This European Standard was approved by CEN on 19 May 2005.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Central Secretariat or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official
versions.

Foreword
This document (EN 14666:2005) has been prepared by Technical Committee CEN/TC 276 “Surface active agents”,
the secretariat of which is held by AFNOR.
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by endorsement, at the latest by December 2005, and conflicting national standards shall be withdrawn at the latest
by December 2005.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
1 Scope
This European Standard specifies a method for the determination of tetraacetyl ethylene diamine (TAED) content
greater than or equal to 25 g/100 g in granules.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
ISO 607, Surface active agents and detergents – Methods of sample division.
3 Principle
The TAED granules are dissolved in acetonitrile, the internal standard is added to this solution and finally it is
injected to a gas chromatograph. A flame ionisation detector is used for detection. The results are calculated from
the peak areas taking into account the response factors that are determined previously.
4 Reagents
During the analysis, unless otherwise specified, use only reagents of recognized analytical grade that have been
checked in advance as not interfering with the analytical results.
