1. Since the dawn of history of mankind, Standardisation has existed in some form or the other. Imagine, how difficult it would be, to have international trade/travel without standards of unit or measurement such as length, mass and time etc. The necessity of Standardisation was felt during the 2nd world war when the Allies could not get the war equipment of inter changeable nature. All these resulted in formation of International Standards Organisation (ISO) which has defined “Standardisation” as “The process of formulating and applying rules for an orderly approach to a specific activity for the benefit and with the cooperation of all concerned and in particular for the promotion of optimum overall economy, taking due account of functional conditions and safety requirements”.

2. From both logistics and economic considerations, lesser the variety of items purchased, stocked, transported and used by the Services, the better the war preparedness and fighting fitness. Hence “Defence Standardisation” is defined as “A means to provide the use of minimum number of parts to serve the maximum number of purposes consistent with economical manufacture, minimum whole life cost and the quality/reliability necessary to ensure maximum fighting effectiveness”.

3. Standardisation Directive The benefits of Standardisation were realized in the Ministry of Defence as early as 1959 when Standardisation Committee was set up under SA to RM. Based on their recommendations, Directorate of Standardisation was set up in the year 1962. Experience gained over the subsequent years resulted in the issue of ‘Standardisation Directive’ by the Government in Oct 1977 which laid the foundation of Standardisation activities in Defence on a sound footing. Basic aims of Standardisation therefore are as follows.

  1. Variety reduction of existing inventory.
  2. Effective Means of Entry Control.
  3. Laying down procedures, methodology and guidelines that result in saving of Time, Money and Resources.

The Chairman of Standardisation Sub Committees and Technical Panels may constitute Working Groups within the Sub-Committee/Technical Panels for progressing specific standardisation tasks which need expert and detailed study. Such Working Groups will be dissolved on completion of the assigned task.
  • Specialist Technical Panels.To help the designers of equipment, an Equipment Technical Panel has been created known as ‘Specialised Technical Panel for Human Factor for Designers of Equipment’.

Defence Equipment Codification Committee (DECC)

    5. To formulate rules and procedures for Joint Services Cataloguing.

Functions Related to Entry Control and Variety Reduction

  • Two important activities of the Directorate of Standardisation as mentioned in policy Directive are Entry Control and Variety Reduction. To achieve “Entry Control” the Directorate prepares Joint Services Catalogues based on NATO Codification system. Catalogues are being published group-class wise and circulated to all concerned AsHSP and the Standardisation Sub Committees. When a new Store/Item is introduced into the Services these Catalogues are checked through Computer Media to prevent duplication thereby ensuring “Entry Control”.
  • Entry Control.‘Entry Control’ through Standardisation is planned and implemented for preventing variety of items from entering the supply system. When one service wishes to introduce any item, it shall first refer to the preferred Ranges or Joint Services Specifications issued on similar items. If item being introduced is dissimilar to that listed in a preferred Range or Joint Services Specification, it shall do so only after referring to the Directorate of Standardisation. Introduction of the items to the service are to be selected from the preferred Ranges of the items so that proliferation of the items is checked. Further, in case any item is available in any of the service; the utility of the same is to be checked by the service which wishes to introduce the item. For effective Entry Control, it is desirable to codify the entire current Defence inventory.
  • Variety Reduction. To achieve ‘Variety Reduction’, the following types of Standardisation documents are prepared:-
    1. Joint Services Preferred Range (JSPR). JSPR is a list of stores/materials/ size and grades to cover the production preferred numbers, also called Renard Series. In the Defence industrial design, it forms the guidelines for choosing exact dimensions/values which govern the defence production. In our context it specifies the sizes/grades/capacities required for the users to cover their full requirement though many more grades and sizes may be available commercially.
    2. The list of store belonging to a particular group/class are examined by the Sub-Committees and documents like Joint Services Preferred Range (JSPR) and Joint Services Rationalised List (JSRL) are prepared to ensure “Variety Reduction”. Further, Joint Services Specification (JSS) is prepared for particular store or Indian Standards (IS) is adopted based on the JSRL already prepared in that particular group class of stores/items.


  • The Directorate website is managed by Data Network Complex (DNC). The website facilitates online availability in-house developed standards. The website contains following documents/publications that can be accessed by a registered defence user:-
    1. All defence standards like JSSs, JSPRs, JSRLs, JSGs, ANs.
    2. Manuals of Standardisation and Codification.
    3. Approximately 21000 Indian Standards from BIS that can be directly printed.

4. Selected Naval Standards which are hosted by the IHQ MoD (Navy) and a separate password is allotted for the purpose with the approval of IHQ MoD (Navy)/PDEE.

5. Selected Naval Standards which are hosted by the IHQ MoD (Navy) and a separate password is allotted for the purpose with the approval of IHQ MoD (Navy)/PDNA.
