(Main)Plastics - Injection moulding of test specimens of thermoplastic materials - Part 5: Preparation of standard specimens for investigating anisotropy (ISO 294-5:2011)
General Information
- Abstract
ISO 294-5:2011 specifies a two-cavity mould (designated the type F ISO mould) for the injection moulding of 80 mm x 90 mm plates with a preferred thickness of 2 mm for single-point data acquisition because 2 mm has been found to provide the maximum anisotropic properties, with only a slight sensitivity to the rate of injection. For the design of plastic parts, this will provide upper and lower bounds for the tensile properties. Matching the plate thickness to a given part thickness is not a suitable criterion because of the effect of mould filling rate and part geometry on anisotropy. Suitable test specimens [ISO 527‑2 type 1BA tensile test specimens or type 1 (80 mm x 10 mm) bars] are then machined or die-cut from the plates and used to obtain information on the anisotropy of thermoplastic parts.
Investigation of the anisotropy of materials is a special procedure intended to provide guidance in the design of mouldings for end-use applications and is not intended as a quality control tool.
In the injection moulding of thermoplastic materials, the flow of molten polymer may influence the orientation of fillers such as fibreglass or the orientation of polymer chains. This can result in anisotropic behaviour. The knowledge of anisotropic behaviour is valuable in designing plastic parts.

ISO 294-5:2011(E) iv © ISO 2011 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 294-5 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This second edition cancels and replaces the first edition (ISO 294-5:2001), which has been technically revised. The main change concerns the thickness of the test specimens produced, which is now 2 mm as opposed to 3 mm in the previous edition. In addition, the maximum mould-locking force in 4.2 has been recalculated. It also cancels and replaces the Amendment ISO 294-5:2001/Amd.1:2004. In addition, it incorporates the Technical Corrigendum ISO 294-5:2001/Cor.1:2003. ISO 294 consists of the following parts, under the general title Plastics — Injection moulding of test specimens of thermoplastic materials: Part 1: General principles, and moulding of multipurpose and bar test specimens Part 2: Small tensile bars Part 3: Small plates Part 4: Determination of moulding shrinkage Part 5: Preparation of standard specimens for investigating anisotropy
ISO 294-5:2011(E) © ISO 2011 – All rights reserved v Introduction Reinforced and self-reinforcing injection-mouldable thermoplastics are used in a wide variety of applications, some of which can be safety-related. During the injection-moulding process, reinforcement fibres can preferentially align with the flow of the molten material and not across the flow direction. This preferential alignment causes an imbalance in the properties of the moulded thermoplastic so that, in the flow direction, the alignment of the reinforcing fibres causes a higher strength and stiffness than in the cross direction with fewer aligned fibres. This difference in properties is termed anisotropy, and it may result in an injection-moulded component having less than the desired or designed strength. To aid designers in understanding the potential strength of an injection-moulded component, it is desirable to know about the anisotropy of an injection-moulded component. During the development of this part of ISO 294, it was found that injection-moulded test specimens do not exhibit the same fibre alignment across their thickness, but that the outer layers have fibre
