The work of preparing International Standards is normally carried out through ISO technical committees. Each member body int
21、erested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnic
22、al Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO docu
23、ments should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsib

27、lowing changes: additional series with thick-walled beakers has been added; dimensions and tolerances have been adjusted to state of manufacturing; beakers with a nominal capacity of 500 ml, 5 000 ml, and 10 000 ml have been added; thermal shock resistance has been modified.DIN EN ISO 3819:2016-05EN
28、 ISO 3819:2015 (E)4 1 ScopeThis International Standard specifies requirements for an internationally acceptable series of glass beakers for laboratory use.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its app
29、lication. For dated references, only the edition cited applies.

30、pes of beakersThe following three types of beakers are specified:a) low-form beaker with spout;b) low-form beaker with spout, thick-walled;c) tall-form beaker with spout.4 Series of beakersThe series of beakers covered by this International Standard and defined by type and nominal capacity shall be
31、as follows:a) low-form beakers: 5 ml 10 ml 25 ml 50 ml 100 ml 250 ml 400 ml 500 ml 600 ml 800 ml 1 000 ml 2 000 ml 3 000 ml 5 000 ml 10 000 ml;b) thick-walled low-form beakers: 150 ml 250 ml 400 ml 600 ml 1 000 ml 2 000 ml 5 000 ml;c) tall-form beakers: 50 ml 100 ml 150 ml 250 ml 400 ml 500 ml 600 m
32、l 800 ml 1 000 ml 2 000 ml 3 000 ml 5 000 ml.5 CapacityThe design of the beaker shall provide for the difference in volume between nominal capacity and overall capacity. The capacity of the beaker shall be determined by either one of the following relationships:a) overflow of capacity of a beaker sh
33、all exceed the nominal capacity by at least 5 %;b) distance between the levels corresponding to the nominal and overflow capacities shall be at least 10 mm.Whichever of these two relationships produces the greater differential in capacity shall apply.DIN EN ISO 3819:2016-05EN ISO 3819:2015 (E)5 6 Ma
34、terialBeakers shall be made of borosilicate glass 3.3 in accordance with ISO 3585. The glass shall be reasonably free from residual strain and from visible glass defects which might impair the safety and performance of the beaker.7 Dimensions7.1 GeneralLow-form and tall-form beakers shall observe th
35、e dimensions specified in Table 1 and thick-walled beakers the dimensions specifed in Table 2. The tolerances on the external diameter shall be 5 % of the value given in the tables.NOTE This considerably large tolerance has been specified to enable beakers of different manufacturers around the world
36、 to comply with this International Standard. This tolerance is not intended as manufacturing tolerance which usually is much tighter.7.2 Radius at baseBeakers having a nominal capacity of 250 ml or greater shall have an external radius at the junction between the base and the side of 10 % to 20 % of
37、 the external diameter.Beakers having a nominal capacity less than 250 ml shall have a minimum radius at the junction between the base and the side of 5 % of the external diameter.7.3 Wall thicknessSubstantial local irregularities from the minimum values for wall thickness given in the tables shall
38、be avoided. That means, the minimum wall thickness shall fall at no place below the values given in Table 1 and Table 2 and the beakers shall comply with the requirement for thermal shock endurance specified in 8.5.Table 1 Dimensions for low-form and tall-form beakersType Nominal capacity mlExternal

42、 BaseThe design of the base shall enable the beaker to stand vertically on a plane horizontal surface without spinning or rocking.8.2 Upper edgeThe side of the beaker shall be slightly flared near the brim in a smooth and regular curve. The diameter of the brim shall be of the order of 5 % to 15 % g
43、reater than the diameter of the body. The edge of the brim shall be finished in a plane parallel with that of the horizontal base.8.3 SpoutThe spout shall be shaped so that, when the beaker is filled with water, the water may be poured in a regular stream clear of the side of the beaker. When the be
44、aker is placed on a horizontal surface and filling is continued beyond its overflow capacity, the water shall first overflow from the spout and not from any other part of the brim.Table 1 (continued)DIN EN ISO 3819:2016-05EN ISO 3819:2015 (E)7 8.4 ScaleBeakers may be provided with a scale, which sho
45、uld approximately indicate the volume contained in the beaker.8.5 Thermal shock resistanceBeakers shall have a thermal shock resistance of 160 C when tested in accordance with ISO 718.9 MarkingThe following inscriptions shall be permanently and legibly marked on all beakers:a) nominal capacity of th
46、e beaker, for example “100 ml” (or 100), and the scale, if marked on the beaker;b) makers and/or vendors name and/or mark;c) type of glass, if not identifiable otherwise.In addition, each beaker shall bear an area with a surface suitable for marking with pencil.DIN EN ISO 3819:2016-05EN ISO 3819:2015 (E)8
