Plastics - Unplasticized poly(vinyl chloride) (PVC-U) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 21306-2:2019)

This document specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of PVC-U moulding and extrusion materials. Requirements for handling
test materials and for conditioning both the test material before moulding and the specimens before
testing are given.
The properties required for the designation of PVC-U thermoplastics are given in ISO 21306-1. All
properties are intended to be determined by the appropriate methods referred to in this document and
values obtained shall be presented as laid down in ISO 10350-1.
The values determined in accordance with this document are not necessarily be identical to those
obtained using specimens of different dimensions and/or prepared by different procedures. The values
obtained for the properties of a moulding depend on the moulding compound, the shape, the test
method and the state of anisotropy. The last-mentioned depends on the gating of the mould and the
moulding conditions, for example temperature, pressure and injection rate. Any subsequent treatment
is also be considered, for example conditioning or annealing.
The thermal history and the internal stresses of the specimens can strongly influence the thermal and
mechanical properties and the resistance to environmental stress cracking, but exert less effect on the
electrical properties, which depend mainly on the chemical composition of the moulding compound.
In order to obtain reproducible and comparable test results, the methods of preparation and
conditioning, the specimen dimensions and the test procedures specified herein are used. Values
determined are not necessarily be identical to those obtained using specimens of different dimensions
or prepared using different procedures.

Kunststoffe - Weichmacherfreie Polyvinylchlorid (PVC-U)-Werkstoffe - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 21306-2:2019)

Dieses Dokument legt die Verfahren für die Herstellung von Probekörpern fest sowie die Prüfverfahren, die für die Bestimmung der Eigenschaften von PVC-U-Werkstoffen anzuwenden sind. Es werden Anforderungen für den Umgang mit den zu prüfenden Werkstoffen und für die Konditionierung von sowohl den zu prüfenden Werkstoffen vor dem Formen als auch der Probekörper vor der Prüfung angegeben.
Die Eigenschaften, die für die Kennzeichnung von PVC-U-Thermoplasten erforderlich sind, werden in ISO 21306 1 festgelegt. Es wird beabsichtigt, alle Eigenschaften nach den in diesem Dokument aufgeführten geeigneten Prüfverfahren zu bestimmen und die ermittelten Daten müssen nach ISO 10350 1 dargestellt werden.
Die nach diesem Dokument bestimmten Werte sind nicht zwingenderweise mit denen identisch, die bei Anwendung von Probekörpern anderer Abmessungen und/oder solchen, die mit einem anderen Verfahren hergestellt wurden, erhalten werden. Die Eigenschaftswerte eines Formteils hängen von der Formmasse, der Form, dem Prüfverfahren und dem Anisotropiezustand ab. Letzteres hängt von der Spritzdüse und den Spritzbedingungen wie z. B. Temperatur, Druck und Einspritzgeschwindigkeit ab. Auch nachfolgende Behandlungen, wie z. B. Konditionieren oder Tempern, werden berücksichtigt.
Die thermische Vorgeschichte und die inneren Spannungen der Probekörper können die thermischen und mechanischen Eigenschaften sowie die Spannungsrissempfindlichkeit stark beeinflussen, aber wirken sich weniger auf elektrische Eigenschaften aus, die im Wesentlichen von der chemischen Zusammensetzung der Formmasse abhängen.
Mit dem Ziel, reproduzierbare und vergleichbare Prüfergebnisse zu erhalten, werden die hier festgelegten Verfahren für Herstellung und Konditionierung von Probekörpern, Maße für Probekörper und Prüfverfahren angewendet. Die bestimmten Werte sind nicht zwingenderweise mit denen identisch, die bei Anwendung von Probekörpern anderer Abmessungen oder solchen, die mit anderen Verfahren hergestellt wurden, erhalten werden.

Plastiques - Matériaux à base de poly(chlorure de vinyle) non plastifié (PVC-U) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 21306-2:2019)

Le présent document spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai à utiliser dans la détermination des propriétés de matériaux à base de PVC-U pour moulage et extrusion. Les exigences relatives à la manipulation du matériel d'essai et au conditionnement à la fois du matériel d'essai avant le moulage et des échantillons avant l'essai sont indiquées.
Les propriétés nécessaires à la désignation des thermoplastiques à base de PVC-U sont données dans l'ISO 21306-1. Toutes les propriétés doivent être déterminées au moyen des méthodes appropriées mentionnées dans le présent document et les valeurs obtenues doivent être présentées conformément à l'ISO 10350‑1.
Les valeurs déterminées conformément au présent document ne seront pas nécessairement identiques à celles obtenues en utilisant des éprouvettes de dimensions différentes et/ou préparées selon des modes opératoires différents. Les valeurs obtenues pour les propriétés d'un objet moulé dépendent de la matière à mouler, de la forme de l'objet, de la méthode d'essai et de l'état d'anisotropie. Ce dernier est fonction du canal d'alimentation du moule et des conditions de moulage, par exemple de la température, de la pression et de la vitesse d'injection. Tout traitement ultérieur, tel que le conditionnement ou le recuit, doit également être pris en considération.
Les antécédents thermiques et les tensions internes des éprouvettes peuvent influencer fortement leurs propriétés thermiques et mécaniques, ainsi que leur résistance à la fissuration sous contrainte dans un environnement donné ; toutefois, leur impact sur les propriétés électriques des éprouvettes est moins marqué car ces propriétés dépendent principalement de la composition chimique de la matière à mouler.
Pour obtenir des résultats d'essai reproductibles et comparables, les méthodes de préparation et de conditionnement, les dimensions de l'éprouvette et les modes opératoires d'essai spécifiés ici sont utilisés. Les valeurs déterminées ne sont pas nécessairement identiques à celles obtenues avec des éprouvettes de dimensions différentes ou préparées selon des modes opératoires différents.

Polimerni materiali - Nemehčane zmesi homo- in kopolimerov vinilklorida za oblikovanje in ekstrudiranje - 2. del: Priprava preskušancev in ugotavljanje lastnosti (ISO 21306-2:2019)

Ta dokument določa metode za pripravo preskušancev in preskusnih metod za uporabo pri ugotavljanju lastnosti materialov PVC-U za oblikovanje in ekstrudiranje. Podane so zahteve za ravnanje s preskusnimi materiali ter pripravo preskusnega materiala pred oblikovanjem in preskušancev pred preskusom.
Lastnosti, potrebne za označevanje plastomerov PVC-U, so podane v standardu ISO 21306-1. Vse lastnosti se določijo z ustreznimi metodami iz tega dokumenta, dobljene vrednosti pa je treba predstaviti v skladu s standardom ISO 10350-1.
Pri tem ni nujno, da bodo vrednosti, ugotovljene v skladu s tem dokumentom, enake tistim, ki so pridobljene z uporabo preskušancev, ki imajo drugačne mere in/ali so pripravljeni z drugimi postopki. Vrednosti, dobljene za lastnosti oblikovanja, so odvisne od kalupne mase, oblike, preskusne metode in stanja anizotropije. Zadnje omenjeno je odvisno od livnega sistema kalupa in pogojev oblikovanja, na primer temperature, tlaka in hitrosti vbrizgavanja. Upoštevati je treba tudi vsako nadaljnjo obdelavo, na primer poboljšanje ali žarjenje.
Termična zgodovina in notranje napetosti preskušancev lahko močno vplivajo na toplotne in mehanske lastnosti ter na odpornost na razpoke zaradi obremenitev iz okolja, vendar imajo manjši vpliv na električne lastnosti, ki so odvisne predvsem od kemične sestave kalupne mase. Za zagotovitev primerljivih in ponovljivih rezultatov preskusa je treba uporabljati metode priprave in obdelave, mere preskušanca ter preskusne postopke, ki so navedeni v tem delu. Pri tem ni nujno, da so ugotovljene vrednosti enake tistim, ki so pridobljene z uporabo preskušancev, ki imajo drugačne mere ali so pripravljeni z uporabo drugih postopkov.
