ASTM D882 -
National Technical Systems
This test method covers the determination of tensile properties of plastics in the form of thin sheeting and films (less than 1.0 mm (0.04 in.) in thickness). Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.25 mm (0.010 in.). Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined according to Test Method D638. This test method can be used to test all plastics within the thickness range described and the capacity of the machine employed. Specimen extension can be measured by grip separation, extension indicators, or displacement of gage marks. The procedure for determining the tensile modulus of elasticity is included at one strain rate. The modulus determination is generally based on the use of grip separation as a measure of extension; however, the desirability of using extensometers, is recognized and provision for the use of such instrumentation is incorporated in the procedure. Test data obtained by this test method is relevant and appropriate for use in engineering design. The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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.

68CB6 -
North Atlantic Industries
The 68CB6 is a Configurable Open Systems Architecture™ (COSA®) 3U OpenVPX™ board that is preconfigured with 10 different “inboard” I/O, measurement and communication functions. This Combination-function Board (CB) provides a full suite of some of the most common & useful function interfaces supporting many different applications. The 68CB6 features a wide but dedicated selection of functions: Standard Functionality Discrete I/O (DT1); Successive Approximation Register (SAR) ±100 V Analog-to-Digital (AD); Isolated High Voltage Analog-to-Digital (ADF); ±10 V Digital-to-Analog (DA); Thermocouple (TC1) or Resistance Temperature Detector (RT1); Full-bridge Strain Gauge (SG1); Transmission/gear box Chip Detection and Fuzz Burn (CD1); LVDT-to-Digital linear (LD6) displacement (position) measurement, AC Reference Source output (AC2); CAN bus communication (CB8). The 68CB6 offers unparalleled programming flexibility, a wide range of operating characteristics, and a unique design that eliminates the need for external intermediate circuit considerations such as pull-up resistors or mechanical configuration jumpers. Inboard functions are software controlled and memory addressed, accessed in similar COSA® modular fashion to maintain seamless common NAI Software Support Kit & API/library structures.
