Fire containment — Elements of building construction — Part 1: Ventilation ducts
This document specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts under standardized fire conditions. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This document is intended to be used in conjunction with ISO 834-1.
This document is not applicable to:
a) ducts whose fire…
Information security — Digital signatures with appendix — Part 4: Stateful hash-based mechanisms
This document specifies stateful digital signature mechanisms with appendix, where the level of security is determined by the security properties of the underlying hash function.
This document also provides requirements for implementing basic state management, which is needed for the secure deployment of the stateful schemes described in this document.

Facility management’s role in sustainability, resilience and adaptability
This document provides a broad societal context for facility management (FM) to inspire organizations that wish to:
— establish and improve a sustainable integrated FM system;
— embrace the wide-ranging and positive contribution that FM makes in managing the built environment;
— support the United Nations (UN) Sustainable Development Goals (SDGs).
This document provides a non-…
Intelligent transport systems — Roadside modules AP-DATEX data interface — Part 2: Generalised field...
Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS (C-ITS) environments, etc.
Field devices often need to exchange information with central devices (managers). Field devices can be quite complex necessitating the standardization of many data concepts…
