This Standard specifies the processing and quality assurance requirements for brazing processes for space flight applications. Brazing is understood as the joining and sealing of materials by means of a solidification of a liquid filler metal.

The term brazing in this standard is used as equivalent to soldering, in cases that the filler materials have liquidus temperatures below 450 °C.

Brazing and soldering are allied processes to welding and this standard is supplementing the standard for welding ECSS-Q-ST-70-39.

This standard does not cover requirements for:

- Joining processes by adhesive bonding (ECSS-Q-ST-70-16),

- Soldering for electronic assembly purposes (ECSS-Q-ST-70-61),

- Soldering used in hybrid manufacturing (ESCC 2566000).

The standard covers but is not limited to the following brazing processes:

- Torch brazing,

- Furnace brazing,

- Dip Brazing and Salt-bath brazing,

- Induction Brazing.

This Standard does not detail the brazing definition phase and brazing pre-verification phase, including the derivation of design allowables.

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