ANSI ESD S8.1 pdf free download.For the Protection of Electrostatic Discharge Susceptible Items – Symbols – ESD A wareness.
1.2 Scope
Three symbols are covered in this document. The first indicates that an electrical or electronic device or assembly is susceptible to damage from an ESD event if not properly handled. The second indicates that the material or product on which the symbol is displayed is intended to provide some level of protection to ESD susceptible devices or assemblies. The third indicates the location of an ESD common point ground terminal or connection point.
The application of these ESD symbols on products is at the discretion of the supplier and does not constitute or imply a specific level of product performance.

3.0 DEFINITIONS
The following definition shall apply for the purposes of this standard in addition to those specified in the ESD Association Glossary of Terms, available for complimentary download at www.esda.org:
common point ground. A grounded device or location where the conductors of one or more technical elements are bonded.
4.0 ESD SUSCEPTIBILITY SYMBOL
The ESD susceptibility symbol incorporates a reaching hand in a triangle with a slash through it and is used to indicate that an electrical or electronic device or assembly is susceptible to damage from an ESD event.
4.1 Application
The ESD susceptibility symbol should be used on assemblies and devices that have been identified as being sensitive to ESD events.
The symbol shall not be used on materials designed for use in ESD protective areas, such as smocks, seating, worksurface materials, tools and equipment, packaging materials, or personnel grounding equipment. Refer to Section 5.0 of this standard.
The symbol may be incorporated on a sticker, label or seal used to close ESD protective packaging in order to indicate that materials inside the package are ESD susceptible.
4.2 Format
The symbol is a reaching hand with defined fingers and fingernail, in a contrasting triangle with a slash in front of the hand. See Figure 1A.
This symbol may incorporate an alphanumeric character to indicate the ESD sensitivity (ESDS) classification of the device or assembly. These classifications should be in accordance with the ESD Sensitivity Components Classification of the referenced test standard. The ESDS classification, if used, should be placed in the central area of the symbol as indicated in Figure 1C.
4.2.1 Color
The color red shall not be used because it suggests a hazard to personnel.
The preferred color is a yellow hand and slash on a black background.
5.0 ESD PROTECTIVE SYMBOL
The ESD protective symbol differs from the ESD susceptibility symbol by the addition of an arc around the outside of the triangle and the omission of the slash across the hand and the triangle.
5.1 Application
The ESD protective symbol may be used to identify items that are specifically designed to provide ESD protection for ESDS assemblies and devices. Examples of these are packaging, ESD protective clothing, and personnel grounding equipment such as wrist straps, footwear, and footwear grounding devices. The ESD protective symbol may also be used on items designed to replace static generative materials. Examples of these items are ESD protective work station equipment, trash can liners, and chairs. The item is to be ESD protective or non-static generative by design.
The symbol shall not be used on ESD susceptible devices or assemblies. Refer to Section 4.0 of this standard.
