Telecordia GR-468-CORE for optoelectronic systems
Is test 5.20 thermal cycling or thermal shock? 5.20 states: The procedure should agree with Method 1010 of MIL-STD 883C, with a minimum temperature ramp rate of 10°C/min.", which makes it sound like a chamber capable of only 10°C/min. is required.
"3.1 Timing. The total transfer time from hot to cold or from cold to hot shall not exceed one minute. The load may be transferred when the worst case load temperature is within the limits specified in table I. However, the dwell time shall not be less than 10 minutes and the load shall reach the specified temperature within 15 minutes." (Mil-Std 883 method 1010.7)
Either way you read the test, the Thermal Shock Chambers is still your best choice for doing this test with the smallest chamber and least resources required.
