Component Description
View A: Loading unit Applies load to the specimen during the test. Consists of: a tension crosshead
1
,
two notched columns
1
, a compression table, and the hydraulic cylinder.
View B: Fixed unit Remains fixed during the test. Consists of: an adjustable crosshead, two screw
columns, and the base.
1. Grip assemblies
1
Secure a specimen for tensile testing. Grip assemblies are operated either
manually (G1-style crossheads) or hydraulically (G7-style crossheads). Refer to
“Operate grip assemblies - G1-style and G7-style crossheads” on page 42
for more information.
2. Test space
a. Tension
1
b. Compression
Area where tests are performed. The DX is a dual test space frame. The tension
test space is between the tension crosshead and adjustable crosshead. The
compression test space is between the adjustable crosshead and compression
table.
The vertical opening of each test space can be adjusted. Refer to “Change
height of tension test opening” on page 38 and “Change height of
compression test opening” on page 41 for more information.
3. Tension crosshead
1
a. G7-style
b. G1-style
Provides upper grip for tension specimen. Also provides mounting surface for
external tension fixtures, refer to “Mount fixtures” on page 34 for more
information.
The position of the tension crosshead can be adjusted to change the vertical
opening of the tension test space. Refer to “Adjust the position of the tension
crosshead” on page 38 for more information.
4. Adjustable crosshead
a. G7-style
b. G1-style
c. G8-style (not shown)
For tension testing, provides lower grip for tension specimen. Also provides
mounting surface for external tension fixtures. Refer to “Mount fixtures” on
page 34 for more information.
For compression testing, the bottom of the crosshead provides mounting surface
for upper compression fixtures - do not test directly against the bottom of the
adjustable crosshead. Refer to “Mount fixtures” on page 34 for more
information.
The position of the adjustable crosshead can be adjusted to change the vertical
opening of either test space. Refer to “Operation of controls” on page 29 for
more information.
5. Compression table Provides mounting surface for lower compression fixtures - do not test directly
against the compression table. Refer to “Mount fixtures” on page 34 for more
information.
6. Load cell Measures the force applied to the specimen.
7. Notched columns
1
Connect the tension crosshead to the compression table. Notches allow position
of tension crosshead to be adjusted. Refer to “Adjust the position of the
tension crosshead” on page 38 for more information.
8. Screw columns Connect the adjustable crosshead to the base. Threaded portion of columns
allows position of adjustable crosshead to be adjusted. Refer to “Operation of
controls” on page 29 for more information.
9. Base Provides mounting for hydraulic cylinder. Houses the hydraulic power supply
(HPS).
1. These items provided on frames with G1-style or G7-style crossheads only.
