JSS 0251 AND JSG 0308 Documentation Formats

What is JSG 0308: 2017 how is different from JSS 0251-01: 2015?

Both JSG 0308: 2017 and JSS 0251-01: 2015 standards which are defined by sub committees of the Defence Authorities.

They aim to have standard for every OEM to follow the same document structure which will enable user to understand the equipment, Handling procedures and identify items (Parts List) correctly, ensure all the required data is furnished in a specific format required.

Both JSG 0308: 2017 and JSS 0251-01: 2015 standards provide the formats of the contents to be provided and defines the structure of the content to be provided in the documents.

For Example, it is defined that a specific document should have the specific chapters with the defined topics to be covered in that chapter along with the formats of the content to be placed (Imaged, Drawings, Tables, Text etc…) for the preparation and production of technical publications of the equipment required to be supplied by OEMs or Manufacturers.

Which documents can be prepared in JSG 0308: 2017 and JSS 0251-01: 2015 standards?

The documents will be prepare based on the End User requirements. The standard requirement to be specified by your End Client in your RFQ / PO, to which defence organisation you are going to submit the documents.

The JSG 0308: 2017 (Second Revision) is the Joint service Guide on Illustrated Part List (IPL) and User Hand Book (UHB) for Engineering Equipment.

The JSS 0251-01: 2015 (Revision No. 2) is the Joint Services Specification on procedure for preparation and production of Technical Publications for Electronic and Electrical Equipment.

As mentioned in JSS 0251-01: 2015 (Revision No. 2) the Technical Publications normally to be supplied by Design Authority/Manufacturer are:

• Design Specification
• User Handbook (UHB)

Design Specification:

It describes the technical characteristics of the equipment as a whole and those of the Assemblies/Sub Assemblies which have to be provided as spares. It prescribes the acceptable limits of performance based on the measured performance of the Models B/C and early production models. It includes specific tests to be carried out and environmental requirements. In case the specification for Assembly and Sub Assembly or their test procedure cannot be given in the Design Specification for the main equipment, this will then be supplied by Design Agency (DA) as and when required or when these Assemblies and Sub Assemblies are ordered separately as spares.

User Handbook:

This book accompanies the equipment at all times. It contains all the information that would be required by the operator to understand the functioning of the equipment, to operate it, carry out routine maintenance and checks and simple fault diagnosis and rectification.

It shall also include identification of mechanical/electrical components of all electrical and mechanical assemblies by means of blowups, photographs, isometric views or line diagrams, taking into consideration the cost effectiveness.

Procurement Drawings:

The procurement drawings consist of the minimum number necessary to specify what is required as a finished product (including accessories for various roles) and are supported by written specification where necessary. The drawings should contain sufficient information, for the purpose of procurement, acceptance inspection, identification and allotment of Cat No. to the equipment, accessories and separately demandable components.

Packaging Specification:

This specification gives the data relating to the packaging requirements of the equipment for long time storage in addition to the protection against transportation hazards.

List of Components:

The list should contain all separately demandable components with adequate data for the purpose of identification and allotment of Defence stores catalogue numbers to the components and to initiate Qualification Approval activities.

List of Carried Spares:

It contains recommended list of essential spares which are required to be issued along with each equipment to the user.

1. For Naval equipment only the list of carried spares will be in two parts:Onboard spares.
   • Onboard spares.
   • Installation spares.

Engineering Support Package:

The Design Authority is required to recommend a list of spares for two years maintenance and one overhauling of 10 equipment based on their knowledge and experience of the design and development of the equipment.

List of Accessories:

This contains list of accessories and ancillary stores which are required for installation/operation of an equipment or system in the desired role.

List of Special Tools, Test Equipments, Jigs and Gauges:

It contains list of tools, test equipments, jigs and gauges peculiar to the equipment which are required for alignment, repair and maintenance of the equipment but are not normally available in a workshop.

What is JSS 0251?

JSS 0251 is an India Ministry of Defence documentation standard for writing standard and precise technical guides and user manuals for deployed systems, subsystems, and equipment. The standard provides complete guidelines on structure, format, and terminologies.

JSS 0251 Documentation Services

We at Code and Pixels provide extensive documentation services according to JSS 0251 to ensure all the outputs meet original equipment manufacturers (OEMs), defense production units, and DRDO lab requirements. We are capable of:

• designing user documentation that assists technicians and operators in comprehending complicated systems
• Preparation of technical specification documents for electronic, mechanical, and software subsystems
• Documentation delivery and format to JSS 0251 and JSG standards
• Legacy document conversion to current formats of comply with the defense requirements
• Management coordination with the subject matter experts (SMEs) to check accuracy, performance specifications, and procedural clarity

What is JSS 0251

JSS 0251 is a defence documentation standard. To make it simpler, whenever we buy some household item, be it a fridge or AC, we get a user manual. If you look closely, each company follows their documentation structure or pattern and content flow. There will not be any similarities in formatting or layout. Every OEM has their separate documentation teams and they design in their way.

Even the size and dimensions of the document may be different.

Similarly whenever a simple system or complex system is delivered to defence users i.e. Army, navy or air force, along with the original equipment OEMs also has to supply Manuals.

But, in this Defence suppliers case, the defence wants all the OEMs to follow similar standards which are defined by them. They want every OEM to follow the document structure the same way.

These guidelines are drafted in JSS 0251-01: 2015 standards book. Every OEM has to follow the same guideline while delivering Softcopies and also Hard copies.

Normally, all these manuals are also copied in DVD and delivered along with hard copies. In the next steps, these all documents are converted to IETMs for very fast navigation. Referring to multiple PDFs might take some time, hence IETMs are developed as per defence standards JSG 0852: 2001

This specification talks about the procedure for the preparation and production of technical publications for electronic and electrical equipment.

These standards are drafted by the Directorate of standardization, department of Defence Production, Ministry of Defence.

JSS 0251 describes the format and procedure for the preparation and production of technical publications for electronics and electrical equipment required to be supplied by OEMs or manufacturers.

Along with equipment or subsystem, few technical publications are normally submitted by OEM to defence lab, or end-user i.e. army, navy or air force.
