Plastics - Fluoropolymer dispersions and moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 20568-1:2017)

ISO 20568-1:2017 establishes a system of designation for fluoropolymer materials, which may be used as the basis for specifications.
The various types of fluoropolymer are differentiated from each other by a classification system based on appropriate levels of the designatory properties and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.

Kunststoffe — Fluorpolymerdispersionen, Formmassen und Extrusionswerkstoffe — Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 20568-1:2017)

Dieses Dokument legt ein Bezeichnungssystem für Fluorpolymere fest, das als Grundlage für Spezifikationen verwendet werden kann.
Die verschiedenen Typen von Fluorpolymeren werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften und auf Informationen über die vorgesehene Anwendung und/oder Verarbeitungsverfahren, wichtige Eigen-schaften, Zusatzstoffe, Farbstoffe, Füll- und Verstärkungsstoffe, beruht.

Plastiques - Polymères fluorés: dispersions et matériaux pour moulage et extrusion - Partie 1: Système de désignation et base de spécification (ISO 20568-1:2017)

ISO 20568-1:2017 établit un système de désignation des matériaux polymères fluorés qui peut être utilisé comme base pour les spécifications.
Les types de polymères fluorés sont différenciés les uns des autres par un système de classification fondé sur des niveaux appropriés des propriétés de désignation et sur des informations sur l'application prévue et/ou la méthode de mise en ?uvre, les propriétés importantes, les additifs, les colorants, les charges et les matériaux de renfort.

Polimerni materiali - Disperzije in materiali za oblikovanje in ekstrudiranje na osnovi fluoropolimerov - 1. del: Sistem označevanja in podlage za specifikacije (ISO 20568-1:2017)

Ta dokument določa sistem označevanja materialov iz fluoropolimernih materialov, ki jih je mogoče uporabiti kot podlago za specifikacije.
Različne vrste fluoropolimerov se ločujejo glede na sistem razvrščanja, ki temelji na ustreznih ravneh označevalnih lastnostih in na informacijah o načrtovani uporabi in/ali metodi obdelave, pomembnih lastnostih, aditivih, barvilih, polnilih ter materialih za ojačanje.
Za politetrafluoroetilen (PTFE)
Za materiale za oblikovanje in ekstrudiranje na osnovi PTFE in za smole PTFE, pridobljene s koagulacijo disperzije:
– standardna specifična težnost (SSG)
– prostorninska gostota
– velikost zrn
Za vodne disperzije PTFE
– odstotek PTFE v disperziji
– odstotek površinsko aktivnih snovi v disperziji
– stopnja tolerance površinsko aktivnih snovi
Za smole, ki se obdelujejo s taljenjem
Za CPT, ECTFE, EFEP, ETFE, FEP, PFA, PVDF, PVF, VDF/CTFE, VDF/HFP, VDF/TFE, VDF/TFE/HFP
– temperatura tališča
– prostorninski pretok taline
Za PCTFE
– čas ničelne trdnosti (ZST)
Za TFE/PDD
– temperaturna prehodnost stekla (Tg)
Za vodne disperzije smol, ki se obdelujejo s taljenjem (ETFE, FEP, PFA, PVDF, PVF, VDF/CTFE,
VDF/HFP, VDF/TFE, VDF/TFE/HFP)
– odstotek polimera v disperziji
– odstotek površinsko aktivnih snovi v disperziji
– stopnja tolerance površinsko aktivnih snovi
Sistem označevanja se uporablja za vse fluoropolimere in mešanice. Uporablja se za nespremenjene materiale, pripravljene za običajno uporabo, in materiale, ki so spremenjeni na primer z barvili, aditivi, polnili, armirnimi materiali in modifikatorji polimerov.
Materiali z enako oznako nimajo nujno tudi enakih lastnosti. Ta dokument ne podaja inženirskih podatkov, podatkov o delovanju ali podatkov o pogojih obdelave, ki so morda potrebni za določitev materiala. Če so take dodatne lastnosti zahtevane, se določijo v skladu s preskusnimi metodami iz standarda ISO 20568-2, če je to primerno.
Za namene določitve plastomernega materiala za določeno specifikacijo, je treba v podatkovnem bloku 5 navesti dodatne zahteve (glej točko 4.1).

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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

INTERNATIONAL STANDARD ISO 20568-1:2017(E)
Plastics — Fluoropolymer dispersions and moulding and
extrusion materials —
Part 1:
Designation system and basis for specifications
1 Scope
This document establishes a system of designation for fluoropolymer materials, which may be used as
the basis for specifications.
The various types of fluoropolymer are differentiated from each other by a classification system based
on appropriate levels of the designatory properties and on information about the intended application
and/or method of processing, important properties, additives, colorants, fillers and reinforcing
materials.
For polytetrafluoroethylene (PTFE)
For PTFE granular moulding and ram extrusion materials, and for PTFE resin produced from
coagulation of dispersion:
— standard specific gravity (SSG)
— bulk density
— particle size
For aqueous dispersion of PTFE
— PTFE percentage in dispersion
— surfactant percentage in dispersion
— surfactant tolerance level
For melt processable resins
For CPT, ECTFE, EFEP, ETFE, FEP, PFA, PVDF, PVF, VDF/CTFE, VDF/HFP, VDF/TFE, VDF/TFE/HFP
— melting-peak temperature
— melt mass-flow rate
For PCTFE
— zero-strength time (ZST)
For TFE/PDD
— glass transition temperature (T )
g
For aqueous dispersion of melt processable resins (ETFE, FEP, PFA, PVDF, PVF, VDF/CTFE,
VDF/HFP, VDF/TFE, VDF/TFE/HFP)
— polymer percentage in dispersion
— surfactant percentage in dispersion
ISO 20568-1:2017(E)
— surfactant tolerance level
The designation system is applicable to all fluoropolymers and blends. It applies to unmodified materials
ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing
materials and polymer modifiers.
It is not intended to imply that materials having the same designation give necessarily the same
performance. This document does not provide engineering data, performance data or data on processing
conditions which may be required to specify a material. If such additional properties are required, they
are intended to be determined in accordance with the test methods specified in ISO 20568-2, if suitable.
In order to specify a thermoplastic material for a particular specification, the requirements are to be
given in data block 5 (see 4.1).
