ASTM D257 -
National Technical Systems
These test methods cover direct-current procedures for the measurement of dc insulation resistance,volume resistance, and surface resistance. From such measurements and the geometric dimensions of specimen and electrodes, both volume and surface resistivity of electrical insulating materials can be calculated, as well as the corresponding conductances and conductivities. These test methods are not suitable for use in measuring the electrical resistance/conductance of moderately conductive materials. Use Test Method D4496 to evaluate such materials. This standard describes several general alternative methodologies for measuring resistance (or conductance). Specific materials can be tested most appropriately by using standard ASTM test methods applicable to the specific material that define both voltage stress limits and finite electrification times as well as specimen configuration and electrode geometry. These individual specific test methodologies would be better able to define the precision and bias for the determination.

TF225 -
TESTEX Testing Equipment Systems Ltd.
Circular Locus Tester, to determine surface deterioration and quality of fabrics (wool, chemical fiber, mixed, kitted and woven fabrics). Using an active friction system, fabric is rubbed against a nylon brush and abrasive or an abrasive only under controlled conditions. Results of the test are achieved in minutes. The relative motion of the locus specimen grip and the abrasive platform is a circle with a relative speed of 60+/-1 r/min. The grip offers pressure to the specimen which is adjustable with a tolerance of +/-1%. For added control and safety, the machine is equipped with a self-stop switch.

Darwin Chambers Company
Standard walk-in incubators or coolers used in the rearing of drosophila and other biological organisms often end up being problematic for a number of reasons. The acids inherent in the rearing of many specimens or their food can quickly corrode a standard refrigeration evaporator. High humidity exacerbates the issue, as droplets of concentrated acid will collect on the cooling components.

attoCRYO -
attocube systems AG
Fundamental research in physics, as well as specimen characterization in materials science often require the use of (ultra) low temperatures. Many phenomena also involve the application of high magnetic fields, usually generated by superconducting magnets. attocube provides a broad portfolio of versatile cryostats for sensitive measurements at variable temperatures and extreme conditions.

Model 7650 -
Jinan Testing Equipment IE Corporation
Model 7650 extensometers are primarily used on round specimens tested in bi-axial test machines capable of simultaneous axial and torsional loading. All models are capable of bi-directional displacement in both axes and may be used for strain-controlled fatigue testing under fully reversed load and strain conditions at frequencies up to 10 Hz.All 7650 models mount rigidly on the load frame and incorporate slide mounting to bring the extensometer into contact with the specimen. The gauge length is set automatically before mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.These units are specifically designed to minimize crosstalk between axes and to provide high accuracy, high resolution measurements. They incorporate capacitive sensors for low operating force and include electronics with programmable filtering and multi-point linearization for improved performance and accuracy. The overall design minimizes, and in many cases virtually eliminates, any influence from common lab environment vibrations.These water-cooled extensometers are equipped with high purity alumina rods with conical rod tips for specimen contact when testing to 1200℃(2200°F). Silicon carbide rods are used for the 1600℃ (2900°F) high temperature option.

PITC -
Bemco Inc.
The PITC, with a temperature range of -70 C to +177 C, was first introduced in the late 1950s by Bemcos Conrad/Missimer Division. Today, the modernized version of this system is the ideal solution where short run or infrequent tests are required, test specimens are unusual in size or shape, initial capital costs must be held low, or test needs are frequently changed.

SKZ108 -
SKZ Industrial Co., Ltd
Burst tester is the basic instrument for testing the anti-bursting degree of paper or cardboard. For cardboard: It conforms to the standards of ISO2759 (standard testingfor cardboard bursting strength) and GB1539 (method for testing cardboard burstingstrength). For paper: It conforms to the standards of ISO2758. It adopts signal transmitting press. When the specimen is burst, the tester stores the maximum of bursting strength automatically.
