TESTING, EXAMINATION AND ASSESSMENT OF STEEL CONDUITS SUBMITTED ASINDEPENDENT TEST SAMPLES

INTRODUCTION

At the request of Tamco Electrical & Electronics (HK) Ltd the steel conduits detailed below,received on 15 May 2002, were tested and assessed against the requirements of BS 4568:Part1 :1970, BS EN 50086-2-1 :1996 and lEG 60614-2-1 :1993 from 23 May 2002, as indicated onthe following pages of this Report. This request was made in a Fax from client dated 20December 2001. It is emphasized that assessments were not made against the other clausesof the Specification.

I his Report only relates to the actual samples which have been tested and assessed. The,esults obtained do not necessarily relate to samples from the production line and in no wayimply that the performance or quality of the continuing production will be maintained.

I EC 60614-2-1 : 1993

The Galvanised steer conduits met the requirements of those clauses, or parts thereof, of theSpecification against which assessments were made.

The potential variability in, both the items tested and the method of measurement used,. meansthat for measurements close to a specified limit, the level of confidence in a compliancestatement mayor may not be reduced.

Further advice on the specific measurements in this report that may be affected can beobtained from the report authoriser shown on the front cover.
