The following table lists a few specific HES standards to illustrate the system's content and the types of technical requirements it governs. Note that these are provided for informational purposes only; the actual PDFs are not publicly distributed.
The Honda Engineering Standard (HES) is the ultimate blueprint for quality within the Honda supply chain. From the chemical restrictions of HES D 2008 to the coating validations of HES D 6501, achieving compliance requires precise adherence to these documents. Ensure your engineering team utilizes official, current PDFs directly sourced from Honda portals to safeguard your manufacturing pipeline and maintain your standing as a trusted automotive partner.
Defines exactly which vehicular systems or component classes the document covers.
The Honda Engineering Standard (HES) is a proprietary set of technical specifications, testing procedures, and material requirements established by Honda Motor Co., Ltd. It governs the design, testing, quality assurance, and manufacturing of every component used in Honda vehicles, motorcycles, and power equipment. honda engineering standard pdf
Honda continuously updates its standards to reflect new technologies and regulatory shifts. Always check the revision suffix (e.g., Rev A, Rev B) on the PDF cover page against your specific engineering drawing to ensure you are testing against the correct historical or modern iteration.
: Specifies fire-retardant properties required for cabin textiles, foams, and plastics. Critical Testing Protocols Specified in HES
Automotive standards are revised frequently. Using an obsolete version of a standard can result in failed part submissions or costly production recalls. The following table lists a few specific HES
Mechanical components, machining tolerances, and standardized fasteners.
Ensures a Honda vehicle built in Ohio meets identical quality metrics as one built in Suzuka or Swindon.
| Standard Code | Category & Title | Key Technical Requirement | | :--- | :--- | :--- | | | Design / General Geometric Tolerances | Defines general tolerance limits for linear and angular dimensions when no tolerance is noted on the drawing | | HES B011-03 | Parts / Projection Weld Nuts | Specifies dimensions, material (e.g., Class 8 steel), and quality control (100% optical sorting for robot welding) for square weld nuts (e.g., M4 to M12 sizes) | | HES C 206-17 | Materials / Interior Flammability | Establishes burn rate limits for interior materials; materials must be non-flammable or self-extinguishing, with a burning rate below specified values | | HES D6501-06 | Testing / Coating Methods | Describes general test methods for coatings, including the widely used "pencil scratch hardness test" to evaluate coating durability | | HES D6003-12 | Testing / Material Flammability | Outlines the specific test procedure for measuring burn rates on interior materials, including lab conditions (21°C / 50% RH), test piece dimensions (100mm x 356mm), and apparatus specifications | | HES D0020 | Testing / Rubber Tolerances | Governs the fundamental dimensional tolerances for machined rubber parts (seals, grommets, etc.), specifying class-based allowable deviations (Class 1 and Class 2) | | HES H 037 | Drawing / Title Block Format | Dictates the exact format, data fields, and revision protocol for all Honda engineering drawing title blocks | From the chemical restrictions of HES D 2008
: Standards are frequently revised. Honda uses secure, closed portals to ensure suppliers always access the most current revision.
The HES documentation is structured into several distinct groups, each targeting a specific phase of the engineering and production lifecycle:
