ECSS-Q-ST-70-57C: Dry heat bioburden reduction for flight hardware (30 August 2013)


This standard defines procedures for the reduction of microbiological contamination of flight hardware using heat.

The procedures described in this standard cover:

  • Reduction of microbiological contamination on exposed surfaces, mated surfaces and encapsulated in materials.
  • Reduction of microbiological contamination in dry, ambient and uncontrolled humidity environments.

This standard also sets requirements for the conditioning of the flight hardware, bioburden reduction cycle development, and equipment to be used for applying a bioburden reduction procedure.

This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.
