Introduction

Standard, EN 13537. This is the first edition of this part of ISO 23537. It is based on continued development of the European This International Standard consists of two parts which allows for separate validation of thermal properties and product and material performance. This separation of parts also allows for continued development of new product combinations as it encourages manufacturers to consider new tests, but which can still have thermal properties evaluated. combinations of materials which for example might not be suitable to test by traditional textile physical This part of ISO 23537 considers important aspects to the thermal performance of the sleeping bag. During the development of this part of ISO 23537, consideration was given to the need to continue to tightened as a consequence. reduce inter laboratory variability of the thermal testing and a number of test parameters have been

Consideration has also been given to the definition of extreme climate zone which is now referred to as temperatures <−20 °C.
