Editorial Policy

This policy describes how the calculators, reference pages and guides on Standard Clarity are produced, checked, and kept current.

Sources

We cite the relevant standards, publisher information and technical references where available. A catalog page establishes an edition or scope; it does not demonstrate that every table has been independently checked. Published approximations are identified as such, and official standards remain the property of their publishers.

When the full standard is unavailable, a public technical source may support a limited explanation or approximation. We do not treat that as verification of every requirement in the standard. The applicable edition and product-specific requirements must still be checked.

How calculations are produced and checked

• The standard's own formula is used wherever one exists, with its published constants.
• Software checks compare specified input cases, arithmetic, supported boundaries and error handling. They do not certify a product or validate every physical assumption.
• Where a standard presents its data as charts rather than a closed formula, any interpolation model used is identified and its limits are stated.
• The governing standard and clause are shown on each tool, so any figure can be traced back to its source.

How reference and explainer content is produced

Alongside the calculators, Standard Clarity publishes reference pages and explainers, such as the standards guides and the IP rating pages. They follow the same discipline as the tools:

• Claims should be tied to a specific source and scope. Unsupported accuracy guarantees or adjustment factors are corrected or removed when identified.
• Each page names and links the standard it explains, and separates what the standard actually specifies from the common misreadings of it.
• Comparisons between ratings or standards describe how the underlying tests differ, rather than presenting one rating as simply higher or better than another.

Accuracy and validity

Read each tool’s method and coverage before using its output. A result can be unavailable outside the stored data or solver domain. A numerical check, editorial update and independent technical review are different activities; an editorial date does not imply a named engineer has approved the model.

When standards disagree or do not map cleanly

For some questions, more than one published method or standards framework applies and they do not line up cleanly. PCB current-capacity methods are one example: IPC-2221C is actively revised while IPC currently lists IPC-2152 as No Longer Maintained. IP codes and NEMA enclosure Types are another: they cover overlapping but different characteristics, so any cross-reference must be attributed to a specific source and edition rather than treated as permission to relabel a product. We show those limits instead of silently collapsing different methods into one answer.

Corrections and updates

Accuracy comes before completeness. Standards are revised over time, and content is reviewed and updated to reflect meaningful changes. If you find an error in a calculation, a formula, or a reference value, please report it through the contact page. Corrections to the numbers are prioritized and made promptly.

Independence

Editorial decisions, including what a tool calculates, which method it uses, and what it reports, are made on technical grounds alone and are not influenced by any commercial relationship. Standard Clarity is independent and not affiliated with any standards or certification body. Standard names are used only to identify the documents the content is based on.

Independent technical reviewers are credited only after they have actually reviewed the stated scope and agreed to be named. Current software release notes describe the checks performed and any remaining limitations.
