(Specification)Standard Specification for Laboratory Glass Test Tubes
Standard Specification for Laboratory Glass Test Tubes
ABSTRACT
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.

5. Design
5.1 Shape—Test tubes covered by this specification shall be
tubular, with one end having a rounded closure.
5.2 Capacity—Capacities on ungraduated tubes are only
approximate, but any graduation onType II tubes shall indicate
the contained capacity within 65 % of nominal tube capacity.
5.3 TypesIandII—TheopenendofTypesIandIItesttubes
shall have a beaded rim; dimensions shall be as specified in
Table 1.
5.4 Type III—The open end of Type III test tubes shall have
a standard taper stopper. The joint and stopper shall be in
accordance with Specification E675 and Table 1.
5.5 Types IV, V, and VIII—The open end ofTypes IV,V, and
VIII test tubes shall be rimless and fire polished, dimensions
shall be as specified in Table 1.
5.6 Type VI—The open end of Type VI test tubes shall have
a standard GPI thread finish made to accommodate a plastic
screw-on type cap. The inner edge of the cap shall be
sufficiently threaded with a continuous thread formed as an
integral part of the cap. The cap shall form a close fit with the
tube to prevent loss of the contents. ClassAand B screw caps
shall be lined with tight-fitting cemented-in liner. Class C
screw caps shall be one piece and shall contain no liner.
Dimensions and threaded finish of the test tubes shall be as
shown in Table 1.
5.7 Type VII—The open end of Type VII test tubes shall
have a beaded rim and a ribbed sidearm near the open end.
Dimensions shall be as specified in Table 1.
5.8 AreaforMarking—Sidewalloftesttubes(exceptTypes
VII andVIII) may have an area that provides for marking.This
area shall be durable, fused-on white enamel or roughened by
sandblasting.
6. Identification Marking
6.1 Each test tube may be permanently and legibly marked
with the manufacturer’s name or trademark.
7. Sampling and Testing
7.1 For sampling, refer to Specification E1157.
8. Packaging
8.1 For packaging, select from Specifications E920, E921,
or Practice E1133.
