Technical Data Sheet
Specific gravity: 1.35 max (ASTM D882, Sections 73-74)
Shrink Temperature: 194F to 248F(90C to 120C)
Corrosion: Non-corrosive (ASTM D2671, Sections 93-95, Procedure A)
UV Resistance: The samples were tested in a QUV weather tester as per test procedure ASTM G-154.
Observations made at *3000 hours exposure showed no loss in legend or change in
material.
*3000 hours equates to 5 years of assimilated outdoor UV exposure.
Fluid Resistance: Tubings tested in the following fluids per ASTM D2671 Sections 63-67
Hydraulic Fluid MIL-H-5606
JP8 - MIL-T-5624
OIL - MIL-L-7808
OIL - MIL-L-23699
5% NaCl - A-A-694
Deicing Fluids – MIL-A-8243
After immersion test:
Tensile Strength - 6.89 MPa (1000 psi) minimum per ASTM D2671 Sections 44-48
Ultimate Elongation - 100% minimum per ASTM D2671 Sections 44-4
PROPERTIES FOR SOLAR
APPLICATION:
PERFORMANCE:
Short term temperature exposure: 30 days at -51C, no visible change observed
Short Term high temperature exposure: 30 days at 93C, no visible change observed
Relative Lightfastness and weatherability: 1000 hours, slight fade in color observed (ASTM D3424, Method 4)
Tensile Strength: MD: 1158 PSI (ASTM D3759)
Elongation: MD: 510% (ASTM D3759)
Marking Performance:
SAE-AS5942: Samples were tested heat shrunk. Print still legible after 20 eraser rubs with hard hand pressure.
MIL-STD-202G: Method 215K, Solution A, C, and D: 3 cycles of 3 minute immersions in specified fluids
followed by toothbrush rub after each immersion. Print still legible in all test fluids.
MIL-STD-883F: Method 2015.13, Solution A, B and D: 3 cycles of 1 minute immersion in specified fluids
followed by toothbrush rub after each immersion. Print still legible in all test fluids.
Nuclear Plant (Class 1E) Harsh Environment Test Result Summary
GMUHS31 heat shrink tubing has been tested for use as an identification marker for use in harsh environments in various nuclear
power plants. Printed markers were subjected to radiation exposure, thermal aging and LOCA/MSLB environmental testing as shown
in the three tables below. Test margins related to IEEE 323-2003 were used.
