ISO 284:2012 specifies the maximum electrical resistance of a conveyor belt and the corresponding test method. The test is intended to ensure that the belt is sufficiently conductive to avoid the accumulation of electrical static charge which can be developed during service use. ISO 284:2012 is not suitable or applicable to light conveyor belts as described in ISO 21183-1, the static electrical properties of which are measured by ISO 21178.

This document 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. This document 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. This document is not applicable to conveyor belts which 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 this document. 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 prEN 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 1523-1.

This document specifies the security requirements for the design of checkout furniture in self-service stores, regardless of the size of the store. Safety requirements apply to both the operator and the public. This document applies to all types of checkout furniture equipped with electrically powered conveyor(s). It does not deal with computer equipment related to cash register furniture. This document covers all significant hazardous phenomena, situations or events, with the exception of..., which are relevant to cash registers when used normally and when they are subject to reasonably foreseeable misuse by the manufacturer. (Risks covered: mechanical, electrical (excluding IT, including controls), electromagnetic compatibility (EMC), ergonomics (refer to standard NF X 35-701 which must evolve into a European standard), hygiene (food contact, REACH, materials, cleaning products), recyclability, fire, noise).
