Introduction
In Europe, according to Regulation (EU) 2018/1513 amending Annex XVII to Regulation (EC) No
1907/2006 (REACH) by Entry 72 [1], (a) clothing or related accessories; (b) textiles other than clothing
which, under normal or reasonably foreseeable conditions of use, come into contact with human skin to
an extent similar to clothing; (c) footwear, are not to be placed on the market after 1 November 2020, if
they contain more than 5 mg/kg of benzene.
This restriction does not apply to: (a) clothing, related accessories or footwear, or parts of clothing,
related accessories or footwear, made exclusively of natural leather, fur or hide; (b) non-textile fasteners
and non-textile decorative attachments; (c) second-hand clothing, related accessories, textiles other than
clothing or footwear; (d) wall-to-wall carpets and textile floor coverings for indoor use, rugs and runners.
It also does not apply to clothing, related accessories, textiles other than clothing, or footwear within the
scope of Regulation (EU) 2016/425 on personal protective equipment or Regulation (EU) 2017/745 on
medical devices. The restriction on textiles other than clothing does not apply to disposable textiles.
“Disposable textiles” means textiles that are designed to be used only once or for a limited time and are
not intended for subsequent use for the same or a similar purpose.
Although the Regulation [1] excludes non-textile fastenings and decorative items, this method is also
suitable for such components.

4 Principle
The sample is cut into small pieces and analysed using a headspace gas chromatograph with mass
selective detector (HS-GC-MS).
5 Reagents
Unless otherwise specified, analytical grade chemicals shall be used.
5.1 Benzene, CAS Registry Number® (CAS RN®) 71-43-2.
5.2 Benzene-d6, CAS RN® 1076-43-3.
5.3 Methanol, CAS RN® 67-56-1.
5.4 Stock solutions
5.4.1 Benzene stock solution
Prepare a benzene stock solution of an appropriate concentration for the HS-GC-MS used (e.g.
c = 1 000 µg/ml) by dissolving benzene (5.1) in methanol (5.3). Store the benzene stock solution at
−18 °C.
EXAMPLE For a benzene stock solution with a concentration of 1 000 µg/ml, 5 ml to 10 ml methanol (5.3) are
added into a 100 ml volumetric flask. (100 ± 0,1) mg of benzene (5.1) are weighed directly in the methanol and filled
to the mark with methanol (5.3).
CAS Registry Number® (CAS RN®) is a trademark of the American Chemical Society (ACS). This information is
given for the convenience of users of this document and does not constitute an endorsement by CEN of the product
named. Equivalent products may be used if they can be shown to lead to the same results.
5.4.2 Internal standard (IS) stock solution
Prepare an IS stock solution of an appropriate concentration for the HS-GC-MS used (e.g. c = 1 000 µg/ml)
by dissolving benzene-d6 (5.2) in methanol (5.3) with an uncertainty of measurement of 0,1 mg. Store
the IS stock solution at −18 °C.
EXAMPLE For an IS stock solution with a concentration of 1 000 µg/ml, 5 ml to 10 ml methanol (5.3) are added
into a 100 ml volumetric flask. (100 ± 0,1) mg of benzene-d6 (5.2) is weighed directly into the flask and filled to the
mark with methanol (5.3). The IS stock solution is stored at −18 °C.
5.5 Internal standard (IS) working solution
Dilute the IS stock solution (5.4.2) 1 to 10 with methanol (5.3) to obtain the IS working solution (e.g.
c = 100 µg/ml).
EXAMPLE 100 µl IS stock solution is diluted to a total volume of 1 000 µl with 900 µl methanol (5.3).
5.6 Calibration solutions
Prepare at least three calibration solutions of appropriate concentrations for your HS-GC-MS.
EXAMPLE About 5 ml to 10 ml methanol (5.3) is filled each into three different 100 ml volumetric flasks. An
appropriate amount of benzene stock solution (5.4.1) and IS stock solution (5.4.2) are added into the flask (see
Table 1) and filled to the mark with methanol (5.3).
