After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the

12、 Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2011, and conflicting national standards shall be with

BS EN 4593:2011EN 4593:2011 (E) 4 1 Scope This European Standard specifies the method of test for determining the solar absorptance of paints and varnishes. The test procedure determ

16、ines the amount of energy reflected by the material in the range of wavelengths at which there is energy from the sun hitting the Earths surface, and with the aid of a standard solar spectrum it allows a calculation to determine the solar absorptance which can then be used to determine the efficienc

17、y of solar heat reflecting paints. The procedure is applicable to products intended for use in aerospace applications. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated r

18、eferences, the latest edition of the referenced document (including any amendments) applies.

20、ng terms and definitions apply. 3.1 solar absorptance proportion of the energy emitted by the sun which hits the Earths surface which is absorbed by the material under test 4 Principle The reflectance of specimens, comprising of coated test panels is measured and summated over the range of solar ene

21、rgy which hits the Earths surface through two air masses, allows the calculation of solar absorptance. 5 Apparatus A recording spectrophotometer fitted with an integrating sphere which has the specular component included, a 10/diffuse measuring geometry and is capable of meeting the following requir

22、ements. Measuring range: 300 nm to 2 300 nm Wavelength accuracy: 5 nm Measuring accuracy: 2 % BS EN 4593:2011EN 4593:2011 (E) 5 Bandpass: 4 nm Replace (23 2) C and (50 5) % relative humidity with EN 23270, where applicable. 6 Specimens Take a representative sample of the product to be tested or of e

23、ach component in the case of a multi-coat system as described in EN ISO 15528. Examine and prepare each sample for testing as described in EN ISO 1513. The test panels shall be of a size suitable for the performance of the tests identified by this and the product standard. Coat the test panels with

24、the test product as specified by the product standard. Dry/cure the coating for the time and under the conditions specified in the product standard. The coating thickness, when determined using one of the non destructive procedures specified in EN ISO 2808 shall comply with the requirements of the p

25、roduct standard. Condition the test panels at a temperature and at a relative humidity of EN 23270 for a minimum of 16 h and a maximum of 72 h prior to testing. 7 Procedure Measure and record the reflectance spectrum using the reflectance grade barium sulphate as the reflectance standard on the spec

26、trophotometer in the wavelength range 300 nm to 2 300 nm. 8 Calculation Unless specified, use the solar spectral irradiance data (CIE publ No 85) through 2 air masses, 0,2 nm optical depth at 50 nm, 0,3 cm ozone and 2,0 cm precipitable water. Calculate the solar absorptance using the following equat

28、t for supplementary information to be provided by the product standard for the material under test. This information consists of: a) substrate type and method of preparation; b) method of application of the coating including, where applicable, the duration and conditions of drying/curing between coa

29、ts in the case of multi-coat systems; c) duration and conditions of drying/curing of the final coat before test; d) thickness of the dry coating or combination of coatings in micrometres; e) properties of the coating to be evaluated following exposure; f) number of air masses to employ for standard

30、solar spectrum. 10 Test report The test report shall contain at least the following information: a) all details necessary to identify the product tested; b) a reference to this test standard; c) a reference to the product standard; d) the items of supplementary information (see clause 9); e) the res

31、ults of the test work in terms of the stated requirements; f) any deviation from the test method specified; g) the date(s) of the test; h) name of the operator. 11 Designation EXAMPLE Description blockDETERMINATION OF SOLAR ABSORPTANCE Identity block EN 4593 Number of this standard This page deliber
