Paper, board and printing inks – Printability – Laboratory test method for offset ink setting
This document describes a laboratory test method, using an IGT1-type or a prüfbau2-type printability tester, for the preparation of specimens to evaluate the absorption rate of an ink on a substrate in offset lithography by setting-off the printed surface to an unprinted surface.
This method describes testing with an amount of ink simulating either single colour or multi-colour printing. The…
Semiconductor devices - Discrete devices - Part 8: Field-effect transistors
IEC 60747-8:2010+A1:2021 gives standards for the following categories of field-effect transistors:
- type A: junction-gate type;
- type B: insulated-gate depletion (normally on) type;
- type C: insulated-gate enhancement (normally off) type.
The main changes with respect to the previous edition are listed below.
a) "Clause 3 Classification" was moved and added to Clause 1.

Textile floor coverings — State of the art and guidance on maintenance and cleaning
This document specifies guidelines for the development of specific textile floor covering maintenance and cleaning standards, procedures and criteria to reflect locally specific conditions. This document specifies the factors which are likely to impact the final results of textile floor covering cleaning, defining maintenance and cleaning terms to highlight differences. It establishes low-cost,…
Plastics — Poly(methyl methacrylate) double- and triple-skin sheets — Test methods
This document specifies the test methods for quality control of poly(methyl methacrylate) (PMMA) extruded double- and triple-skin flat sheets, obtained from colourless and coloured transparent, translucent and opaque grades of materials.
The minimum sheet width is 600 mm.
The main applications of these sheets are in building and agriculture (greenhouses).
