| Best for | Using construction codes without treating classification as a machine setting, material assignment, supplier translation, or performance guarantee | Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence |
| 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. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. |

| 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. | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. |
