EN 948-1999 pdf download.Hinged or pivoted doons-Determination of the resistance to static torsion.
Tins EN 948 applies to all vertically hinged or pIvotc(l (kX)I’S.
The stan(bnl specifies the method to be used to (lelerntme the permanent deformation caused when static stre4 in torNion is applied to an open door leaf fixed in its own door frame as part of a doorset.

The method may also be LLsed in respect of a (loor leaf subnutted for test in a frame which the manufacturer eonstdeni ap)mpnnte to and t,pical for the inteitcied UtilIZation.
2 Apparatus
2.1 Test surround
11w surround in which the test specimen is tested, which shall Lw sufficiently ngid to withstand the test load without (lefieetmg to an extent likely to influence the tesi result
2.2 Loading equipment
A suitable derice, with weights or a controlled and
calibrated rant, accurate to 2 9t
2.3 Measuring equipment
A dud or thqital go uqe, accurate to O01 nun.
3 Thst specimens
lèit specimens shall be stored and tested in a non-destructive environment within the ranges of 15 C to :30 °C and 2596 to 75% relative huniidit
L)oors which are designed to be glazed, shall be supplied for testing with all glazing carried out in accordance with the door manufacturer’s specification.
4 Procedure
Without any vertical restraint, position the door leaf at an angle of (90 ± 5)° to the plane of the frame, and fix the top hwkside corner at a point (50 ± 5) mni from each edge of the door leaf.
To take up any slack in the hinges, carefully apply a iweload of (200 ± 4) N, horizontally and nonnal to the plane of the leaf at the lower lockside corner, at a point (50±5) mm from each edge of the door leaf. Maintain this load for (60 ± ) s. Remove the load and after (60±5) s measure, to the nearest 0,1 nun, nw location of the lower corner of the door leaf at the loading position (see Figure I).
To the same loading point apply a static load F and maintain for (:1(X) ± 5) s Measure the maxiniuni deforniation under load to the nearest 0, 1 mm. Renuwe the load and after (180±5) S repeat the measurement at the lower corner of the door leaf.
All loads shall be carefully applied and removed in maximum 100 N, accurate to 2 96 increments and over a minimum of 1 s for each increment, or the equivalent rafr if conhinhious, in order to avoid dynamic effects.
5 Expression of results
Record:
— the (lefonnation wider load F awl the residual defonuation of the door leaf as expressed by the difference in the nieasurenwnts at the lower corner of the door leaf before the application of load F and (180 ± 5) s after the removal of this load.
6 Test report
The test report shall contain the following infonitation:
a) reference to this Ew’opean Standard;
b) all necessary (letalLs to kfrt1ufy (1w doonet or door leaf;
c) all relevant details concerning the type. specified dimensions, materials, fonu and construction of the doorset or door leaL including the position of hardware:
d) full (letalls of the frame and hanlware supplied ii’ the assembly is not a doorset;
e) laboratory storage and testing conditions.EN 948-1999 pdf download.
