This policy explains how EnginesDIY prepares and maintains product pages and educational content.
Accuracy before publication
Editors compare model names, options, images and published specifications with the available product record. A product claim must be traceable to the current catalog data, manufacturer or supplier documentation, or a clearly identified authoritative source.
Use of external sources
Primary and authoritative sources are preferred for general engineering, aviation, energy and occupational-safety explanations. NASA, FAA, DOE, OSHA and NIOSH may be cited when their material directly supports the statement. Citations are contextual and do not represent product endorsement.
Commerce and independence
EnginesDIY is a retailer. Product pages may support a purchase decision, but editorial explanations must not invent testing, certifications, sales figures, reviews or expert credentials. Manufacturer brands are used only when they can be verified from existing product information.
Dates, updates and authorship
Articles display their original publication date and a modification date when substantively updated. The EnginesDIY Editorial Team author page describes the team function without assigning unsupported professional credentials.
Corrections
Material errors are investigated and corrected promptly. The process and reporting route are defined in the Fact-Checking and Corrections Policy.
