Specifications and standards

Over time Silmid have gained extensive knowledge of military and defense specifications and standards for armed forces all over the world, including the following;

  • NATO 
  • DOD


Specifications (often informally referred to as a specs) refers to an explicit set of requirements to be satisfied by a material, design, product, or service. If a material, product, or service fails to meet one or more of the applicable specifications, it may be referred to as being out of specification. 

A specification is a technical standard, a technical specification may be developed by various kinds of organisations both public and private. 


defense standard is a document that establishes uniform engineering and technical requirements for military-unique or substantially modified commercial processes, procedures, practices, and methods. 

There are different types of defense standards: interface standards, design criteria standards, manufacturing process standards, standard practices, and test method standards. 

United States defense standards, often called a military standard, "MIL-STD" or "MIL-SPEC", are used to help achieve standardisation objectives by the U.S. Department of Defense, the UK uses "DEF-STAN" to set similar standards across its military.

What is the importance of specifications and standards

Military equipment can be used in extreme environmental conditions, specs and standards have evolved from the need to ensure proper performance, maintainability and reparability (MRO) and logistical usefulness of military equipment. 

MRO and logistics were big drivers behind standardisation the need for greater interchangeability during times of conflict, during World War 2 allied forces were busy standardising and cataloguing. The U.S. AN- cataloguing system (Army-Navy) and the British Defence Standards (DEF-STAN) are great examples of this.


Silmid provide a range of re-pack services to military customers and suppliers. The ability to repack small volumes of materials with a fast turnaround provides a truly value added service. To ensure the optimum application of many materials, the pack size or pack format, can be changed to reduce waste, save time and improve accuracy.
