This document 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 ISO 527-1. NOTE 1   Unidirectional reinforced materials are covered by ISO 527-5. 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. 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); NOTE 2   Injection moulded specimens are covered by ISO 527-2. —    combinations of the above with unidirectional reinforcements and multidirectional reinforced materials constructed from unidirectional layers, provided such laminates are symmetrical; NOTE 3   Materials with completely or mainly unidirectional reinforcements are covered by ISO 527-5. —    finished products made from materials mentioned above. The reinforcement fibres covered include glass fibres, carbon fibres, aramid fibres and other similar fibres.

Specifies a method for the determination of the apparent density of a moulding powder or a granular material. The sample is pured through a specified funnel into a measuring cylinder of 100 cubiccentimeter capacity, the excess is removed with a straightedge and the mass of the contents is determinded by weighing. Expression of the apparent density in grams per millilitre.

A portion of 60 g of loose moulding material is dropped little by little into a measuring cylinder as evenly distributed as possible. A plunger with specified mass fitting to the measuring cylinder is slowly lowered until it is entirely supported by the material. After 1 min the volume of the material with the plunger resting upon it, shall be determined and the apparent density shall be calculated.

A test sample of 5 g is weighed into a weighing bottle and spread evenly over the bottom. The bottle is dried at 55 C. After 3 h the sample is remove from the open, cooled to room temperature and conditioned. The volatile matter is given as a percentage by mass.

ISO 19069-2:2016 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polypropylene (PP) moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given.

Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are also given. Properties and test methods which are suitable and necessary to characterize PP moulding and extrusion materials are listed.

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 part of ISO 19069, as are the designatory properties specified in ISO 19069‑1.

In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

This International Standard specifies a method for determining the durability of the adhesive joints of carbon fibre reinforced plastics (CFRPs) and metal assemblies by a wedge rupture test using a double cantilever beam (DCB) specimen under specified environmental conditions. This method is intended for evaluating the safety and reliability of adhesives, primers, and surface treatments of the adherends.

ISO 16620-4:2016 specifies a method of determining the biobased mass content in plastics products, based on the radiocarbon analysis and elemental analysis.

ISO 16620-4:2016 is applicable to plastic products and plastic materials, polymer resins, monomers or additives, which are made from biobased or fossil-based constituents.

This method is applicable, provided that the plastic product contains carbon element and that a statement giving its elemental composition and its biobased mass content is available.

This document specifies a test method for the determination of the opening, closing and running torque of thermoplastics valves. This test is considered to be performed as part of the initial type testing.
This document applies to all types of thermoplastics valves intended to be used for the transport of fluids.

NOTE 1 Examples of valve types tested with this method are in ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 21787, ISO 4437-4, ISO 16486-4, EN 12201-4, EN 1555-4.

It does not specify the relationship between the torque and its possible increase after valve prolonged use at specific working condition or materials wear/chemical aggression.

NOTE 2 Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358; concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closure, further information is provided in ISO 8659.
