21、 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used
22、 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 documents should be noted. This document was drafted in accordance with the editorial rules of

28、eneral laboratory use. These bottles with nominal volumes ranging from 25 ml to 20 000 ml are also suitable for the preparation and storage of microbiological growth media.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispen

31、.3.3 The design of the bottle shall be such that the total capacity to the base of the neck shall be approximately 15 % greater than that to the shoulder.4 DimensionsThe dimensions and tolerances of screw-neck bottles are given in Figure 1, Figure 2, and Table 1.Table 1 DimensionsNominal capacityTot

35、truction5.1 Material5.1.1 Bottles shall be constructed of clear, colourless or amber borosilicate glass 3.3 in accordance with ISO 3585.5.1.2 Internal stress and visible defects in the glass (such as bubbles near the surface) shall be reduced to a level sufficient to minimize the possibility of frac
36、ture due to thermal or mechanical shock.5.2 Design5.2.1 The base of the bottle shall be constructed so as to enable the bottle to stand firmly on a flat surface without rocking or spinning.5.2.2 The base of the bottle shall have a suitable radius so as to provide a smooth transition between the base
37、 and the side. The main portion of the side shall be cylindrical for bottles with nominal capacities of 25 ml to 2 000 ml, and slightly tapered for bottles with nominal capacities 3,5 l to 20 l with the smaller diameter at the base of the bottle.The diameters d1shall be as given in Table 1.5.2.3 The
38、 shoulder of the bottle shall have a suitable radius in order to provide a smooth transition between the side and the conical upper proportion of the bottle.DIN EN ISO 4796-1:2016-11 EN ISO 4796-1:2016 (E) 7 5.2.4 The upper portion of the shoulder shall be of conical shape. The transition radius fro
39、m the shoulder to the neck shall be as small as possible to be compatible with manufacturing practice.5.2.5 The bottle shall be blown so as to evenly distribute the glass in the mould avoiding sudden changes in the wall thickness. The thinnest areas shall not have a thickness less than the minimum v
40、alue specified in Table 1.5.2.6 The neck of the bottle shall be stoutly constructed and finished with a strengthening lip designed to facilitate pouring without liquid running down the outside of the bottle. A clip-on anti-trip ring of plastics material fitting into a slightly recessed channel on th
41、e outside of the neck is a permitted alternative form of construction.NOTE There are suitable national standards for the dimensions and design of the thread of the screw neck.5.2.7 The outer glass surface of the bottles may be coated with a suitable plastics material as a protection and to limit lea
42、kage of liquid if the bottle is damaged. The coating shall be resistant to steam sterilization at 135 C.5.3 ClosuresBottles shall be provided with closures of a suitable inert plastics material, e.g. polypropylene. Closures shall form a liquid-tight seal with the threaded bottle neck.6 DesignationIf
43、 a designation of bottles is required, this shall be by reference to this part of ISO 4796, i.e. ISO 4796-1, together with the nominal capacity of the bottle.EXAMPLE For a bottle with a nominal capacity of 500 ml, the designation would be as follows:Laboratory bottle ISO 4796-1 5007 Marking7.1 Bottl
44、es complying with this part of ISO 4796 shall be marked with the following:a) nominal capacity;b) makers and/or vendors name and/or trade mark;c) number of this International Standard, i.e. ISO 4796-1, or appropriate reference to the correspondending national standard.In addition, each bottle can be
45、ar an area with a surface suitable for marking with a pencil.Marks a) to c) may be moulded into the recessed base of the bottle, if the method of manufacture permits; otherwise, they may be indelibly marked, in any convenient position, by etching, sandblasting or with vitreous enamel.7.2 The closure
46、s of the bottles shall be marked with the maximum permitted temperature for use or for sterilization, e.g. “max. 100 C”.NOTE Closures not marked with a temperature can only be used at ambient temperature.During sterilization, the closure may not be screwed more than one turn to enable pressure release. Otherwise, pressure increase in the bottle can result in fracture.DIN EN ISO 4796-1:2016-11 EN ISO 4796-1:2016 (E) 8
