<br />, <br /> <br />The ladder is placed in a flat horizontal position, extended a minimum of one rung beyond the <br />bedded position. A test load is placed on the ladder in such a manner as to subject the lock <br />hardware to a 1 ,OOO-pound load. The test load is applied for a minimum of 1 minute. <br /> <br />Results: <br /> <br />The ladder shall sustain this test load with no permanent deformation or other visible weakening <br />of the structure. <br /> <br />HOOK TEST (Roof Ladders Only: <br /> <br />The ladder hook angle relative to the ladder side rail is recorded. A load of 1,000 pounds is then <br />applied to the hook tip, parallel to the ladder side rails. The test load is maintained for a <br />minimum of 1 minute. The test load is removed and the roof hook angle relative to the ladder <br />side rail is again measured. <br /> <br />Result: <br /> <br />There shall be no permanent deformation. <br /> <br />HARDNESS TEST (Metal Ladders Only) <br /> <br />METHOD: <br /> <br />A hardness test shall be performed at a test point located between every rung on both side rails. <br />For beams of truss construction, the test points are located on both the top chord, and the bottom <br />chord of the truss, between every rung on both side rails. <br /> <br />Results: <br /> <br />All hardness readings recorded must be at or above the minimum reading as specified by Table <br />5-4.4 ofNFPA 1932. <br /> <br />HEAT SENSOR LABELS: <br /> <br />The testing company shall check all heat sensor labels for current date and proper location. If <br />heat sensors are needed, they shall be provided by Santa Ana Fire Department. <br /> <br />12 <br />
