static dissipative (sd) footwear:抗靜電（抗静电安全鞋）

5.6.1 static dissipative footwear shall also meet the requirements of 5.1 for impact resistance footwear and 5.2 for compression resistance footwear.

5.6.2 static dissipative footwear shall be designed, constructed, and manufactured to provide protection to the wearer against hazards which may exist due to excessively low footwear resistance in a work environment, as well as maintain a sufficiently high level of resistance to reduce the possibility of electrical shock ion work areas where SD footwear is worm.

5.6.2.1 footwear shall reduce the excess static electricity by conducting the charge (from body) to ground whole simultaneously maintaining a sufficiently high level of resistance (10⁶ ohms) (1megohm) to protect the wearer when exposed to hazards from incidental contact with live electric circuits.

5.6.2.2 using human subjects, a pair of footwear shall have a lower limit of electrical resistance of 10⁶ ohms (1megohm) and have an upper limit electrical resistance of 10⁸ ohms (100megohms).

5.6.3 the workmanship in the production and assembly of the footwear shall ensure that the footwear provides functionality to the wearer.

5.6.3.1 the footwear shall use any combination of materials that facilitate static dissipation by a consistent path of resistance.

5.6.3.2 the inconsistency of certain hygroscopic materials can result in footwear not being able to consistently meet the performance requirements of static dissipative footwear.

5.6.3.3 heels shall be attached using non-ferrous heel nails, these nails shall be recessed within the tread surface and then covered with conductive material, these nails shall be neither exposed nor visible.

5.6.4 static dissipation shall be determined by evaluating the minimum number of specimens per lot size in accordance with test methods F2412.

5.6.4.1 any specimen that does not meet the performance requirement constitutes a failure for the lot.
