This document specifies an instrumental method for the routine determination of pH within the range pH 2 to pH 12 using a glass electrode in a 1:5 (volume fraction) suspension of soil, sludge and treated biowaste in water (pH in H2O), in 1 mol/l potassium chloride solution (pH in KCl) or in 0,01 mol/l calcium chloride solution (pH in CaCl2). This International Standard is applicable to all types of soil, sludge and biowaste, for example pretreated in accordance with ISO 11464 or EN 16179.

This European Standard describes the method to evaluate the performance of protective systems for electrical cable and busbar systems in order to maintain the circuit integrity under fire conditions to classify the protective system according to EN 13501 3 for the P classification. The test examines the behaviour of cable protection systems exposed to fire from outside. The tests specified in this standard are not aimed for assessing the performance of the fire protective system and the penetration seal for maintaining the requirements of the penetrated wall or ceiling (classification E / I). This method is very different to EN 50200 for the PH classification and also to IEC 60331 11, IEC 60331 21, IEC 60331 23, and IEC 60331 25, which are not designed for fire protective systems for electrical cable systems. This standard should be used in conjunction with EN 1363 1. The test results apply to fire protective systems for electrical cable systems rated for voltages up to 1 kV. The test

This European Standard specifies requirements and test methods for the performance of garments for protection against the effects of cool environments above −5 °C (see Annex C). These effects comprise not only low air temperatures, but also humidity and air velocity. Cold protective ensembles are excluded from this standard. The protective effects and requirements of footwear, gloves and separate head wear are excluded from the scope of this standard.

This document specifies the nomenclature for typical components of respiratory protective devices. It does not specify which or how many components are used and where they are located in the apparatus. The illustrations used are given as examples only for the identification of the different parts and the corresponding terms for facilitating the application. The terms and definitions used are given in EN ISO 16972:2020 and EN 135:1998. The terms are given in the three official CEN languages.
