Technical committee of the Other Fluids


Chairman: interim Claude DELARUE (GFC)
Vice Chairman: Mr. Ralf Strauss (BASF-D)

Since 1980, a working group of the GFC in the CTLM (engines lubricants technical committee), has developed methods of testing the cooling liquids. A collection was published in 1990: GFC-L-100-A-90, “coolant for Internal-Combustion engines”, containing 8 methods at the "approved" status. Their repeatability and reproducibility is perfectly defined, these methods were transmitted to the BNA (Automotive standardization office in AFNOR) and contributed greatly to the development of the first French standard on the cooling liquids: NF-R-15-601.

In 1991, the technical Committee on other fluids was created and took over the activity of the Working Group of the CTLM by expanding beyond the cooling liquids. Integrated in 1996 within the CEC as Fluids Special Group (FSG), the CTAF continued its work in the context of the ECTC (Engine Coolants Technical Committee) until 2001. Following the meeting of 20 April 2001, the ECTC had no longer enough dynamics to continue its work within the new CEC and the group returned to the GFC in retaining its European members (French, German, Belgian, Spanish, English,...).

Today, the CTAF has 15 participants, and its members meet 2-3 times a year. This number is growing since 2001, and the CTAF remains a working group with a European vocation. The CTAF activity focuses on the cooling liquids. To date, some of the methods of 1990 have already been reworked, and others will be revised soon. In addition new methods, initiated from the work of the GFC.

  • Create or develop, on the theme of automotive fluids (excluding oils, greases and fuels), French testing methods, which may be introduced at European level.
  • Enable, through regular contacts, technical discussions between manufacturers, chemical industries, fluid manufacturers and users.
  • Promote methods validated with the standardisation bodies (AFNOR, BNA,...).
  • Ensure the relevance and sustainability of methods validated through the monitoring committees and the periodic revisions.


The main topics are:

  • Physico-chemical determination
  • Performance Evaluation
  • Compatibility testing
  • Contribution through BNA to update the AFNOR standard NF-R-15-601 on coolants

Creation of 2 working groups in 2005

  • Washing liquid for windscreen: pilot by interim: Claude DELARUE  (closed in 2019)
  • Washing product for vehicles: pilot by Emilie REY (closed in 2011)

Creation of a Working Group in 2011

  • Brake fluid - pilot by Ms. Anabelle CHARTIER (closed in 2015) ISO activity followed


    There are currently 14 valid methods proposed in the section 'Methods' of this site
