This document specifies test methods for the determination of the suitability of two component epoxy and two component polyurethane adhesives for glued-in steel rods in glued laminated timber (GLT) and glued solid timber (GST) according to EN 14080, cross laminated timber (CLT) according to EN 16351 and laminated veneer lumber (LVL) according to EN 14374.NOTE 1 The English term "glued-in rods" has been chosen as the established term instead of "bonded-in rods".It specifies performance requirements and the determination of characteristic bond strength values for such adhesives for the prefabrication under factory or factory-like conditions of joints between load-bearing timber products and steel rods only. This document does not cover the performance of adhesives for on-site gluing (except for factory-like conditions).NOTE 2 Factory like conditions provide shelter from direct weathering and dirt, prevent undue movement of the joints during curing of the adhesive and provide temperature and relative humidity conditions and control as in factory production environment.This document also covers glued-in rods in surface treated wood. It does not cover glued-in rods in modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. acetylated wood, heat treated wood, polymer impregnated wood and preservative treated wood.The joints are intended for load-bearing timber structures in service classes 1 and 2 according to EN 1995-1-1 which are loaded predominantly static or quasi static according to EN 1990 and EN 1991-1-1. The joints are intended for load-bearing timber structures which are not subjected to a prolonged exposure to temperatures over 60 °C.A design procedure for glued-in rods in glued structural timber products is given in an informative Annex A.NOTE 3 Several provisions of this document can apply to in situ repair and upgrading of existing timber structures including (cracked/fissured) solid wood beams. For adhesives for glued-in rods used in on-site repair or applications with solid timber additional provisions apply, e.g. related to rheology and site temperature conditions. Such provisions are not part of this document.

This European Standard specifies general requirements for the performance of procedures for the determination of the concentration of chemical agents in workplace atmospheres as required by the Chemical Agents Directive 98/24/EC. The requirements given apply to all measuring procedures, irrespective of the physical form of the chemical agent (gas, vapour, airborne particles), the sampling method and the analytical method used. This European Standard is applicable to all steps of a measuring procedure,measuring procedures with separate sampling and analysis steps, and direct-reading devices.

This document specifies a method for determination by melt filtration of solid contaminants content in a sample of recycled thermoplastic material, evaluating their number and, optionally, their size and substance (material).

This document describes procedures for the testing of migration of fluorescent whitening agents from paper and board intended to come into contact with foodstuffs. The method is based on liquid chromatography with fluorescence detection for quantification. The document is applicable to four different types of fluorescent whitening agents, diaminostilbene hexasulfonate, diaminostilbene tetrasulfonate, diaminostilbene disulfonate and distyrylbiphenyl.

This document specifies terms and definitions in the field of plastics related to any environmental aspects and provides a common vocabulary basis for:- biodegradability;- bio-based plastics;- carbon and environmental footprint;- plastics in natural environments;- recycling, e.g. mechanical and chemical recycling ;- design ;- waste management;- circular economy.This document aims to provide a comprehensive glossary which uses the applicable definitions providing when appropriate additional notes to make these definitions understandable without reference to other documents. Definitions are as far as possible adopted from existing standards but when the intention or definition is unclear additional context or definitions are updated or added.This standard aims to provide a comprehensive glossary which uses the applicable definitions providing when appropriate additional notes to make these definitions understandable without reference to other documents.As far as possible definitions are adapted from existing standards. But when the intention or definition isunclear additional context or definitions are updated or addedTerms which are also applicable to rubber will be indicated.

This document specifies safety requirements and test methods for mattresses including mattress bases and mattress toppers, used in children's cots, cribs and suspended baby beds, for domestic and non-domestic use. This document does not apply to mattresses for carry cots and pram bodies, inflatable mattresses, water mattresses and mattresses used for medical purposes.
