Foreword

The Common Market for Eastern and Southern Africa (COMESA) was established in 1994 as a

regional economic grouping consisting of 20 member states after signing the co-operation Treaty.In Chapter 15 of the COMESA Treaty, Member States agreed to co-operate on matters ofstandardisation and Quality assurance with the aim of facilitating the faster movement of goodsand services within the region so as to enhance expansion of intra-COMESA trade and industrialexpansion.

Co-operation in standardisation is expected to result into having uniformly harmonised standards.Harmonisation of standards within the region is expected to reduce Technical Barriers to Tradethat are normally encountered when goods and services are exchanged between COMESAMember States due to differences in technical requirements. Harmonized COMESA Standardsare also expected to result into benefits such as greater industrial productivity andcompetitiveness, increased agricultural production and food security, a more rational exploitationof natural resources among others.

COMESA Standards are developed by the COMESA experts on standards representing theNational Standards Bodies and other stakeholders within the region in accordance withinternational procedures and practices. Standards are approved by circulating Final DraftHarmonized Standards (FDHS) to all member states for a one Month vote. The assumption isthat all contentious issues would have been resolved during the previous stages or that aninternational or regional standard being adopted has been subjected through a developmentprocess consistent with accepted international practice.

COMESA Standards are subject to review, to keep pace with technological advances. Users ofthe COMESA Harmonized Standards are therefore expected to ensure that they always have thelatest version of the standards they are implementing.

This COMESA standard is technically identical to IEC 60076-2:1993, Power transformers ⎯ Part2: Temperature rise

A COMESA Harmonized Standard does not purport to include all necessary provisions of a contract.

Users are responsible for its correct application.
