Foreword
This European Standard has been prepared by Technical Committee CEN/TC 193 "Adhesives", the secretariat of which is held by AENOR.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest by October 2001.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope
This European Standard specifies a simple test method for the gas-chromatographic determination of free monomer content in polymeric adhesives after specific treatment.
This test method can be used for the determination of acrylic, styrene, vinyl and other unsaturated monomers.
NOTE This method could also be used for the determination of other monomers, if applicable.
2 Normative references
This European Standard 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 Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
EN 923 Adhesives — Terms and definitions
EN 1066 Adhesives — Sampling
EN 1067 Adhesives — Examination and preparation of samples for testing
3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 923 apply.
4 Principle
4.1 Water-borne adhesives
An aliquot of an extract of the water-borne adhesive to be analysed is injected into a gas chromatograph equipped with a capillary column and a linear temperature programmer. The monomers are detected by a Flame Ionisation Detector (FID). Quantification is made by peak area measurement.
4.2 Solvent-borne or solvent-less adhesives
An aliquot of the solvent-borne or solventless adhesive is diluted with a suitable solvent. The solvent shall be able to considerably reduce the viscosity of the adhesive solution as to allow it to be injected into the gas
chromatrograph. The solvent shall not interfere with the monomers to be detected. The diluted solution is analysed as the extract as described in 4.1
5 Safety
Persons using this standard shall be familiar with normal laboratory practice.
This standard does not purport to address all the safety problems, if any, associated with its use.
It is the responsibility of the user to establish safety and health practices and to ensure compliance with any European or national regulatory conditions.
6 Chemicals
All the chemicals used for the test shall be of analytical grade.
