To enable labelling of the sleeping bag, the inside length of the sleeping bag shall be measured within±3 cm. The measurement is made by turning the sleeping bag inside out and measuring the length from the position of the seam where the heel of the foot is placed to the top of the sleeping bag (excluding any vertical components of the hood), without applying any force to extend the sleeping bag length.
To enable labelling of the sleeping bag, the maximum inside width shall be measured within±2 cm. The measurement is made by turning the sleeping bag inside out and measuring the circumference at the widest point without stretching the fabric. If the maximum inside width of the sleeping bag is not in the chest area, then the position of the widest point of the sleeping bag shall be indicated on the label. The circumference is halved to provide the width of the sleeping bag. If the sleeping bag has elastic seams,a force of(10±1) N may be used to extend these seams prior to measurement, for instance by using a spring balance.
To enable labelling of the sleeping bag, the foot width shall be measured within ±2 cm. The measurement is made by turning the sleeping bag inside out and measuring the circumference at a distance (30±1) cm towards the hood from the position where the heel of the foot is placed. The circumference is halved to provide the width of the sleeping bag. If the sleeping bag has elastic seams, a force of (10±1) N may be used to extend these seams prior to measurement, for instance by using a spring balance.
The thermal resistance posture 2 Rc(2) is measured with the thermal manikin only partly inserted into the sleeping bag, and lying on its back. The upper part of the sleeping bag is pulled up only to the thermal manikin’s arm pits; and the arms of the thermal manikin lie outside the bag’s upper part. The zippers of the sleeping bag, if any, are completely opened. The bag’s hood, if present, is placed below the thermal manikin’s head without tightening the cords. No cold-protective mask is on the thermal manikin’s face.ISO 23537-1 pdf free.
