GB/T 39605-2020Test method for measuring the evaporative resistance of clothing—Sweating manikin method (English PDF)

1 Scope

This standard specifies the terms and definitions, test principles, test equipment, test procedures, and moisture resistance of the sweat-heating manikin to test clothing moisture resistance

Calculation and test report:

This standard is applicable to the moisture resistance test of a whole set of clothing in an upright and static state: Separate moisture resistance test for top or bottom and different wind

The tests of clothing moisture resistance under speed, human posture and movement speed can all be implemented by reference:

3 Terms and definitions

The following terms and definitions apply to this document:

3:1

Whole set of clothing clothingensemble

A set of clothing worn on a dummy in a certain order:

3:2

Clothing area factor fcl

The ratio of the surface area of the dummy before and after dressing:

3:3

Sweating manikin

It imitates the body shape of the human body, has sweating and heating functions, and can measure the person's heat dissipation through the dry state and evaporation of the clothing under steady-state conditions

Body model:

Note: Steady-state conditions refer to constant sweat rate, heat flow, and temperature difference between the human body surface and the external environment:
