Plastics - Test specimens (ISO 20753:2018)
This document specifies dimensional requirements relating to test specimens prepared from plastics
materials intended for processing by moulding, as well as to test specimens prepared by machining
from sheets or shaped articles. It compiles the designations and dimensions of test specimens used for
the acquisition of comparable data and also of other frequently used specimens.
The following types of test specimen are specified:
a) Type A1 and type A2 specimens (1 = injection moulded, 2 = machined from a sheet or shaped
article)
These are tensile test specimens from which, with simple machining, specimens for a variety of
other tests can be taken (see Annex A).
The type A1 specimen is a multipurpose test specimen. The principal advantage of a multipurpose
test specimen is that it allows all the test methods mentioned in Annex A to be carried out by all
test laboratories on the basis of comparable mouldings. Consequently, the properties measured
are coherent as all are measured using similar specimens prepared in the same way. In other
words, it can be expected that test results for a given set of specimens will not vary appreciably
due to unintentionally different moulding conditions. On the other hand, if desired, the influence of
moulding conditions and/or different states of the specimens can be assessed without difficulty for
all of the properties measured.
Also described are reduced-scale test specimens designated type Axy, where x is the number
indicating the method of specimen preparation (1 = injection moulded, 2 = machined from a sheet
or shaped article) and y is a number indicating the scale factor (1:y). These can be used e.g. when
full-sized test specimens are not convenient or when sample material exists in small quantities only.
b) Type B specimens
These are bar specimens which can be directly moulded or can be machined from the central
section of type A1 specimens or from sheets or shaped articles.
c) Type C specimens
These are small tensile test specimens which can be directly moulded or machined, e.g. from plates
(Type D or type F specimens), from the central section of type A1 specimens or from sheets or
shaped articles.
d) Type D1 and type D2 specimens
These are square plates of thickness 1 mm and 2 mm, respectively.
e) Type F specimens
These are rectangular plates intended for use in the analysis of mechanical anisotropy.
If a particular type of test specimen is not mentioned in this document, this does not mean that there
is any intention to exclude the use of the specimen. Additional specimen types can be added in future if
they are commonly used.
Kunststoffe - Probekörper (ISO 20753:2018)
Plastiques - Éprouvettes (ISO 20753:2018)
Le présent document fixe des spécifications relatives aux dimensions des éprouvettes préparées à partir de matières plastiques et destinées au traitement par moulage par injection ainsi que des éprouvettes préparées par usinage à partir de feuilles ou d'articles façonnés. Il compile les désignations et les dimensions des éprouvettes utilisées pour l'acquisition de données comparables ainsi que d'autres éprouvettes fréquemment utilisées.
Les types d'éprouvette suivants sont spécifiés:
a) Éprouvettes de type A1 et de type A2 (1 = moulées par injection, 2 = usinées dans une feuille ou un article façonné)
Il s'agit d'éprouvettes destinées à la traction à partir desquelles, par simple usinage, on peut obtenir des éprouvettes pour une variété d'autres essais (voir Annexe A).
L'éprouvette de type A1 est une éprouvette à usages multiples. Le principal avantage de l'éprouvette à usages multiples est qu'elle permet à tous les laboratoires d'essai de réaliser toutes les méthodes d'essai mentionnées dans l'Annexe A à partir de moulages similaires. En conséquence, les propriétés mesurées au moyen de ces éprouvettes sont cohérentes étant donné qu'elles sont toutes mesurées avec des éprouvettes similaires préparées de la même manière. En d'autres termes, on peut s'attendre à ce que les résultats obtenus avec une série donnée d'éprouvettes ne varieront pas de façon sensible par suite de conditions de moulage involontairement différentes. D'autre part, si on le désire, l'influence des conditions de moulage et/ou des différents états des éprouvettes peut être déterminée sans difficulté pour l'ensemble des propriétés mesurées.
Des éprouvettes à échelle réduite, désignées Axy, sont également décrites, x étant le nombre indiquant la méthode de préparation de l'éprouvette (1 = moulée par injection, 2 = usinée dans une feuille ou un article façonné) et y le nombre indiquant le facteur d'échelle (1:y). Elles peuvent par exemple être utilisées lorsqu'il n'est pas pratique d'utiliser des éprouvettes à taille réelle ou que le matériau échantillon n'existe qu'en petite quantité.
b) Éprouvettes de type B
Il s'agit de barreaux pouvant être directement moulés ou pouvant être usinés dans la section centrale des éprouvettes de type A1 ou dans des feuilles ou des articles façonnés.
c) Éprouvettes de type C
Il s'agit d'éprouvettes de petites dimensions destinées à la traction pouvant être directement moulées ou usinées, par exemple dans des plaques (éprouvettes de type D ou de type F), dans la section centrale des éprouvettes de type A1 ou dans des feuilles ou des articles façonnés.
d) Éprouvettes de type D1 et de type D2
Il s'agit de plaques carrées de 1 mm et 2 mm d'épaisseur, respectivement.
e) Éprouvettes de type F
Il s'agit de plaques rectangulaires destinées à l'analyse de l'anisotropie mécanique.
Si un type particulier d'éprouvettes n'est pas mentionné dans le présent document, cela ne signifie aucunement qu'il existe une intention d'exclure l'utilisation de l'éprouvette. Des types d'éprouvette supplémentaires pourront être ajoutés à l'avenir s'ils sont fréquemment utilisés.
Polimerni materiali - Preskušanci (ISO 20753:2018)
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.
