What is ISO 8102-2 about?
ISO 8102-2 discusses electrical requirements for lifts, escalators, and moving walks. ISO 8102-2 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 regarding their electromagnetic environment. These levels represent essential EMC (electromagnetic compatibility) requirements. ISO 8102-2 refers to EM conditions as existing in residential, office, and industrial buildings.
ISO 8102-2 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. It is assumed that no ports connected to the 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).
However, performance criteria and test levels for apparatus/assembly of apparatus used in general function circuits do not cover situations with an extremely low probability of occurrence.
Note 1:ISO 8102-2 does not apply to other apparatus already proven to be in conformity to the EMC national regulation, and not related to the safety of the lift, escalator or moving walk, such as lighting apparatus, communication apparatus, etc.
Note 2: ISO 8102-2 does not apply to electromagnetic environments such as:
- radio transmitter stations
- railways and metros
- heavy industrial plant
- electricity power stations, which need additional investigations
Note 3:ISO 8102-2 is not applicable to apparatus which were manufactured before the date of its publication.
Who is ISO 8102-2 for?
ISO 8102-2 on electrical requirements for lifts, escalators and moving walks is useful for:
- Lift Manufacturer
- Escalators Manufacturer
- Lift/Escalators Maintenance department
Why should you use ISO 8102-2?
Electromagnetic compatibility or EMC means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment and it does not emit levels of EM energy that cause electromagnetic interference (EMI) in other devices in the vicinity.
ISO 8102-2 will help you to ensure a level of electromagnetic immunity which will allow minimal disturbance. Two levels of immunity are given which have been selected such that the immunity levels for safety circuit apparatus are higher than the immunity levels for general function apparatus. The higher levels cover the possibility for example of disturbances emanating from hand-held transmitters near safety circuit apparatus. Test levels and immunity performance criteria are defined for apparatus which are safety components or are used in conjunction with safety components, (safety circuits) and apparatus used in general function circuits.
