Sleeping Bag Systems for Children: Thermal Insulation and Temperature Ratings
ASTM F 1720 "Standard Test Method for Measuring the Thermal Insulation of Sleeping Bags Using a Heated Manikin" modified using child-size manikin
Child thermal manikin (boy’s size 8) on a cot in an environmental chamber
$600 for 3 replications
Heat transfer models based on children’s physiology at different ages are used with the insulation value to determine the temperature ratings for comfort during sleep. No additional charge for these calculations.
