19、 indoor sports areas. 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
20、amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). ISO/CIE 10526, CIE standard illuminants for colorime
21、try. 3 Principle A collimated incident light beam is directed onto a test piece taken from the sports surface which is mounted in an integrating sphere and the total light reflected is detected by a photocell. 4 Apparatus (see Figure 1) 4.1Integrating sphere, of any diameter, having a matt white int
22、erior surface of similar reflectance to that of the reflectance standard and baffles. 4.2 Light entrance port and sample port, both centred on the same great circle of the sphere with at least 170 of arc between the centre of the light entrance port and the centre of the sample port. The axis of the
23、 irradiating beam shall pass through the centres of the light entrance and sample ports. The sample port shall not exceed 4 % of the internal reflecting area of the sphere and shall subtend an angle of 8 at the centre of the light entrance port. 4.3 Reflectance standard, designed as part of the inte
24、rior wall of the sphere adjacent to the sample port. The angle of rotation shall not exceed 10. 4.4Baffles, designed so that light cannot pass directly from the entrance port to the photocell or, in position 2 (see Figure 1), from the illuminated area of the sphere wall to the photocell. 4.5Mounting
