6.1.6 Load test of ropes，belts，chains and attachment components.
Pull out the rope，belt or chain (80 +/_ 10) % of the range of motion and clamp it. Apply the test load to the handles to load the ropes，belts，chains and attachment components between clamp and handles.
6.2 Testing of seat
Apply the load in accordance with 5.2.4 for more than 1 minute, Check whether the seat always remains attached to the rail.
6.3 Testing of temperature rise
Measure the temperature with an accuracy of +/- 1 degree.
Operate the rowing equipment for (20 士 1) minutes with the following values:
- frequency of 30 /min
- ( 60~65) % of the maximum range of motion of the hand grip; at maximum resistance for the rowing equipment.
Within 10 seconds after the test，measure the temperature of all exposed surfaces.
6.4 Testing of intrinsic loading
Place the rowing equipment freely on a flat floor and clamp the seat in the most onerous position along the rail.
Apply the test force specified in 5.3 to the centre of the seat using a (300+/-5) mm x (300+/- 5) mm plate for at least 2 minutes. The equipment shall not be fixed to the floor during the test.
6.5 Testing of foot strap
Apply the test force specified in 5.6 at the centre of the foot-strap using (80 士 5) mm wide belt for a period of (2 士 1) min
6.6 Testing of foot support
