This part of ISO 5631 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. This part of ISO 5631 is not applicable to coloured papers or boards which incorporate fluorescent dyes or pigments. It may be used...
Applicable to all wood pulps and to most other types of pulp but not to pulps that contain added fluorescent materials.
1.1 This specification covers nails, spikes, staples, and other driven fasteners, as listed in Table 1. Note 1-Fastener ductility information is presented in Table 2 and dimensional information in Tables 3-67. 1.2 Fasteners described in this specification are driven by hand tool, power tool, or...
This standard specifies the test methods of the electronic circuit board for high-brightness LEDs (hereafter described as electronic circuit board). NOTE Reference documents to this standard are listed in Clause 11 Normative references and in the Bibliography.
This part of ISO 5631 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. This part of ISO 5631 is primarily intended for measuring the colour of paper and board to be used in the graphic arts...
This specification defines performance requirements for finished coatings of electrodeposited copper, bright or low gloss nickel, and bright and/or black chromium, bright or low gloss nickel, bright chromium and/or black for the decoration and protection of steel and/or...
1.1 This test method specifies the procedure for dry heat treatment of paper or board and the general procedure for testing the heat-treated materials. The purpose is to obtain, by an accelerated test, inferences about the aging qualities of the paper. 1.2 This test method is based on...
This Standard Practice deals only with simplified color indices applicable specifically to white colors. There are approximately 5000 distinguishable white colors. As with any other color, three numbers are necessary for the complete identification of any white. All the color and color difference...
This part of ISO 5631 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. This part of ISO 5631 is primarily intended for measuring the colour of paper and board to be used in the graphic arts...
This part of IEC 61189 specifies the test methods for thermal conductivity specific to printed circuit boards for high-brightness LEDs. The test applies to printed circuit boards for highbrightness LEDs with surface mounted LEDs or with device embedded LEDs in electronic control devices...
Summary The CIE Supplementary System of Photometry, which evaluates lights in terms of comparative brightness relationship at any level, is described. The system introduces the concept of equivalent luminance to describe brightness of a light or an object at any level including...
This document specifies the procedure to be used for determining the whiteness of papers and boards. The values obtained correspond to the visual appearance of white papers and boards with or without fluorescent whitening agents when they are viewed under the CIE D65 daylight standard illuminant....
