ČSN EN 15416-1 This document specifies a method of determining the ability of adhesive bonds to resist long-term sustained load applied vertical to the glue lines. It is applicable to adhesives used in load-bearing timber structures. It is applicable for the following applications: a) for assessing the compliance of adhesives according to EN 15425 and EN 16254; b) for assessing the effect on the bond strength resulting from long-term sustained load at cyclic climate conditions. This method is intended primarily to obtain performance data for the classification of adhesives for load bearing timber structures according to their suitability for use in defined climatic environments. This method is not intended to provide data for structural design and does not necessarily represent the performance of the bonded member in service.

ČSN EN 15416-4 This document specifies a laboratory method of determining the open assembly time under referenced conditions in standard climate (20 ± 2) °C and (65 ± 5) % relative humidity (hereafter climate [20/65]). The method gives a result that cannot be applied to the safe manufacture of timber structures without taking into account the influence of factors such as timber density, moisture content, factory temperature and relative air humidity.

ČSN P CEN/TS 17812 This document outlines a method to measure the typical external noise emission produced when tyres of passenger car roll over a structured road marking. The result is a measure for the noise perceived in the surroundings of the road, hence not for interior noise in the car. This method can be used for three purposes: - determination of initial acoustic properties of a road marking, yielding a noise label for a given system; - testing of the acoustic conformity of a particular marking to the noise label determined during the determination of initial acoustic properties; - monitoring of the acoustic properties in the course of its lifetime. The test result allows the road owner to make an assessment of the risk of nuisance when s/he considers a particular road marking system for application on a road in a noise sensitive area, e.g. built up areas. The method is also applicable to measurements on milled rumble strips.

ČSN EN 12983-2+A1 This document specifies safety and performance requirements of domestic ceramic, glass ceramic cookware and glass lid for use on top of a cooking range or hob. This document envisages that oven top applications for ceramic utensils involve all or specific parts of the cooking operation, for example, the browning of meat, where the remainder of the cooking can be completed in an oven or on top of the cooking range. NOTE - Requirements for suitability for use with induction hobs are in the process of being compiled.
