Test method for the evaluation of permeability and filtration efficiency distribution of bag filter ...
This document specifies a measuring method for the distribution of thickness, area mass, gas permeability and collection efficiency in the filter medium, and applies to both woven and non-woven filter medium.
This document provides a method for sampling specimen (position, size and number) from the filter medium required to obtain its performance distribution accurately.
The purpose of this…
Surface chemical analysis — X-ray photoelectron spectroscopy — Method of intensity calibration for q...
This document specifies a procedure by which the intensity scale of an X-ray photoelectron spectrometer that employs a concentric hemispherical analyser can be calibrated using low-density poly(ethylene). This document is applicable to instruments using quartz-crystal-monochromated Al Kα X-rays and is suitable for all instrument geometries. The intensity calibration is only valid for the specific…
Information technology — Specification of digital rights management (DRM) technology for digital pub...
This document defines a technical solution for encrypting resources in digital publications (especially EPUB), effectively registering a device certificate to providers and securely delivering decryption keys to reading systems included in licenses tailored to specific devices. This technical solution uses the passphrase-based authentication method defined in ISO/IEC 23078-2 for reading systems…

This document defines a technical solution for encrypting resources in digital publications (especially EPUB) and for securely delivering decryption keys to reading systems, included in licenses tailored to specific users. It also defines a simple passphrase-based authentication method for reading systems to verify the license and access the encrypted resources of such digital publications.
Information technology — Specification of digital rights management (DRM) technology for digital pub...
This document describes three types of copyright protection technologies in use in the publishing industry:
— digital rights management (DRM) free protection, i.e. technologies which do not rely on content encryption but rather use content fingerprinting or watermarking, adequate for use cases where user convenience is the top priority;
— user key-based DRM protection, adequate where user…
Fire protection — Foam fire extinguishing systems — Part 6: Vehicle-mounted compressed air foam syst...
This document specifies requirements for compressed air foam systems (CAFS) in which foam concentrate and compressed air are continuously added to the water being discharged from the fire-fighting pump. This document is applicable to CAFS that can be permanently installed in fire-fighting vehicles, or that are transportable or mobile.
This document specifies requirements for CAFS which are used…
