For hoses with a lining made of PTFE and derivatives, temperatures from -30 °C to +140 °C are permissible. Hose assemblies in accordance with this document are classified into four types, A - D, A - SD. B - D, B - SD.

 

 

This part of ISO 8873 specifies minimum requirements and test methods for spray-applied polyurethane rigid cellular plastic, used as a thermal insulation for both building, whether applied on a building site or in a prefabrication (manufacturing) facility, and non-building applications. The material is also known as in-situ thermal insulation. The spray-applied polyurethane rigid cellular plastic thermal insulation is not to be used when the continuous service temperature of the substrate is outside the range of -60 °C to +80 °C. The test methods used to determine the material properties provide a means of comparing different cellular plastic thermal insulations. They are intended for use in specifications, product evaluations and quality control. They are not intended to predict end-use product performance. Spray-applied polyurethane rigid cellular plastics are to be installed in accordance with the manufacturer's instructions and the requirements of ISO 8873-2. Applications, requirements for applications and limitations of use are included in ISO 8873-2. Persons using this document should be familiar with normal laboratory practice, if applicable. This document does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory requirements.

 

This document specifies two methods for the assessment of the surface resistance to different kinds of visible scratches. It relates to the rigid surfaces of all finished products, regardless of their material. It does not apply to finishes on leather and fabrics. Method A is suitable for all types of surface coatings and coverings except for melamine faced boards (according to EN 14322) and HPL (according to EN 438-1). It simulates measurable penetrating and/or deforming scratches. Method B is suitable for all types of surfaces. It simulates first visible traces (e.g. scratches, marks) that can also be a change in the gloss. The test is intended to be carried out on a part of finished furniture. It can, however, be carried out on test panels of the same material, finished in an identical manner to the finished product, and of a size sufficient to meet the requirements of the test. It is essential that the test be carried out on unused surfaces without any defects or damages.

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 specifies two methods for the determination of the chlorine content of homopolymers and copolymers of vinyl chloride, free from plasticizers or additives, namely: This document is also applicable as a reference method for the determination of chlorine content in other chlorine-containing polymers(such as chlorinated polyvinyl chloride, polyvinyl chloride, chlorinated polyethylene and Vinyl chloride-vinyl acetate) without plasticizers and additives.

 

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.
