Overview
EN IEC 62321-14:2026, published by CLC, provides a standardized method for the determination of short-chain chlorinated paraffins (SCCPs) and medium-chain chlorinated paraffins (MCCPs) in plastics used in electrotechnical products. This part of the IEC 62321 series focuses on quantitative analysis using gas chromatography-negative chemical ionization-mass spectrometry (GC-NCI-MS). With growing global regulations targeting hazardous substances in electronics, EN IEC 62321-14:2026 supports the consistent, precise detection of SCCPs and MCCPs, facilitating compliance and environmentally responsible manufacturing.
Key Topics
-
Substances Covered:
- SCCPs (short-chain chlorinated paraffins, C10-C13)
- MCCPs (medium-chain chlorinated paraffins, C14-C17)
-
Sample Types:
- Applies to plastics commonly found in electrical and electronic equipment, such as ABS (acrylonitrile butadiene styrene) and PVC (polyvinyl chloride).
-
Analytical Technique:
- Utilizes solvent extraction followed by GC-NCI-MS for high sensitivity and specificity.
- Includes detailed procedures for sample preparation, extraction (including ultrasonic methods), clean-up steps, and calibration.
-
Quality Assurance:
- Incorporates method validation, repeatability, and reproducibility verification based on interlaboratory studies.
- Provides requirements for quality control checks, matrix spike recoveries, and instrument calibration to ensure reliability of results.
-
Regulatory Context:
- Addresses the increasing demands imposed by international environmental and product safety regulations concerning hazardous substances commonly restricted in the electrical and electronic industry.
