19、eland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This is one of a number of Parts of EN 1062 dealing with test methods for coating materials and coating systems for exterior masonry and concrete. It should be rea

20、d in conjunction with EN 1062-1. Depending on location, surface slope and direction, building materials are subjected to changes of temperature and humidity as well as to UV radiation in different succession, duration and intensity. Due to the variation of these influences and their combinations it

21、is reasonable to test the resistance to weather conditions of coatings for exterior masonry and concrete in order to confirm that they comply with particular requirements. The methods specified in this European Standard are suitable for conditioning before further testing and evaluation of the resis

22、tance of coatings to weather conditions. 1 Scope This European Standard specifies four methods for the conditioning of test specimens which have been prepared for testing the resistance to weather conditions of coating materials and coating systems for exterior masonry and concrete. The methods of c

23、onditioning specified make allowance of a wide range of weather conditions so that deviating methods of conditioning are required in exceptional cases only. Unless otherwise specified, for example in standards describing particular test methods, the method to be used should be agreed between the int

24、erested parties. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amen

25、dments or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Then subject the test specimens to the specified or agreed method(s) of conditioning described in clause 4. 4 Methods of conditioning 4.1 Elevated temperature Store the test specimens at a tempera

32、ture of 70 C for 7 days. Afterwards, condition the test specimens in the standard atmosphere as defined in EN 23270 (23 2) C and (50 5) % relative humidity for at least 24 h before carrying out further tests. NOTE This method allows conclusions regarding the change of physical, chemical and mechanic

33、al properties of chemically reacting resins (thermosetting resins) which occur in the course of time, especially at higher temperatures. It should be used particularly for coating materials containing thermosetting resins in the binder. 4.2 UV radiation and humidity Treat the test specimens in accor

34、dance with EN ISO 11507, lamp type 2 (UV-A), using a cycle of 4 h UV radiation and 4 h wetting without UV radiation for a total exposure duration of at least 1000 h before carrying out further tests. Maintain the black panel temperature during the irradiation (dry) phase at (60 3) C for a time perio

35、d of 4 h, unless otherwise agreed. Maintain the black panel temperature during the wetting phase at (50 3) C for a time period of 4 h, unless otherwise agreed. Afterwards, condition the test specimens in the standard atmosphere as defined in EN 23270 (23 2) C and (50 5) % relative humidity for at le

36、ast 24 h before carrying out further tests. NOTE This method allows conclusions regarding degradation of the surface by changes of mechanical properties of coatings due to UV radiation. It is particularly suitable for coatings which react to UV radiation. 4.3 Water storage Subject the test specimens

37、 to 3 cycles comprising the following conditions: 24 h storage in water (potable water) at (23 2) C; 24 h drying at (50 2) C. If the coatings are thermoplastic at 50 C, the test pieces shall be suspended and/or suitably placed in the oven, ensuring that they do not adhere to the parts of the oven an

38、d to each other. During weekends, or interruption for other reasons, store the test specimens in the standard atmosphere as defined in EN 23270 (23 2) C and (50 5) % relative humidity. Afterwards, condition the test specimens in the standard atmosphere as defined in EN 23270 (23 2) C and (50 5) % re

39、lative humidity for at least 24 h before carrying out further tests. 3EN 1062-11:2002 (E) NOTE This method allows conclusions regarding changes of properties of coatings which occur during water exposure due to dissolution of water-soluble constituents. It is of particular importance for water-borne

40、 coating materials and those containing water-soluble constituents or reacting with humidity. 4.4 Freeze-thaw stresses Subject the test specimens to 20 cycles as specified in prEN 13687:2001, method C, sub-clause b). Afterwards, condition the test specimens in the standard atmosphere as defined in E

41、N 23270 (23 2) C and (50 5) % relative humidity for at least 24 h before carrying out further tests. NOTE 1 This method allows conclusions regarding the behaviour of wet surfaces at temperatures below 0 C when ice crystals are formed in water-filled cavities. It is of particular importance for porou

42、s materials and those of high water absorption which are mainly applied to surfaces subjected to heavy water stresses. Examples are horizontal surfaces, pedestals and curbs continually subjected to splash water. NOTE 2 When using automatic equipment, the indicated times should be amended so that the

43、 specified temperatures are achieved, i.e. that finally the same test results will be obtained. 5 Assessment of test specimens after conditioning After conditioning in accordance with the agreed method(s) (clause 4), assess the test specimens for blistering, cracking, flaking or chalking, following

44、the methods described in ISO 4628-2, ISO 4628-4, ISO 4628-5 and prEN ISO 4628-7 respectively. When assessing chalking in accordance with prEN ISO 4628-7:2001, Table 1, use only ratings 0 (unchanged), 1 (very slight), 3 (moderate) and 5 (severe). 6 Test report The test report shall contain at least t

45、he following information: a) all details necessary to identify the test specimens; b) a reference to this part of EN 1062 (EN 1062-11); c) the method of conditioning used as described in clause 4; d) the result of the assessment of the conditioned test specimens (see clause 5); e) the total exposure

46、 time used; f) any deviation from the methods specified; g) the date of assessment. *) To be published. 4blankBS EN 1062-11:2002 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing British Standards.
