Dynamic mechanical thermal analyzer

Added: Aug 03, 2017 9:46 am Requirement specification for dynamic mechanical thermal analyzer

Force and displacement
• Force measurement to 15 N with 0.01% of full scale resolution
• At least 25 mm of travel
• Transient (stress relaxation, creep/recovery) as well as dynamic measurement
• DMA frequency range of 0.01 to 200 Hz
• Adjustment of static tension during temperature scans to avoid specimen buckling
• Tan δ sensitivity of at least 10-4

Temperature/ Environmental
• Operation from -150 °C to 600 °C
• Isothermal measurement or scanning at 0.1 to 20 °C/min under software control
• Ability to run test in an inert gas environment

Fixturing/Modes of Operation
• Fixturing for measurements in tension, shear, cantilever bending, 3-point bending, and compression shall be supplied

Software
• Machine shall be operator programmable to perform temperature, frequency, and strain sweeps, as well as, transient measurements
• Conversion of raw data to stress, strain, compliances/moduli, and loss tangent
• Real-time display of specified measured and calculated values
• Archiving of data and test conditions and exporting as plain text
• Graphing with user-selectable scaling and post-processing of data to identify thermal transitions and perform shifting (e.g. time-temperature superposition) and print results

Computer (equivalent to NASA standard desktop)
• Intel Core i5-2400 3.1 GHz
• 4 GB Ram
• 500 GB Hard Disk
• 23" LCD monitor
• CD-RW drive or better

Utilities
• Shall operate on 110-220 V ac
• Up to 15 amp
• Other requirements (e.g. compressed air, vibration isolation, etc...) must be clearly stated

Accessories
• Vendor to supply turnkey system including environmental chamber, dewar, all fixtures, cables, hoses, instructions, training manuals, computer and software.
• At least one day of instrument installation and training
