Polimerni materiali - Preskušanci (ISO 20753:2023)
Ta dokument določa dimenzijske zahteve za preskušance, pripravljene iz polimernih materialov in namenjene za obdelavo z oblikovanjem, ter za preskušance, pripravljene s strojno obdelavo iz trakov ali oblikovanih izdelkov. Podaja oznake in dimenzije za preskušance, uporabljene za pridobivanje primerljivih podatkov in za druge preskušance, ki se pogosto uporabljajo.
Določena sta naslednja tipa preskušancev:
a) preskušanci tipa A1 in tipa A2 (1 = oblikovani z vbrizganjem, 2 = strojno obdelani iz trakov ali oblikovanih izdelkov)
Preskušanci tipov A in B so natezni preskušanci, iz katerih je mogoče s preprosto strojno obdelavo pridobiti preskušance za različne druge preskuse (glej dodatek A).
Preskušanec tipa A1 je večnamenski preskušanec. Glavna prednost večnamenskega preskušanca je, da omogoča izvedbo vseh preskusnih metod, omenjenih v dodatku A, v vseh preskusnih laboratorijih na podlagi primerljivih oblikovancev. Posledično so merjene lastnosti skladne, saj se merijo z uporabo podobnih preskušancev, pripravljenih na enak način. Z drugimi besedami, mogoče je pričakovati, da se rezultati preskusa za podan nabor preskušancev ne bodo znatno razlikovali zaradi nenamerno drugačnih pogojev oblikovanja. Po drugi strani pa je mogoče po želji brez težav oceniti vpliv pogojev oblikovanja in/ali različnih stanj preskušancev za vse merjene lastnosti.
Opisani so tudi preskušanci v pomanjšanjem merilu, označeni kot vrsta Axy, kjer je x številka, ki označuje način priprave preskušanca, (1 – oblikovani z vbrizganjem, 2 – strojno obdelani iz trakov ali oblikovanih izdelkov) in y številka, ki označuje faktor lestvice, (1:y). Te je mogoče uporabiti na primer, ko uporaba preskušancev polne velikosti ni priročna ali ko je preskusni material na voljo samo v majhnih količinah.
b) Preskušanci tipa B
To so palični preskušanci, ki jih je mogoče neposredno oblikovati ali strojno obdelati iz osrednjega dela preskušancev tipa A1 oziroma iz trakov ali oblikovanih predmetov.
c) Preskušanci tipa C
To so majhni natezni preskušanci, ki jih je mogoče neposredno oblikovati ali strojno obdelati, npr. iz plošč (preskušanci tipa D), iz osrednjega dela preskušancev tipa A1 oziroma iz trakov ali oblikovanih predmetov.
d) Preskušanci tipa D1 in D2
To so kvadratne plošče debeline 1 mm in 2 mm.
e) Preskušanci tipa F
To so pravokotne plošče za uporabo pri analizi mehanske anizotropije.
Če določen tip preskušanca ni omenjen v tem dokumentu, to ne pomeni, da obstaja namen izključitve uporabe preskušanca. Drugi tipi preskušancev se lahko dodajo v prihodnje, če bodo pogosto uporabljeni.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2,
Mechanical behavior, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 20753:2018), which has been technically
revised.
The main changes are as follows:
— Clarified overview of dimensions for reduced-scale dumb bell specimen type A.
— That it contains harmonization of all tolerances for radii, widths and lengths, calculation of
the total tolerance for l (the length l including radii), which now includes the summary of
2 1
tolerances of the single dimensions.
— That dimension l is most important for a testing lab, as it needs to be observed to ensure
distance between grips at tensile test.
— Change of dimension of test specimen type CP. The dimension is now consistent with type 3 of
ISO 8256. The former dimension refers to type 2 of ISO 8256. However, the new dimension tends to
be used for high-speed tensile tests for crash simulation.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

ISO 20753:2023(E)
Introduction
Information on plastics test specimens has been specified in several different locations: in test method
standards (e.g. ISO 527-2), in ISO 3167 (for multipurpose test specimens) and in ISO 294-1, ISO 294-2,
ISO 294-3 and ISO 294-5 (for moulding conditions). The aim of this document is to give the designations
and dimensions of test specimens used for the acquisition of comparable data, and also of other
frequently used specimens, in one document for ease of reference. Other International Standards that
have hitherto used different designations for the same specimen type will also be revised to bring the
designations into line with those in this document.
