Single source EMC testing service launched
Sira Test and Certification has formed an alliance to offer a one-stop shop facility for customers who are manufacturing electrical equipment for use in hazardous areas.
The dangers of siting electrical apparatus in areas where explosive mixtures of flammable materials and air could occur are covered by this legislation.
Many factories, plants and sites are already classifying their hazardous areas and limiting and restricting the use of equipment in those potentially explosive atmospheres in compliance with the Health and Safety etc at Work Act.
Already, many organisations working in the petrochemical industry, in mining, chemicals and power stations, and in some pharmaceutical and water industry environments are accustomed to zoning their areas of work in accordance with this legislation.

Useful free wallchart explains Atex directives
Sira Test and Certification has produced an updated version of its 'Ex Directory' wallchart intended as an information source for both ATEX 100a Directive 94/9/EC and ATEX 137 Directive 1999/92/EC
Sira Test and Certification offers a full hazardous area classification service from its Hazardous Area Centre in Chester.
The service is intended to allow customers to utilise Sira's expertise in the ATEX 137 directive by commissioning support and project management to help with their hazardous area classification.
The classification of hazardous areas is a multi-stage project, taking into account a large number of factors and requiring both expertise and interpretation of the various Codes of Practice, as well as a number of extremely in-depth calculations relating to each individual site.
Sira offers its customers a full service to help the employer meet the legal obligations, including the assessment of their site's Sources of Hazard and likelihood of sources of ignition, classification of the area into zones and marking all points of entry, as well as producing and maintaining documentation.
Sira offers customers the support required to zone their sites, by area.
This then leads to a clear classification of areas into: Zones 0 and 20 - potentially explosive atmosphere is continuously present or for long periods.
Zones 1 and 21 - potentially explosive atmosphere is likely to occur in normal operation.
Zones 2 and 22 - potentially explosive atmosphere is unlikely to occur and will exist for only a short time.
The process of area classification requires full analysis of properties of materials, of the equipment and conditions and site layout, as well as ventilation.
Sira's capabilities extend to assignation of a team, meetings, reviews, calculations of hazards and full area classification review.
