WARNING
The use of thermosetting and ThermoPlastic resins in the Chemical Industry has known for over
twenty years a rapid expansion and this experience precedes much of the publishing of national and
international codes applicable in the design, calculation and construction of reinforced plastics
Equipment.
THE French UNION OF CHEMICAL INDUSTRIES (UIC), dedicated to improving the safety of these
Equipment has published in February 1986, revised in 1988 and 1990, a code of good construction
practices (Formerly UIC Safety Book/Specification No. 7), with the collaboration of representatives
from the following companies:
• ATOCHEM / ORKEM / RHONE-POULENC / SOLVAY & Cie
As well as representatives of the General Union of the reinforced Plastic Industry (SGIPA) and the
following Manufacturers:
• SAPS / MURGUE-SEIGLE / CARLIER / CITP / CORD France / HERMEX / SODIPIA / SOVAP /
S3P
This new 2013 edition, while relying on the most recent codes and standards, is established in good
faith and incorporates experience gained in the last 20 years from the following chemical
companies:
• ARKEMA / VENCOREX / RHODIA / SOLVAY SA / TOTAL.
Different stakeholders (Suppliers, Manufacturers, inspection bodies) also contributed to the
development of this revision.
The recommendations of this guideline are the result of the synthesis of the provisions adopted by
the largest, well established chemical companies. They provide a basis beyond which everyone can
choose. They do not replace national and international regulations, and they intend to fully comply
with.
They should not be used as a single document but as a guide which will, in each case, be
completed by the provisions contained in the Purchaser’s specification.
This text can be updated in the future to reflect changes in technology and technical progress.
