This part of the EN 20 series specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infection by Lyctus brunneus (Stephens) when the product is applied as a surface treatment to wood.This method is applicable to:- water-insoluble chemicals which are being studied as active insecticides; or- organic formulsation, as supplied or as prepared in the laboratory by dilution of concentrates; or- organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; or- water-soluble materials, for example salts.NOTE This method can be used in conjuction with ageing procedures, which do not remove the added nutrient.

This part of the EN 20 series specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infection by Lyctus brunneus (Stephens) in wood which has been treated previously by full impregantion.This method is applicable to:- water-insoluble chemicals which are being studied as active insecticides; or- organic formulsation, as supplied or as prepared in the laboratory by dilution of concentrates.This method is applicable to water-based preservatives.NOTE This method can be used in conjuction with ageing procedures, which do not remove the added nutrient.

This document specifies a method for the determination of the toxic values of a wood preservative against the Reticulitermes species of European termites.This method is applicable to:- water-insoluble chemicals which are being studied as active insecticides;- organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and- water-soluble materials, for example salts.NOTE This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.

This document specifies a method for the determination of the curative action of a wood preservative against infestation by Anobium punctatum (De Geer) when the product is applied as a surface treatment to wood.This method is applicable to any surface-applied treatment that is intended to prevent emergence of adult beetles but not intended to kill larvae in infested timber.NOTE 1 This method can be used in conjunction with an ageing procedure, for example EN 73.NOTE 2 Products intended to kill larvae can be tested by the method described in EN 48.

A method for measuring the insulation performance of building elements such as exterior walls, floors, ceilings, etc. (hereinafter referred to collectively as walls) in the field is described by the use of the temperature distribution in the wall obtained by inserting a temperature sensor in a small diameter borehole in the wall. The measurement method is divided into a quantitative method which measures the thermal resistance with a heat flow measurement, and a qualitative method without heat flow measurement. The methods elaborated in this document are particularly suited to testing the insulation layer in walls. It describes a screening test that requires the drilling of a small diameter borehole through the walls which include an insulation layer. The method is applicable to plane building components with a light heat capacity, such as those in frame structure dwellings. The measured results give the insulation performance at the local measurement points rather than that of the whole panel including thermal bridges such as studs.

This European Standard covers hinged and pivoted doors, doorsets and door assemblies with glass basedleaves. Throughout this document the term “doorset” will be used to cover doors, doorsets and doorassemblies. It prescribes the methodology for extending the application of test results obtained from fireresistance test(s) conducted in accordance with EN 1634-1 and/or EN 1634-3 and/or EN 1191.Subject to the completion of the appropriate test or tests, the extended application may cover all or someof the following examples:integrity (E), integrity & radiation (EW) or integrity & insulation (EI1 or EI2) classification;ambient temperature smoke control (Sa) and medium temperature smoke control (S200)classifications;ability to close and durability of self-closing (C0 – C5);glazed elements;side, transom or over panels;items of building hardware;decorative and protective finishes;intumescent seals and non-intumescent (e.g. smoke, draught or acoustic) seals;alternative supporting construction(s).This standard does not cover horizontal doorsets and windows.

This document specifies the structural performance requirements of curtain walling under wind load, both its fixed and openable parts, under positive and negative static air pressure.This document applies to any curtain walling product as defined in EN 13830.

This document lists visual strength grades, species and sources of timber, and specifies the strength classes to which they are assigned. The assignments listed are for strength classes documented in EN 338. The assignments apply to timber that has not been previously strength graded in a way that introduces a bias on the population of timber to be graded, as compared to ungraded material.Species/grades or species combination/grades are assigned to strength classes in accordance with EN 14081-1 and supporting standards.This document contains a list of assignments but is not intended to be exhaustive.NOTE 1 Timber graded by machine to EN 14081 is graded directly to the strength classes and marked accordingly. Machine grading is therefore not referenced in this document.NOTE 2 For combinations of species and visual grades which meet the requirements of EN 14081 but are not listed in this document, the assignment to strength classes is made according to EN 384.

This document provides product category rules (c-PCR), that are complementary to EN 15804:2012+A2:2019, for Type III environmental declarations for gypsum-based products for the construction industry.This document is intended to be used in conjunction with EN 15804:2012+A2:2019.

Firebrand showers are a main driver of fire spread in large outdoor fires but there is no accepted internationally harmonized device to generate firebrand showers. An ISO standard firebrand generator is described that is a stand-alone device. In this document, the rules and requirements concerning the construction and operation of the ISO standard firebrand generator is described. This standard applies to all firebrand generators.
