14、FOREWORD This standard practice1is intended to provide test procedures for measuring the intrinsic electrical resistance of gloves and finger cots; as well as the electrical resistance of gloves or finger cots and personnel together as a system. This standard practice applies to all gloves and finge

15、r cots used to control Electrostatic Discharge (ESD). This standard practice provides data that are relevant in the users specific environment and application. The test uses ANSI/ESD STM11.11, Surface Resistance Measurement of Static Dissipative Planar Materials, ANSI/ESD STM 11.12, Volume Resistanc

16、e Measurement of Static Dissipative Planar Materials, ANSI/ESD STM 11.13, Two-Point Resistance Measurement of Dissipative and Insulative Materials and a Constant Area and Force Electrode (CAFE) specifically designed for resistance measurements at the thumb and finger-tips. A further advantage of the

17、 CAFE is that it can be used to test finger cots as well as gloves using an identical procedure. The user of the CAFE test method should note that the in-use resistance of the glove or finger cot can be much lower than its intrinsic resistance as measured by ANSI/ESD STM11.11, STM11.12, or STM11.13.

18、 In addition, once a glove or finger cot is worn it can be measured only once because the glove or finger cot may be contaminated by a persons skin emissions. This contamination could affect the accuracy and reproducibility of further measurements on a particular glove or finger cot. It is suggested

19、, for the best reproducibility for a test group, that gloves or finger cots be selected from the same lot. In the case of testing for lot-to-lot product auditing, compliance verification or variation, gloves or finger cots should be selected from multiple lots. Electrical resistance is one property

20、that can be used to evaluate the electrostatic characteristics of gloves. However, resistance does not fully characterize these materials. An additional property to be considered in the selection and use of gloves and finger cots includes charge accumulation. Suggested test methods for personnel and

21、 glove and finger cot charging will be forthcoming. A common source of electrostatic charge in a work environment is the separation of gloves from the items being picked-up or released, resulting in the generation of electrostatic charge that can accumulate on personnel, gloves or finger cots and in

22、duced into items. The effect of this generation and accumulation of electrostatic charge can be minimized with appropriate selection of glove or finger cots. To effectively control electrostatic discharge on personnel and equipment, gloves and finger cots must be used in combination with other groun

23、ding devices. A glove material, which is conductive enough to discharge a person or an object, may also pose a safety hazard. The work performed on an ESD susceptible item often entails the use of tools and test instruments that operate at voltages high enough to cause electrical shock. The presence

24、 of a material tested using the methods described in this document will not guarantee personnel safety. This document includes test methods that may be applicable for measurement of gloves and fingers cots that reside in the conductive range, however, effects due to skin resistance and electrode res

25、istance may create significant errors. Test voltage may also be an issue for conductive materials. Beneficial comments (recommendations, additions, deletions and pertinent data), which may be of use in improving future versions of this document, should be addressed to ESD Association, Chairperson Su

27、i This standard practice was originally approved on September 11, 2005 and was designated ANSI/ESD SP15.1-2005. This standard practice is a reaffirmation of ANSI/ESD SP15.1-2005 and was approved on February 13, 2011. Two editorial changes were made from the 2005 version. The definitions were removed

28、 from Section 3.0 and users were referred to the website for a complimentary download. Also, “wrist cuff” was replaced with “wristband” to align with ANSI/ESD S1.1.

36、e Items In-Use Resistance Measurement of Gloves and Finger Cots 1.0 PURPOSE AND SCOPE 1.1 Purpose This document provides test procedures for measuring the intrinsic electrical resistance of gloves and finger cots, as well as their electrical resistance, together with personnel as a system. The syste

37、m test provides data that are relevant to the users specific environment and application. 1.2 Scope This document applies to all gloves and finger cots used as part of a user defined Electrostatic Discharge (ESD) Control Program. This document is intended to provide test procedures for measuring the

38、 electrical resistance of gloves or finger cots. Intrinsic resistance measurements include surface, volume, and point-to-point resistance using ANSI/ESD STM11.11, STM11.12, and STM11.13, respectively. “In-use” resistance measurement of the glove/finger cot and personnel together as a system is defin

39、ed using a constant area force electrode (CAFE). The resistance of the glove or finger cot may be much lower during use than its intrinsic resistance due to the interior of the glove/finger cot becoming hydrated once it is placed on the hand/finger of the operator. 2.0 REFERENCED PUBLICATIONS ESD AD

44、 315-339-6793; www.esda.org ANSI/ESD SP15.1-2011 2 Electrical hazard reduction practices should be exercised and proper grounding instructions for equipment should be followed. 5.0 EQUIPMENT 5.1 A wrist strap with a ground cord containing an integral one megohm resistor. Since an integral one megohm

45、 resistor is included in series with the wrist strap, the actual lower limit for the resistance measurement using this ground cord will be in the single-digit megohm range. The integral one megohm resistor should be verified using the test method described in ANSI/ESD S1.1. 5.2 A wrist strap with a

46、ground cord that does not contain an integral one megohm resistor. 5.3 Low Resistance Meter A DC ohmmeter shall be used for gloves that have intrinsic or in-use resistances less than 1.0 x 106ohms. The DC ohmmeter shall be capable of measuring a DC resistance of 0.1 ohm through 10 megohms 10% with a

47、n open circuit voltage greater than 1.5 volts and less than 10 volts. 5.4 High Resistance Meter 5.4.1 The meter shall have an output voltage of 100 volts ( 5%) while under load for measurements of 1.0 x 106 ohms and above, and 10 volts ( 5%) while under load for measurements less than 1.0 x 106ohms.

48、 5.4.2 The meter must be capable of making measurements from 1.0 x 103ohms ( 10% accuracy) to 1.0 x 1011ohms ( 10% accuracy). A power supply and ammeter, or an integrated instrument that combines those functions may be used. 5.5 Constant Area and Force Electrode (CAFE) The electrode design, material

49、s, and specifications are shown in Figure 1. 6.0 MATERIAL TESTING 6.1 Sample Size Six specimens of each glove or finger cot type are required for this test procedure. 6.2 Sample Preparation 6.2.1 Standard test conditions for this testing will be 23 3C, 12% 3% R.H. and 50% 5% R.H. 6.2.2 The samples shall be conditioned at the standard conditions for 48 hours minimum. 6.3 Surface and Volume Resistance Measurements of Glove Material The resistance of glove material shall be conditioned and tested using ANSI/ESD STM11.11, Surface Resistance Measurement, and ANSI/ESD S
