Electromagnetic compatibility — Product family standard for lifts, escalators and moving walks — Immunity
|Publication Date:||1 June 2009|
|ICS Code (Lifts. Escalators):||91.140.90|
This International Standard specifies the immunity performance criteria and test levels for apparatus used in lifts, escalators and moving walks, which are intended to be permanently installed in buildings, including the basic safety requirements in regard to their EMC environment. These levels represent essential EMC requirements.
This International Standard refers to normal EMC conditions as existing in residential, office and industrial buildings, but does not cover more severe EMC environments such as
- radio transmitter stations,
- railways and metros,
- heavy industrial plants,
- electricity power stations,
which need additional investigations.
It is assumed that no ports connected to safety circuit only are rated at currents greater than 100 amps.
It is assumed that mobile telephones and radio transmitters used at frequencies and power of that stated in Table 1 are not placed within 200 mm distance from safety circuit(s).
This International Standard addresses commonly known EMC related hazards and hazardous situations relevant to lifts, escalators and moving walks when they are used as intended and under the conditions foreseen by the lift installer or escalator and/or moving walk manufacturer. This International Standard also comprises a list of documentation requirements for the installation and use of the apparatus.
This International Standard does not address all life cycle phases of the apparatus/assembly of apparatus such as manufacturing phase, construction phase, etc. The manufacturer should utilize other standards, e.g. ISO 14798 , to assess risks during these phases and address them with respect to EMI phenomena.
This International Standard only covers performance criteria and test levels for apparatus/assembly of apparatus used in general function circuits in environmental conditions defined by the manufacturer (temperature, humidity, etc.).
