Full title and description

DIN EN ISO 584:1998-03 — Plastics — Unsaturated polyester resins — Determination of reactivity at 80 °C (conventional method). This is the German national adoption of EN ISO 584:1997, which implements ISO 584:1982 for measuring the reactivity of unsaturated polyester resins under defined thermal conditions.

Abstract

Specifies a conventional test method to determine the reactivity of unsaturated polyester resins by measuring the maximum temperature reached by a resin/catalyst mixture heated in a water bath at 80 °C and by recording the time taken for the mixture temperature to rise from 65 °C to the peak (and, where applicable, the time from 65 °C to 90 °C). The procedure defines detailed test conditions because results are highly sensitive to test setup; it is intended for comparison of resins of similar type.

Scope

Provides a standardized laboratory procedure to characterise the curing/reactivity behaviour of unsaturated polyester resins under a defined isothermal/pre-heated-water-bath environment (80 °C). The method yields parameters — peak temperature and characteristic rise-times — that allow comparison between similar resin formulations and assist in quality control, formulation development and process planning. It is not intended to predict all aspects of processing behaviour but to give reproducible comparative data when the specified conditions are followed.

Key topics and requirements

• Test temperature: water-bath at 80 °C (specified isothermal arrangement and sample handling).
• Primary measurements: maximum temperature reached (Tmax) and time for temperature to rise from 65 °C to Tmax; where Tmax > 90 °C, time from 65 °C to 90 °C is also recorded.
• Detailed specification of sample preparation, catalyst addition, vessel geometry and thermocouple placement because results depend strongly on test conditions.
• Intended use: comparative evaluation of similar unsaturated polyester resin formulations and routine quality checks rather than absolute prediction of all processing outcomes.

Typical use and users

Used by resin manufacturers, formulation chemists, polymer testing laboratories, quality-control departments and research groups working with unsaturated polyester systems. Typical applications include batch-to-batch QC, comparative formulation screening, and process parameter guidance for curing/polymerisation operations.

FAQ

Q: What is this standard?

A: DIN EN ISO 584:1998-03 is the German national adoption of the EN/ISO test method (ISO 584:1982) that defines a conventional laboratory procedure for measuring the reactivity of unsaturated polyester resins at an 80 °C water-bath condition.

Q: What does it cover?

A: It covers the apparatus, sample preparation and step-by-step procedure to record the maximum temperature reached by a resin/catalyst mixture at 80 °C and the characteristic temperature-rise times (65 °C → Tmax and, if relevant, 65 °C → 90 °C), with emphasis on strict test conditions to obtain reproducible comparative results.

Q: Who typically uses it?

A: Resin producers, QC and analytical laboratories, formulation chemists and researchers working on unsaturated polyester systems who need a standardized comparative measure of curing/reactivity.

Q: Is it current or superseded?

A: ISO 584 (the underlying international document, first published 1982) is listed on the ISO record and has been subject to periodic confirmation; the DIN adoption (DIN EN ISO 584:1998) is documented in national catalogues as the 1998 German version of the EN/ISO text. Users should check the latest national catalogues or the ISO database for any subsequent withdrawals, revisions or newer methods before use.

Q: Is it part of a series?

A: It is a stand‑alone ISO test method within the plastics testing area (ICS 83.080.10). It is not numbered as a multi‑part ISO series but is referenced alongside other plastics test standards and handbook entries for resin characterisation.

Q: What are the key keywords?

A: Unsaturated polyester resin, reactivity, cure test, Tmax, isothermal 80 °C method, comparative resin evaluation, DIN EN ISO 584.
