Standard Performance Specification for Conductive Clothing for Industry Applications

Importancia y uso:

5.1 This performance specification identifies electrical, thermal, and mechanical performance characteristics for conductive clothing and its components.

5.1.1 The measured data provides information that the buyer can use when selecting conductive clothing used in Type 1 (for example, barehand work, hot stick live work), Type 2 (for example, ac induction) and Type 1 plus 2 (for example, barehand and hot stick live work, and ac induction) applications.

5.1.2 Type 1 clothing consists of a conductive garment (coverall, jacket and pants, or jacket and bib), and other mandatory and optional components. Mandatory components include conductive gloves, socks, or footwear, headcover and bonding lead. Optional components may be required to meet this performance specification which may include a face cover or face mesh or face screen.

5.1.3 Type 2 clothing consists of a conductive garment (coverall, jacket and pants, or jacket and bib), and other mandatory components. Mandatory components include conductive gloves, socks or footwear, and headcover.

5.1.4 Type 1 plus 2 clothing consists of a conductive garment that meets both Type 1 and Type 2 requirements.

5.1.5 The users of this standard can incorporate the information in this specification for purchase contracts to ensure that the quality controls used for the manufacturing of the conductive clothing will meet the performance requirements identified in this standard.

5.2 The selection and use of any conductive clothing requires an assessment by the worker and supervisory personnel of hazards in the work site. Ongoing risk assessment and work methods performed by workers shall mitigate the hazards.

5.2.1 Type 1 clothing shall be used on systems with a nominal voltage that is equal or lower than the maximum allowable voltage reported on the clothing label.

5.2.2 Type 2 clothing shall be used on systems where the estimated ac induction current magnitude (in amperes) and duration (in seconds) do not exceed the label rating.

5.2.2.1 Type 2 clothing is recommended for systems where the ac induction current magnitude exceeds 50 A. Although the clothing does not guarantee full protection, it can still significantly reduce the physiological effects.

5.2.3 The end user purchasing conductive clothing is responsible to prepare complete and detailed instructions and policies regarding the use of the conductive clothing. This includes risk assessment of hazards, work practices, controls, and use of equipment.

5.3 This specification applies to all the components in a conductive clothing kit (for example, hood, face screen, jacket, bib, coverall, bonding accessories, gloves, socks, footwear).

5.3.1 See examples of Type 1 clothing in Fig. 1.
