TNJ-101 Seat Durability Tester--Durability test on seating with a multi-position back rest

This test is only applicable to seating with three or more manually adjustable reclined positions of the back rest.
Place the seating in normal use position, with the back rest in the most adverse position. If the most adverse position cannot be determined, carry out the test with the back rest in the mid position. Prevent the item of seating from moving rearwards by placing stops behind the rear feet, legs or castors.

Apply the specified load to the seat loading point.

The height of the back rest loading points shall be 100 mm above the back loading point (6.2). They shall be 50 mm from the right and left outer edges of the back rest.

Apply rearwards alternating forces perpendicularly to the back rest, as specified.

Carry out the test for the number of cycles specified.

1 cycle = 1 application of force on the right side and 1 application of force on the left side.

NOTE This test is often used for testing outdoor reclining seating.
