Laboratory local exhaust devices - Articulated extraction arms - Part 2: Commissioning and on-site testing
Scope: This document is applicable to test methods designed to be used at the place of installation of the articulated extraction arms (AEA), usually a laboratory and for various laboratory applications that require local extraction. They are used for commissioning after installation, for maintenance and for qualification purposes. For certain customer requirements additional or modified test methods can be necessary.
This document includes product functional performance referring to product standard detailed in EN 16589-1. Occupational health and safety assessments methods are not included in this document.
This document does not consider performance requirements for the extract air system associated with the AEA installation and therefore extract system performance is not part of the scope.
This document does not confirm or establish a capture zone of an AEA capture device only the functional extract capacity and mechanical functions of the AEA.

Biological durability of wood and wood-based products - Preparation of wood and wood-based material specimens before leaching testing
Scope: This document specifies a method for preparing treated wood test specimens prior leaching test to obtain water samples from treated wood which has been in conditions designed to simulate treated wood exposed out of ground contact (wood held in the storage yard after treatment and which has been in conditions designed to simulate outdoor, out of ground contact situations, use Class 3), or continuous contact with the ground or with water (use Class 4 or 5). This document is also applicable to untreated wood and modified wood.
NOTE 1 Test methods written in CEN/TC 38 include how to prepare specimens of wood and wood-based materials before leaching tests.
NOTE 2 EN 350 can be considered when using this document for testing untreated wood or modified wood, regarding reference wood species, number of test specimens etc.

Automotive fuels - Ethanol as a blending component for petrol - Requirements and test methods
Scope: This document specifies requirements and test methods for marketed and delivered ethanol to be used as an extender for automotive fuel for petrol engine vehicles in accordance with the requirements of EN 228 [5]. It is applicable to ethanol used for blending at all levels up to and including 85 % (V/V).
NOTE For the purposes of this document, the term “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, φ.
