The standards development process is intended to be an open process where a variety of interests are engaged in developing timely, scientifically based consensus standards that fulfill UL Standards & Engagement's mission. This document is intended to assist participants in that endeavor.


The statements of principles contained within this Code of Ethics have been prepared to guide the conduct of participants in our Standards development activities to comply with the highest ethical and legal standards. This Code of Ethics applies to all participants in the UL Standards & Engagement standards development process, including Technical Committee (TC) members. It is essential that all participants in our Standards Development Process conform to these principles. These principles are not intended to supply specific guidance for every activity, but rather to provide guidelines for ethical behavior, which must be observed by all participants throughout the world. Where the Code of Ethics is specific, it should be followed to the letter. If certain situations are not expressly covered, participants are expected to consider the spirit of this Code of Ethics in determining the most appropriate course of action. UL Standards & Engagement takes violations of the Code of Ethics very seriously. Violations of this Code may result in an immediate termination of membership on a TC, sub-committee, working group, or task group, as applicable.


3.1 Participants shall act honestly and in good faith with a view to the best interest of our Standards Development Process. Although it is recognized that legitimate differences of opinion frequently exist on individual issues, all participants are expected to work in a constructive, respectful, and collaborative effort pursuant to resolving such differences.

3.2 Participants should give consideration to all points of view.

3.3 In all discussion, debate, and deliberation within the Standards Development Process, participants shall confine their comments to the merits and substance of the issues under review. Although participants may zealously advocate their views or positions, they shall refrain from debate and discussion that is disrespectful, threatening, or otherwise unprofessional in tone or which is personalized or offensive to other participants and damaging to the overall process of achieving consensus.

3.4 Participants shall take appropriate steps to ensure that any public statements, either written or oral, which are not official statements of UL Standards & Engagement, are properly portrayed as the opinion or position of that individual participant. Participants shall refrain from making statements that mislead the public.

3.5 TC Members and individuals serving on other consensus body committees or similar groups have a continuing obligation to provide UL Standards & Engagement with timely, accurate and complete information concerning their qualifications, organization affiliations and interest classification.

3.6 TC Members or individuals serving on other consensus body committees or similar groups who have been classified General Interest comprise a category of independent consultants and experts who are generally unallied with any particular business or commercial interest. On occasion, however, independent consultants in this category may be retained by a client to advocate on behalf of the client with regard to a specific issue or issues before the TC or committee. Accordingly, the consultant shall declare those interests to the TC or committee in a timely fashion and shall refrain from voting on any proposal relating to issue(s) in which the interests of the consultant's client are or may be potentially involved.

3.7 TC Members and individuals serving on other consensus body committees or similar groups frequently receive funding from their employers, organizations, or other sources for their participation in our Standards Development Process, and they have an affirmative and continuing obligation to declare those sources of funding to UL Standards & Engagement. Apart from those declared sources of funding, TC or committee members must not solicit or accept gifts, hospitality, or transfers of economic benefit, other than unsolicited gifts or other benefits of nominal value, i.e., USD $100.00 or less, from persons, groups, or organizations having dealings with their TC or committee, or under any circumstances in which the benefit would be or could appear to be bestowed or accepted for the purposes of influencing the members' activities within the Standards Development Process. This Section is not intended to prohibit authorized reimbursements by UL Standards & Engagement for travel and living expenses of TC or other committee members nor authorized honorariums paid by UL Standards & Engagement.

3.8 Participants shall treat all persons with respect and fairness and should not offer or appear to offer preferential treatment to any person or group.

3.9 Participants shall refrain from disseminating false or misleading information or from withholding information necessary to a full, fair, and complete consideration of the issues.

3.10 Participants shall not harass, threaten or coerce any TC or committee members in an effort to persuade or sway votes. This does not preclude professional, respectful communications that contain information and/or present perspectives intended to persuade other participants to lend their support or opposition to issues, proposals, etc.
