8、s Committee, is identical withISO 6414:1982 “Technical drawings for glassware” published by the International Organization for Standardization (ISO). ISO 6414 was prepared asa result of discussion in ISO Technical Committee 10, Technical drawings, inwhich the UK participated. In 1994 the European Co
9、mmittee for Standardization (CEN) accepted ISO6414:1982 as European Standard EN ISO 6414:1994. As a consequence ofimplementing the European Standard this British Standard is renumbered asBSEN ISO 6414:1995 and any reference to BS 2774 should be read as a referenceto BS EN ISO 6414:1995. BS 2774 was
10、first published in 1956. Investigations had shown that the established conventions of engineering drawing were not necessarily applicable to glass apparatus and that alternative conventions had not been codified or generally adopted, even though some were well established. BS 2774:1956 was issued to
11、 standardize drawing conventions for glassware and was intended to supplement the established points of drawing conventions given in BS 308 “Engineering drawing practice”. In the period from 1956 to 1982, a number of International Standards covering various aspects of technical drawing were publishe
12、d and others were in the course of preparation 1) . Also, BS 308 was revised in 1964 and again in 1972 to bring thestandard into line with ISO recommendations and to minimize divergences between the national standards of the USA, Canada and the UK. In this revision of BS 2774 the text has been simpl
13、ified and no longer includes information which is not specific to drawings of glassware and/or which may be found in other British and International Standards. This revision supersedes the previous edition of BS 2774, which is now withdrawn. Terminology and conventions. The text of the International
14、 Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used inBritish Standards; attention is especially drawn to the following. The comma has been used as a decimal marker. In British Sta
15、ndards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. 1) See clause 2 and Annex.

British Standards which are related to ISO 383, ISO 641, ISO 3898 and ISO 4793 are respectively BS 572 “Interchangeable conical ground glass joints”, BS 2761 3)“Spherical ground glass joints”, BS 1991 “Letter symbols, signs and abbreviations” Part 4 “Structures, materials a

Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
24、concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its
25、 own language and notified to the Central Secretariat has the same status as the official versions.

30、the figures merely illustrate the text and should not be considered as design examples. For this reason the figures are simplified and are not to scale. For uniformity all figures in this International Standard are in first angle projection. It should be understood that alternative projection method
31、s could have been used without prejudice to the principles established. 1 Scope and field of application This International Standard establishes rules and conventions for particular use with drawings for technical glassware, for example laboratory glassware or glassware used in other technical field
32、s. Optical parts are not however, included herein. 2 References ISO 128, Technical drawings General principles of presentation. ISO 129, Technical drawings Dimensioning 4) .

For additional information, see the Annex. 3 General 3.1 As a general principle, all glassware shall be drawn
34、 as if it were non-transparent (opaque), seeISO 128. 3.2 In order to meet particular requirements for the design and manufacture of glassware, additional rules and conventions are specified in the following clauses. 4 Sections 4.1 Small sections may be blackened, provided that the distance between t
35、heir outlines on the actual drawing is not larger than 3 mm. If larger, the section shall be hatched. For thin-walled parts, see6.1. 4.2 Parts of different materials such as glass-metal seals which are fused together and shown in section, shall be hatched differently (see Figure 1). 5 Treated parts
36、5.1 Treated surfaces (for example ground, silver-plated, etched) shall be indicated in accordance with ISO 128, ISO 129 and ISO 1302 (see Figure 2). 5.2 Interchangeable conical or spherical ground joints complying with the requirements of ISO 383 and ISO 641 respectively, shall be designated in the
37、manner described therein. Accordingly, no detailed dimensioning of that portion and no indication of the surface finish are required. An example of a code identification for interchangeable conical ground joints is shown inFigure 3. 4) At present at the stage of draft. (Revision of ISO/R 129:1959.)
38、Figure 1 Figure 2 Figure 3 ENISO6414:1994 4 BSI 03-2000 6 Thin walls 6.1 When drawn in section, thin walls shall be represented, in spite of their real wall thickness, by lines with a thickness of at least twice that used for visible outlines (see Figure 4 and Figure 5, and 4.1). 6.2 Unless otherwis
39、e specified (see 6.3), the dimension shown for the diameter of thin walls shallbe the external diameter (see Figure 6 and Figure 7). The method to be applied depends on the particular requirement of the drawing. If it is necessary to specify the wall thickness, thisshall be done as shown in Figure 7
40、. 6.3 Internal diameters shall always be designated with the letters “int.” (see Figure 8). 7 Tubes 7.1 Ends of tubes with special features (for example holes or closed ends) shall be drawn in section (seeFigure 8). 7.2 Coiled tubes represented in section or in view,may be drawn in a simplified mann
41、er (seeFigure 9 and Figure 10). Their dimensioning should be determined by the functional requirements or the method of manufacture. Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 ENISO6414:1994 BSI 03-2000 5 8 Sintered filters When drawn in section sintered filters are indicated in a simplif
42、ied manner by means of random dotting 5) (see Figure 11). Any other details shall be indicated separately in accordance with ISO 4793. 9 Joints 9.1 Where fused joints are to be shown in section, indicate the joint as shown in Figure 12. 9.2 Where joints are cemented, the specification ofthe adhesive
43、 should be indicated as shown in Figure 13. Figure 10 5) In order to permit copying of any drawing, the dotting shall be very clear. Figure 11 Figure 12 2)Specification of the adhesive. Figure 13 ENISO6414:1994 6 BSI 03-2000 9.3 Removable parts such as stop-cocks, stirrers, and gland assemblies shal
44、l be drawn clearly spaced from each other as shown in Figure 14, Figure 15 and Figure 16. This will avoid ambiguity as to whether the parts are or are not fused together. 10 Composite glassware When it is necessary to represent in detail one or more component parts of composite glassware which consi
45、sts of sealed parts, the drawing of the complete composite glassware may be simplified by separating the details with their dimensions for drawing clarity, as shown in Figure 17.
