This European Standard specifies a method for the determination of five Alternaria toxins in wheat, tomato juice and sunflower seed samples by liquid chromatography tandem mass spectrometry (LC-MS/MS). The method includes the analysis of Altenuene (ALT), Alternariol (AOH), Alternariol monomethyl ether (AME) in the range of 1 µg/kg to 100 µg/kg, and Tentoxin (TEN) in the range of 5 µg/kg to 500 µg/kg, and Tenuazonic acid (TEA) in the range of 10 µg/kg to 1000 µg/kg.

This document specifies a screening test method for determining the resistance of geotextiles and geotextile-related products to hydrolysis by exposing test specimens to water at elevated temperatures, followed by an evaluation of the changes in properties resulting from such exposure. It is intended as a means of establishing a minimum acceptable level of durability.The test is applicable to any geotextile and geotextile-related product susceptible to hydrolysis, in particular polyester and polyamide based materials, and in addition to the yarns from which these geotextiles are made.This method is not intended for determining the resistance of geotextiles to hydrolysis under highly acid or alkaline conditions.NOTE Performance tests to predict long-term lifetime or to compare products of different polymers or of similar polymers with differing structures can be based on the same method but with a wider range of temperatures and durations.

This document specifies the safety, construction and performance requirements for thermoelectric flame supervision devices, energized by a thermocouple intended for use with gas burners, gas appliances and similar use, hereafter referred to as “controls”.This document is applicable to controls with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 50 for use with one or more fuel gases in accordance with EN 437.This document is not applicable to:a) the thermocouple;b) controls which use auxiliary energy (e.g. electrical energy supplied externally).

This European Standard specifies the safety, design, construction, and performance requirements and testing for gas filters for burners and appliances burning one or more gaseous fuels.This European Standard is applicable to:— gas filters with declared maximum inlet pressure up to and including 600 kPa, of nominal connection size up to and including DN 250 for use with one or more fuel gases in accordance with EN 437:2009;— gas filters specified as pressure accessories as defined by EU Directive 2014/68/EU (see Annex F).NOTE 1 For pressure accessories, the requirements of EN 13611:2019, Annex F also apply.NOTE 2 Requirements for pressures above 500 kPa are considered in sub-clause 6.3.1 by referring to EN 13611:2019, Annexes F to H.This European Standard is not applicable to gas filters that are connected directly to mains pipe-work or to a container that maintains a standard distribution pressure.
