Plastics - Phenolic powder moulding compounds (PF-PMCs) - Part 2: Preparation of test specimens and determination of properties (ISO 14526-2:1999)
This part of ISO 14526 specifies the methods of preparation of test specimens and the test methods to be used in
determining the properties of phenolic powder moulding compounds (PF-PMCs). Requirements for handling test
material and for conditioning both the test material before moulding and the specimens before testing are given
here.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the
materials from which these specimens are made are given. Properties and test methods which are suitable and
necessary to characterize PMCs 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, PMCs are also included in this part of ISO 14526, as are the designatory
properties found in ISO 14526-1.
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.
Plastiques - Poudres à mouler phénoliques (PF-PMC) - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 14526-2:1999)
La présente partie de l'ISO 14526 spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai à
appliquer pour déterminer les propriétés des poudres à mouler (PMC). Elle fixe les exigences concernant, d'une
part, le traitement du matériau pour essai, et d'autre part, le conditionnement du matériau pour essai avant
moulage et des éprouvettes avant les essais.
Elle précise les modes opératoires et les conditions à appliquer pour la préparation des éprouvettes et pour le
mesurage des propriétés des matériaux à partir desquels sont fabriquées les éprouvettes. Elle fournit une liste des
propriétés et des méthodes d'essai appropriées et nécessaires à la caractérisation des PMC.
Ces propriétés ont été choisies parmi les méthodes d'essai générales de l'ISO 10350-1. D'autres méthodes d'essai
largement utilisées avec les PMC, ou présentant une importance particulière, sont également incluses dans la
présente partie de l'ISO 14526, tout comme les propriétés de désignation données dans l'ISO 14526-1.
Pour obtenir des résultats reproductibles et comparables, il est nécessaire d'utiliser les méthodes de préparation et
de conditionnement, les dimensions d'éprouvettes et les modes opératoires d'essai spécifiés dans le présent
document. Les valeurs déterminées ne seront pas nécessairement identiques à celles obtenues en utilisant des
éprouvettes de dimensions différentes ou préparées selon d'autres modes opératoires.

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 3.
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 part of ISO 14526 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 14526-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 12, Thermosetting materials.
After a transition period of, at the most, four years, the three parts of ISO 14526 (see below) will replace
ISO 800:1992, of which they constitute a technical revision.
ISO 14526 consists of the following parts, under the general title Plastics — Phenolic powder moulding compounds
(PF-PMCs):
� Part 1: Designation system and basis for specifications
� Part 2: Preparation of test specimens and determination of properties
� Part 3: Requirements for selected moulding compounds

3 Terms and definitions
For the purposes of this part of ISO 14526, the terms and definitions given in ISO 472 and ISO 14526-1 apply, plus
the following:
3.1
thermal flow
parameter which characterizes the flow behaviour of plasticized thermosetting moulding compounds, e.g. when
filling a mould cavity, and for which the minimum torque M measured in accordance with ISO 15062 may be taken
B
as a measure
4 Preparation of test specimens
4.1 General
It is essential that specimens are always prepared by the same procedure (either injection moulding or
compression moulding), using the same processing conditions.
The procedure to be used for each test method is indicated in Tables 3 and 4 (M = injection moulding,
Q = compression moulding).
4) To be published.

ISO 14526-2:1999(E)
The material shall be kept in moisture-proof containers until it is required for use.
The moisture content of filled or reinforced materials shall be expressed as a percentage of the total mass of the
compound.
4.2 Pretreatment of the material
Before processing by injection moulding, no treatment of the sample is normally necessary. If pretreatment is
required, this shall be in accordance with the manufacturer's recommendations.
Before processing by compression moulding, treatment of the sample in accordance with ISO 295:—,
subclause 5.2 (preforming), 6.2 (drying), 6.3 (high-frequency preheating) or 6.4 (preplastification), is allowed.
4.3 Injection moulding
Injection-moulded specimens shall be prepared in accordance with ISO 10724-1 and/or ISO 10724-2, using the
conditions specified in Table 1.

The conditions may be selected from within the range specified in Table 1 provided that the statement in 4.1, first
sentence, is observed and, in each specific case, definite values (not ranges) are laid down for

type of PF-PMC and is stated together with the test results. The cure time selected shall ensure that all the
specimens are cured as completely and homogeneously as possible.
NOTE For PF-PMCs with high thermal flow, the following situation may occur:
— injection moulding of certain mouldings with the intended quality is possible but
— injection moulding of test specimens (e.g. ISO 3167 type A multipur
