SECTION 1-1.4: PROOF TEST AND PROOF LOAD
1-1.4.1 Proof Test Requirements
(a) Each newly designed mechanical jack shall be proof tested by the manufacturer.
(b) All newly manufactured mechanical jacks shall be proof tested by the manufacturer with the jack extended to a point of at least 25% of travel.
(c) The manufacturer or a qualified person shall determine if a proof test is required for any altered, modified, or repaired mechanical jack.
(d) After proof testing, the mechanical jack shall be thoroughly inspected for the conditions stated in para. 1-1.8.4.
1-1.4.2 Proof Load Requirements
(a) When proof testing a newly designed mechanical jack
(1) the jack’s load point shall be loaded to 110% of its lifting rated load and operated to its full length of travel through ten cycles (dynamic test).
(2) the jack’s load point shall be loaded three times to 150% of its rated load. The rack bar or screw shall be at least 90% of full travel. After this test, the jack shall be functional for full extension under 100% of rated load (static test).
(3) each auxiliary load point shall be proof tested in accordance with the same cycles and percentages described in paras. I-1.4.2(a)(l) and (2).
(Ii) The proof load for each newly manufactured mechanical rack shall be a minimum of 100% of the rated load.
(c) The proof load for each altered, modified, or repaired mechanical tack shall be a minimum of 100% of the rated load unless otherwise determined by the manufacturer or a qualified person.
SECTION 1-1.5: IDENTIFICATION
