(Specification)Standard Specification for Laboratory Glass Multiple Neck Distilling/Boiling Flasks
Standard Specification for Laboratory Glass Multiple Neck Distilling/Boiling Flasks
ABSTRACT
This specification provides the standard appearance, capacity, design, and dimensional requirements for eight types of multiple neck distilling/boiling glass flasks for laboratory use. Flasks, which shall be made of borosilicate glass conforming to specified maximum residual thermal stresses, are available in the following types: Type I, standard taper necks of equal height; Type II, three tooled necks of unequal height; Type III, three standard taper necks of unequal height; Type IV, three standard taper necks of equal height; Type V, three tooled necks that are angled; Type VI, three standard taper necks that are angled; Type VII, two standard taper necks of unequal height; and Type VIII, two standard taper necks that are angled.
SCOPE
1.1 This specification provides standard dimensional requirements for multiple neck distilling/boiling flasks.
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 accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
