JSS 0251 & JSG 0308 Documentation: Building DefenceReady Technical Literature
In the world of defence documentation, formatting isn’t just about making things look good — it’s about ensuring clarity, consistency, and compliance. If you’re an OEM, supplier for Defence Industry, working with the Indian Ministry of Defence, understanding JSS 0251 and JSG 0308 formats is a must, even if you don’t have to memorize every clause. At Code and Pixels, we specialize in creating high-quality technical literature that is fully aligned with these key standards. Formatting is important for maintaining clarity, consistency, and compliance in defense documentation, not just for making it look good. Even though you don't have to commit every clause to memory, knowing the JSS 0251 and JSG 0308 formats is essential if you work with the Indian Ministry of Defence as an OEM or supplier for the defense industry. Our specialty at Code and Pixels is producing excellent technical Documentation that completely complies with these important guidelines.

JSS 0251
JSS 0251 is a Joint Services Specification mandated by the Indian Ministry of Defence that defines how technical publications for electronic and electrical equipment should be structured and formatted. Instead of every OEM producing manuals in its own style — like consumer products — defence documentation must follow this unified, documented format so that operators, maintainers, and technicians can easily find and use the information.
JSS 0251 (JSS 0251-01:2015)
JSS 0251 is an official Indian Ministry of Defence standard for the preparation and production of technical manuals for electronic and electrical equipment supplied to the Indian Armed Forces (Army, Navy, and Air Force).
This standard ensures: •
A uniform and standardized format across all defence technical publications
•
Clear, structured documentation for operation, maintenance, and troubleshooting
•
Elimination of ambiguity through consistent layout, terminology, and content flow
•
Mandatory compliance for all OEMs supplying electronic/electrical systems to Defence, for both hard copy and soft copy manuals
JSS 0251 defines the complete structure, content sequencing, formatting rules, and inclusion of essential sections such as operational details, maintenance procedures, and spares information. Any electronic or electrical equipment delivered to Indian Defence must be supported with documentation compliant to JSS 0251.
JSG 0308 JSG 0308 is a Joint Service Guide focused specifically on Illustrated Parts Lists (IPLs) and User Handbooks (UHBs) for engineering equipment. It complements JSS 0251 by giving a clear, structured way to present parts, components, and user-centric instructions that engineers and maintainers will rely on in the field.

JSG 0308 (JSG 0308:2017 – Second Revision)
JSG 0308 is a Joint Service Guide issued by the Indian Ministry of Defence for preparing standardized technical documentation for engineering equipment. It primarily governs: •
Illustrated Parts Lists (IPL)
•
User Handbooks (UHB)
This standard ensures: •
Consistent documentation formats for easy identification of parts
•
Clear operational and maintenance instructions
•
Defined chapter structure and presentation rules for text, tables, drawings, and illustrations
•
Faster user understanding, reduced errors, and efficient spares ordering
JSG 0308 is used across the Army, Navy, and Air Force and is often implemented alongside JSS 0251, especially when documentation is integrated into Electronic Technical Manuals (IETMs).
How These Standards Improve Documentation Quality 1. Consistent Structure Across Documents Specific chapter layouts, headings, tables, and graphic placements are needed for both formats. Even under pressure, this consistency makes it easier for operators and maintainers to quickly locate the correct information. 2. Clear Parts Identification When ordering spare parts or fixing equipment, JSG 0308-compliant IPLs are made to enable users to accurately identify Part No., Nomenclature, Quantity, and related assembly details. 3. Standardized User Guidance In accordance with JSG 0308, user manuals provide lifecycle information, handling precautions, and operational procedures so that equipment can be used and maintained efficiently for the duration of its useful life.

4. Essential for Defence Projects In accordance with JSG 0308, user manuals provide lifecycle information, handling precautions, and operational procedures so that equipment can be used and maintained efficiently for the duration of its useful life. it’s often a contractual requirement in RFQ’s and PO’s.
What Documents Fall Under These Formats? Depending on your contract and equipment type, the documentation that must be prepared in these formats may include:
JSS 0251-oriented publications: •
Design Specifications
•
Technical Manuals
•
Procurement Drawings
•
Packaging Specifications
•
Spare Parts Lists
•
Carried Spares Lists
•
User Handbooks (if not in JSG 0308 format)

JSG 0308-oriented publications: •
Illustrated Spare Parts Lists (ISPL)
•
User Handbooks (UHB) designed for engineering equipment
The end-user specifications listed in your RFQ’s or PO’s will determine the formatting you select. For instance, while other manuals, such as Technical Manuals, are shaped by JSS 0251 requirements, ISPLs and UHBs may be specifically required to adhere to JSG 0308 Standard.
Why We Know These Standards Well We at Code and Pixels deal with documentation every day, that needs to adhere to stringent defense standards.
