What is BS EN 12882- Electrical and flammability safety requirements of conveyor belts about?
BS EN 12882 specifies electrical and flammability safety requirements for general purpose conveyor belts not intended for use in underground installations and a means of categorizing conveyor belts in terms of the level of safety sought in their end-use application. BS EN 12882 does not provide electrical safety requirements for volume resistance which may be measured by the methods in EN ISO 21178, and which is relevant to some types of light conveyor belts.
BS EN 12882 is not applicable to conveyor belts that are manufactured before the date of publication of this document by CEN.
Note 1: Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by BS EN 12882. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC, this being covered in EN 14973.
Note 2: EN 12882 is not a product standard but is intended to help users of conveyor belts to select the required electrical and flammability safety properties needed following a suitable risk assessment. No requirements are, therefore, included for marking, information to be supplied, etc., these matters being covered in relevant product standards such as EN ISO 14890 and EN ISO 15236-1.
Who is BS EN 12882- Electrical and flammability safety requirements of conveyor belts for?
BS EN 12882 on electrical and flammability safety requirements of conveyor belts is useful for:
- Spacecraft and space products manufacturers
- Aerospace products manufacturers
- Testing agencies involved in the inspection of spacecraft and aerospace products
- Quality control personnel for spacecraft products
- Aeronautical engineers
- Space researchers
Why should you use BS EN 12882- Electrical and flammability safety requirements of conveyor belts?
The machinery concerned and the extent to which hazards, hazardous situations, and events are covered are indicated in the scope of BS EN 12882.
During the preparation of BS EN 12882, the hazards which have been identified as being directly related to the use of conveyor belts are:
- Hazards associated with the discharge of static electrical energy
- Hazards associated with the impingement of small naked flames on the cover and/or carcass of a conveyor belt at res
- Hazards caused by the stalling of a conveyor belt and the continued operation of the driving mechanism causing localized heating of the conveyor belt through contact with the driving drum or cylinder or some other source of frictional heat
- Hazards caused by the propagation of a flame along a belt that has been exposed to a relatively high energy source such as a fire.
The risk or probable rate of occurrence of these hazards and the degree of harm they can cause will vary depending upon the circumstances of the application or site of application, which are many and varied. Depending on the individual end-use requirement, these other factors can affect the category of belt selected and additional safety precautions may need to be employed.
BS EN 12882 is therefore designed to enable the user to select the category of conveyor belt most suited to the particular circumstances of the application.
