Applicable to test pieces cut from products of cellular materials. Useful for two purposes: a) studying the structure of cellular products in connection with their physical properties and their method of manufacture and b) ensuring product quality (quality assurance). Describes principle, apparatus, test piece and conditions, procedure and calculation and expression of the results. Three figures deliver the details for testing.

This document classifies thermoplastic resin-based wood adhesives for non-structural applications into durability classes D1 to D4 based on the dry and wet strengths of bond-lines measured under specified conditions after various conditioning treatments.

For special applications, further tests that do not fall within the scope of this document can be applicable.

The adhesives specified in this document are suitable for the bonding of furniture and interior structures, panelling, doors, windows, stairs etc. made of wood or derived timber products.

This document does not specify the temperature resistance of bond-lines.

This document specifies tests for adhesives for wood and derived timber products for the assessment of their resistance to hot and cold water. It is used for the assessment of the strength of bonds with a thin bond-line. It does not apply to adhesives for structural use or to the manufacture of particleboards, fibreboards and plywood. It does not replace tests on finished products.

This document specifies the methods commonly available for separating adhesively bonded joints enabling repair and improving recycling. This document applies to adherends made of metallic and non-metallic inorganic material, plastics including both filler-containing and fibre-reinforced types, wood and wood-based materials, coated materials, adherends of natural and polymeric fibres as well as paper and cardboard.

This document specifies test procedures for the acquisition and presentation of multipoint data which demonstrate the behaviour of plastics under the following environments:

—   prolonged exposure to heat;

—   liquid chemicals;

—   environmental stress cracking under a constant tensile stress;

—   artificial weathering. The tests are listed in order of increasing severity of the environment. By testing under the least severe environments first, it is possible to make informed judgements regarding whether tests under more severe conditions are worthwhile.

This document specifies the methods of test for determination of the properties of high-pressure decorative laminates as defined in Clause 3. These methods are primarily intended for testing the sheets specified in EN 438-3, EN 438-4, EN 438-5, EN 438-6, EN 438-8, and EN 438-9. The precision of the test methods, specified in this document, is not known because inter-laboratory data are not yet available. When inter-laboratory data will be obtained, precision statements will be added to the test method at the following revision. For those test methods having an end point determination based on subjective judgement, it is not meaningful to make a statement of precision.

This document specifies the methods of preparation of test specimens and the test methods to be used for determining the properties of ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials. It establishes general principles for handling test materials and for conditioning both the test materials before moulding and the specimens before testing.

This document specifies procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. Properties and test methods which are suitable and necessary to characterize PE-UHMW moulding and extrusion materials are established.

The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 21304-1. This document specifies the-materials with MFR less than 0,1 g/10 min at 190 °C /21,6 kg based on ISO 17855-1.

The methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this document are used in order to obtain reproducible and comparable test results. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

This document outlines methods for measuring the strain distribution for randomly oriented chopped strand- or fibre-reinforced plastic composites, based upon the general principles given in ISO 527-4. The methods are used to statistically evaluate the inherent variation of strain-based properties. The main purpose of this document compared to existing standards is to evaluate the strain distribution due to the random orientation of chopped fibres, while ISO 527-4 is sufficient for evaluating only the bulk elastic modulus.

This standard provides two methods for evaluating an inherent strain distribution of the material, Method A as using DIC analysis system and Method B as using several strain gauges with a short gauge length.

The methods are suitable for use with fibre-reinforced thermosetting and thermoplastic composites incorporating discontinuous or chopped reinforcements such as mats, chopped strands or tapes, long-fibre injection or combination of such reinforcements. The methods are not normally suitable for continuous fibre-reinforced materials which generate homogeneous strain distribution on the surface of the test specimen.
