Guidelines for biological filtration of secondary effluent for water reuse
This document provides guidance for deep purification of secondary effluent for non-potable reuse by using biological filtration systems in urban areas. It specifies general requirements, system selection, biological filtration system components, technical requirements of each component, water reuse applications and system design considerations.
This document is applicable to:
a) engineers that…

L'ISO 19702:2015 des exigences et formule des recommandations relatives aux systèmes de prélèvement à utiliser pour les essais au feu à petite et moyenne échelle, à la sélection des paramètres et l'utilisation de l'instrument IRTF lui-même, ainsi qu'à la collecte et l'utilisation des spectres d'étalonnage.
Hydraulic fluid power — Monitoring the level of particulate contamination of the fluid — Part 1: Gen...
ISO 21018-1:2008 specifies methods and techniques that are applicable to the monitoring of particulate contamination levels in hydraulic systems. It also describes the relative merits of various techniques so that the correct monitor for a given application can be selected.
The techniques described in ISO 21018-1:2008 are suitable for monitoring the general cleanliness level in hydraulic systems…
Cards and security devices for personal identification — Test methods — Part 6: Contactless proximit...
The ISO/IEC 10373 series defines test methods for characteristics of identification cards according to the definition given in ISO/IEC 7810. Each test method is cross‑referenced to one or more base standards, which can be ISO/IEC 7810 or one or more of the supplementary standards that define the information storage technologies employed in identification card applications.

Windows, doors and curtain walling — Impacted by windborne debris in windstorms — Test method and cl...
This document determines the resistance of windows (including skylights), doors, or curtain walling, to natural threats characterized by simulated destructive-windstorm events. The test method can also be used on windstorm protective systems for missile impact tests.
The test method determines the performance of windows, doors, or curtain walling, under conditions representative of events that…
Electrically propelled road vehicles — Electrical specifications and tests for voltage class B syste...
This document applies to voltage class B electric propulsion systems and connected auxiliary electric systems of electrically propelled road vehicles. It applies to electric circuits and components in these systems.
This document focuses on the characteristics at the DC voltage class B terminals of these components as specified in ISO 21498-1. It describes testing methods, test conditions and…
Language resource management — Semantic annotation framework (SemAF) — Part 12: Quantification
This proposed deliverable specifies an annotation scheme for semantic information relating to quantification in natural language. Quantification occurs whenever a predicate is applied to sets of arguments (rather than to single arguments) and gives rise to (among other things) questions of relative scope, distributivity, determinacy, and cardinality of collections of arguments. These issues make…
