With the panels in the normal position, a concentrated load of 300 pounds shall be applied separately to each vertical pull stile incorporating a locking device at a point on the stile within six inches of the locking device in the direction parallel to the plane of glass that would tend to open the door.
2. Test B. Repeat Test A while simultaneously adding a concentrated load of 150 pounds to the same area of the same stile in a direction perpendicular to the plane of glass toward the interior side of the door.
3. Test C. Repeat Test B with 150–pound force in the reverse direction toward the exterior side of the door.
4. Tests D, E and F. Repeat Tests A, B and C with the movable panel lifted upwards to its full limit within the confines of the door frame.
5. Moveable panels shall not be rendered easily openable or removable from the frame during or after the tests or the panel shall have failed the test.
