1.1 This part of ISO 14910 establishes a system of designation for thermoplastic polyester/ester and
polyether/ester elastomers, which may be used as the basis for specifications.
1.2 The types of thermoplastic polyester/ester and polyether/ester elastomer are differentiated from each other by
a classification system based on appropriate levels of the designatory properties
a) hardness;
b) melting temperature;
c) tensile/flexural modulus of elasticity;
and on information about the intended application and/or method of processing, important properties, additives,
colourants, fillers and reinforcing materials.
1.3 This part of ISO 14910 is applicable to all thermoplastic polyester/ester and polyether/ester elastomers.
It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by
colourants, fillers or other additives.
1.4 It is not intended to imply that materials having the same designation give necessarily the same performance.
This part of ISO 14910 does not provide engineering data, performance data or data on processing conditions
which may be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they shall be determined in accordance with the test methods specified in
part 2 of this International Standard, if suitable.
1.5 In order to specify a thermoplastic polyester/ester or polyether/ester material for a particular application or to
ensure reproducible processing, additional requirements may be given in data block 5 (see clause 3, introductory
paragraph).
In diesem Teil von ISO 14910 ist ein Bezeichnungssystem für thermoplastische Polyester/Ester- und Polyether/Ester-Elastomer-Formmassen festgelegt, das als Grundlage für Spezifikationen dienen kann. Die Polyester/Ester- und Polyether/Ester-Elastomer-Formmasse-Typen werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften a) Härte, b) Schmelztemperatur, c) Zug-/Biege-Elastizitätsmodul und Informationen über vorgesehene Anwendung und/oder Verarbeitungsverfahren, wichtige Eigenschaften, Additive und Farbstoffe, Füll- und Verstärkungsstoffe beruht.
