This document is applicable to the qualitative analysis of plastic materials in their original form by Raman spectroscopy. It describes procedures to determine the composition of unknown general plastics and multi-layer film plastics.
This document specifies test methods and requirements for the strength and durability of all types of extension elements and their components for all fields of application, except table extensions.
The tests consist of the application of loads, forces and velocities simulating normal functional use, as well as misuse, that can reasonably be expected to occur.
With the exception of the corrosion test in 6.4, the tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes.
The strength and durability tests only relate to the extension elements and the parts used for the attachment, e.g. screws.
The strength and durability tests are carried out in a test frame with specified properties. The test results can only be used as a guide to the performance of a piece of furniture.
The test results are only valid for the extension element tested. These results may be used to represent the performance of production models provided that the tested model is representative of the production model.
Ageing and influences of heat and humidity are not included.

ISO/CIE 11664-5:2016 specifies the method of calculating the coordinates of the CIE 1976 L*u*v* colour space including correlates of lightness, chroma, saturation and hue. It includes two methods for calculating Euclidean distances in this space to represent the relative perceived magnitude of colour differences. It also specifies the method of calculating the coordinates of the u',v' uniform chromaticity scale diagram.
ISO/CIE 11664-5:2016 is applicable to tristimulus values calculated using the colour-matching functions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. This part of ISO/CIE 11664 may be used for the specification of colour stimuli perceived as belonging to a reflecting or transmitting object, where a three-dimensional space more uniform than tristimulus space is required. This includes self-luminous displays, like cathode ray tubes, if they are being used to simulate reflecting or transmitting objects and if the stimuli are appropriately normalized. This part of ISO/CIE 11664, as a whole, does not apply to colour stimuli perceived as belonging to an area that appears to be emitting light as a primary light source or that appears to be specularly reflecting such light. Only the u',v' uniform chromaticity scale diagram defined in 4.1 and the correlates of hue and saturation defined in 4.3 apply to such colour stimuli.

This document specifies a thermogravimetric method for the determination of the main constituents of rubber compounds such as elastomer(s), carbon black and mineral filler. It establishes the “fingerprint” of the tested material. However, the result does not always correspond exactly to the theoretical formula of the rubber. This method applies to raw or compounded rubbers, vulcanized and unvulcanised, with or without extraction. This method applies to rubbers with hydrocarbon backbones (NR, BR, SBR, IIR, EPDM, ACM, AEM, etc.) used alone or as mixtures. For the mixtures, the polymer content corresponds to the total rubber, and it is not usually possible to identify individual polymers. This method applies to rubbers with halogenated hydrocarbon backbones (CR, CSM, FKM, CM, CO, ECO, etc.) or containing nitrogen (NBR, HNBR, NBR/PVC, etc.), as well as to their mixtures. However, these rubbers often form carbonaceous residues which interfere with the analysis. Application of an appropriate procedure minimizes these interferences. This method also applies to rubbers with a polysiloxane backbone (VMQ, etc.) and to rubbers not listed above.

This document specifies two methods for the measurement of the hydroxyl number of polyols used as polyurethane raw materials. It is necessary to know the hydroxyl content of polyols to properly formulate polyurethane systems. Method A is primarily applicable to readily esterified polyether polyols. It is also intended for polyols which have significant steric hindrance, such as those based on sugars. Method B is intended for polyether polyols, polymer polyols and amine-initiated polyols, but may give low results for sterically hindered polyols. Other polyols can be analysed by these methods if precautions are taken to verify applicability. These methods can be used for research and for quality control and specification purposes.
This document specifies test methods and requirements for the strength and durability of all types of extension elements and their components for all fields of application, except table extensions. With the exception of corrosion, ageing and the influence of heat and humidity are not included.

This document specifies a test method for assessing the peel strength of a thermoplastic elastomer (TPE) to a rigid substrate. It is mainly applicable to soft components in the Shore A hardness range. This standard specifies a test piece but not the injection moulding tool for its manufacture. Hence, different results could be obtained for test pieces produced using different injection moulding tools.

ISO 5771:2008 specifies the minimum requirements for rubber hoses used for transferring ammonia, in liquid or in gaseous form, at ambient temperatures from - 40 °C up to and including + 55 °C. It does not include specifications for end fittings, but is limited to the performance of the hoses and hose assemblies.
This document provides guidelines describing the adhesive bonding quality requirements suitable for use by adhesive user-
companies utilizing adhesive bonding as a means of fabrication. In particular, the guidelines define various approaches to meeting
quality requirements for fabrication and reporting procedures, both in workshops and on site. These guidelines aim to convey the
importance of maintaining quality standards in fabrication and reporting procedures, keeping records and thus enabling
documentation to provide the basis for risk evaluation of adhesively bonded structures in service and in use.
These guidelines have been prepared such that:
a) they are independent of the type of adhesively bonded structure;
b) they are independent of adhesive user-companies’ and suppliers’ product recommendations;
c) they define the quality requirements for adhesive bonding in terms of fabrication and reporting procedures, both in workshops and
on site;
d) they can be used as the basis for risk evaluation of adhesively bonded structures in service and in use;
e) they can be used as a basis for assessing a fabricator's capability to produce adhesively bonded structures fulfilling specified
quality requirements when they are detailed in one or more of the following:
— a contract between the parties involved;
— an application standard;
— a regulatory statement.
The guidelines contained within this document can be adopted in full or selectively chosen by the adhesive user to suit the structure
concerned. The guidelines provide a flexible framework for the control of adhesive bonding activities in the following cases.
Case 1
The provision of specific requirements for adhesive bonding in contracts that require the adhesive user to have a quality system other
than ISO 9001.
Case 2
The provision of specific requirements for adhesive bonding as guidance to an adhesive user developing a quality system.
Case 3
The provision of specific requirements for references in application standards that uses adhesive bonding as part of its requirements
or in a contract between relevant parties.
Case 4
The provision of a framework for fabrication and reporting procedures to a quality standard, suitable in particular as a basis for the risk
evaluation of adhesively bonded structures

This document specifies a method for determining the density of coating powders by liquid displacement in a measuring cylinder. The method is based on a determination of the mass and the volume of a test portion. It can be used for all types of coating powders.
NOTE If the powder does not swell in contact with the displacement liquid used and if the displacement liquid replaces the air between the powder particles, it can then be used and compared with the method described in ISO 8130-3.
