本标准不涉及因添加含有放射性物质的材料而激发出空气中负离子的纺织产品的安全性评价。

1 Scope

This standard specifies the test method for measuring the negative-ion concentration in textiles by friction method, and gives the evaluation.

This standard applies to various textiles and their products.

This standard does not involve the safety evaluation of textile products that excite negative ions in the air due to the addition of materials containing radioactive substances.
