3.15
working circuit hydraulic pressure
normal operating pressure applied to the specific circuit by the pump(s)
3.16
rnaximuni relief circuit hydraulic pressure
maximum static pressure in a speafic circuit limited by a relief valve at a flow no greater than 10 % 01 the rated cWcuit flow
hydraulic limit
condition when the tool forces are limited by maximum relief circuit pressure
3.18
tipping limit
condition when the tool forces are limited by the onset of tipping of the machine
3.19
supping limit
condition when the tool forces are limited by the machine slipping on the test swface
4 Measurement methods
4.1 Test site and general
The test site shall consist of a level, hard surface, with anchor points and space for using the meas1ng devices specified in 4.2,1 to 4.2.3. For measurements made below the ground plane, a space below that plane is required for acceptance of the machine tool and the measurement devices, the anchorage and any auxiliary equipment
All measurements shal be accurate to Withifl ± 2 % or shall accord With an International Standard relative to test equipment accuracy.
In the preferred method, the force to be measured Is applied directly to the force measunng device (4.2.1). If the force is applied via a pulley, its friction should be taken into account The wire rope (4.2.4) should be as short as possible to minimize the affect on accuracy.
4.2 Test apparatus
4,2.1 Force measuring device, of accuracy according to ISO 9248.
4.2.2 Hydraulic oil pressure measuring device, of accuracy according to ISO 9248.
4.2.3 Instrument(s) for measuring linear dimensions, of accuracy according to ISO 9248.
4.2.4 Wire ropes and shacklespulleysatety chains and adjustable supporting frames.
