| Best for | Using construction codes without treating classification as a machine setting, material assignment, supplier translation, or performance guarantee | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Coordinating an independent sewing-pattern test |
| Know before using | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. | The reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric. | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. |

| What the source establishes | The guide cites the official DLA cancellation record for FED-STD-751A and the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025). It records ISO 4915's July 2026 systematic review and keeps classification, ambiguous-code recovery, translation, complete process definition, physical verification, and performance evidence separate. | Rechecked July 27, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred. | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. |
