Guidelines for Developing a Proposal

Submitting a proposal that addresses the following criteria facilitates acceptance and processing of your request.

1. The Proposal Request is fully developed and complete.

  • Include a technical Rationale Statement for the proposal. A good rationale includes the reasons for (the "Why," such as a statement of the problem) and the objective of the proposed change.

  • Provide specific wording for the proposal and recommended placement within the standard. Take into account all areas of the standard that are impacted by the proposal.

  • Show entire paragraph(s) with proposed new or additional text as underlined. Show text to be deleted with strikethrough.

 

2.  The language used in the Proposal Request meets the following objectives:

  • The proposal is written to address the safety concern in question.

  • The proposal is written so that it can be interpreted/applied consistently.

  • The proposal uses clear and concise language.

  • The proposal avoids language dealing directly with conformity assessment considerations (effective dates, certification issues, Listing and Recognition references).

 

3. The proposal does not infringe on the copyrights of other organizations.

  • When proposals include copyrighted material from other organizations, permission to reproduce the material will likely be required. Seeking that permission is typically the responsibility of the proposal submitter.  However, when the proposal includes  material copyrighted by an international standards body such as IEC, ISO, CEN or CENELEC the permission is obtained by UL. Please contact the UL Project Manager if guidance is needed.

 

4. A proposal to add or revise a test requirement includes the following elements:

  • Specific pass/fail criteria.

  • A well-defined test method.

  • Stated absolute limits or tolerances on dimensions or specifications that are consistent with existing requirements of the standard.

  • Repeatability and reproducibility of the test, if applicable.  (Repeatability refers to the closeness of the results of successive tests of the same sample, conducted using the same test procedure, the same tester, the same measurement instruments, under the same conditions, at the same location. Reproducibility refers to the closeness of the results where the same (type) sample is tested using the same test procedure, the same (type) measurement instruments, under the same conditions, but conducted by different testers, at different locations.)

 

This checklist does not address all issues or circumstances that might arise when preparing your Proposal Request. Refer to the UL Style Manual for additional guidance in preparing proposals.
