Standards Development

Scope

This document specifies a test method for the determination of heating performances of wearable electric heating textile products. Wearable heating textile products are made of e-textiles parts including a movable battery for electric heating and conventional textiles parts for garments such as jackets, jumpers, etc. This document includes the test procedure for the heating temperature and power consumption of wearable heating textile products. This document is not applied to household electrical heaters and medical devices.

Purpose

This standard provides a method for determining the heating performance of wearable heating textile products.

Wearable heating textile products are the most popular item and have the highest portion of the e- textile market. Heating textile products are widely used in commercial markets and have a mature value chain.

Wearable heating products are made of e-textiles and conventional textiles. E-textile parts produce heat, and conventional textile parts keep the generating heat from the cold environment. It helps the wearer maintain a comfortable body temperature, especially during activities in cold weather conditions.

Wearable heating textile products are used for activities in cold environments such as winter sports, cold storage workers, military forces, and recently covid-19 healthcare workers, and so on.

Wearable heating textile products are mostly outer garments such as jumpers and vests, and recently gloves and socks are also developed. From the market analysis reports, heating jackets currently account for 0.5% share of the global winter wear market, with the market expanding at a high CAGR of 16%.

Consumers have been interested in product performances such as heating temperature and duration. However, due to the absence of a standardized test method, consumers and manufacturers have been in difficulties recognizing or comparing each product objectively.

The main principle of this test method is to measure the heating temperature after confirming the heating part with IR thermography and to measure power consumption simultaneously.

Through this test method, it is expected to provide correct information to customers and manufacturers.
