Electromechanical Tensile Testing Machine 100kN floor standing type
for composites wood metal tensile test ETM105D
Two steel columns provide highly accurate guidance for WANCE's
moving crosshead. The stiff load-frame profile and generous
connecting surfaces reduce the inclination angle of the crosshead
under load, enabling very precise alignment and application of
force to the specimen. This is advantageous for flexure tests,
compression tests, precision tests on components etc.
The two-channel safety circuit, including Emergency STOP, crosshead
limit stop switch and interlinked accessories, Drive OFF switch and
motor brake function, together with the operation mode switch,
ensure enhanced safety during setup. The CE-compliant electrically
interlocked safety device prevents interference with the machine
during the test.

1. The accuracy of the testing machine shall be within the
permissible variation specified in Practices E 4.
2 Precaution should be taken to assure that the force on the
specimens is applied as axially as possible. Perfect axial
alignment is difficult to obtain especially when the pull rods and
extensometer rods pass through packing at the ends of the furnace.
However, the machine and grips should be capable of loading a
precisely made specimen so that the maximum bending strain does not
exceed 10 % of the axial strain, when
the calculations are based on strain readings taken at zero force
and at the lowest force for which the machine is being qualified.
NOTE 1—This requirement is intended to limit the maximum
contribution of the testing apparatus to the bending which occurs
during a test. It is recognized that even with qualified apparatus
different tests may have
quite different percent bending strain due to chance orientation of
a loosely fitted specimen, lack of symmetry of that particular
specimen,lateral force from furnace packing, and thermocouple wire,
etc. The scant
evidence available at this time3 indicates that the effect of
bending strain on test results is not sufficient, except in special
cases, to require the measurement of this quantity on each specimen
In testing of brittle material even a bending strain of 10 % may
result in lower strength than would be obtained with improved
axiality. In these cases, measurements of bending strain on the
specimen to be tested may be specifically requested and the
permissible magnitude limited to a smaller value.
In general, equipment is not available for determining maximum
bending strain at elevated temperatures. The testing apparatus may
be qualified by measurements of axiality made at room temperature
using the assembled machine, pull rods, and grips used in high
temperature testing. The specimen form should be the same as that
used during the elevatedtemperature tests and designed so that only
elastic strains occur
throughout the reduced section. This requirement may necessitate
use of a material different from that used during the
elevated-temperature test. See Practice E 1012 for recommended
methods for determining specimen alignment.
3. Gripping devices and pull rods may oxidize, warp, and creep with
repeated use at elevated temperatures. Increased bending stresses
may result. Therefore, grips and pull rods should be periodically
retested for axiality and reworked when necessary.
4. The testing machine shall be equipped with a means of measuring
and controlling either the strain rate or the rate of crosshead
motion or both to meet the requirements in 9.6.
5. For high-temperature testing of materials that are readily
attacked by their environment (such as oxidation of metal in air),
the specimen may be enclosed in a capsule so that it can be tested
in a vacuum or inert gas atmosphere. When such equipment is used,
the necessary corrections must be made to determine the actual
forces seen by the specimen. For instance, compensation must be
made for differences in pressures inside and outside of the capsule
and for any variation in the forces applied to the specimen due to
sealing ring friction, bellows or other features.
The apparatus for and method of heating the specimens should
provide the temperature control necessary to satisfy the
requirements specified in 9.4.
Heating shall be by an electric resistance or radiation furnace
with the specimen in air at atmospheric pressure unless other media
are specifically agreed upon in advance.
The method of temperature measurement must be sufficiently
sensitive and reliable to ensure that the temperature of the
specimen is within the limits specified in 9.4.4.
Temperature should be measured with thermocouples in conjunction
with the appropriate temperature indicating instrumentation.
NOTE 3—Such measurements are subject to two types of error.
Thermocouple calibration and instrument measuring errors initially
introduce uncertainty as to the exact temperature. Secondly both
thermocouples and measuring instruments may be subject to variation
with time. Common errors encountered in the use of thermocouples to
measure temperatures include: calibration error, drift in
calibration due to contamination or deterioration with use,
lead-wire error, error arising from method of attachment to the
specimen, direct radiation of heat to the bead, heatconduction
along thermocouple wires, etc.
Temperature measurements should be made with thermocouples of known
calibration. Representative thermocouples should be calibrated from
each lot of wires used for making base-metal thermocouples. Except
for relatively low temperatures of exposure, base-metal
thermocouples are subject to error upon reuse, unless the depth of
immersion and temperature gradients of the initial exposure are
Consequently base-metal thermocouples should be verified by the use
of representative thermocouples and actual thermocouples used to
measure specimen temperatures should not be verified at elevated
temperatures. Base-metal thermocouples also should not be reused
without clipping back to remove wire exposed to the hot zone and
rewelding. Any reuse of basemetal thermocouples after relatively
low-temperature use without this precaution should be accompanied
by recalibration data demonstrating that calibration was not unduly
affected by the conditions of exposure.
Noble metal thermocouples are also subject to errors due to
contamination, etc., and should be periodically annealed and
verified. Thermocouples should be kept clean prior to exposure and
during use at elevated temperatures.
Measurement of the emf drift in thermocouples during use is
difficult. When drift is a problem during tests, a method should be
devised to check the readings of the thermocouples on the specimen
during the test. For reliable calibration of thermocouples after
use the temperature gradient of the testing furnace must be
reproduced during the recalibration.
Temperature-measuring, controlling, and recording instruments
should be verified periodically against a secondary standard, such
as a precision potentiometer and if necessary re-calibrated.
Lead-wire error should be checked with the lead wires in place as
they normally are used.
