For dated references, only
18、the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

19、ts Part 3: Determination of solids content and evaporation behaviour of volatiles 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 14188-4:2009 and the following apply. 3.1 standard atmosphere standard atmosphere 23/50, class 2 (see EN ISO 291
20、) 3.2 resistance against alkali resistance against alkali of a primer defined by the behaviour of the primer painted on a glass surface to insolubility, no changes in hardness and no peelings during immersion in an alkali solution 4 Principle Two glass plates, each with one side painted with the pri
21、mer, are immersed, one in a glass beaker filled with water and the other one in a glass beaker filled with a solution of potassium hydroxide in water. After conditioning in a test enclosure or conditioning room at standard atmosphere for 24 hours record any changes in the condition of the test liqui
22、ds and the painted glass plates. 5 Apparatus 5.1 Clear glass beaker, diameter approximately 120 mm, height approximately 200 mm, with an upper flat rim, no spout, and with a glass cover. 5.2 Glass plates, without scratches, dimensions approximately 90 mm 120 mm. 5.3 Preparation needle, (e. g. penetr
23、ation needle). 5.4 Paint brush 5.5 Water, distilled or totally deionised. 5.6 Solution of potassium hydroxide in water, 0,5 % by mass/volume, freshly prepared. BS EN 15466-2:2009EN 15466-2:2009 (E) 5 NOTE Note-0,5% by mass/volume means 5 g of potassium hydroxide in 1000 ml solution. 5.7 Round rod, d
24、iameter (10 2) mm, length (600 100) mm. 6 Procedure 6.1 Conditioning of primer and glass plates The primer shall be homogenized by shaking the container or by stirring with a suitable rod. The primer shall be conditioned in a test enclosure or conditioning room at Standard atmosphere for at least 24
25、 hours. The glass plates shall be cleaned, totally degreased, dried and conditioned at Standard atmosphere for at least 1 hour. 6.2 Painting of the glass plates One side of each of the two glass plates shall be painted all over with the primer so that it is uniformly distributed. Store the painted g
26、lass plates for a duration recommended by the manufacturer in a test enclosure or conditioning room at standard atmosphere. The quantity of the primer on a glass plate is calculated on the base of the solids content in accordance with EN 15466-3, that the amount of the painting in the dried conditio
27、n shall be between 15 g/m and 20 g/m. 6.3 Immersing of the glass plates One glass beaker shall be filled with water to a depth of 80 mm and the other glass beaker shall be filled with the solution of potassium hydroxide to a depth of 80 mm. In each glass beaker one painted glass plate shall be place
28、d vertically. Each glass beaker shall be covered with a glass cover. The glass beakers shall be allowed to stand for 24 h 15 min in a test enclosure or conditioning room at standard atmosphere. 6.4 Tests on the solution in glass beaker with immersed glass plates The following criteria shall be inspe
29、cted and reported: a) changes in colour and turbidity in both test liquids; b) presence of deposits on the bottom of both glass beakers. 6.5 Tests on the immersed glass plates in wet condition The glass plates shall be taken out of the glass beakers. The painting on each glass plate shall be immedia
30、tely scratched by pulling the preparation needle over the whole length of the glass plates. The following criteria shall be inspected and reported: a) presence of cloudiness and bubbles in both paintings; b) presence of peelings of the painting along the scratched line; c) apparent difference in the
31、 hardness of the paintings between the immersed and not-immersed parts of the glass plates; d) apparent difference in the hardness of the paintings between the immersed parts of both test liquids. BS EN 15466-2:2009EN 15466-2:2009 (E) 6 6.6 Tests on the immersed glass plates in dry condition After t
32、esting to 6.5, the glass plates shall be washed in water and allowed to dry for 5 h 15 min in a test enclosure or conditioning room at standard atmosphere. The painting on each glass plate shall be immediately scratched by pulling the preparation needle over the whole length of the glass plates. The
33、 following criteria shall be inspected and reported: a) presence of cloudiness and bubbles in both paintings; b) presence of peelings of the painting along the scratched line; c) apparent difference in the hardness of the paintings between the immersed and not-immersed parts of the glass plates; d)
34、apparent difference in the hardness of the paintings between the immersed parts of both test liquids. 7 Expression of results Report the primer as resistant against alkali, if all of the following criteria are fulfilled: a) the solution of potassium hydroxide has no changes in colour and turbidity a
35、nd no presence of deposits on the bottom of the glass beaker; b) the painting in wet condition has no presence of cloudiness and bubbles; c) the painting in wet condition has no apparent difference in the hardness of the paintings between the immersed parts of the two glass plates; d) the painting i
36、n dry condition has no peelings along the scratched line; e) the painting in dry condition has no apparent difference in the hardness between the immersed and not-immersed parts of the glass plates. 8 Test report The test report shall confirm that the test was carried out in accordance with this Eur
37、opean Standard and shall include the following information: a) product name and type; b) source of sample, batch number, date of manufacture and use by date; c) date of testing; d) test results; e) name of analyst and test laboratory.
