What is BS 6907-3 - Electrical installations for open-cast mines and quarries about?
BS 6907-3 gives recommendations for good practice for the safe and efficient installation and use of electrical equipment and ancillaries.
For winning, stacking and processing machinery, pumps and low signal level and communications systems, exemptions from these recommendations and supplementary recommendations are given in BS 6907-4, which should, therefore, be read in conjunction with BS 6907-3.
BS 6907-3 applies to the installation and operation of electrical apparatus and systems associated with outdoor sites under heavy conditions, including open-cast mines, quarries, stockpiles, etc. It applies particularly to electrical apparatus and systems used for the following:
- Winning, stacking and primary processing machinery
- Secondary processing machinery
- Conveyor systems
- Pumping and water supply systems
- Movable railway systems
- Control, signal, supervisory, and communication systems
Note: A glossary of terms used in BS 6907-3 is given in BS 6907-1.
Who is BS 6907-3 - Electrical installations for open-cast mines and quarries for?
BS 6907-3 on electrical installations for open-cast mines and quarries is useful for:
- The mining and quarrying industry
- Electrical equipment manufacturers
- Installation teams of electrical equipment
- Quality control authorities
- Health and safety authorities
Why should you use BS 6907-3 - Electrical installations for open-cast mines and quarries?
BS 6907-3 has been prepared under the direction of the Mining and Quarrying Requisites Standards Committee. BS 6907 is based on the International Electrotechnical Commission’s publication IEC 621 “Electrical installations for outdoor sites under heavy conditions (including open-cast mines and quarries)” and, like that publication, is published in Parts as follows.
- Part 1: Glossary
- Part 2: General recommendations for protection against direct contact and electric shock
- Part 3: Recommendations for equipment and ancillaries
- Part 4: Recommendations for winning, stacking and processing machinery, pumps and low signal level and communications systems
- Part 5: Recommendations for operation
BS 6907 sets out the guiding principles for the installation and operation of electrical equipment so as to ensure the safety of persons, livestock, property and proper functioning of the plant.
Note: BS 6907 does not cover temporary and provisional places of work in the open, such as building sites and earth moving sites, unless the equipment used is similar to that used in surface mining applications. It takes account of British practice, electrical regulations and law and thereby differs in several respects from the IEC publication. Both cover a subject not previously the subject of an international standard or a British Standard.
