This document describes a method in laboratory to assess the performance of ultraviolet germicidal irradiation (UVGI) devices which will be mounted in-duct in heating, ventilating and air-conditioning (HVAC) systems. The method includes the detailed requirements for test rig, microorganisms, procedures, data calculation and result report to determine the UV dose to model microorganisms by an UVGI…

This document specifies a test procedure, environment and instrumentation for measuring the exterior sound pressure levels from road vehicles under stationary conditions, providing a continuous measure of the sound pressure level over a range of engine speeds. This document applies only to road vehicles of categories L, M, and N equipped with internal combustion engines. Vehicles where an…

This document provides guidance to select a vibration generator that will be used to evaluate frequency responses of a test structure or to study how vibration grows/decreases along the structure. These structural dynamics tests can be carried out under field or laboratory conditions (see the ISO 7626 or ISO 10846[4][5][6][7] series). This document describes the selection procedure in terms of…

Le présent document spécifie une méthode de détermination par chromatographie en phase gazeuse des solvants présents dans les solutions de liant, les émulsions, les dispersions, ainsi que les peintures et vernis diluables à l'eau. Avec la fidélité indiquée à l'Article 13, il est possible de déterminer de manière quantitative les constituants d'une concentration supérieure à 0,02…

This document specifies reference buffer solutions for the calibration of pH measuring equipment.

This document specifies requirements for technical buffer solutions. These buffer solutions are preferably used for the calibration and adjustment of technical pH measuring equipment as well as pH measuring installations in laboratories. Measuring methods are given to determine pH values and buffer capacities of such buffer solutions based on pH reference buffer solutions in accordance with ISO…

Le présent document fournit des lignes directrices qui portent principalement sur l'évaluation de l'impact environnemental négatif des effluents du feu, y compris ceux dus à des incendies se produisant dans les locaux commerciaux et d'habitation, les sites commerciaux à l'air libre et les sites industriels et agricoles, ainsi que ceux impliquant les systèmes de transport…

This document gives guidelines whose primary focus is the assessment of the adverse environmental impact of fire effluents, including those from fires occurring in commercial and domestic premises, unenclosed commercial sites, industrial and agricultural sites, as well as those involving road, rail and maritime transport systems. It is not applicable to direct acute toxicity issues or wildland…

This document defines the primary space debris mitigation requirements applicable to all elements of unmanned systems launched into, or passing through, near-Earth space, including launch vehicle orbital stages, operating spacecraft and any objects released as part of normal operations. The requirements contained in this document are intended to reduce the growth of space debris by ensuring that…

This document provides general and specific guidance for the competency of assessors performing assessments in accordance with the ISO/IEC 330xx family of standards.
