New Test Method for Standard Test Method for Measuring the Radiant and Contact Conductance of Boot Assemblies Worn on Extravehicular Activities
1. Scope
1.1 This test method covers the determination of the conductance of boots assemblies used in extravehicular activities. It describes the measurement of heat transfer from a heated foot to extreme radiant and conductive environments within a vacuum.
1.1.1 This is both a static and compressive test that provides a boot assembly measurement using an instrumented foot.
1.1.2 The effect of foot movement and posture are not addressed in this test method.
1.2 This test method covers the determination of the conductance in a radiative state and the conductance of key areas of the boot assembly when compressed against a thermal conditioned object.
1.3 The measured conductance in the radiant case and compressive state applies only to the boot assembly evaluated and for the reported environmental and compressed conditions.

Rationale
New standard to understand the protective properties of a boot assembly that could be worn in space without a human in the loop.
