Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose. Standards provide organizations with the shared vision, understanding, procedures, and vocabulary needed to meet the expectations of their stakeholders. Because …

The Satellite has a large number of electronic systems and subsystems which are critical to the functioning and its mission. The spacecraft is divided into two sections: the platform or bus and the payload. The platform consists of the five basic subsystems that support the payload: the structural subsystem, the …
Read More »Defense standards evolved from the need to ensure proper performance, maintainability and reparability (ease of MRO), and logistical usefulness of military equipment. The latter two goals (MRO and logistics) favor certain general concepts, such as interchangeability, standardization (of equipment and processes, in general), cataloging, communications, and training (to teach people …

MIL-STD 810 is a Department of Defense Test Method Standard for environmental engineering considerations and laboratory tests. It is the most popular Military specification used to conduct environmental testing of military products. Given the fact that these products may be exposed to harsh or even extreme conditions, their reliability under …

Construction and demolition (C&D) materials are generated when new building and civil-engineering structures are built and when existing buildings and civil-engineering structures are renovated or demolished (including deconstruction activities). Civil-engineering structures include public works projects, such as streets and highways, bridges, utility plants, piers, and dams. C&D materials often …
