13.2 Deflection — Compulsory pole
When tested in accordance with Annex B, compulsory pole ladders shall meet the following requirements.
The deflection due to the load applied in 8.4 shall not exceed 2,5 % of the span between the top two trestles (see Figure B.3).
The deflection due to the load applied in 8.5 shall not exceed 1.5 tries the deflection resulting from BA (see Figure B,3).
Within 60 s after removal of the load in 83 the distance D in Figure B.5 shall be the same as distance B ii Figure 8.3.
13.3 Other tests
Ladders shall be tested in accordance with the following annexes
Annex C. on completion or the test there shall be no discemible movement when turning the rung by hand;
Annex D. for compulsory pole ladders there shall be no visible damage after completion of the test;
— Annex B, ladders except 3-person compulsory pole ladders and hook ladders shall support the load for the time specified;
— Annex F. 3-person compulsory ladders shall support the load for the time specified; Annex G, extension ladders shall support the load for the time specified;
— Annex H. rescue tadders shall support the load for the time specified;
— Annex I, access ladders shall support the load for the time specified;
Annex J, ladders fitted with tip-loaded hooks shall support the load for the time specified; Annex K, ladders fitted with mkNoaded hooks shall support the load for the time specified;
— Annex 1, for ground standing ladders on completion of the test the permanent deformation obtained by subtracting measurement 1.6 from 1.3 and 1.9 from L6. shall not exceed 3 mm In each case.
14 General test parameters
When carrying out the tests set out in Annexes A to L the following conditions shall apply:
NOTE I The following tests are type tests and not penodical tests.
— loads shall be applied gradually with no dynamic or sudden loading.
— a measuring tolerance of ± 3 mm shal apply to all test measurements and results. Loads and forces shall be within ± 1% of stated figures;
— where fitted, extras shall be present at the time of testing;
— support of the test load shall be the only requirement in destructive tests;
NOTE 2 Permanent deformation resulting from destructive tests should not be taken as failure of the test.
M.1 Inspection and maintenance
M.1.1 The following test schedule is recommended for all types of ladders in use Facihties and ladder usage vary throughout Europe and therefore the actual test programme should be determined by the relevant authority In each country.
M.1 .2 Ladders should be inspected and maintained by competent personnel in accordance with the manufacture?s instructions. for example once every month, and after each usage.
M.1 .3 The following items should be included in the inspection where applicable:
all rungs for tightness;
— all bolts and rivets, to tightness (without crushing the structure):
— welds, for any cracks or apparent defects.
— stiles and rungs, for cracks, splintering, breaks, gouges or deformation:
feet, for excessive wear or other defects;
— an operational check of the pawl and locking assemblies for proper operation.
M.1 .4 Ensure that ladder markings are clearly legible and replace when necessary.
M.1 .5 If, in an emergency, ladders have been used other than as specified in this standard, they should be removed from service, inspected and tested prior to further use.
M.1.6 Damaged ladders, or ladders having defects, should be removed from service, repaired and tested pnor to further use,
M.2 Non-destructive test schedule
M,2,1 All ladders should be tested according to the following schedule:
annually:
— at any time a ladder is suspected of being unsafe;
after the ladder has been subiected to other than normal use:
— after the ladder has been subjected to Impact loading or unusual conditions of use:
— after heat exposure.
