Abstract:
A method for obtaining gas samples from a blister in a pneumatic tire at elevated temperatures comprising the steps of(a) preheating a gas tight syringe, said syringe comprising a barrel, a plunger within said barrel and extending from a first end thereof, and a hollow needle which is in communication with the inside of said barrel attached to a second end thereof, in a heating block to a temperature of within .+-.10.degree. C. of the expected temperature of a sample(b) penetrating said blister with said needle and inserting the needle into gases which are to be sampled and analyzed(c) withdrawing said plunger from said barrel a specified distance to obtain a specific size sample of gases,(d) removing said needle from said gases, and(e) placing a syringe containing a sample in a heating block to maintain the temperature of said sample for analysis.
