14、 used over time to designate that an electronic component, device, or item is susceptible to some level of ESD damage, the most recognized symbol is a triangle around a reaching hand that is covered by a diagonal slash. Another symbol is used to designate that a material, item or product has some el

15、ectrostatic control property as defined by the manufacturer. The protective symbol has a hand inside a triangle without the slash across the hand. An arc is placed around the outside of the triangle to suggest the idea of protection. A third symbol is used to mark the location of a common point grou

16、nd. These three symbols have been in wide use since the early 1990s and have gained acceptance globally. The symbols have been used by military and commercial organizations and appear in international standards related to electrostatic control. This standard1 was originally designated EOS/ESD S8.1-1

17、993 and approved on June 9, 1993. ANSI/ESD S8.1-2001 was a reaffirmation of EOS/ESD S8.1-1993 and was approved on September 9, 2001. ANSI/ESD S8.1-2007 was a reaffirmation of ANSI/ESD S8.1-2001 and was approved on September 16, 2007. ANSI/ESD S8.1-2012 is a revision of ANSI/ESD S8.1-2007 and was app

18、roved on June 10, 2012. ANSI/ESD S8.1-2017 is a revision of ANSI/ESD S8.1-2012 and was approved on December 7, 2016.

27、s Symbols ESD Awareness 1.0 PURPOSE AND SCOPE 1.1 Purpose The purpose of this document is to standardize commonly available and in-use symbols and to clarify the meaning of each of these symbols. The correct usage of symbols will eliminate confusion between symbols that indicate that an item or mate

28、rial is ESD susceptible and those that indicate that an item is designed to afford some degree of ESD protection. This symbol standard is developed in accordance with international graphical guidelines and standards. 1.2 Scope Three symbols are covered in this document. The first indicates that an e

29、lectrical 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 indica

30、tes 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. 2.0 REFERENCED PUBLICATIONS Unless otherwise specified, the fol

33、 point ground. A grounded device or location where the conductors of one or more technical elements are bonded. 2 EOS/ESD Association, Inc., 7900 Turin Road, Bldg. 3, Rome, NY 13440; Ph: 315-339-6937; www.esda.org ANSI/ESD S8.1-2017 2 4.0 ESD SUSCEPTIBILITY SYMBOL The ESD susceptibility symbol incor

34、porates 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 be

35、ing 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 incorp

36、orated 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

37、1A. Figure 1A: ESD Susceptibility Symbol When it is necessary to shrink the symbol due to the size of the item on which the symbol is placed, all detail possible should be included in the symbol. This symbol should not be decreased in size to less than 12 mm x 12 mm (0.5 inch x 0.5 inch), except in

38、cases where available space is severely limited. See Figure 1B. Figure 1B: Size Constraints for ESD Susceptibility Symbol ANSI/ESD S8.1-2017 3 This symbol may incorporate an alphanumeric character to indicate the ESD sensitivity (ESDS) classification of the device or assembly. These classifications

39、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. Figure 1C: ESD Susceptibility Symbol with Component Classification 4.2.1 Color T

40、he 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

41、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 gr

42、ounding 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 ES

43、D 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. ANSI/ESD S8.1-2017 4 5.2 Format The symbol is a reaching hand with defined fingers and fingernail, in a contrasting triangle, surrounded by a

44、 bold arc. See Figure 2A. Figure 2A: ESD Protective Symbol When it is necessary to shrink the symbol due to the size of the item on which the symbol is placed, this symbol may be simplified as a function of the size. All detail possible should be included in the symbol. This symbol should not be dec

45、reased in size to less than 12 mm x 12 mm (0.5 inch x 0.5 inch), except in cases where available space is severely limited. See Figure 2B. Figure 2B: Size Constraint for ESD Protective Symbol The ESD protective symbol may be printed, embossed, hot stamped, silk screened, or incorporated through othe

46、r mechanisms. In addition to the symbol, the manufacturers name, date of manufacture, or lot date code may be included where applicable. See Figure 2C. Figure 2C: ESD Protective Symbol with Identification 5.2.1 Color The color red shall not be used because it suggests a hazard to personnel. The pref

47、erred color is a yellow hand on a black background with a black arc. ANSI/ESD S8.1-2017 5 6.0 ESD COMMON POINT GROUND SYMBOL This symbol is established to indicate an ESD common point ground, which is described in ANSI/ESD S6.1. 6.1 Application The ESD common point ground symbol should be used to in

48、dicate the location of an acceptable common point ground as described in ANSI/ESD S6.1. 6.2 Format This symbol consists of a bold outer circle inside of which are the words ESD COMMON POINT GROUND, in bold type. Inside of that are two thick contrasting circles and one thick circle that may fill the

49、center or extend to the center where a snap, plug or other fastener may be connected. See Figure 3A. Figure 3A: ESD Common Point Ground When it is necessary to shrink the symbol due to the size of the item on which the symbol is placed, this symbol may be simplified as a function of the size. All detail possible should be included in the symbol. This symbol should not be decreased in size to less than 12 mm x 12 mm (0.5 inch x 0.5 inch), except in cases where available space is severely limited. See Figure 3B.
