1. G1 = Dual test space with open-front crossheads and manual crank and pinion grip actuation
G7 = Dual test space with open-front crossheads and hydraulic grip actuation
G8 = Compression only test space with open-front adjustable crosshead
E1 = Standard tension opening
E2 = Extended tension opening by:
- 610 mm (24 in) for 300DX frames
- 406.4 mm (16 in) for 600DX frames
2. Long term static tests should be limited to 30 minutes or less when the test is performed at or near maximum capacity. Time
varies inversely with test load. 50% maximum capacity tests should be limited to 60 minutes or less. An oil temperature
switch limits test duration based on safe reservoir temperature. Assumes ambient temperature of 25 deg C (77 deg F).
3. The design capacity is the peak load at which the frame should be used for no more than 80% of the time. In other words, at
least 80% of specimen testing should be conducted at peak loads that are at or below the design capacity. The frame should
only be used at loads between the design capacity and the maximum capacity less than 20% of the time.
4. Minimum and maximum tension test opening is provided for each crosshead style and each notch position of the tension
crosshead. First notch position is with the tension crosshead in the lowest notch on the columns. Number of notch positions
provided depends on frame height option purchased; not all frames have all notch positions listed. Minimum opening is with
the hydraulic cylinder fully retracted and the adjustable crosshead in highest position. Maximum opening is with the hydraulic
cylinder fully extended and the adjustable crosshead in lowest position. Values do not include crosshead thickness or any
specimen fixtures.
5. First notch should not be used; crosshead interference can occur.
6. Minimum compression test opening measured with the hydraulic cylinder fully extended and adjustable crosshead in lowest
position. Maximum compression test opening measured with the hydraulic cylinder fully retracted and adjustable crosshead
in highest position. Values do not include specimen fixtures.
7. The General Assembly drawing is located in the separately supplied “Reference Manual-Equipment”. General Assembly
drawings are model specific; please be sure to refer to the appropriate drawing for your model and its configuration.
8. Several sets of grip jaws may be required to cover the range.
9. Adjustable crosshead speed is approximate and provided for reference only. Adjustment speed may vary depending on
crosshead type and fixtures attached to adjustable crosshead.
10.Under no load conditions. Accuracy is affected under load. The encoder cannot compensate for frame deflection (axial
stiffness) or the load cell and load string deflections. Over short travels and higher loads, the error could be over 100%.
Conversely, over longer travels and lower loads, the error may be insignificant. The axial frame stiffness and load cell stiffness
values published may be used to assess this affect. The load string also needs to be considered. In general, the extension
(position) readout should not be used as the primary strain measuring device where an extensometer on the specimen is
clearly warranted. Frame compliance can be accounted for to some extent by Instron software.
11.At speeds below approximately 0.1 mm/min (0.004 in/min) the hydraulic cylinder moves in increments approximately equal to
these values and can be seen as load steps depending on the specimen stiffness and load range.
12.Alignment of the grip wedge pockets is measured with approximately 200 mm (8 in) between crossheads in the tension test
space.
13.Parallelism is measured under no load conditions between the table and underside of the adjustable crosshead.
