29、al Standard specifies a method of measuring the total and diffuse luminous reflectance characteristics of aluminium surfaces, using integrating-sphere instruments. The method described is also applicable to the measurement of specular reflectance (principal gloss value), specularity and diffuseness.

30、 The method is unsuitable for use with lighting reflectors. 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 references, the latest edition of the referenced document (i

32、 incidence, close to the normal surface of a test specimen. 4 Apparatus 4.1 General The reflectometer, suitable for measuring the reflectance of metallic surfaces, consists of a suitable light source, an integrating sphere and a photometer comprising a photo-electric cell with a signal multiplier an

33、d recording, indicating, or computing equipment. Figures 1 to 5 show the optical systems and geometry of typical instruments. The incident light beam is allowed to fall onto the specimen and is reflected into the sphere, the interior of which is white, where it is automatically integrated. The avera

34、ge light flux, as measured by the photometer, is a measure of the quantity of the reflected light. The spectral product of the light source, spectral filters, and spectral response of the light detector shall closely simulate the spectral product of the CIE source C (or D65) and the spectral luminou

35、s efficiency V() for photopic vision, in accordance with ISO 11664-2. DIN EN ISO 6719:2011-02 EN ISO 6719:2010 (E) 4 4.2 Geometrical specifications of the apparatus 4.2.1 Integrating sphere The interior of the sphere, white-coated and fitted with a device to permit measurement of reflectance, either

36、 including or excluding specular reflectance, serves to collect the reflected light flux. Any diameter of sphere is satisfactory, provided that the total port area does not exceed 5 % of the total internal surface. The internal surface shall be diffusing and of a highly reflective white for the whol

37、e of the visible spectrum. The entrance and specimen ports of the instrument shall be centred on the same great circle with an arc of more than 170 between their centres. The specimen port shall subtend 8 1 of arc in relation to the centre of the entrance port. The irradiating beam shall pass throug

38、h the centreline of the entrance and specimen ports. A photometer shall be positioned on the sphere at 90 0,5 from the entrance port. 4.3 Specular-included and specular-excluded determinations 4.3.1 Pivotable sphere In the pivotable-sphere type of instrument (Figures 1 to 4), the sphere can turn abo

39、ut a vertical axis passing through the specimen port, rotating 9 1 to provide for the measurements of specular-included or total reflectance (Q) and specular-excluded or diffuse reflectance (Qd). 4.3.2 Fixed sphere (Type 1) In the fixed-sphere Type 1 instrument, the specimen is held so that the inci

40、dent beam falls on it at an angle of 9 1 to the normal. A port, of the same dimensions as the entrance port, is provided in order to accept the specular reflection. Interchangeable caps are provided for this port, a black one to absorb the specular reflection for diffuse reflectance (Qd) measurement

41、s and one coated with the same material as the inside of the sphere for total reflectance (Q) measurements. 4.3.3 Fixed sphere (Type 2) In the fixed-sphere Type 2 instrument (see Figure 5), the sphere is fixed and only the specimen can be inclined. A wedge, as shown in Figure 5, designed to exclude

42、ambient light, and white-coated like the sphere interior, allows adjustment of the angle of the specimen surface. For measurement of diffuse reflectance (Qd), the specimen surface is adjusted to be perpendicular to the incident beam. For measurement of total reflectance (Q), the specimen surface is

43、inclined at 9 1 from the normal incident beam by insertion of the wedge. 4.4 Irradiation beam The light beam shall be substantially unidirectional with a maximum angle of any ray being less than 3 from the axis of the beam. It shall not be vignetted at either port. The incident light beam shall have

44、 a circular cross-section concentric with the specimen port and shall have an annulus of 1,3 0,1 subtended at the entrance port. On reflection from a first surface mirror, the specular-excluded beam shall be concentric with the centre of the port when the sphere is in the specular-excluded position.

45、 The mirror-reflected beam shall have a concentric circle with the port and shall have an annulus of 0,6 0,2 subtended at the level of the exit port. The size of the exit port shall be not more than 0,1 greater than that of the annulus. NOTE The dimensions of this beam can be most easily measured at

46、 a point beyond the sphere at a distance corresponding to the diameter of the integrating sphere, with no obstruction at either port. However, this will not ensure alignment when specularly reflected. DIN EN ISO 6719:2011-02 EN ISO 6719:2010 (E) 5 4.5 Housing A housing shall be provided to prevent a
