This specification covers glass test tubes suitable for laboratory use. The test tubes shall be of the following classification according to size: Type I, Type II, Type III, Type IV (Class A, Class B, and Class C), Type V, Type VI, and Type VII. Test tubes shall be made of the prescribed borosilicate glass (Type I glass) or of soda-lime glass (Type II glass) and shall be tubular, with one end having a rounded closure. The following are specified: (1) material requirements for screw caps, liners, and annealing and (2) design requirements for the test tube capacity, dimensions (OD, length, and wall thickness), and area for marking. Other dimensional requirements such as subdivision, stopper, and GPI thread finish are also specified.
