(4.1.1 or 4.1.2) on the surface. Allow 3 or 4 drops of each of the liquids (4.2.1 and 4.3.1) to cover separate areas of the test surface. Place a convex watch glass of diameter approximately 30 mm on the applied drops, in order to spread them to an approximately circular area. Leave staining agents
47、in place for 24 h. 7.2 Attempts to remove stains Subject the test specimens, treated according to 7.1, successively to the cleaning procedures described in 5.2 (procedures A, B, C and D). After each cleaning procedure, dry the test specimens in the oven (5.3.1) adjusted to (110 5) C and subject them
48、 to a visual examination. Examine the surface with the naked eye or with spectacles if usually worn, at a distance of 25 cm to 30 cm in daylight or artificial illumination of approximately 300 lx, but avoid direct sunlight. In the case of stains listed in 4.1, staining shall only be reported when th
49、e pigment is visible. If there is no visible effect, i.e. if the stain has been removed, record the cleanability class according to Figure 1; if the stain is not removed, proceed to the following cleaning procedure. 8 Classification of results In consequence of the procedure described in 7.1 and 7.2, ceramic surfaces are divided into five classes given in Figure 1. Record the result for each test specimen (unabraded and, if agreed, after abrasion for unglazed tiles) with each staining agent. Class 5
