DIN EN 15466-2:2009-10 EN 15466-2:2009 (E) 4 1 Scope This European Standard describes a method for determining the resistance against alkali of primers for cold and hot applied joint sealants. 2 Normative references The following referenced documents are indispensable for the application of this
18、European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

19、 Primers for cold and hot applied joint sealants 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 stan
20、dard atmosphere 23/50, class 2 (see EN ISO 291) 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 p
21、lates, each with one side painted with the primer, 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
22、any changes in the condition of the test liquids 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
23、 120 mm. 5.3 Preparation needle, (e. g. penetration 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. DIN EN 15466-2:2009-10 EN 15466-2:2009 (E) 5 NOTE Note-0,5% by mass/volume means 5 g of potass
24、ium hydroxide in 1000 ml solution. 5.7 Round rod, diameter (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 condi
25、tioning room at Standard atmosphere for at least 24 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 th
26、at it is uniformly distributed. Store the painted glass 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, th
27、at the amount of the painting in the dried condition 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
28、glass beaker one painted glass plate shall be placed 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
29、 glass plates The following criteria shall be inspected 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
30、. The painting on each glass plate shall be immediately 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 alon
31、g the scratched line; c) apparent difference in the 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. DIN EN 15466-2:2009-10 EN 15466-2:2009 (E) 6 6.6 Tes
32、ts on the immersed glass plates in dry condition After testing 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 preparati
33、on 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 hardness of the paintings between the
34、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. 7 Expression of results Report the primer as resistant against alkali, if all of the following criteria are fulfilled: a) the solution of pota
35、ssium hydroxide has no changes in colour and turbidity and 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 i
36、mmersed parts of the two glass plates; d) the painting in 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 t
37、hat the test was carried out in accordance with this European 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.
