5 Safety requirements and/or protective measures 5.1 General 5.1.1 Passenger and goods passenger lifts shall comply with the safety requirements and/or protective measures of the following clauses. In addition, passenger and goods passenger lifts shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant which are not dealt with by this document (e.g. sharp edges). The requirements of EN 81 -20 and EN 81-28 apply with additional requirements elaborated below. 5.1.2 Where luminance contrast between adjacent surfaces is required the difference in light reflectance value (LRV) shall comply with Table 2. Light reflectance values under viewing angles according to Table 2 taking into account lighting conditions and reflections of ceilings, walls and floors may be determined by a black and white photo of a sample with an adjacent LRV scale and comparing surfaces of the sample with the LRV scale. Alternatively, by placing a LRV scale against the surface of interest, a reasonable match can be identified. NOTE On shiny and direct reflective surfaces, unfavourable reflections can reduce luminance contrast determined by LRV-method. Light colour tones for ceiling and wall surfaces, diffuse reflective materials and a wide light distribution prevent disturbing reflections on the controls. For further guidance on contrast see ISO 21542:2011, B.7.2.
5.1.3 When an audible signal or voice announcement is required, the sound level shall be adjustable between 35 dB(A) and at least 65 dB(A) and to suit the site conditions. In noisy environments (e.g. on landings in train stations) the maximum sound level shall be adjustable up to 80 dB(A) (see 0.4). The means of adjustment shall be accessible only to authorized persons.
5.2 Entrances – Door openings
5.2.1 The landing and car doors shall be automatic power operated horizontally sliding doors.
The clear opening width shall be at least 800 mm for type 1 cars, 900 mm for type 2, type 3 and type 4 cars and 1 100 mm for type 5 cars. In existing buildings, the clear opening width shall be at least 800 mm fortype2cars.
5.2.2 The door dwell time shall be adjustable at least between 2 s and 20 s to suit the conditions where the lift is installed (see 0.4). The means of adjustment shall be accessible only to authorized persons.
NOTE A door dwell time of at least 6 s is needed for persons with reduced mobility (see also 5.4.2.2.3).
A door close button may be provided to reduce the door dwell time.
5.3 Car dimensions and equipment in the car
5.3.1 Car dimensions
The inside dimensions of cars with a single entrance or with two opposite or two adjacent entrances shall be chosen in accordance with Table 3 (see 0.4).
Car dimensions shall be measured between the structural car walls. Decorative finishes on each wall that reduce the minimum car dimensions given by Table 3 shall not exceed 15 mm in thickness.AS 1735.12 pdf download.
