5、tor Mounting Adaptor as per attached Drawing #3 is used to connect the pulley with the cell in the Instron. Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 OC and 50 +/- 5 % relative humidity for not less than

6、 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure 1. Condition the weatherstrip samples for 24 h at 65 +/- 2 % relative humidity and at a temperature of 70 +/- 2 OF. Specimens for the wet test must be soaked for 1 h in tap water at a temperature of 70

7、+/- 2 OF. 2. Set up “C“ cell in Instron with pulley adaptor. At the universal joint shims are to be used to lock the assembly in place. (See attached Drawing #2.) 3. Balance and zero the Instron and integrator. 4. Calibrate the instrument and integrator following the directions in the instruction ma

8、nual, then proceed as follows: (a) Clear the counters on the integrator and turn the integrator counter switches to the “On“ position. Turn manual-automatic switch to “Automatic“ position. (b) Set crosshead speed to 20 inches/minute by using proper gear combination as shown in gear selection chart f

9、or various crosshead speeds (see manual). (c) Set chart speed to 5 inches/minute by using proper gear combinations (see manual) (d) Set full scale load to 50 Ib range. (e) Set buck assembly in center of Instron. 5. Determine the weight and integrator input value of the glass as follows: (a) Without

10、any weatherstrip in the channels, connect up the glass in the buck so that it is suspended freely between the channels. (b) Push the “Down“ button to start the crosshead in motion to raise the glass once (c) Record the integrator input reading for the weight (W) of the glass. Page 2 of 7 Copynght020

Install the flocked rubber weatherstrip samples in each channel run. Insert the glass in the weatherstrips and slide the gla

12、ss to the bottom of the channel runs. Hand cycle the glass up and down in the channel for four complete cycles (up and down = 1 cycle). Reconnect cable and hook to glass. Clear counters on the integrator. Start the test by pushing the “Down“ button and raise the glass once through a distance of 20 i

13、nches. Read the counter on the integrator and record the input units (X) for the friction of the glass and weatherstrip. Calculate and report the frictional effort as follows: F =IS - W) x L x S 5000 Where: F = Frictional effort in inch Ibs X = Input units (Step 12) L = Full scale load in pounds (50

14、 Ibs) S = Rate of crosshead travel (20 inches/minute) W = Integrator Input Units (Step 5C) Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities. Page 3 of 7 Copyng
