Standard Specification for Laboratory Glass Volumetric Flasks

SCOPE
1.1 This specification covers requirements for glass volumetric flasks of precision and general-purpose grades suitable for laboratory purposes.
1.1.1 Class A—Each flask of precision grade shall be marked with the letter “A” to signify compliance with applicable construction and accuracy requirements. Flasks may be marked with an identification number (serial number) at the option of the manufacturer.
1.1.2 Class B—General purpose flasks are of the same basic design as Class A flasks. However, volumetric tolerances for Class B flasks shall be within twice the specified range allowed for Class A flasks. These flasks need not be marked with their class designation.  
Note 1—Specifications for micro volumetric flasks in sizes from 1 mL to 25 mL, inclusive, are given in Specification E237.
Note 2—The Twelfth General (International) Conference on Weights and Measures redefined the litre as a “special name for the cubic decimetre,” but agreed to permit continuance of the terms litre, millilitre, and mL, except in association with measurements of the highest precision. For volumetric glassware the difference between the old and new meanings of litre is negligible. Therefore, either mL or cm3 may be marked on ware covered by this Specification.
1.1.3 Special Size Flasks—Precision grade flasks may be manufactured with nominal capacities not listed in this standard. Such flasks shall be considered “Class A” flasks, provided they meet the accuracy tolerance of the next largest “Class A” flask appearing in Table 1 and comply with the marking requirements of 1.1.1.
1.1.4 Wide-Mouth Flasks—Requirements for insertion of tablets or capsules for assay dilution and to accommodate access of larger diameter pipets require volumetric flasks with larger necks. These flasks appear in Table 2. These flasks shall conform to the marking requirements of 1.1.1. Additionally, the accuracy tolerance shall be marked on each “Class A” wide-mouth flask.
1.1.5 Special Size Wide-Mouth Flasks—Precision grade wide-mouth flasks may be manufactured with nominal capacities not listed in this standard. Such flasks shall be considered “Class A” flasks provided they meet the accuracy tolerance of the next largest “Class A” wide-mouth flask appearing in Table 2 and the marking requirements of 1.1.4.

1. Scope
1.1 This specification covers requirements for glass volumetric flasks of precision and general-purpose grades suitable for
laboratory purposes.
1.1.1 Class A—Each flask of precision grade shall be marked with the letter “A” to signify compliance with applicable
construction and accuracy requirements. Flasks may be marked with an identification number (serial number) at the option of the
manufacturer.
1.1.2 Class B—General purpose flasks are of the same basic design as ClassAflasks. However, volumetric tolerances for Class
B flasks shall be within twice the specified range allowed for Class A flasks. These flasks need not be marked with their class
designation.
NOTE 1—Specifications for micro volumetric flasks in sizes from 1 mL to 25 mL, inclusive, are given in Specification E237.
NOTE 2—TheTwelfth General (International) Conference onWeights and Measures redefined the litre as a “special name for the cubic decimetre,” but

glassware the difference between the old and new meanings of litre is negligible. Therefore, either mL or cm may be marked on ware covered by this
Specification.

tolerance range of the next smaller volumetric standard product listed in
1.1.3 Special Size Flasks—Precision grade flasks may be manufactured with nominal capacities not listed in this standard. Such
flasks shall be considered “ClassA” flasks, provided they meet the accuracy tolerance of the next largest “ClassA” flask appearing
in Table 1 and comply with the marking requirements of 1.1.1.
1.1.4Wide Mouth—Requirements for insertion of tablet or capsule for assay dilution and to accommodate access of larger
diameter pipets have created demand for introduction of volumetric flasks provided with larger opening. Product with a stated
capacity with a wider mouth, not previously listed in this standard, may be specified classAtolerance when product conforms to
the tolerance range of the volumetric standard product listed in
1.1.4 Wide-Mouth Flasks—Requirements for insertion of tablets or capsules for assay dilution and to accommodate access of
larger diameter pipets require volumetric flasks with larger necks.These flasks appear inTable 2. In order to avoid confusion, wide
neck flask tolerance must be marked on each flask as a requirement. . These flasks shall conform to the marking requirements of
1.1.1. Additionally, the accuracy tolerance shall be marked on each “Class A” wide-mouth flask.
