Mechanical vibration - Testing of mobile machinery in order to determine the vibration emission value

This document specifies the determination of whole-body and hand-arm vibration emissions at operator position(s) during testing of mobile machinery. The purpose of this document is to assist technical standardization committees responsible for specific types of machinery in preparing vibration test codes to ensure that such vibration test codes — are as homogeneous as possible with each individual test code having the same basic structure, — are in full accordance with basic standards on measurement of vibration emission, — reflect the latest technical knowledge of methods of determining the vibration emission from the specific family of machinery under consideration, — provide manufacturers with a standardized method for the determination and declaration of the vibration emission value(s) of their machinery, — enable the user of the machinery or the member of an inspection body to compare the vibration emission values of different machinery and to verify the vibration emission values provided by the manufacturer. This document provides requirements for the preparation of vibration test codes (C-type standards), including guidelines for the conditions under which the measurements shall be made (e.g. operating conditions). Information to be included in a typical vibration test code is summarized in Annex A. This document applies to sitting and standing positions. It is applicable to all mobile machinery producing periodic or random vibration with or without transients. This document contains sufficient guidance for designing an appropriate test for machinery for which no vibration test codes exist. It can also be used for the determination of vibration emission values of individual machines. This document is not applicable to rotational vibration and backrest vibration. This document does not present limits or recommended vibration values.

Biological durability of wood and wood-based products - Testing and classification of the durability against biological agents of wood and wood-based materials

This document gives guidance on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents. The methods can be applied to individual wood species and processed wood-based materials, including thermally and chemically modified, and water-repellent impregnated wood. Examples of wood-based materials are oriented strand boards (OSB), particle boards, fibre boards, laminated veneer lumber (LVL), and plywood. However, this document is not intended to give guidance on methods for determining and classifying the durability of wood products, coated wood, and wood polymer composites. Preservative-treated wood is not within the scope of this document, since requirements for the effectiveness of wood preservatives and durability requirements of wood treated with preservatives are regulated in several other European standards. However, this does not apply to modified wood, which is why it is included in the scope of this document. The wood-destroying agents considered in this document are: — wood-decay fungi (basidiomycete and soft-rot fungi); — beetles capable of attacking dry wood; — termites; — marine organisms capable of attacking wood in service. Data on the biological durability of the heartwood of selected wood species considered of economic importance in European countries are presented in Annex A (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability. NOTE Treatability, durability to disfiguring fungi, permeability to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex B (informative) for the classification of wood treatability with aqueous wood preservatives, Annex C (informative) for the classification of the permeability to water, and Annex D (informative) for the durability to disfiguring fungi.
