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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 12086-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
This second edition cancels and replaces the first edition (ISO 12086-1:1995), which has been technically
revised.
ISO 12086 consists of the following parts, under the general title Plastics — Fluoropolymer dispersions and
moulding and extrusion materials:
⎯ Part 1: Designation system and basis for specifications
⎯ Part 2: Preparation of test specimens and determination of properties

INTERNATIONAL STANDARD ISO 12086-1:2006(E)

Plastics — Fluoropolymer dispersions and moulding and
extrusion materials —
Part 1:
Designation system and basis for specifications
1 Scope
1.1 This part of ISO 12086 establishes a system of designation for fluoropolymer materials that may be
used as the basis for specifications. It covers the homopolymers and various copolymers of fluoromonomers
used as dispersions and for moulding, extrusion and other specialized applications. This part of ISO 12086
describes the designation system and provides codes and tables of values for the designatory properties. The
designation system is applicable both to conventional thermoplastic fluoropolymers, processed by various
techniques, and those materials that are processed by the unique operations required for the
non-conventional thermoplastic polytetrafluoroethylene. The materials include both the fluorocarbon polymers
and the various other fluoropolymers as virgin polymers or processed for reuse or recycling. This part of
ISO 12086 also includes an extension of the designation system that provides a basis for specification of the
materials. This basis for specification may be used to prepare specifications related to well-defined
applications. As explained in Clause 5, these specifications will use data blocks 1 to 4 and, if necessary, data
block 5 as a complement, the last-mentioned data block containing the specific requirements in relation to the
application. Fluoroelastomers are specifically excluded.
1.2 Fluoropolymers are long-chain homopolymers and copolymers of fluoromonomers. Fluoropolymers can
be modified with small amounts of different fluoromonomers. In general, provided the polymer is not modified
with more than five percent by mass of modifying fluoromonomer(s), it can be classed as the base polymer.
PVDF is classed as the base polymer when it is modified during polymerization with up to two percent by
mass of additional fluoromonomers in the polymer structure. For PTFE, up to one percent by mass of a
modifying comonomer is the limit for the material to be classed as polytetrafluoroethylene. A general
discussion of members of the fluoropolymer family is included in Annex C. This part of ISO 12086 is
particularly concerned with, but is not limited to, the materials listed in 4.2. The accepted abbreviated term for
each material is included in 4.2.
1.3 The various types of fluoropolymer are differentiated from each other by a classification system based
on the fluoropolymer genus and appropriate levels of the designatory properties, along with information about
basic polymer parameters, intended application or method of processing, important properties, additives,
colorants, fillers and reinforcing materials. Designatory properties for each fluoropolymer are selected from the
general list in 5.4, and those properties to be designated for each fluoropolymer are listed in 5.7 and in
Annexes A and B.
1.4 Provision is made for designation of materials involved in reuse and recycling of the fluoropolymers
covered by this part of ISO 12086. A set of designatory properties is provided for reprocessed PTFE because
of its special requirements. For non-virgin conventional thermoplastic fluoropolymers, the same designatory
properties as used for virgin materials are used with inclusion of the code Z1, Z2 or Z3 in data block 1 as
specified in Table 1.
1.5 It is not intended to imply that materials having the same designation necessarily give the same
performance. The converse should also be emphasized, i.e. materials with different designations may be
suitable for use in the same application. This part of ISO 12086 does not provide engineering data,
performance data or processing conditions which may be required to specify materials for particular end-use
applications (see the discussion on use of data block 5 in Clauses 5 and 7). If such additional properties are
required, they can be determined in accordance with the test methods specified in ISO 12086-2, if suitable.

5 Designation system
5.1 General
The designation system for thermoplastics is based on the following standard pattern:
Designation
Identity block
Individual-item block
International
Description block
Standard
(optional)
Data Data Data Data Data
number
block block block block block
block
1 2 3 4 5

The designation consists of an optional description block, reading “Thermoplastics”, and an identity block
comprising the International Standard number and an individual-item block. For unambiguous designation, the
individual-item block is subdivided into five data blocks comprising the following information:
⎯ Data block 1: Identification of the plastic by its abbreviated term in accordance with ISO 1043-1
(supplemented, if necessary, by the abbreviated term for the fluoropolymer as listed in 4.2
or ASTM D 1600) and information about the composition of the polymer (see 5.2).
⎯ Data block 2: Position 1: Intended application and/or method of processing (see 5.3).
Positions 2 to 8: Important properties, additives and supplementary information (see 5.3).
⎯ Data block 3: Designatory properties (see 5.4 and 5.7).
⎯ Data block 4: Fillers or reinforcing materials designated by letters as given in ISO 1043-2 (supplemented
by the codes listed in Table 20), along with arabic numerals representing the nominal
percentage content by mass (see 5.5).
⎯ Data block 5: Additional details included in this data block will transform the general designation of a
material into a material specification. This may be done by reference to particular
requirements for properties, by reference to a suitable national standard, or both. See
Clause 7 for further discussion and examples.
The first character of the individual-item block shall be a hyphen. The data blocks shall be separated from
each other by a comma.
If a data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,,).
5.2 Data block 1
In this data block, fluoropolymers are identified by the abbreviated term given in ISO 1043-1, followed by a
hyphen and one letter that codes additional information about the polymer as specified in Table 1. See 4.2 for
a list of commonly used fluoropolymers with the abbreviated term for each.

If only one letter is given (e.g. E), its meaning must come from position 1. If information is presented in
positions 2 to 8 and no specific information is given in position 1, a code-letter in position 1 is required. If no
code-letter is appropriate, the letter X shall be inserted in position 1. An alphabetical order is recommended if
more than one code-letter is used in any of positions 2 to 8.
Any indication of an intended application in data block 2 shall be selected carefully. Many materials are
capable of more than one application or method of processing, e.g., extrusion (E) and moulding (M). Such
materials are not special modifications and shall be coded “general use”
