Abstract
Conducted Energy Weapons (CEWs), such as those manufactured by TASER International Inc., are seeing increased use by law enforcement agencies as a less lethal force option; but, at the same time, these weapons are also seeing an increased level of concern in terms of their safety of use. In order to enable consistent evaluation of CEW performance, a systematic protocol for testing the electrical output of such weapons is required. In this paper, we propose a test specification for CEWs, designed to calculate the key performance and electrical safety parameters. The weapon is fired into a specified load, and current or voltage data are acquired, from which a set of electrical parameters are calculated and recorded. The protocol is based on experience of testing 6000 CEWs in the labs affiliated with the authors. This test protocol is designed to enable systematic testing, evaluation and research on CEW’s, including identification of weapons which are out of specification, determination of changes in weapon characteristics over time, and evaluation of weapons post-incident. Based on the proposed test protocol, we evaluate and report on electrical output produced by 208 X26TM and128 M26TM TASER? weapons. Results are shown in terms of proposed summary parameters and in terms of manufacturer’s performance specifications.

The paper is structured as follows: First, we develop a standard for testing of CEWs, and based on the proposed test protocol; we evaluate and report on electrical output from 208 X26TM and 128 M26TM TASER weapons
Summary
Conducted Energy Weapons (CEWs) are increasingly used by police in many countries as a less-lethal force option. The most widely used CEWs are the M26TM and X26TM models from TASER International Inc. The weapon sends a pulsatile electrical current into the subject, designed to be sufficiently rapid and with enough energy to cause muscular incapacitation [1]. This incapacitation is intended to give an arresting officer time to gain control over the subject. Other research has analyzed reports from police, coroners, medical case reports and computer models of current flow in the body [9,10,11,12]
