Die Werkzeuge können zusätzlich mit Einsätzen versehen werden zur Untersuchung der Wirkung von Fließnähten auf mechanische Eigenschaften (siehe Anhang B).

Plastiques - Moulage par injection d'éprouvettes en compositions de poudre à mouler (PMC) thermodurcissables -Partie 2: Petites plaques (ISO 10724-2:1998)

La présente partie de l'ISO 10724 spécifie deux types de moules à deux empreintes, les moules ISO Dl et D2, pour le moulage par injection de petites plaques mesurant 60 mm x 60 mm avec des épaisseurs préférentielles de 1 mm (type D1) ou 2 mm (type D2) pouvant être utilisées pour un grand nombre d'essais (voir annexe A). Les moules peuvent en outre être équipés d'inserts pour étudier les effets des lignes de soudure sur les caractéristiques mécaniques (voir annexe B).

[e-mail] in SwitzerlandiiForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.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.International Standard ISO 10724-2 was prepared by Technical Committee ISO/TC 61, Plastics, SubcommitteeSC 12, Thermosetting materials.Together with part 1, this part of ISO 10724 cancels and replaces ISO 10724:1994, which has been revised toimprove the definition of the injection-moulding parameters and has been restructured to specify two types of ISOmould for the production of the basic specimen types required for the acquisition of comparable test data.Care has been taken to ensure that the ISO moulds described can all be fitted in existing injection-mouldingequipment and have interchangeable cavity plates.As far as possible, the wording of this part of ISO 10724 and its definitions corresponds to that in its counterpart forthermoplastic materials, ISO 294:1996, Plastics — Injection moulding of test specimens of thermoplastic materials.Unlike the latter, however, there is no need for the separate moulding of rectangular bars (80 mm ´ 10 mm ´ 4 mm,which should be taken from the central portion of the multipurpose test specimen) and the moulding of small tensilebars (> 60 mm ´ 10 mm ´ 3 mm). Therefore the type B and type C ISO moulds specified in ISO 294 were notincluded in this part of ISO 10724. Regardless of this, and to avoid confusion, the designation of the different mouldtypes in this part of ISO 10724 and in ISO 294 correspond to each other.ISO 10724 consists of the following parts, under the general title Plastics — Injection moulding of test specimens ofthermosetting powder moulding compounds (PMCs):—
Part 1: General principles and moulding of multipurpose test specimens—
Part 2: Small platesAnnexes A to D of this part of ISO 10724 are for information only.SIST EN ISO 10724-2:2001



© ISOISO 10724-2:1998(E)iiiIntroductionMany factors in the injection-moulding process which can influence the properties of moulded test specimens andhence the measured values obtained when the specimens are used in a test method. The thermal and mechanicalproperties of such specimens are in fact strongly dependent on the conditions of the moulding process used toprepare the specimens. Exact definition of each of the main parameters of the moulding process is a basicrequirement for reproducible and comparable operating conditions.It is important in defining moulding conditions to consider any influence the conditions may have on the properties tobe determined. Thermosets may show differences in orientation of anisotropic fillers such as short fibres and incuring.
