BS EN ISO 23537-1:2022 PDF Download

The specifications, test procedures, and labeling guidelines for adult-sized sleeping bags intended for use in sports and leisure activities at limit temperatures of -20 °C and higher are outlined in the BS EN ISO 23537-1:2022 standard. The standard focuses on evaluating these sleeping bags' thermal properties, size, and mass.

The evaluation of the sleeping bag's performance under steady-state settings to ascertain its ability to guard against cold is one important topic covered by the standard. It offers guidelines and instructions for carrying out tests to judge the sleeping bag's insulating properties.

It's important to note that the standard recognizes that testing and calibration techniques might be challenging for sleeping bags with non-homogeneous contents, which are intended to give additional local insulation in specific areas. The development of appropriate methods for determining temperature ratings for these sleeping bags is still under way.

It's crucial to remember that the standard does not apply to sleeping bags made for specific uses, like military use and excursions in extremely harsh climates. Additionally, it excludes sleeping bags made for infants or children. This is due to the lack of a prediction model that can currently be used to calculate the limiting temperatures using the thermal resistance of sleeping bags for infants and babies. Furthermore, it is unethical to conduct controlled sleep experiments on infants or children in climate-controlled environments, which makes the creation of such a testing model impossible.
