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 of
standardisation and Quality assurance with the aim of facilitating the faster movement of goods
and services within the region so as to enhance expansion of intra-COMESA trade and industrial
expansion.
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 Trade
that are normally encountered when goods and services are exchanged between COMESA
Member States due to differences in technical requirements. Harmonized COMESA Standards
are also expected to result into benefits such as greater industrial productivity and
competitiveness, increased agricultural production and food security, a more rational exploitation
of natural resources among others.
COMESA Standards are developed by the COMESA experts on standards representing the
National Standards Bodies and other stakeholders within the region in accordance with
international procedures and practices. Standards are approved by circulating Final Draft
Harmonized Standards (FDHS) to all member states for a one Month vote. The assumption is
that all contentious issues would have been resolved during the previous stages or that an
international or regional standard being adopted has been subjected through a development
process consistent with accepted international practice.
COMESA Standards are subject to review, to keep pace with technological advances. Users of
the COMESA Harmonized Standards are therefore expected to ensure that they always have the
latest version of the standards they are implementing.
This COMESA standard is technically identical to IEC 60050-603:1986, International
Electrotechnical Vocabulary — Generation, transmission and distribution of electricity — Power
system planning and management
A COMESA Harmonized Standard does not purport to include all necessary provisions of a contract.
Users are responsible for its correct application.
