1.1 This test method covers determination of the insulation value of a single garment or a clothing ensemble. It describes measurement of the resistance to dry heat transfer from a constant skin temperature manikin (with a human skin temperature pattern) to a relatively calm, cool environment.

1.1.1 This is a static test that provides a baseline clothing measurement on a standing manikin.

1.1.2 The effects of body position and movement are not addressed in this test method.

1.2 The insulation values obtained apply only to the particular garments, as tested, and for the specified thermal and environmental conditions of each test, particularly with respect to air movement, are not addressed in this test method.

1.2.1 the insulation values obtained apply only to the particular ensembles evaluated and for the specified thermal and environmental conditions of each test, particularly with respect to air movement past the manikin.

1.3 The values stated ineither clo or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the test method.
