1. Scope
1.1 This specification provides standard dimensional re- quirements for glass beakers suitable for general laboratory use. N OTE 1—For packaging standards, choose among the following stan- dards: Specification E920, Specification E921, Practice E1133. For sampling and testing refer to Specification E1157. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Material and Annealing
4.1 Beakers shall be made of borosilicate glass conforming to the requirement of Type I, Class A of Specification E438. 4.2 Maximum residual thermal stress shall be such as to conform to Specification E671.
5. Design
5.1 Types I and II beakers shall be constructed to have straight sides (the 1 000 through 4 000 cm 3 sizes may have slightly tapered sides). Types III and IV beakers shall have slightly tapered sides (the 100 and 200 cm 3 may be straight sided). Type V beakers may have slightly tapered or straight sides. 5.2 All styles may have a slightly concave bottom. The junction of the sides with the bottom shall be well rounded. 5.3 The beakers shall be symmetrically made and smoothly finished, the upper edge with a fire polished bead and may be flared outward. Type II beakers may have a tooled flare. 5.4 Types I, II and III beakers shall have well defined spouts such that the stream of water poured from the lip of the beaker shall pour evenly, and shall not cling to the outside of the beaker and flow off the bottom when tilting the nearly full beaker at a 45° angle.
6. Capacity and Dimensions
6.1 Beakers shall conform to the requirements of Table 1, Table 2, Table 3, and Table 4.
7. Markings
7.1 Each beaker shall be permanently marked with the name or known trademark of the manufacturer and the nominal capacity, as well as approximate graduation markings that have a limit of error of 65 % of full capacity. The graduation intervals shall comply with the tables. 7.2 There shall be an area on one side of the beaker, roughened by sand blasting or suitably decorated to provide for marking with pencil.
