Phase quantitative analysis of residual quartz in silica bricks — X-ray diffraction method
This document specifies a method for the quantitative analysis of residual quartz (i.e. alpha-quartz) in silica bricks within the mass fraction range of 0,3Â % to 5,0Â %, by X-ray diffraction (XRD) using a Bragg-Brentano diffractometer. This document includes details of sample preparation and of preliminary establishment of a working curve using external standards.

Flexible and rigid cellular polymeric materials — Accelerated ageing tests
This document specifies laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity for flexible and rigid cellular polymeric materials.
Road vehicles — Advanced automatic collision notification (AACN) systems — Methodology for creating ...
This document outlines methodologies for creating and evaluating AACN algorithms, using suitable parameters, to predict the level of injury sustained by road users in a collision.
The injury prediction is used to facilitate emergency response after a collision occurs.
The methodology is based on onboard vehicle data and occupant-related information and applies to vehicle occupants and vulnerable…
Information technology — High efficiency coding and media delivery in heterogeneous environments — P...
This document specifies the Image File Format, an interoperable storage format for a single image, a collection of images, and sequences of images.
The format defined in this document is built on tools defined in ISO/IEC 14496-12 and enables the interchange, editing, and display of images, as well as the carriage of metadata associated with those images. The Image File Format defines structures…

Measurement of fluid flow in closed conduits — Velocity area method using Pitot static tubes
This document specifies a method for the determination in a closed conduit of the volume rate of flow of a regular flow
a)Â Â Â Â Â Â of a fluid of substantially constant density or corresponding to a Mach number not exceeding 0,25,
b)Â Â Â Â Â Â with substantially uniform stagnation temperature across the measuring cross-section,
c)Â Â Â Â Â Â Â running full in the conduit, and
d)      under steady flow…
Optics and optical instruments — Field procedures for testing geodetic and surveying instruments — P...
This document specifies field procedures to be adopted when determining and evaluating the precision (repeatability) of rotating lasers, the uncertainty of measurement results obtained by geodetic instruments and their ancillary equipment, particularly when used in building and surveying measurements for levelling tasks. Primarily, these tests are intended to be field verifications of the…
