SAE J 2432
Performance Testing of Belts
The purpose of this standard is to provide methods to evaluate the performance and quality of belt construction.

ARDL Has the Test Stands For:
     • Section 4 - High Temperature - Constant Tension Testing
     • Section 5 - Hot & Cold Cycling Testing
     • Section 7 - High Temperature, Flex Testing and Low Temperature Cycling Testing
     • Dynamic Testing on an MTS unit is also available

SAE 4-Pulley Hot/Cold Set-Up
     • Thermotron Chamber: -93ºC to 176ºC
     • Baldor Drive Unit: 3 HP, 6,000 RPM
     • Hot or Cold Start & Stop Sequencing
     • Constant Tensioning Fixture
     • Cold Cycling at -43ºC with Nine Intermittent Start and Stop Cycles
       (1 hr, 25 min, 10 sec)
     • Hot Cycling at 121ºC with Constant RPM for 48 hours.

SAE 5-Pulley Set-Up
     • Constant Tensioning Fixturing
     • Constant 3,900 RPM and Tension with Increasing Temperatures
     • Measure Weight and Length
     • Temperature Raised Every 50 Hours
     • Starting Temperature 100ºC
     • Increase of Temperature -12ºC after each Interval Check
     • Final Chamber Temperature = 115ºC
     • Total Test Time = 200 Hours
     • Test Flexibility Under High Temp/Speed
     • Baldor Drive Unit: 1 HP, 6,000 RPM

     • 100 Cycles per Belt (If there are no visible defects, the temperature is lowered
       and the belt is soaked for 30 min per cycle)
     • Belts are Soaked for 8 Hours Before the Beginning of Testing

Belt Length Measuring Fixture
     • Wide Variety of Initial Belt Lengths
     • Variable Measuring Force
