TEST PRODUCE (ISO 7170):

7.1.4 Durability of pivoted doors

Attach two masses, each, one on each side of the door at the middle of the vertical centreline (see Figure 1 1 ).

Fully open the door to a maximum of and close it for the number of cycles (back and forth) specified, without forcing built-in stops in the open position.

If the door has a catch device at any position, operate this mechanism at each cycle.

The door shall be gently opened and closed at each cycle using approximately for opening and for closing the door.

The recommended rate is a maximum of 6 cycles per minute.

Carry out the inspection and assessment according to 4.8.

7.5.3 Durability of extension elements

Load the extension element as specified. When configured for pocket files, load it uniformly with paper (5.8) as shown in Figure 18.

Without impacting the stops, or providing vertical support, open and close the extension element gently for the number of cycles specified. Extension elements that do not have open stops shall be opened to a point at which

one-third of the inside length (depth) of the extension element, or at least , remains inside the unit (see Figure 19).

If the extension element has a catch device at any position, this shall be allowed to operate at each cycle.

The force shall be applied via the handle or, in case of two handles, in the middle between the handles. On

extension elements without a handle, apply the force at the same level as the runners.

The extension element shall be opened/closed gently at a rate of 6 to 15 cycles per minute.

The recommended average speed is (0.25 ± 0.1 ) m/s.

Carry out the inspection and assessment according to 4.8.

7.5.4 Slam shut/open test of extension elements

The slam-open part of the test is applicable only to extension elements fitted with stops in the open position.

Place the extension element on its runners and load it as specified with marbles (5.7), or, when configured for

pocket files, load it with paper (5.8) as shown in Figure 18.

Open the extension element , or fully open it if it can not be opened . Extension elements

without stops in the open position shall be opened until remains inside the unit.

Slam shut the extension element 1 0 times using the velocities specified.

NOTE Two suitable slam-test apparatus are shown in Annex B.

The slamming force shall act until before the extension element reaches its end travel.

Apply the force to the handle or, in case of two handles, in the middle between the handles. On extension

elements without a handle, apply the force at the same level as the runners.

Carry out slam open according to the same principle as above, if the extension element is fitted with stops in the

open position.

Carry out the inspection and assessment according to 4.8.
