33、ardner colour scale and USDA scale2)A.1 GeneralWhen testing rosin, it has historically been customary to use the USDA scale as defined in ASTM D509. Some users nevertheless prefer to use the Gardner scale as defined in ISO 4630-1. This annex describes a method of calculating the Gardner scale values

34、 which are equivalent to the rosin standards used in ASTM D509, taking into consideration the different path lengths used by the two methods.The visual method, specified in ISO 4630-1, of estimation of colour by the Gardner colour scale requires the test sample to be in a glass test tube, preferably

35、 of inside diameter 10,65 mm. This is usually approximated by a square cuvette with a path length of 10 mm. The USDA scale uses a 22,2 mm cube of material.A.2 ProcedureThe CIE x,y chromaticity coordinates and luminous transmittance Y corresponding to the 18 standards making up the Gardner colour sca

36、le have been taken from ISO 4630-1.The spectral-transmittance data for the 12 standards making up the USDA scale have been taken from ASTM D509. To find the equivalent values of transmittance for a 10 mm path length, these values were raised to the power of 10,0/22,2. This calculation assumes that B

37、eers law can be applied to the samples.Table A.1 shows the x,y and Y data for the Gardner colour scale and similar data calculated from the “corrected” USDA scale transmittance data. Note that the spectral-transmittance values for the three lightest USDA scale values, XA, XB and XC, are not given in

38、 ASTM D509. In order to be able to determine their Gardner equivalents, these spectral-transmittance values were measured using the actual glass standards specified in ASTM D509 and a path length of 22,2 mm.2) This annex applies to neat rosin and rosin derivatives.EN ISO 13632:2012 (E) DIN EN ISO 13
