This glossary defines terms used in the pulp and paper industry relating to both visual and instrumental evaluations of appearance. This technical terminology includes such optical assessments such as brightness, whiteness, color, gloss, opacity, scattering, absorption, etc.
This method provides a means for determining the Effective Residual Ink Concentration (ERIC) in deinked pulp and paper made from recycled feedstock. The presence of ink influences the brightness and color of recycled paper. Trace amounts of residual ink can leave recycled...
IEC 62326-20:2016 specifies the properties of the printed circuit board (hereafter described as PCB) for high-brightness LEDs. Many aspects of the PCB for high-brightness LEDs are identical with those of ordinary PCBs, therefore, some aspects of this standard also describe general...
This method uses image analysis to determine the level of sub-visible contraries in pulp, recycled pulp, paper, and paperboard in terms of Equivalent Physical Diameter (EPD) of contraries within the EPD range of 8 micrometers to 160 micrometers, reported in parts per hundred as well as the...
This part of IEC 62326 specifies the properties of the printed circuit board (hereafter described as PCB) for high-brightness LEDs. Many aspects of the PCB for high-brightness LEDs are identical with those of ordinary PCBs, therefore, some aspects of this standard also describe...

Aim The purpose of the TC 1-80 work was to provide guidance to aid the successful implementation of the experimental procedures commonly used to measure spatial brightness. This was done through a review of the procedures and conditions under which these experiments have been carried out....
From the standpoint of use requirements, the determination of the machine direction of paper is essential where creasing is required, such as the folding of pages in books and pamphlets, or when scoring or creasing is performed as for cut-outs and folders. Determination of machine direction...
This part of ISO 19056 specifies procedures for the measurement of image brightness and uniformity for bright field light microscopy. These measurements for image brightness and uniformity are defined in image planes or intermediate image planes only, when these planes are...
This standard provides the following specifications for adding machine paper rolls: terminology; roll widths; roll length; paper substance and quality, thickness, finish, color, brightness, opacity, tearing and bursting strength; diameter of rolls; winding and cutting, core...
This specification describes minimum requirements to ensure performance of cut-sized white office papers, including bond, reprographic, and laser printer papers. Grades of brightness and standards for labeling are described. This specification covers virgin, recycled, and recycled content...
1.1 This specification describes minimum requirements to ensure performance of cut-sized white office papers, including bond, reprographic, and laser printer papers. Grades of brightness and standards for labeling are described. 1.2 This specification covers virgin, recycled, and recycled...
This method covers the determination of the 45-deg, 0-deg directional reflectance factor of nonfluorescent opaque specimens by means of filter photometers. To obtain similar results from spectrophotometers, see Method E308. NOTE 1-The values stated in inch-pound units are to be regarded as the...
This method (1-3) measures the resistance of paper to permeation of an aqueous penetrant and is a useful general purpose test for degree of sizing. It is applicable to most bleached, unbleached, and colored paper or boards which are surface sized and/or internally sized. It is not...
The scope of this recommended practices document is to - Define the concept of modulation frequencies for light-emitting diodes (LEDs) and discuss their applications to LED lighting. - Describe LED lighting applications in which modulation frequencies pose possible health risks to users. - Discuss...
