36、 Tests 1The truck shall be positioned on the tilt table according to the following: in Test T1A, each of the two tipping lines, BB and CC, shall be parallel to the tilt axis, XY, of the tilt table and one at a time the nearest to the tilt axis, XY, of the tilt table (see Table 1); in Test T1B, each
37、of the two lateral tipping lines, BC, shall be one at a time parallel and the nearest to the tilt axis, XY, of the tilt table (see Table 1).4.2.2 Test 2The truck in forward aligned position (see ISO 10896-2) shall be positioned on the tilt table so that its forward tipping line, BB, is parallel and
38、the nearest to the tilt axis, XY, of the tilt table. See Table 1.4.2.3 Test 3The truck shall be positioned on the tilt table according to the following: in Test T3A, each of the two lateral tipping lines, BC, shall be one at a time parallel and the nearest to the tilt axis, XY, of the tilt table; in
39、 Test T3B, each of the two tipping lines, BB and CC, shall be parallel to the tilt axis, XY, of the tilt table and one at a time the nearest to the tilt axis, XY, of the tilt table.For Tests T3A and T3B, the upper structure shall be in the least favourable position in accordance with Table 1.For the
40、se tests, if necessary, it is advisable to secure the slewing upper structure to the lower chassis to avoid the risk of uncontrolled movement.4.2.4 Test 4The truck in forward aligned position (see ISO 10896-2) shall be positioned on the tilt table so that each of the two lateral tipping lines, BM, i
41、s one at a time parallel and the nearest to the tilt axis of the tilt table. Lateral test shall be carried out in the least favourable condition to the side, which the truck is less stable.4.2.5 Test 5The truck shall be positioned on the tilt table so that each of the two lateral tipping lines, BC,
42、is one at a time parallel and the nearest to the tilt axis, XY, of the tilt table.The longitudinal centre plane of the upper structure shall be perpendicular to the XY plane with the boom facing up the slope. See Table 1.4.2.6 Test loadTest 1 and test 3 shall be conducted with the test load in the l
43、east stable combination of lift and reach, with the fork arms parallel to the tilt table, and this shall remain unchanged during the tests.The centre of gravity, according to ISO 10896-2, shall be positioned on the longitudinal centre plane of the upper structure, except where a lateral slope correc
44、tion device is used, which is the case for Tests 3. See Table 1.

45、d, shall be positioned 500 mm from the ground.Test 5 shall be conducted with the boom fully retracted, at the maximum boom angle and with the fork arms in the horizontal position. See Table 1.4.2.8 Lateral test procedureFor trucks fitted with chassis levelling, Test 3 shall be performed with the max
46、imum lateral slope correction provided by the truck without exceeding 7 %. Lateral slope correction shall only be achieved by chassis levelling.For trucks not fitted with automatic non-freely oscillating axle, Test 3 shall be conducted both in the oscillating and the non-oscillating axle modes. When
47、 the axle is in the oscillating mode, lateral tipping lines for the axle in the non-oscillating mode, B-C, shall be replaced by lateral tipping lines for the axle in oscillating mode, B-M, in accordance with 4.1.1.2.For the other tests, the lateral slope correction shall not be used.5 Verification o

49、the vertical plane passing through one tipping line at a time. The chassis shall be levelled.Where the truck is rated for lifting operations on stabilizing devices on a gradient exceeding 1 %, then tests shall be carried out with truck positioned at the slope designated by the manufacturer.The stability of the truck on stabilizing devices under static conditions shall be such that the actual capacity at the least stable boom angle and length combinatio
