Overview
prEN 17937 is a forthcoming European standard developed by CEN/TC 462 that specifies an analytical method for determining the total content of eight regulated polycyclic aromatic hydrocarbons (PAHs) in plastic and rubber articles. These products are supplied to the general public and intended for direct contact with human skin or the oral cavity. The method employs gas chromatography coupled with mass spectrometry (GC-MS) to accurately detect PAHs down to levels of 0.1 mg/kg for plastics and 0.2 mg/kg for rubber materials.
This standard supports the enforcement of EU REACH Annex XVII restrictions (Entry 50) on carcinogenic PAHs in consumer items, helping manufacturers, regulators, and testing laboratories ensure compliance with health and safety requirements.
Key Topics
Scope and Substance List:
prEN 17937 targets eight specific PAHs-Benzo[a]pyrene, Benzo[e]pyrene, Benzo[a]anthracene, Chrysene, Benzo[b]fluoranthene, Benzo[j]fluoranthene, Benzo[k]fluoranthene, and Dibenzo[a,h]anthracene. The method allows for analysis of other PAHs if proven suitable.Analytical Principle:
The procedure involves extracting PAHs from representative samples of plastic or rubber using solvents such as toluene or n-heptane. Extraction can be performed by Soxhlet, automated Soxhlet (Randall), or ultrasonic bath methods. After extraction, samples undergo cleanup to remove interferences before GC-MS analysis, where PAHs are identified and quantified using internal standards.Reagents and Equipment:
The protocol requires high-purity solvents and PAH standard solutions, at least three internal deuterated standards matching ring systems, and specialized GC-MS instrumentation capable of electron ionization and single ion monitoring or tandem MS/MS.Sample Preparation:
Samples representing portions in direct skin or oral contact must be homogenized into small fragments (~2-3 mm). Liquids, coatings, powders, and granulates have specific preparatory guidelines to maintain representative, unaltered samples for analysis.Calibration and Quantification:
Calibration curves use native PAH standards, while internal standards ensure accuracy and consistency with GC-MS measurements. Storage and handling conditions for reagents and samples are defined to maintain stability.Safety Notice:
PAHs are hazardous substances with carcinogenic and teratogenic properties. Appropriate laboratory safety and handling precautions are mandatory.
Applications
Regulatory Compliance:
prEN 17937 is essential for manufacturers and importers of consumer rubber and plastic products to verify compliance with EU restrictions on PAHs, particularly for toys, personal care items, and other articles with prolonged skin or oral cavity contact.Market Surveillance:
Testing laboratories can adopt this harmonized GC-MS method to conduct reliable surveillance and enforcement testing, supporting public health protection and consumer safety.Quality Control:
Manufacturers can integrate this analytical procedure into routine quality control measures to monitor PAH levels during production, minimizing regulatory risks.Research and Development:
The standard also provides a validated analytical approach for studying the migration, degradation, or presence of PAHs in new polymer formulations intended for consumer use.

European foreword
This document (prEN 17937:2023) has been prepared by Technical Committee CEN/TC 462 “Regulated
chemicals in products”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
Introduction
In December 2013, based on a report established in 2010 by the German authorities, the European
Commission amended the REACH Annex XVII through the Regulation (EU) No. 1272/2013, with amend
entry 50, with the addition of paragraphs 5 and 6. This Regulation addresses and restricts the use of
eight PAHs (Polycyclic Aromatic Hydrocarbons) in rubber and plastic articles supplied to the general
public that come into direct as well as prolonged contact or short-term repetitive contact with human
skin or the oral cavity, under normal or reasonably foreseeable conditions of use.
To support the enforcement of this restriction the European Commission requested the European
Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization
(CENELEC) to draft harmonized standards for the analytical determination of the individual
concentrations of the 8 carcinogenic PAHs, listed in entry 50 of Annex XVII to Regulation (EC) No.
1907/2006 (REACH), in plastic and rubber components (see standardization request M/556).
A Technical Board Working Group 13 "PAHs" (CEN-CLC/BT/WG 13) established by CEN-CENELEC had
to investigate that request through a scoping study which had to identify if any existing methods to
determine the total content for PAHs in rubber and plastic articles exist but also if any spectroscopic
methods could assist Market Surveillance Authorities in performing non-destructive screening tests.
The result of the scoping study based on an up to date literature review concluded the need to develop
a harmonized standard to support (EU) No. 1272/2013 legislation, which is developed hereafter.
1 Scope
This document specifies a method to determine the total content of the 8 regulated polycyclic aromatic
hydrocarbons (PAHs), see Table 1, in plastic and rubber articles by using GC-MS allowing detection at

4 Principle
The test specimen is extracted using toluene (or n-heptane) using a Soxhlet or Randall (automated
Soxhlet) extraction or ultrasonic bath extraction method. The extract is concentrated and interfering
compounds are removed by a clean-up method. An aliquot is then analysed using a gas chromatograph
with mass selective detector (GC-MS).
PAHs are identified and quantified with GC-MS by comparison of relative retention times and relative
peak heights (or peak areas) with respect to internal standards added.
