A3. Landing doors

A3.1. General

A3.1.1. The openings in the well giving access to the lift car

should be fitted with imperforate doors. When closed those doors

should completely cover the openings, subject to the necessary

clearance, which should be as small as possible and in any case

less than ¼in. (6mm).1

A3.2. Strength of landing doors and their frames

A3.2.1. (1) Doors and their frames should be so constructed

that the doors will not become deformed in the course of time.

It is recommended that metal doors should be used in all cases.

(2) The use of glass, even wired glass, or of plastic material should

be allowed only for the vision panels referred to in A3.6.2(a).

A3.2.2. Landing doors should comply with the fire prevention

and protection rules in the country where the lift is installed. In

addition, without necessarily being as fire-resistant as the walls

of the well onto which they open, landing doors should afford

a degree of protection against fire corresponding to that required

for those walls.

A3.2.3. Doors and their locks should have adequate strength

and rigidity.2

For the requirements respecting the car side of landing doors see Al .7.1.

2 In this respect the following criteria could be adopted:

(a) locked landing doors should withstand without permanent deformation

a horizontal force of 661bf (3Okgf or 3OdaN) applied at any point on

either side of a door panel, this force to be evenly distributed over an area

of 4sq.in. (25cm2) in a round or square section. After this the doors

should function normally;
