This document specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments.

Test conditions are only given for open cellular latex, both open- and closed-cell polyurethane foams, and closed-cell polyolefin foams. Conditions for other materials will be added as required.

The effect of the ageing procedures on any of the physical properties of the material can be examined, but those normally tested are either the elongation and tensile properties, or the compression or indentation hardness properties.

These tests do not necessarily correlate either with service behaviour or with ageing by exposure to light.

If desired, the ageing conditions contained in this document can be applied to composite structures containing any of the above types of cellular material. This can be helpful in the investigation of possible interactions between cellular materials and other substrates. Composite constructions can be in the form of complete finished products or representative small specimens cut there-from

This part of ISO 26842 gives guidelines to select, by means of delamination-resistance tests, adhesive/wood combinations in non-severe environments, in which the products are not exposed to extreme changes in temperature and humidity.

A series of exposure cycles at various temperature and humidity values is provided to verify that the adhesive selected, or a product bonded with the adhesive, meets the necessary requirements for resistance to delamination.

This part of ISO 26842 is intended to help the user not only to select a suitable adhesive, but also to evaluate adhesives and adhesively bonded wood products.

NOTE When actual wood products are tested using this method, the test results might not be comparable because the test laboratory will not normally have had adequate control over the way the product was assembled.

This part of ISO 26842 is not intended for use in the qualification of structural components.

This document defines quality and test methodologies for recycled PVC to be used in PVC window profile systems.

It contains a description of the controlled loop as such, the definition of those material transformation steps which are relevant for product quality, in particular recycling input and output and profile manufacturing input and output.

Traceability tools are specified to characterize this loop as a controlled loop.

With regard to PVC waste treatment, the present document relates to existing standards such as EN 15343, EN 15346 and EN 15347

With regard to semifinished and/or finished products, it refers to the European Standard for un-plasticized PVC window profiles (see EN 12608-1) and to the European harmonized standard for windows and doors (see EN 14351-1).

This document specifies a measuring method for the characterization of rheological properties of structural adhesives using oscillatory rheometry. The advantage of the method in comparison to rotational viscometry measurements lies in the separation of elastic and viscous material properties, thus allowing to define the viscoelastic properties. This enables more precise information concerning the flow behaviour of the materials, thereby resulting in a better understanding of their processing properties.

The method described is particularly suitable for filled and paste-like adhesives. These are frequently processed using automated pump and application systems in industrial applications and will be set precisely considering their rheological properties. As the rheological behaviour of uncured adhesives is mostly independent of their properties in the cured state, the standard can also serve for the examination of non-structural adhesives

This International Standard specifies characteristics for adhesives for floor coverings, which comprise

— resilient floor coverings (e. g. manufactured from plastics, linoleum or rubber);

— textile floor coverings.

Adhesives for floor coverings are intended for use within a building according to the manufacturer’s specification.

This International Standard specifies requirements for establishing performance characteristics of adhesives for floor coverings with regard to their determination, evaluation and expression.

This International Standard comprises all kinds of adhesives for floor coverings irrespective of the chemical composition and the mechanism of setting. Products according to this standard can be put on the market as liquids, pastes and film adhesives for floor coverings. The products may be one-component or multi-component.

This International Standard also defines a special kind of adhesives for floor coverings, which facilitate the easy removal of the floor covering after the utilization and where the need for a permanent bond is not always required. These types of floor covering adhesives will be referred as low peel strength, release bond adhesives.

This International Standard does not

— cover adhesives for bonding parquet to the subfloor, adhesives for bonding laminate floor coverings and adhesives for ceramic tiles;

— make provisions for testing the bond strength of low peel strength, release bond adhesives for floor coverings;

— take account of all influences which may occur in practice.

This International Standard specifies a method for the determination of the mass per unit area and five methods (Method A to Method E) for the determination of the fibre mass per unit area of moulding compounds and prepregs.

Method A: Extraction by soxhlet

Method B: Extraction by immersion in solvent in a beaker

Method C: Decomposition by loss ignition

Method D: Extraction by wet combustion

Method E: Method by calculation

This International Standard is applicable to the following types of material:

— moulding compound and preimpregnated unidirectional sheet, tape, fabric and mats.

— prepregs in which any type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix (thermosetting or thermoplastic) has been used.

Typically, reinforcement fibres are coated with sizing or finishes. These normally dissolve with the resin and are, therefore, included in the resin content.

This International Standard is not applicable to the following types of prepregs:

— these containing reinforcements which are soluble (or partly soluble) in the solvents used to dissolve the resin.

This document establishes a system of designation for polyoxymethylene (POM) thermoplastic material, which can be used as the basis for specifications.

NOTE Polyoxymethylene materials are thermoplastic materials composed principally of long-chain synthetic homopolymers and copolymers of formaldehyde. The repeating unit in the molecular chain is – CH2O – as an integral part of the main polymer chain resulting from polymerization of formaldehyde.

The types of polyoxymethylene plastic are differentiated from each other by a classification system based on appropriate levels of the following designatory properties:

a) melt mass-flow rate or melt volume-flow rate;

b) tensile modulus, and on information about basic polymer parameters, intended application, method of processing, important properties, additives, colorants, fillers and reinforcing materials.

This document is applicable to all polyoxymethylene homopolymers and to copolymers of polyoxymethylene and blends of polymers containing polyoxymethylene. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified and modified by colorants, additives, fillers, etc. It is not intended to imply that materials having the same designation necessarily give the same performance.

This document does not provide engineering data, performance data or data on processing conditions which can be required to specify materials for particular end-use applications. If such additional properties are required, they are to be determined in accordance with the test methods specified by the relevant International Standard.
