FIELD: tests of polymer materials contained in structures of space equipment in outer space and on ground.
SUBSTANCE: proposed method includes placing the material specimens on surface of spacecraft for exposure during required period of time. Then, specimens (kept in container) are placed in transport container which is sealed up in outer space and is returned to ground. Properties of material are estimated in laboratory. Hermetic transport container is placed in vacuum chamber filled with inert medium; container is opened in this chamber and specimens are withdrawn from it. Each specimen is placed in separate hermetic case and chamber is evacuated, after which their properties are studied in vacuum chamber.
EFFECT: reduction of post-exposure ground effect on specimens tested in space.
