Air filters for general ventilation — Part 3: Determination of the gravimetric efficiency and the ai...
This document specifies the test equipment and the test methods used for measuring the gravimetric efficiency and resistance to air flow of air filter for general ventilation.
It is intended for use in conjunction with ISO 16890-1, ISO 16890-2 and ISO 16890-4.
The test method described in this document is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 …
Textiles — Synthetic filament yarns — Determination of dynamic thermal draw-force of partially orien...
This document specifies a method for the determination of the dynamic thermal draw-force of partially oriented synthetic filament yarns.
It is applicable to partially oriented polyester (PES), polyamide (PA) and polypropylene (PP) filament yarns, with a linear density less than 800 dtex.
Smart community infrastructure — Responsiveness assessment and maturity model
This document describes a maturity assessment model to evaluate the degree of responsiveness of the smart community infrastructure with different maturity levels.
This document provides the assessment domain (e.g. governance infrastructure, health infrastructure), categories (e.g. availability, affordability, safety and security, quality of service), and the criteria of maturity levels to assess…
Steel — Hardenability test by end quenching (Jominy test)
This document specifies a method for determining the hardenability of steel by end quenching (Jominy test) by using a test piece 25 mm in diameter and at least 100 mm long.
By agreement and for a defined field of application, the test described in this document can be replaced by the calculation of the Jominy curve according to an accepted mathematical model.

Steels — Micrographic determination of the apparent grain size
This document specifies micrographic methods of determining apparent ferritic or austenitic grain size in steels. It describes the methods of revealing grain boundaries and of estimating the mean grain size of specimens with unimodal size distribution. Although grains are three-dimensional in shape, the metallographic sectioning plane can cut through a grain at any point from a grain corner, to…
Acier — Essai de trempabilité par trempe en bout (essai Jominy)
Le présent document spécifie la méthode de détermination de la trempabilité de l'acier par trempe en bout (essai Jominy), à l'aide d'une éprouvette de 25 mm de diamètre et 100 mm de longueur minimum.
Par accord et pour un domaine d'application donné, l'essai décrit dans le présent document peut être remplacé par le calcul de la courbe Jominy selon un modèle mathématique…
