Katy Holdredge, senior staff engineer with the Energy and Industrial Automation group at UL Solutions, was appointed vice chair of the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx).

The IECEx Ex Management Committee (ExMC) unanimously agreed upon Holdredge for the appointment at their September 2023 meeting in Edinburgh, Scotland. The International Electrotechnical Commission (IEC) Conformity Assessment Board (CAB) approved her for the role during their Oct. 22, 2023, meeting. Holdredge will begin a three-year term as vice chair on Jan. 1, 2024.

Holdredge currently serves as the IECEx Ex Assessment Group (ExAG) Deputy Convenor, USNC/IECEx Vice Chair and an IECEx Lead Assessor. She has been an active contributor to the field of global conformity assessment as it relates to the development and operation of Ex conformity assessment schemes for more than 20 years.

The IECEx is a multilateral certification system based on International Standards prepared by the IEC, and the International Organization for Standardization (ISO). Representing 36 countries and 66 global IECEx certification bodies (ExCBs) in the Certified Equipment Scheme, its members use the principle of mutual recognition of test results to obtain certification or approval at national levels worldwide. Approximately 4,500 test reports are issued annually to facilitate trade for the oil and gas industry in accessing global markets.  The IECEx also offers the evaluation and certification of competencies of individuals working in or for hazardous locations as well as the evaluation and certification of service providers for equipment repair, inspection and maintenance, and other safety-related activities.

Holdredge has focused on strategy, policy and quality related to global Ex conformity assessment throughout her career. These contributions have led to her recognition as a recipient of the IEC 1906 Award and designation as a Distinguished Member of Technical Staff of UL Solutions’ William Henry Merrill Society.
