What is BS EN 61057- Insulating aerial devices for mounting on a chassis about?
BS EN 61057 is applicable to insulating aerial devices for mounting on a chassis, to be used for live work on electrical installations at nominal voltages above 1 000V r.m.s. AC in the range 45 Hz to 65 Hz and 1 500V DC.
The primary purpose of an aerial device is for the work positioning of personnel. Other devices, such as jibs, may be fitted in order to assist the operator in performing the work.
BS EN 61057 also includes requirements and tests for the parts of the chassis influencing the performance of the insulating aerial devices to be used for live working.
The products designed and manufactured according to BS EN 61057 contribute to the safety of users, provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.
Note 1: In Europe, EN 280 instead of ISO 16368 is often used as a reference for complementary requirements.
Note 2: Any requirements that are in conflict with or are meant to be complementary to ISO 16368 are delineated herein. Radial boom (digger) derricks are not covered by BS EN 61057.
Who is BS EN 61057- Insulating aerial devices for mounting on a chassis for?
BS EN 61057 on Insulating aerial devices for mounting on a chassis is useful for:
- Aerial device manufacturers
- Aerial equipment suppliers
- Electricians
- Quality assessors
Why should you use BS EN 61057- Insulating aerial devices for mounting on a chassis?
BS EN 61057 covers insulating aerial devices for use at temperatures between −25 °C and +55 °C, where aerial devices are for use in unusual atmospheric conditions (for example, higher or lower temperatures), other considerations may be appropriate and will be identified by the manufacturer both in the markings and instructions for use.
The products covered by BS EN 61057 are primarily intended to be used for live working or for work within the live working zone. It recognizes that a user may specify a product, or products complying with BS EN 61057 where there is a risk of accidental contact with live (energized) part(s). In such circumstances, users are reminded that national or local regulations regarding maintaining Minimum Approach Distances to live parts or those obtained from IEC 61472 are to be applied. Annex A of BS EN 61057 gives advice and information.
The product covered by BS EN 61057 may have an impact on the environment during some or all stages of its life cycle. These impacts can range from slight to significant, be short-term or long-term, and occur at the global, regional or local level.
Compliance with insulation techniques outlined in BS EN 61057 can help users increase safety of persons live working.
