About this file
This document is a Statement of Work (SOW) for a High Temperature Air Tension Tester issued by NASA's Glenn Research Center (GRC) in Cleveland, Ohio. The SOW details precise technical requirements for a sophisticated materials testing system capable of tension and compression testing of metallic samples at high temperatures up to 1500°C. Key components include a load frame with 100kN force capacity, an electrical actuator with 150mm displacement, a 10kN load cell, and two extensometer options (optical and contacting ceramic probe), along with a three-zone furnace with independent temperature control and specific thermal gradient specifications. The system must include compatible software operating on Windows 11, capable of creating custom test programs, running in closed-loop force and strain control, and exporting test data. NASA will provide utility connections and sample thread couplings, while the vendor is responsible for installation and initial configuration. The delivery location is the Glenn Research Center in Cleveland, Ohio, with a performance period of nine months from contract award.

CLEVELAND, OHIO
High Temperature Air Tension Tester
1. BACKGROUND
Glenn Research Center (GRC) High Temperature and Smart Alloys Branch has a requirement for a new test machine for testing metallic samples in air at high temperatures for materials development and maturation.
2. SCOPE
The vendor shall supply a system for tension compression testing samples in air at a high temperature which meets the following requirements:
Load Frame
a. The load frame shall be capable of applying equal or greater than 100kN of force to the sample in tension or compression.
b. The load frame actuator shall be electrically driven.
c. The load frame actuator shall be capable of equal or greater than 150mm of total displacement.
d. The load frame actuator shall be capable of velocities from 0.001 mm/sec or less to 10 mm/sec or greater at the full force rating of the frame.
Load Cell
a. A load cell shall be provided for both measuring the force exerted on the sample, as well as controlling the actuator in closed loop force control.
b. The quote shall include a load cell with a range of 10kN.
c. The load cell shall have an accuracy equivalent or better than as defined by ISO 7500-1 class 0.5.
Extensometer
a. An optical non-contact axial extensometer shall be provided for both measuring strain within the gauge section of a sample under test, as well as controlling the actuator in closed loop strain control (meeting ISO 6892-1 and ISO 6892-2 method A1).
b. The frequency of measurement of the optical extensometer shall be greater than 50Hz, with a latency of measurement to control output less than 20ms.
c. The optical extensometer shall be capable of measuring samples which are at 1500C inside the furnace described below.
d. The optical extensometer shall be capable of measuring samples with initial gauge length of 12.7mm, and be capable of measuring from -10% to +50% or greater strain.
ATTACHMENT A
e. The optical extensometer shall be capable of tracking samples moving at up to 500 mm/min or greater.
f. The optical extensometer shall have a spatial resolution of 1μm or less.
g. A contacting ceramic probe axial extensometer shall be provided as an alternate method of measuring/controlling strain.
h. The contacting extensometer shall have an adjustable contact force of 100g force or less.
i. The contacting extensometer shall be capable of measuring samples at 1500C inside the furnace described below. To accomplish this, a suitable mounting fixture and suitable length ceramic probes are required.
j. The contacting extensometer shall have an initial gauge length of 12.7mm, and a range of at least -10% to +50% strain.
k. The contacting extensometer shall be read by the control / data acquisition system at a digital resolution of 24 bits or greater.
l. The contacting extensometer shall have a fixture which automatically sets the initial gauge length while mounting to a sample which is already at high temperature (hot mountable).
Furnace
a. A furnace shall be included for the purpose of high temperature air testing.
b. The furnace shall be capable of heating a sample to 1500C or greater.
c. The furnace shall have a hot zone of 254mm in height or greater.
d. The furnace shall have openings at the top and bottom of 30mm or greater for sample fixturing.
e. The furnace shall have an opening(s) for extensometry compatible with all provided extensometers (Intent being to utilize either optical extensometry or probe extensometry, not necessarily both simultaneously).
f. The furnace shall be comprised of 3 independently controlled heating zones for the purpose of minimizing the thermal gradient of the sample under test to within ±2K.
g. The furnace zones shall be controlled by a closed loop controller utilizing type-R or type-S thermocouples. This controller shall be capable of computer control via either serial (RS232 or RS485) or ethernet and utilizing the MODBUS protocol.
h. The 3 furnace control thermocouples shall be mounted via an adjustable spring loaded fixture which pushes each thermocouple tip into direct contact with the gauge area of the sample under test.
i. The thermocouple fixture shall pivot to allow the contacting thermocouples to maintain contact with a sample as it deforms over the duration of a test with a minimum separation of 6±mm and a maximum separation of 50±mm.
j. The control thermocouples shall be ceramic sheathed with open tips to enable direct contact between the thermocouple junction and the sample.
k. The furnace shall be capable of heating at a rate of 10C / min or greater.
Fixturing
a. A fixture for tension testing metallic threaded round samples at temperatures up to
1200C shall be provided.
b. Fixture / pull rods shall be rated for 5kN or greater with a sample temperature of 1100C.
c. Pull-rods shall attach to the load frame utilizing a self-aligning coupling (ie: spherical joint or universal joint)
d. Pull-rod hot ends shall be terminated in a ¾-10 UNC external thread. NASA will provide Mar-M thread couplings to couple threaded samples to the pull-rods.
