DEF STAN 00-35, later revised as DEF STAN 00-035, is a UK Ministry of Defence environmental standard used to define environmental conditions, test procedures and severities for defence materiel and military equipment.

The standard provides guidance for evaluating defence equipment against anticipated environmental conditions and supports the selection of suitable environmental test procedures and severities.

Yes. The numbering was revised from DEF STAN 00-35 to DEF STAN 00-035. The exact issue, part and procedure should always be confirmed before testing begins.

Programmes may include mechanical, climatic and chemical or biological exposures such as vibration, shock, temperature, humidity, sand, dust, corrosion and fluid contamination.

Yes. Mechanical assessments may include vibration, shock, drop, impact and acoustic environments depending on the applicable procedure and equipment requirement.

Yes. Environmental conditions may include temperature, humidity, pressure, altitude, wind-blown dust and wind-blown sand exposures.

Provide the applicable DEF STAN reference, equipment description, drawings, intended operating environment, mounting configuration, monitoring requirements and acceptance criteria.

Test severities should be selected based on the equipment’s intended storage, transportation and operational environments together with the applicable DEF STAN procedure.

Environmental qualification programmes are often reviewed alongside customer specifications and industry requirements where multiple test standards apply.(Suggestion based on common programme planning, not explicitly stated in the source document.)
