Abstract

?medição de vazamento excessivo de um objeto de teste incompressível em uma câmara de película?, por tratar-se a presente invenção de um método para a medição de vazamento excessivo de um objeto de teste pelo menos parcialmente incompressível (18) em uma câmara de película (12), que compreende pelo menos uma região de parede flexível e é conectada, de maneira a permitir a condução de gás, a um sensor de pressão (30), a uma bomba de vácuo (26) e, por meio de uma válvula de calibragem (34), a uma câmara de calibragem (36) delimitando um volume de calibragem (37), sendo que o referido método compreende as seguintes etapas: evacuar a câmara de película (12); medir a curva de pressão dentro da câmara de película (12), depois de a evacuação ser concluída; conectar, de maneira a permitir a condução de gás, o volume de calibragem (37) ao volume interno da câmara de película (12) durante a medição da pressão, sendo que a pressão é medida antes de a conexão condutora de gás ser estabelecida, e com a conexão condutora de gás estabelecida, à câmara de película (12), e a pressão na câmara de calibragem (36) antes da conexão com a câmara de película (12) é maior ou menor que a pressão na câmara de película (12), caracterizado pelo fato de a diferença de pressão ¿pleer entre a pressão antes da conexão condutora de gás ser estabelecida e a pressão com a conexão condutora de gás à câmara de película (12) estabelecida, no caso de uma câmara de película vazia (12), sem nenhum objeto de teste (18), ser comparada com a diferença de pressão correspondente ¿pprüfling, quando um objeto de teste (18) está presente na câmara de película (12).
