Overview
EN 12766-3:2004 (CEN) specifies a standardized test method for the determination and quantification of polychlorinated terphenyls (PCT) and polychlorinated benzyl toluenes (PCBT) in petroleum products and related materials. The method uses a defined gas chromatographic (GC) separation followed by detection with an electron capture detector (ECD). Quantification is described for PCT Aroclor 5442, PCT Aroclor 5460 and PCBT (Ugilec 141). This Part 3 extends EN 12766 Parts 1 and 2 to enable combined assessment of PCBs and related chlorinated products in accordance with EC Directive 96/59/EC.
Key topics and requirements
- Analytical technique: Gas chromatography with an electron capture detector (GC–ECD) using a specified separation procedure.
- Target analytes: Polychlorinated terphenyls (PCT) and polychlorinated benzyl toluenes (PCBT); quantification for Aroclor 5442, Aroclor 5460 and Ugilec 141.
- Scope of materials: Unused, used and treated petroleum products (including synthetic lubricating oils), recovered petroleum products from wastes, and mixtures containing vegetable oils.
- Quantification limits (minimum concentrations): concentrations above which the method applies as given in the standard:
- PCT: 10 mg/kg
- PCBT: 5 mg/kg
- (Complementary values from EN 12766-2 for PCBs: 8 mg/kg Method A, 4 mg/kg Method B; combined “total PCB and related products” ≈ 25 mg/kg as a best estimate)
- Regulatory linkage: Designed to support total PCB determinations required by Articles 2–4 of EC Directive 96/59/EC by summing PCB (EN 12766‑2) and PCT/PCBT (EN 12766‑3) results.
- User responsibility: Laboratories must demonstrate analyses are carried out within a valid calibrated concentration range; field conditions can affect applicable ranges.
Applications
- Environmental and regulatory testing: Compliance testing for PCB-related contaminant limits under EC directives and national regulations.
- Waste management & recycling: Screening and quantification of PCT/PCBT in recovered oils before re-use, disposal or treatment.
- Industrial quality control: Monitoring lubricants, industrial oils and feedstocks for chlorinated contaminant content.
- Contract testing laboratories: Routine analysis for clients in petrochemical, lubricant manufacture, waste treatment and environmental consultancy sectors.
