William Henry Merrill Society
Corporate Fellow

Bent Winther’s contributions and accomplishments over the span of his 36-year career with Demko and UL encompass his technical contributions to electrical safety standardization, his vision and creativity in shaping Pan-European and International Product Safety Certification Programs, and his leadership in his professional community.

Mr. Winther has been a visionary for electrical safety, and has been a prolific author in drafting standards and documents on behalf of various committees. He has been tireless in his persistence throughout the tedium of bringing standards to fruition through national and international standards development processes. He has readily shared his knowledge through presentations to staff, manufacturers and authorities by presenting and explaining new developments in standards and programs.

Mr. Winther earned a reputation for his ability to take on and resolve a wide range of challenges. Between 1978 and 1984, during which he also served as a member of the Demko Board, Demko experienced a period of considerable challenge as a consequence of a move from the use of Danish National Standards to the use of European Norms. The Board gave Mr. Winther the task of investigating the situation and developing recommendations for their consideration. His solution led to approval for construction of a new 5,000 square meter laboratory, addition of 34 new staff members, and purchase of $700,000 of new test equipment. Successful implementation of these changes vastly improved the overall quality and timeliness of services performed by Demko’s engineers.

Later, when the Danish government decided to put Demko into the private sector, Mr. Winther served as an indispensable advisor leading to the successful transfer of Demko to UL.

When other test houses challenged the method used by Demko for conducting testing of motor-compressors using a substitute cooling system, Mr. Winther convinced the IECEE Committee of Testing Laboratories (CTL) that the method was sound. Since then, the method has been widely adopted. For more than 20 years, Mr. Winther continuously worked on improvements of the Standard to cover changing technology in the construction of motor compressors, their increased use of electronic controls and protection, and the use of new refrigerants.

Mr. Winther has always had an active interest in the well being of his fellow employees. In addition to serving as a member of the Demko Board, he served a position of trust as Chairman Spokesman for the Demko Graduated Engineers Association. During this period, he served as the link to the upper management of Demko in all matters in relation to reorganization of Demko and all hiring of graduate engineers. This position also gave Mr. Winther the responsibility to negotiate work conditions and salary and other conditions for the engineers. He received much recognition for the many years he served in this capacity, from all parties involved, both inside and outside of Demko.

Mr. Winther served as a mentor and teacher, freely sharing his knowledge and providing leadership through technical advice and direction to others both at UL and elsewhere.

Mr. Winther has always placed his first priority on UL’s Mission of Public Safety and the performance of the various European and international interpretation committees and agreement schemes. His effectiveness has been greatly aided by his attention to maintaining strong, positive relationships, both internal and external to Underwriters Laboratories Inc.

Mr. Winther’s work has been of utmost value in the achievement of good standards, good working schemes and good service. This has been particularly evident by the addition of 14 new CBTLs to UL Demko, largely through his leadership and personal efforts.

Class of 2007

Primary Designated Engineer

Over the course of his 30-year career with UL, Kerry Bell has been recognized as a leader in the development and implementation of Codes and Standards for fire sprinklers and sprinkler system equipment. He is well known and highly respected by the Sprinkler Industry, the Code Development Community and the Regulatory Community for his technical expertise in fire suppression systems.

Mr. Bell has actively applied his fire protection engineering education and experience in evaluating sprinklers and related equipment to advance the state-of-the-art in active fire suppression. He has made innumerable contributions through leadership in the application of improved and new technology to develop UL Safety Standards for fire sprinklers and related fire sprinkler system equipment. Of particular note are the contributions he made to the development and implementation of requirements for plastic sprinkler piping.

Mr. Bell has readily shared his knowledge throughout his career, through active participation and leadership in technical and professional organizations. He has been recognized by UL, as well as by other organizations, in various ways for his accomplishments and contributions.

Mr. Bell has served as an active member of more than two-dozen national and international technical committees involved with the development of standards and codes for sprinklers and related sprinkler system equipment. His standing in the Codes and Standards Community was underscored by his appointment to serve as a member of the prestigious National Fire Protection Association (NFPA) Standards Council. The 13 members of the NFPA Standards Council serve as the final arbiter for the issuance of the internationally recognized NFPA Codes and Standards. This appointment reflects NFPA’s respect for Mr. Bell’s important, effective, sound and unbiased contributions, over many years, to the development of NFPA Codes.

Mr. Bell has been called upon on numerous occasions to take responsibility for addressing some of the most challenging issues and opportunities facing UL. When the long-term performance of polymer sprinkler seals came into question, Mr. Bell assumed leadership for developing an understanding of the fundamental performance and failure characteristics of the materials, and worked closely with Industry, Government and Regulatory Authorities to bring about successful resolution of the situation that might otherwise have become extremely contentious.

Mr. Bell also served in a lead role in developing design criteria for UL’s David Gratz Fire Test Center at Northbrook, Illinois. This facility has served, through nearly a decade of use, to help position UL as the world’s premier fire suppression testing organization.

Mr. Bell has served as a mentor and teacher, freely sharing his knowledge and providing leadership through technical advice and direction to others both at UL and elsewhere. He has always focused on UL’s Mission of Public Safety as his first priority in all of his activities and in all of his relationships to Underwriters Laboratories Inc.

Business Development Director
Underwriters Laboratories Inc.

Pravin Gandhi is well known in the North American and International Fire Protection Community as a leading fire researcher and, perhaps more significantly, for translating the product of fire research into economically useful applications in testing and certification of materials, products and systems.

As an academic, Dr. Gandhi is an accomplished fire researcher across a wide array of technologies. He has been an outstanding ambassador for UL, as evidenced by his presentations of his investigations at U.S. and international fire safety conferences. He also demonstrates a practical business sense by his leadership in the translation of fire research into the application of new technologies in UL’s fire protection testing and certification activities.

Equally compelling is the impact that the implementation of these new technologies has had on the transformation of the work of UL’s fire protection engineers. Prior to introduction of these various technologies in UL’s work, most fire testing yielded little more than a “pass” or “fail” result. With the introduction of these technologies, it became possible to develop an understanding and explanation as to the way in which materials and systems perform under fire conditions. A case in point is the fire modeling services UL offers to clients using advanced FDS (fire dynamics simulator) programming code developed by the National Institute of Standards and Technology (NIST). With this, UL delivers more value to its clients for each dollar spent on testing. UL is now able to provide manufacturers with information on which they can design improvements in materials, products and systems.

Thanks in large part to Dr. Gandhi, UL is able to study a range of variables through analytical modeling techniques, permitting a wide range of features and conditions to be evaluated through fewer tests. These new technologies have enhanced UL’s reputation, affecting an increase in the demand for UL’s unique fire capabilities. These new fire technologies now account for ten percent or more of UL’s fire protection services revenues.

Also significant, and perhaps the strongest endorsement of Dr. Gandhi’s being chosen as a Corporate Fellow is the manner in which he freely shares his knowledge and enthusiasm with others. He has consistently gone out of his way to act as teacher and mentor to enable others to develop new capabilities and understand and apply new technologies. He willingly shares the limelight, and routinely works to help others achieve success.

It is apparent that he takes great satisfaction in seeing others succeed. Although working with and through others in this way greatly multiplies what UL has been able to achieve as a consequence of Dr. Gandhi’s knowledge and capabilities, it also means that his contributions often may not be as publicly apparent and lauded as they might be.
