1.1This specification covers requirements for glass burets of precision and general-purpose grades suitable for laboratory use.
1.1.1Class A—Each buret of precision grade may be marked with the letter “A” to signify compliance with applicable construction and accuracy requirements in Table 1 and Table 2. Each buret may be marked with a permanent serial number at the option of the manufacturer.

1.1.2Class B—General purpose burets are of the same basic design as Class A burets. However, volumetric tolerances for Class B burets shall be within twice the specified range allowed for Class A burets. These burets need not be marked with their class designation or serial number. See Table 1 and Table 3 for tolerances and dimensional requirements.
1.1.3Product with a stated capacity not listed in this standard may be specified Class A Tolerance when product conforms to the tolerance range of the next smaller volumetric standard product listed in Table 1.
