countries are bound to announce this European Prestandard : Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland and the United Kingdom.

1 Scope
This European Prestandard specifies a method for the determination of single volatile organic compounds (VOC's)
and of the total amount of volatile organic compounds in the exhaust air of an emission test chamber after
application of an adhesive (TVOC ). The method is based on use of a solid sorbent with subsequent
ENV13999
desorption and gas chromatographic analysis. The method is applicable to measurement of non-polar and slightly
polar VOC's.
2 Normative references
This European Prestandard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Prestandard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

methods.
ENV 13999-1, Adhesives - Short term method for measuring the emission properties of low-solvent or solvent-free
adhesives after application - Part 1: General procedure.
ENV 13419-1, Building products - Determination of the emission of volatile organic compounds - Part 1: Emission

3 Principle
An emission test chamber as described in ENV 13999-1 or in ENV 13419-1 shall be used.
A sufficient volume of test chamber air is drawn with an appropriate flow through one (or more) sorbent tubes in
series containing a solid sorbent. Volatile organic compounds (VOC's) are retained by the sorbent tube, which is
subsequently analysed in the laboratory. The VOC's are desorbed from the sampling tube and transferred by a flow
of inert carrier gas into a capillary gas chromatograph coupled to a mass spectrometric detector (MS) and to a
flame ionisation detector (FID) or only to a mass spectrometric detector.
4 Safety
This Prestandard does not purport to address all of the safety concerns, if any associated with its use. The user of
this Prestandard should be familiar with common laboratory practice including general safety measures. It is the
responsibility of the user of this Prestandard to establish appropriate safety and health practices and determine the
applicability of regulatory limitations prior to use.

5 Reagents and materials
5.1 Volatile organic compounds for calibration, of gas chromatographic grade.
5.2 Methanol, of gas chromatographic grade.
5.3 Sorbent material
1)
For general purpose Tenax TA [1] (poly(2,6-diphenyl-p-phenylene oxide)), particle size (0,18 to 0,25) mm i.e. (60
to 80) mesh shall be used.
1)
For the determination of very volatile carcinogenic organic compounds (e.g. vinylchloride) Chromosorb 106
(polystyrene) or equivalent sorbent materials as described in EN ISO 16017-1 shall be used.
5.4 Carrier gas
Helium, argon or nitrogen with a purity 99,999% or better.
6 Apparatus
6.1 Sorbent tubes
Sorbent tubes, made from stainless steel or glass, that can be filled with at least 200 mg of Tenax TA sorbent (5.3)
are used. For example tubes with 6 mm external diameter, 5 mm internal diameter and 90 mm long fulfil the
requirement and are used in many commercial thermal desorbing devices.
NOTE It is recommended to use unsilanised glass wool or other suitable mechanism, e.g. stainless steel frit to retain the
sorbent in the tube and metal screw caps and polytetrafluoroethylene (PTFE) ferrules for closing the sorbent tube.
1)
Fill Chromosorb or equivalent tubes as described in EN ISO 16017-1.
6.2 Sorbent tube unions
Two sorbent tubes may be connected in series during sampling with metal screw cap couplings with PTFE ferrules.
6.3 Syringes
A precision 10 μl liquid syringe readable to 0,1 μl.
6.4 Sampling pump
The pump shall fulfil the requirements of EN 1232 or equivalent.
6.5 Tubing
PE (polythene) or PTFE tubing of appropriate diameter to ensure a leak-proof fit to both pump and sample tube.
Sampling tubes shall not be used with plastic tubing other than PTFE upstream of the sorbent to avoid interference
from contaminants.
6.6 Flow meter calibrator
Bubble meter or other appropriate suitable device for gas flow calibration.
1) Chromosorb 106 and Tenax TA are an example of suitable products available commercially. This information is given for
the convenience of users of this European Prestandard and does not constitute an endorsement by CEN of this product.

6.7 Gas chromatograph
A capillary gas chromatograph coupled to a mass spectrometric detector and to a flame ionisation detector or only
to a mass spectrometric detector shall be used in accordance with EN ISO 16017-1.
6.8 Thermal desorption apparatus
Apparatus for two-stage thermal desorption of sorbent tubes and transfer of desorbed vapours via an inert gas flow
into a gas chromatograph is required. A typical apparatus contains a mechanism for holding the tubes to be
desorbed whilst they are heated and purged simultaneously with inert carrier gas. The desorption temperature and
time is adjustable, as is the carrier gas flow rate. The apparatus may also incorporate additional features, such as
autom
