Standard Practice for Determining the Temperature Ratings for Cold Weather Protective Clothing

Importancia y uso:

4.1 This practice is used to measure the insulation provided by a cold weather clothing garment or garment system using a heated manikin (see Test Method F1291) and to predict the temperature rating for comfort at two activity levels using whole-body heat loss models.

4.1.1 The temperature rating is for an ensemble—not an individual garment. However, manufacturers want to label cold weather garments or garment systems with a temperature rating to help consumers select the product that will best meet their needs. Therefore, the insulation of a garment or garment system is measured with a standard base ensemble. Furthermore, the standard is limited to garments that cover a substantial amount of body surface area such as jackets, coats, insulated pants, coveralls, or snow suits. The temperature ratings of headwear, footwear, and handwear cannot be determined with this practice.

4.1.2 The temperature predictions determined by this standard practice are for adults only. The physiology of children is significantly different from that of adults, so a modified heat loss model needs to be used to predict the comfort of children wearing outdoor clothing.5

4.1.3 The temperature ratings determined by this standard practice and listed on garment labels are only guidelines for comfort and will be affected by the garments consumers wear with them, their activity level during wear, and individual differences in the physiological characteristics of people (for example, gender, age, body mass, etc.).
