Standard Specification for Laboratory Glass Graduated Cylinders

ABSTRACT
This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades. The graduated cylinders may be in one of three styles; beaded lip with spout, grounded standard taper neck, or beaded lip with pour spout and reinforcing band near the top. The products should conform to the required cylinder and base shapes, dimensions, quality of gradation and identification markings, and length of gradation lines.
SCOPE
1.1 This specification covers requirements for glass graduated cylinders for precision and general purpose grades suitable for laboratory purposes.  
1.1.1 Class A—Each cylinder of precision grade shall be marked with the letter “A” to signify compliance with applicable construction and accuracy requirements. Cylinders may be marked with an identification number (serial number) at the option of the manufacturer.  
1.1.2 Class B—General purpose cylinders are of the same basic design as Class A cylinders. However, volumetric tolerances for Class B cylinders shall be within twice the specified range allowed for Class A cylinders. These cylinders need not be marked with their class designation.  
1.1.3 Product with a stated capacity not listed in this standard may be specified in class A tolerance when product conforms to the tolerance range of the next smaller volumetric standard product listed in Table 1.TABLE 1 Dimensions and Tolerances
