Feedback is strongly preferred within the digital specification development tool Jama Connect to allow more efficient compilation and response to comments. Please email feedback@jip33.org for access to the tool including details of the specification you would like to comment on.

Operator staff should contact the SC representative to feed their comments back through their SME.
If returning comments via the digital tool is not possible, please download the document and mark up your comments. Submit the marked up file to feedback@jip33.org

Keep in touch with what’s happening on JIP33 by signing up to our Mailing List. You’ll get automatic notifications when new draft specifications are published for public and/or maintenance review and comment. Each specification has a four-week review period and we’d love to receive your input.

Specifications in development: Drafts will be available here for public review as they are ready.
