1.1 This part of ISO 527 specifies the test conditions for the determination of the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general principles given in part 1.

Unidirectionally reinforced materials are covered by Part 5.

1.2 The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus, Poisson's ratios and other aspects of the tensile stress/strain relationship under the defined conditions.

1.3 The test method is suitable for use with the following materials:

—    fibre-reinforced thermosetting and thermoplastic composites incorporating non-unidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combinations of such reinforcements, hybrids, rovings, short or milled fibres or preimpregnated materials (prepregs) (for directly injection-moulded specimens, see specimen 1A in ISO 527-2);

—    combinations of the above with unidirectional reinforcements and multidirectional reinforced materials constructed from unidirectional layers, provided such laminates are symmetrical (for materials with completely, or mainly, unidirectional reinforcements, see ISO 527-5);

—    finished products made from these materials.

The reinforcement fibres covered include glass fibres, carbon fibres, aramid fibres and other similar fibres.

1.4 The method is performed using specimens machined from a test panel made in accordance with ISO 1268 or by equivalent methods, or from finished and semi-finished products with suitable flat areas.

This document specifies an oven-drying method for the determination of the dry matter content in suspensions of cellulosic nanomaterials. The procedure is applicable to cellulosic nanomaterial suspensions which do not contain any appreciable quantities of materials other than water that are volatile at the temperature of 105 °C ± 2 °C. It is used, for example, in the case of cellulosic nanomaterial suspensions samples taken for chemical and physical tests in the laboratory, when a concurrent determination of dry matter content is required.

NOTE 1:  ISO 638-1 [1] specifies the total dry matter content of paper, board, paper and board for recycling and cellulosic nanomaterials in solid form; ISO 287 [2] specifies the determination of moisture content of a lot of paper and board; ISO 4119 [3] specifies the determination of stock concentration of aqueous pulp suspensions; ISO 801 (all parts) [4] specifies the determination of saleable mass in lots.

NOTE 2:  This document determines the total dry matter content of the sample, including any dissolved solids. If only the cellulosic material content free of dissolved solids is desired, dissolved solids should be removed prior to measuring the dry matter content e.g. by washing or dialysis, taking care to retain all cellulosic material.

This document gives guidance and requirements for the design and calculation methods, installation, acceptance testing, routine testing and maintenance for pressure differential systems (PDS).
PDSs are designed to hold back smoke at a leaky physical barrier in a building, such as a door (either open or closed) or other similarly restricted openings and to keep tenable conditions in escape and access routes depending on the application.
It covers systems intended to protect means of escape e.g. staircases, corridors, lobbies, as well as systems intended to provide a protected firefighting bridgehead for the fire services.
It provides details on the critical features and relevant procedures for the installation.
It describes the commissioning procedures and acceptance testing criteria required to confirm that the calculated design is achieved in the building.
This document gives complete rules, requirements and procedures to design PDS for buildings up to 60 m.
For buildings taller than 60 m the same requirements are given (e.g. Table 1), but additional calculations and verification methods are necessary. Requirements for such methods and verification are given in Annex D, but the methods fall outside the scope of this document [e.g. Computational Fluid Dynamics (CFD)].
Routine testing and maintenance requirements are also defined in the document.
In the absence of national requirements and under expected ambient and outside conditions, the requirements in Table 1 are fulfilled by the PDS.

This document specifies a method, by measuring the amount of carbon dioxide evolved, for the determination of the degree of aerobic biodegradability of plastic materials, including those containing formulation additives. The test material is exposed in a synthetic medium under standardized laboratory conditions to an inoculum from activated sludge under aerobic, mesophilic conditions.

If an unadapted activated sludge is used as the inoculum, the test result can be used to assess the aerobic biodegradation processes which occur in a waste water treatment plant environment. If a mixed or pre-exposed inoculum is used, the method can be used to investigate the potential biodegradability of a test material.

The conditions used in this document do not necessarily correspond to the optimum conditions allowing maximum biodegradation to occur, but this test method is designed to measure the biodegradation of plastic materials and give an indication of their potential biodegradability.

The method enables the assessment of the biodegradation to be improved by calculating a carbon balance (optional, see Annex C).

The method applies to the following materials:

—    natural and/or synthetic polymers, copolymers or mixtures thereof;

—    plastic materials which contain additives such as plasticizers, colorants or other compounds;

—    water-soluble polymers;

—    materials which, under the test conditions, do not inhibit the microorganisms present in the inoculum. Inhibitory effects can be determined using an inhibition control or by another appropriate method (see, for example, ISO 8192[1]). If the test material is inhibitory to the inoculum, a lower test concentration, another inoculum or a pre-exposed inoculum can be used.
