23、nd longer.It is applicable to these types of industrial trucks that are equipped with forks, a spreader, (top lift and side lift), or other load handling means applicable for container handling.This International Standard does not apply to trucks when handling a container which has a mobile centre o
24、f gravity (see ISO 3874).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

30、vated container permits an operator in a low position on the truck to see underneath the container.5 Test condition5.1 GeneralSee ISO 22915-1.The tests take into account the normal degree of eccentric loading of containers defined in ISO 3874.When handling empty containers with integral refrigeratio
31、n unit (reefer), as specified in ISO 1496-2, account needs to be taken of the offset loading according to ISO 22915-20.5.2 Prevailing windThe tests shall not be carried out in a prevailing wind that would significantly affect the test results.5.3 Wind force5.3.1 Longitudinal testsFor the longitudina
32、l tests, the wind force acting on the freight container is calculated by Formula (1):FhLv Cwf= 221(1)whereF wind force (N); air density 1,225 kg/m3(at 15 C);h freight container height 2,90 m (9 ft 6 in);L freight container length (m) (longest container length the truck is designed for);vwrated wind

For the lateral tests, the wind force acting on the
35、 container shall be calculated by Formula (2) (see also Figure 1):FvChLawawf= +222(sin cos) (2)whereF wind force N; air density 1,225 kg/m3(at 15 C);vwrated wind speed 12,2 m/s;Cf2shape coefficient 0,8;h freight container height 2,90 m (9 ft 6 in);L freight container length (m) (longest container le

38、9:2014ISO 22915-9:2014(E)5.4 Position of the truck on the tilt tableThe truck shall be positioned on the tilt table according to Table 1. The indication of load and steer axle is the centreline of the load and steer axle. The allocation of the indication is defined in Figure 2.BAACBCKeyA-A longitudi
39、nal centre plane of the truckB-B steer axleC-C load axleFigure 2 Longitudinal centre plane and axlesFor tests 1 and 2 (see Table 1), the truck shall be positioned on the tilt table, so that the load axle C-C is parallel to the tilt axis X-Y of the tilt table.For tests 3, 4, and 5 (see Table 1), the
40、truck shall be positioned on the tilt table in a turning position with line M-N parallel to the tilt axis X-Y of the tilt table. The steer wheel nearest to the tilt axis of the tilt table shall be parallel to the tilt axis.Point M is defined as the intersection of the longitudinal centre plane, A-A,
41、 of the truck with the projection of the pivot point of the articulated steer axle onto the tilt table.Point N indicates the centre point of the area of contact between the tilt table surface and the load wheel nearest the tilting axis.5.5 Test load5.5.1 GeneralThe test load shall consist of a load
42、corresponding to the weight of the container and a load or force simulating the effect of the wind on the container.5.5.2 Basic loadThe test load shall be equivalent to a container 2,90 m (9 ft 6 in) high (see ISO 668), in either the laden or unladen condition, with a mass equivalent to the rated lo
43、ad as specified by the manufacturer, acting through its centre of gravity.When using fork arms to handle containers, the test load shall act through the centre of gravity positioned 1 220 mm horizontally from the front face of the fork arm shank and at a height that corresponds to the midpoint of th
44、e height of a 2,90 m (9 ft 6 in) container.When using top lift, side lift, or other load handling means, the position of the centre of gravity shall be determined by the connection points to the test load, e.g. twist locks into the corner fittings.4 ISO 2014 All rights reservedBS ISO 22915-9:2014ISO
45、 22915-9:2014(E)Where the load handling means can be adjusted laterally to the truck longitudinal centre line, ISO 22915-10 can apply.Where the load handling means has positional adjustment capability in the direction of the truck longitudinal centre line, other than mast tilt, the tests shall be ca
46、rried out at both extremes of adjustment.5.5.3 Wind forceThe effect of this force can be simulated in the tests by one or the other of the following methods:a) applying this force normal to the lateral tipping axis of the truck horizontally through the load centre of gravity;b) applying a vertical l
47、oad, in addition to the test load, giving an equivalent moment to the wind force acting when the slope is at the required tilt angle as specified in the table of tests.5.6 Lift height5.6.1 Lift height for tests simulating stackingTest 1 (see Table 1) shall be conducted with the horizontal position o
48、f the load datum point (e.g. point E) unchanged when elevated from its lowered position see Figure 3 a), b) and c).With the prescribed test load, set the mast vertical and perpendicular to the tilt table and then elevate to approximately 300 mm. Using the shank of the front face of the fork arm or l
49、oad-engaging means, establish a point E see Figure 3 a), on the fork arms or load-engaging means having a fixed relationship to the centre of gravity of the test load. This point E shall be used to provide a reference datum F on the tilt table. When the mast is elevated, a new point F1 on the tilt table may occur see Figure 3 b). By the following adjustments, this new point F1 can be returned to the original location of F see Figure 3 c).Changes in the location of F1 shall
