Fans — Determination of fan sound power levels under standardized laboratory conditions — Part 4: So...
ISO 13347-4:2004 applies to industrial fans as defined in ISO 5801 and ISO 13349. It is limited to the determination of airborne sound emission for the specified set-ups. Vibration is not measured, nor is the sensitivity of airborne sound emission to vibration effects determined.
The sizes of the fan, which can be tested in accordance with ISO 13347-4:2004, are limited only by the practical…
Plastiques — Méthodes d'exposition au rayonnement solaire — Partie 2: Exposition directe et exp...
L'ISO 877-2:2009 spécifie une méthode d'exposition directe des plastiques au rayonnement solaire et une méthode d'exposition des plastiques au rayonnement solaire sous filtre de verre (exposition derrière une vitre en verre). L'objectif consiste à évaluer les changements de propriété produits après des phases d'exposition spécifiées.

This document defines the requirements for the design, manufacturing, materials, welding, quality control, assembly, testing, documentation and process control of axial, ball, check, gate and plug valves for application in the oil and gas industries.
This document applies to ASME Class 150, 300, 600, 900, 1 500, and 2 500.
This document is a supplement to API 6D, 25th edition (2021), the…
This document specifies the suitable procedures and methods for the decommissioning of cyclotrons used by physics experiments and radioisotope production. For this purpose, computer simulation and real measurement of activated materials method can be employed.
Biodiversity – Process for designing and implementing biodiversity net gain in development projects
The Biodiversity Net Gain (BNG) standard will provide guidance on the design and delivery of gains for biodiversity through the lifecycle of a project.
The standard will set out the requirements for delivering BNG at each stage of a project, from preparation through design and implementation and into maintenance and monitoring. It will be applicable to all scales of development or conservation…
Corrosion of metals and alloys — Corrosion in artificial atmosphere — Accelerated corrosion test inv...
This document specifies an atmospheric accelerated test procedure in two closely related variants that contain intermittent salt exposure combined with dynamic humidity patterns: variant A at constant dew point and variant B at constant temperature. These variants are used in assessing the corrosion resistance of metals in environments where there is a significant influence of chloride ions,…
