Status definitions
Every lab and calculator carries two separate labels: whether you can open it, and how much checking it has actually had. We keep them separate on purpose — a tool being live says nothing about whether an engineer has reviewed its content.
Availability

- Availability: AVAILABLE
- Published and open to everyone, with or without an account.
- Availability: PREVIEW

Validation
How much review has this release had? This label is derived only from evidence recorded in our governance register. Where no evidence exists, we say so rather than implying review.

- A subject-matter expert on the build team has reviewed this release against its referenced sources.
- Validation: SME REVIEW IN PROGRESS
- A subject-matter expert review of this release has started but is not complete.
- Validation: AUTOMATED CHECKS ONLY
- Automated load, runtime, and accessibility checks passed on the recorded date. No subject-matter expert has reviewed the engineering content.
- Validation: VALIDATION DETAILS PENDING
- No validation evidence has been recorded in the governance register for this release yet.
- Validation: NOT APPLICABLE

Standards basis
What is the relationship to published codes and standards?
- Standards basis: EDITION VERIFIED
- Inputs and results were checked against the stated code or standard edition.
- Standards basis: STANDARDS-AWARE
- Follows the methodology of the referenced standards without certifying compliance.
- Standards basis: MAPPING INCOMPLETE
- References are partially mapped. Verify against your applicable edition.
- Standards basis: CONCEPTUAL ONLY

- Standards basis: NOT APPLICABLE
- No code or standard basis applies to this item.
WHAT WE DO NOT CLAIM
Phase Academy is not affiliated with NFPA, IEEE, NETA, or any standards organization, and nothing here is certified, approved, or endorsed by them. Tools that follow a standard's methodology are described as aligned with or referencing that standard — never as compliant. Results are educational and must be verified against the applicable code edition by a licensed professional. See our Terms.
