Spécification géométrique des produits (GPS) — Filtrage — Partie 31: Filtres de profil robustes: Fil...
Le présent document spécifie des filtres de régression gaussiens robustes pour le filtrage des profils de surface. Il définit, en particulier, la manière de séparer les composantes latérales à grande échelle et à petite échelle des profils de surface avec des vallées et des collines saillantes.
Les concepts présentés pour les profils fermés sont applicables au cas du filtrage de circularité. Le…
Air intérieur — Partie 43: Méthode normalisée d'évaluation du taux d'abattement de champig...
Le présent document spécifie une méthode normalisée d'évaluation de la capacité des purificateurs d’air à réduire la concentration de champignons aéroportés et à nettoyer l’air dans l’environnement intérieur.
L’essai est applicable aux purificateurs d’air couramment utilisés dans des espaces ne comportant qu’une seule pièce.
Cranes and hoists — Selection of wire ropes, drums and sheaves
This document provides a proof of competence and criteria for the selection of steel wire ropes used in cranes as defined in ISO 4306-1.
The influence of the geometry of the rope drive, as well as drum and sheave geometry, are incorporated in the proof of competence.
This document does not apply to fibre ropes.
Indoor air — Part 43: Standard method for assessing the reduction rate of culturable airborne fungi ...
This document specifies a standard method to evaluate the capacity of air purifiers to reduce the concentration of airborne fungi and clean the air in the indoor environment.
The test is applicable to air purifiers which are commonly used in single room space.
This document specifies robust Gaussian regression filters for the filtration of surface profiles. It defines, in particular, how to separate large- and small-scale lateral components of surface profiles with protruding dales and hills.
The concept presented for closed profiles are applicable to the case of roundness filtering. Where appropriate, these concept can be extended to generalized…
This document defines a method for measuring the non-functional size of the software. It complements ISO/IEC 20926:2009, which defines a method for measuring the functional size of the software.
This document also describes the complementarity of functional and non-functional sizes, so that deriving the sizes from the functional and the non-functional requirements does not result in duplication…
Aircraft — Passenger doors interface requirements for connection of passenger boarding bridge or pas...
This document specifies minimum requirements for dimensions and unobstructed space around upper deck passenger doors on the outer skin of civil transport aircraft, applicable when these doors are designed to accept the connection of existing passenger boarding bridges or transfer vehicles.
This document is not applicable to existing models of civil transport aircraft, or derivative models with…
