ABSTRACT:
A method of testing products capable of being inflated and in particular surgical gloves which involves applying a normally destructive gas pressure thereto while the same is being constrained against substantial inflation and detecting the degree of leakage of the gas owing to leakage flaws or rupture of weak spots and either passing or rejecting the product on the basis thereof. In order to obtain an accurate result the method and the apparatus for performing the method first applies a pressure to the product higher than that from which testing will commence and thereafter reduces the same to the commencement pressure so as to minimize the effect of stress relaxation and creep of the material from which the product is formed.
