This document specifies a reference method for the determination of volatile organic compound (VOC) emissions into indoor air from floor covering adhesives and products used for flooring installation. This method is applicable to determine volatile organic compounds, semi-volatile organic compounds, and volatile aldehydes. It is based on the use of a test chamber and subsequent analysis of an air sample for organic compounds by GC-MS respectively HPLC. The main purpose of the test procedure is to obtain relevant performance data for the classification of flooring adhesives and products used for the installation of floor coverings with respect to low VOC emissions during the use phase of the flooring.

This document describes a laboratory test method to determine the aerobic biodegradation of plastic materials exposed to seawater using accelerated conditions. Furthermore, this document describes the general requirements of the apparatus and the procedures for using this test method. The biodegradation is determined by measuring the oxygen demand in a closed respirometer or by measuring the CO2 evolved during mineralization of the plastic materials by microorganisms in the seawater. This test method is designed to give an early indication of the potential biodegradability of plastic materials in marine environment. In addition, for the purpose of promoting the development of biodegradable plastics, this document also provides a method for measuring the biomass components produced by metabolizing the test resin before it is completely mineralized to CO2, that enables to evaluate the potential biodegradability considered by carbon flow by the sum of the degree of biodegradation based on O2 and/or CO2 analysis and the degree of conversion to biomass in much shorter period of time than full mineralization. This method is not suitable to assess the degree of disintegration of plastic materials caused by abiotic factors like heat or UV radiation.

This document specifies requirements for almandite garnet abrasives, as supplied for blast-cleaning. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in the “new” condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127.

 

ISO 11126-10:2017 specifies requirements for almandite garnet abrasives, as supplied for blast-cleaning. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in ISO 11126-10:2017 apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127. NOTE Although ISO 11126-10:2017 has been developed specifically to meet requirements for preparation of steelwork, the properties specified are generally appropriate for use when preparing other material surfaces, or components, using blast- cleaning techniques. These techniques are described in ISO 8504-2.

 

This document specifies safety requirements and test methods for chairs and tables for general educational purposes in educational institutions including kindergarten, childcare institutions and early years education settings. It applies to furniture for use with laptop computers or portable devices, but not to special purpose workstations, e.g. laboratories, ranked seating and workshops. The chairs fulfilling the applicable requirements of this document are suitable for users weighing up to 110kg. The figures illustrate test principles only and cannot be used to carry out the tests. NOTE EN 1729-1 specifies functional dimensions and marking of chairs and tables for general educational institutions. Annex A (informative) gives a test method for determination of the displacement of chairs placed on tabletops.

They can also be used for vehicle/rail car loading and discharge where excessive vacuum does not occur. NOTE 2 Type F hoses can be used for plane delivery applications on vehicles that are also used for defuelling at high flow rates where type C hoses are not suitable. NOTE 3 Type E and F hoses can also be used for vehicle/rail car loading and discharge, for trailer to fueller transfer and for elevation platform supply (riser) to provide greater kink resistance.
