I – INTRODUCTION

IFTS is a Technical Research Centre, an association which is non-profit making and selffinanced. Because it operates as an interface between university research and filter equipment manufacturers/users, IFTS undertakes activities which help to improve understanding and communication between these fields of expertise.

Furthermore, because of its multi-industry competence, IFTS covers a wide range of industrial systems from chemical to mechanical, nuclear to aeronautical, food to environment in 1986 the Institute started four specific activities to make available to industry efficient tools for greater industrial competitivity. These are the research and development of test methods and equipments, standardisation, certification of its services according to ISO 17025, and certification of filtration products.

This document describes normative and paranormative work undertaken by the Institute at national and international levels.

Also included is a summary of the involvement in multiclient research and round robin tests which IFTS has organised or in which it has participated with other professionals. This is undertaken to validate standards and operating protocols before they are published.
