Описание (английский):

ISO 16565:2013 specifies the methods to be used to determine the content of 5 ethylidenenorbornene (ENB) or dicyclopentadiene (DCPD) in ethylene-propylene-diene (EPDM) terpolymers in the 0,1 % to 10 % range. ENB and DCPD are dienes introduced into ethylene-propylene rubbers to generate specific cure properties. Since high precision for diene content determination is important, a Fourier transform infrared spectroscopic (FT IR) method is utilized.

Overview

ISO 16565:2013 specifies a Fourier transform infrared (FT‑IR) method for determining the content of 5‑ethylidenenorbornene (ENB) or dicyclopentadiene (DCPD) in ethylene‑propylene‑diene (EPDM) terpolymers. The standard covers quantitative determination in the 0.1 % to 10 % diene mass‑fraction range. ENB and DCPD are dienes added to EPDM to tailor cure behavior; accurate diene-content measurement is essential for quality control and formulation consistency.

Key topics and requirements

Analytical principle: FT‑IR measurement using the second derivative of the absorbance spectrum, ratioed to an internal thickness gauge and calibrated against known standards.

Key spectral regions: ENB quantified from the absorbance near 1681–1690 cm⁻¹ (exocyclic double bond); DCPD from 1605–1610 cm⁻¹ (monocyclic double bond).

Specimen preparation: Compression-moulded films between PTFE‑coated sheets or salt‑plate mounts for liquids; specific mass and temperature/pressure conditions are given for reproducible films.

Instrumentation requirements: FT‑IR spectrometer with resolution 2 cm⁻¹, DTGS or MCT detector, capability for spectral accumulation/averaging and subtraction; dry‑gas purge or specimen shuttle recommended to minimize water vapour interference.

Calibration: Linear calibration from multiple standards (recommended at several points across 0–10 %), with primary standards often established by proton NMR (H‑NMR) or other qualified methods.

Film thickness determination: Automated thickness gauge based on isooptic and anchor points in the spectrum; normalization of spectra to one optical density unit before quantification.

Special cases: Oil‑extended EPDM requires oil extraction before diene determination; Annex A describes spectral subtraction of water vapour when purge is insufficient.

Precision and reporting: The standard includes procedures to assess method precision and the required test‑report elements.

Practical applications and users

ISO 16565 is used where precise diene quantification in EPDM is required:

Quality control laboratories in rubber and polymer manufacturing for batch release and supplier verification.

Formulation and R&D teams optimizing cure systems and performance attributes of EPDM terpolymers.

Contract testing and accreditation labs performing standardized, traceable ENB/DCPD analysis.

Regulatory and compliance contexts where documented standard methods are required.

Keywords: ISO 16565, ENB, DCPD, EPDM, FT‑IR, diene content, rubber testing, terpolymer analysis, Fourier transform infrared.
