14、foreword is not part of ESD Association Standard Test Method ANSI/ESD STM97.2-2016) FOREWORD This standard test method1 is intended to provide test methods for measuring the voltage on a person in combination with footwear and floor materials as a system. This standard test method covers all floor m
15、aterials used to control Electrostatic Discharge (ESD) including floor mats, floor coverings, coatings, paints and floor finishes together with footwear. This standard test method is limited to defining procedures for measuring the voltage accumulation on personnel in combination with footwear and f
16、loor materials. This test method provides data that is relevant in the users specific environment, application and controlled laboratory conditions. A common source of electrostatic voltage on a person in a work environment is when a foot separates from the floor while walking. The effect of this ge
17、neration and accumulation of electrostatic charge can be minimized with appropriate selection of the footwear/floor system. To effectively control voltage on personnel, floor materials must be used in conjunction with static control footwear. A footwear/flooring system that is conductive enough to d
18、ischarge a person also may pose a safety hazard. The work performed with these systems often entails the use of tools and test instruments that operate at voltages high enough to cause electrical shock. The presence of a footwear/flooring system tested using the methods described in this document wi
19、ll not guarantee personnel safety. This document was originally designated ESD STM97.2-1999 and approved on February 7, 1999. ANSI/ESD STM97.2-2006 was a reaffirmation, re-designation of ESD STM97.2-1999 and was approved on February 26, 2006. ANSI/ESD STM97.2-2016 is a revision of ANSI/ESD STM97.2-2

Summarize test data in the same table by reporting minimum, maximum, and mean of the absolute values obtained. 5.3 Test Procedures
27、 Installed or Applied Material Testing 5.3.1 Test Procedures for Voltage Measurements for Installed or Applied Material Perform five tests per floor material or a minimum of five tests for every 460 square meters (5,000 square feet) of floor material, whichever is greater. Record the three highest r
28、eadings for each test. A minimum of three of the five tests should be conducted in those areas that are subject to wear, have evidence of chemical or water spillage, or are visibly dirty. Test for voltage on a person in accordance with Section 5.2.3. See Annex B3 for sample test records. 5.3.2 Repor
29、ting of Test Results Report test parameters using the sample table in Annex B1. Report temperature and relative humidity, date of testing, type and identity of footwear, composition of shoe sole, identity of floor, name of test subject and test equipment used. Select the three highest readings for e

Summarize test data in the same table by reporting minimum, maximum, and mean of the absolute values obtained. Include a diagram showing approximate test locations and ground connect
31、ions used. ANSI/ESD STM97.2-2016 7 6.0 OTHER CONSIDERATIONS 6.1 The footwear/flooring system should be monitored to assure that proper maintenance procedures are being followed. 6.2 The data obtained under this standard should be analyzed by the end user in a manner consistent with the footwear/floo
32、ring system specifications for the materials being tested. 6.3 For further selection considerations, refer to the ESD Handbook (ESD TR20.20). 6.4 Complete characterization of the footwear/floor system should include the measurement of the resistance of the floor (ANSI/ESD STM7.1), resistance charact
33、erization of the footwear (ANSI/ESD STM9.1), and the resistance of the Footwear/Flooring System measured using ANSI/ESD STM97.1. Perform all tests at the following environmental conditions: 12% 3% RH and 23C 3C. ANSI/ESD STM97.2-2016 8 (This annex is not part of ESD Association Standard Test Method
34、ANSI/ESD STM97.2-2016) ANNEX A (INFORMATIVE) - ALTERNATE METHODS OF WALKING There are many ways one could choose to walk. The walking pattern described here simulates forward, backward and crossover movements typical of workers in a number of disciplines. However, other methods of walking are accept
35、able assuming that they simulate user actual patterns. For example, a simple box step can be used as in AATCC-134 or a longer forward and backward step pattern on a 2 foot x 8 foot pallet as described in the Bellcore work. The user of this test method should choose a step pattern typical of the majo
36、rity of the workers within your organization.
