Plastics - Polyamides - Accelerated conditioning of test specimens (ISO 1110:1995)

The method described is based on storing the test specimens in an atmosphere of (70 ± 1) °C and (62 ± 1) % relative humidity (psychrometric temperature difference of (10 ± 0,3) °C), until moisture absorption by the specimen has reached at least 95 % of its equilibrium level. It is applicable to polyamides and copolyamides in grades containing fillers and other additives, but not to grades containing more than 2 % (m/m) extractables. The equilibrium moisture content attained is close to the equilibrium moisture content obtained in standard atmosphere 23/50.

Kunststoffe - Polyamide - Beschleunigte Konditionierung von Probekörpern (ISO 1110:1995)

Diese Norm beschreibt ein Verfahren zum beschleunigten Konditionieren von Probekörpern aus Polyamiden und Copolyamiden. Es eignet sich auch für Formmassen mit Füllstoffen und Additiven, jedoch nicht für Formmassen mit einem Gehalt an extrahierbaren Anteilen größer 2 % (m/m). Der nach diesem Verfahren erreichte Gleichgewichtsfeuchtegehalt eintspricht annähernd dem Gleichgewichtsfeuchtegehalt, der sich im Normklima 23/50 einstellt.

Plastiques - Polyamides - Conditionnement accéléré d'éprouvettes (ISO 1110:1995)

La présente Norme internationale prescrit une méthode pour le conditionnement accéléré d'éprouvettes des polyamides et copolyamides. La méthode peut aussi être appliquée aux qualités contenant des charges et autres additifs, mais pas aux qualités contenant plus de 2 % (m/m) de matières extractibles. Le taux d'humidité d'équilibre atteint par cette méthode correspond à peu près au taux d'humidité d'équilibre obtenu dans l'atmosphère normale 23/50. Les valeurs de propriétés mécaniques obtenues après conditionnement accéléré selon cette méthode peuvent différer légèrement de celles obtenues après conditionnement dans l'atmosphère normale 23/50.

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. Esch 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
(1 EC) 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 1110 was prepared by Technical Committee
lSO/lC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This third edition cancels and replaces the second edition
(ISO 11 IO:1 987), which has been technically revised.

Introduction
Various properties of polyamides (PA) depend upon their moisture content.
Reproducible values of these properties tan only be obtained with speci-
mens having a specified moisture content. Such specimens are obtained
by conditioning, i.e. by allowing them to resch equilibrium in an atmos-
phere with a specified temperature and relative humidity.
The rate of moisture absorption and, therefore, the rate of conditioning, is
a function of the temperature. This rate is very low at room temperature.
For example, a 4 mm thick test specimen of PA66 requires more than a
year to attain its equilibrium moisture content in Standard atmosphere
23/50 (see ISO 291). To condition specimens in a relatively short period
of time, higher temperatures are required. Such a method for accelerated
conditioning is presented in this International Standard.
