22、ured objects are: a) phosphorescent pigments; b) products made with phosphorescent pigments. DIN 67510-1:2009-11 6 4.1.2 Phosphorescent pigments Phosphorescent pigments can be measured in cuvettes with the following geometric dimensions: shape: round; diameter: 50 mm; depth: 5 mm. The material from
23、which the cuvette is made shall not affect the spectral characteristics of the radiation used for excitation or the radiation emitted by the phosphorescent pigment. When filling the cuvette, compact the phosphorescent pigment by tapping it repeatedly and smoothing it flat. DIN EN ISO 15528 applies w
24、hen taking samples of phosphorescent pigments for testing from one or more containers. Phosphorescent pigments can also be tested in transparent carriers such as printing ink binding agents or casting resin, or with a specified coated area, on a white, diffusely reflective surface. The conditions fo
25、r making the specimens shall be stated. 4.1.3 Phosphorescent products 4.1.3.1 Granules The requirements in 4.1.2 apply, but the cuvettes shall be 80 mm deep. When filling the cuvette, the granules shall be compacted so that individual particles do not move during the measurement. NOTE The larger the
26、 particles, the less reproducible the measurements. In the case of larger particles, it is therefore advisable to perform several measurements and use the average results. 4.1.3.2 Films, plates, enamels and signs 4.1.3.2.1 Sampling Samples are to be taken from each production batch. A distinction is
27、 made between the following cases: for batches of fewer than 50 units or less than 50 m2, one measurement shall be performed, for batches of fewer than 150 units or less than 150 m2, one measurement shall be made at the beginning and one at the end, for batches of more than 150 units or more than 15
28、0 m2, a measurement shall be made for every 200 units or 200 m2in addition to the measurements at the beginning and the end. 4.1.3.2.2 Backing on reverse side In order to measure the luminance of phosphorescent films it is essential that the phosphorescent layer has a white backing on the reverse si
29、de. However, because the pigment on these products is often not completely opaque and there are also applications without the white backing layer, films shall be provided with a backing of white, diffusely reflecting material with a reflectivity of 90 % for the measurement. For translucent materials
30、, a measurement shall also be carried out on a black background with a reflectivity 50 mm; d) uniformity within the area of the measured object to be evaluated: g2= Emin/Emax 1/1,1; e) excitation time: 5 min. The saturating excitation (see Annex B) may not have been reached. The sample shall have be
31、en kept in the dark so that its phosphorescence has decreased to 0,3 mcd/m2before excitation. 4.3 Measurement and excitation 4.3.1 Temperature The temperature shall be (22 3) C. 4.3.2 Illuminance measuring instrument The level and uniformity of illuminance shall be determined using an illuminance me
32、asuring instrument, which shall meet the following requirements: a) measurement range of at least 10 lx to 10 klx; b) diameter of the light aperture of the photometer head 80 % of the measured surface; c) other parameters according to class B as specified in DIN 5032-7. 4.3.3 Procedure To measure th
33、e level and distribution of illuminance in the plane of the evaluated area of the measured object, the light aperture of the photometer head shall be mounted in this plane. The illuminance shall be measured in the centre of the evaluated area of the measured object. The measurement of light decay sh
34、all begin within 10 s of the end of excitation. 4.4 Measurement of light decay 4.4.1 Luminance 4.4.1.1 General The luminance can be either measured directly or determined using an illuminance measurement. DIN 67510-1:2009-11 8 4.4.1.2 Measurement of luminance If luminance is to be measured directly,
35、 a luminance meter that meets the following requirements shall be used: a) measurement range of at least 105cd/m2to 10 cd/m2; b) a display with at least 3 digits; minimum value: 0,001 102, maximum value: 1,999 10; c) other parameters according to class A as specified in DIN 5032-7. The distance betw
36、een the luminance meter and the measured object, and the aperture angle of the luminance meter shall be chosen so that an area of the measured object with a diameter of 35 mm to 50 mm is evaluated. If the shape of the measured object means that different areas are measured, this shall be noted in th
37、e measurement record. 4.4.1.3 Determining the luminance by measuring illuminance 4.4.1.3.1 Principle The luminance of phosphorescent pigments and products can be determined using an illuminance measurement. The relationship between luminance and illuminance is defined by Equation (1): L = / p(1) whe
38、re L is the mean luminance of the measured object being examined; is the illuminance at a defined reference point on the light aperture of the photometer head (see DIN EN 13032-1); pis the projected solid angle which the evaluated area of the measured object makes with the centre of the light apertu
39、re of the photometer head. The projected solid angle pis calculated from Equation (2): p = (1 + (r/R)2)1 0(2) where 0 is the standard solid angle: 0= 1 sr; r is the distance of the light aperture of the photometer head from the measured object; R is the radius of the plane of the evaluated area of t
40、he measured object. 4.4.1.3.2 Measurement geometry The measurements shall be made using the following measurement geometry: a) diameter of the evaluated area of the measured object: 35 mm to 50 mm; b) distance between the measured object and the light aperture of the photometer head, equal to the di
41、ameter of the evaluated area. DIN 67510-1:2009-11 9 If the shape of the measured objects means that different areas are measured, this shall be noted in the measurement record. 4.4.1.3.3 Illuminance measuring instrument The illuminance measuring instrument shall meet the following requirements: a) m
42、easurement range when converting the display to luminance: 105cd/m2to 10 cd/m2; b) display with at least 3 digits; minimum value: 0,001 102; maximum value: 1,999 10; c) other parameters according to class A as specified in DIN 5032-7 with the exception of the cos evaluation (f2), for which there are
43、 no requirements. NOTE An analogue output and/or a computer interface (e.g. in accordance with DIN 66348-1) is recommended for recording purposes. 4.4.2 Effect of stray light Stray light entering the light aperture of the photometer head or the surface of the phosphorescent product shall be prevente
44、d as far as possible during the measurement, or its effects shall be corrected. NOTE Stray light occurs when artificial light or daylight is incident on the measured object and is reflected or transmitted by it, causing the luminance of the measured object to appear greater than that which is actual
45、ly produced by phosphorescence. Stray light can also occur when artificial light or daylight is incident on the light aperture of the photometer head used for the measurement. 4.4.3 Number of measured values Luminance readings in mcd/m2shall be taken at the end of excitation, after (2 0,1) min, (10
46、0,1) min, (30 0,2) min, (60 0,3) min and (120 0,5) min. 4.5 Determination of the decay time To determine the decay time, the luminance over time shall be measured as described in 4.4. If the value does not fall below (0,3 0,03) mcd/m2 after (120 1) min, the decay time can be determined using a suita
47、ble mathematical method (see Annex A). 4.6 Determination of the colour of phosphorescence To determine the colour of phosphorescence, colorimetric instruments using the trichromatic or spectral method (see DIN 5033-4 and DIN 5033-6) are used. The phosphorescent pigments or products are charged using
48、 equipment as described in 4.2, but in addition to Xe lamps, all other lamps whose spectral power distribution corresponds to the standard illuminant D65 can be used (see DIN 5033-7). The colour of phosphorescence is measured within 5 min of the end of excitation for the 2 standard observer. If a spectroradiometer is used to measure the colour of phosphorescence, a very fast or simultaneously measuring spectrometer should be used due to the changing colours o
