4、No. 1 5 October 2001 Incorporating annex ZA. National foreword This British Standard is the official English language version of EN ISO 4796-3:2000. It is identical with ISO 4796-3:2000. The UK participation in its preparation was entrusted by Technical Committee LBI/36, Laboratory glassware and rel
5、ated apparatus, to Subcommittee LBI/36/2, General laboratory glass and plastics ware, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK inter
6、ests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include
7、an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards C
8、orrespondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard doe
9、s not of itself confer immunity from legal obligations.

19、SO47963:2000 ii ENISO47963:2000 ISO -69743:(0002)E iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees.
20、 Each member body interested 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 Interna
21、tional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies
22、 for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 4796 may be the subject of patent rights. ISO shall not be held responsible for identifyin
23、g any or all such patent rights. International Standard ISO 4796-3 was prepared by Technical Committee ISO/TC 48, Laboratory glassware and related apparatus, Subcommittee SC 2, General laboratory glassware (other than measuring apparatus). ISO 4796 consists of the following parts, under the general
24、title Laboratory glassware Bottles: Part 1: Screw-neck bottles Part 2: Conical neck bottles Part 3: Aspirator bottles ENISO47963:2000 ENISO47963:2000 INTENRATIONAL TSANDADR ISO -69743:(0002)E 1 Laboratory glassware Bottles Part 3: Aspirator bottles 1 Scope This part of ISO 4796 specifies a series of
25、 aspirator bottles with a screw neck or with a conical neck suitable for the delivery of liquid chemicals and reagents in general laboratory use. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of I
26、SO 4796. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 4796 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated belo
27、w. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

28、art 1: Screw-neck bottles. ISO 4796-2:2000, Laboratory glassware Bottles Part 2: Conical neck bottles. 3 Types and capacities 3.1 There are three types of aspirator bottles specified in this part of ISO 4796: type ASN: aspirator bottles with a screw neck; type ACS: aspirator bottles with a conical n
29、eck socket; type ACJ: aspirator bottles with an interchangeable conical ground joint. 3.2 The nominal capacities of aspirator bottles shall be chosen from the following series: 0,5 l 1 l 2 l 5 l 10 l and 20 l 3.3 The nominal capacity of an aspirator bottle indicates the quantity of liquid which a bo
30、ttle of average wall thickness shall contain when the bottle is filled to the turn of the shoulder. 3.4 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.

34、 5.2.1 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. ENISO47963:2000 ISO -69743:(0002)E 3 Dimensions in millimetres Key 1 Taper 1:30 Figure 1 Example of an aspirator bottle 5.2.2 The base of the bottle shall have
35、 a suitable radius in order to provide a smooth transition between the base and the side. The main portion of the side shall be slightly tapered with the smaller diameter at the base of the bottle. The diameter d and the heights h 1 and h 2 shall be as given in Tables 1 and 2. 5.2.3 The shoulder of
36、the bottle shall have a suitable radius so as to provide a smooth transition between the side and the conical upper proportion of the bottle. 5.2.4 The upper portion of the shoulder shall be of conical shape. The transition radius from the shoulder to the neck shall be as small as possible to be com
37、patible with good 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 values specified in Table 1. ENISO47963:2000 ISO -69743:(0002
38、)E 4 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-drip ring of plastics material fitting into a slightly recessed channel on the outside of the neck
39、 is permitted as an alternative for aspirator bottles with a screw neck. 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 for protection and to limit
40、leakage of a liquid if the bottle is damaged. The coating shall be resistant to steam sterilization at 135 C. 5.2.8 The internal surface of the conical neck socket shall be smooth, suitable to fit with a rubber stopper, or shall be finished by fine grinding. If the surface is finished, the grinding
41、shall comply with the interchangeable conical ground joints specified in ISO 383 and dimensions specified in Table 2 of this part of ISO 4796. If the socket surface is smooth, the socket dimensions shall be suited for finishing by fine grinding so as to fit an interchangeable conical ground joint sp
42、ecified in Table 1. 5.2.9 The outlet in the side wall of the bottle shall have a distance of approximately 28 mm (see Figure 1) from the bottom. The outlet shall be supplied with an interchangeable ground joint, size 19/26 or 29/32 in accordance with ISO 383, or with an external screw thread, comply
43、ing with suitable national or International Standards. 5.3 Closure for aspirator bottles with a screw neck In accordance with 5.3 of ISO 4796-1:2000. 5.4 Stoppers for aspirator bottles with a conical neck In accordance with 5.3 of ISO 4796-2:2000. 6 Designation If a designation of bottles is require
44、d, this shall be by reference to this part of ISO 4796, i.e. ISO 4796-3, together with the nominal capacity of the bottle and the type specified in 3.1. EXAMPLE For a bottle with a nominal capacity of 2 l and of type ACS (aspirator bottle with a conical neck socket), the designation would be as foll
