Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 12809-1991 "principles of design and construction of laboratory glassware Glass Container." And GB/T 12809-
1991 The main difference is as follows.
--- Increasing the terms and definitions;
--- Forfeited modify standard reference currently valid standards.
The standard reference method using redrafted ISO 384. 1978 "design and construction principles of laboratory glassware gauge the" establishment,
And ISO 384. 1978 of the non-equivalent.

Laboratory glassware
Design and construction principles of Glass Container
1 Scope
This standard specifies the design and construction principles of Glass Container.
This standard applies to capacity range in 0.1mL ~ 2000mL glass gauges, including graduated cylinder, measuring cup, Buret, indexing straw (suck
The amount of pipe), a single marking pipette (pipette) and the flask and the like.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.
GB/T 21297 tapered frosted glass laboratory equipment swap connector
GB/T 28214 Laboratory glassware color-coded pipette
3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Unit of capacity capacityunits
Capacity measuring unit milliliter (mL) or cubic centimeter (cm3). Also available cubic decimeter (dm3) or cubic millimeters under special circumstances
(Mm3), i.e. liters (L) or microliters (μL).
3.2
Standard temperature standardtemperature
Temperature of the glass used to gauge or measure out the amount of its nominal volume (capacity) when, as 20 ℃.
Accuracy 4 Capacity
4.1 When a specification is required, there are two levels of accuracy, the higher should be labeled as "A-class"; a lower level shall be marked as "B-class."
4.2 Capacity tolerance should be determined according to the method used for each gauge, objects, and levels of accuracy.
4.3 Glass Container capacity usually tolerance value should be a multiple of the number of columns or a suitable 10-12-15-20-25-30-40-50-60-80 10
Select.
Note. This is the preferred value of R10 series, using it, in order to avoid certain non-integer (eg 31.5) decimal precision value factor, in fact, it will not be able
measure.
4.4 pairs of a series of specifications of the measure and the provisions of the capacity of tolerance as shown in Appendix A logarithmic chart, should provide an appropriate and uniform
series. The chart should include as an appendix in a predetermined gauge all the technical requirements of 3 or more of the specifications.
4.5 equiv has A, B two levels of accuracy when, B-level capacity tolerance should normally be approximately twice the A-level tolerances.
4.6 With the division of the table the measure and any level of accuracy of the maximum capacity of tolerance should not normally exceed the capacity of its minimum scale values.
