It is identical with IS0 594-1 : 1986, published by Technical Committee 84 Syringes for medical use and needles for injection of the International Organization for Standardization (ISO). BS 3930 Speci
7、fication for conical fittings with 6 per cent (Luer) taper for hypodermic and other surgical equipment was first published in 1965 and specified requirements for Luer slip fittings made of rigid materials, e.g. metal, glass. This standard is the first Part of a two-part revision of BS 3930 : 1965 an
8、d specifies requirements for Luer slip fittings made of rigid and semi-rigid materials. It supersedes BS 3930 : 1965, which is withdrawn. The second Part of this revision will specify requirements for Luer lock fittings (which were not covered in the 1965 edition), and will implement IS0 594/2. This
9、 Part of BS 3930 also supersedes the requirements for Luer slip fittings made of semi-rigid materials given in BS 5081 : 1976 Sterile hypodermic syringes and needles for single use. BS 5081 is itself being revised in two Parts so as to take account of IS0 7864 Sterile hypodermic needles for single u
10、se and IS0 7886 Sterile hypodermic syringes for single use and to delete the dimensional requirements for Luer fittiiigs. In 1993 the European Committee for Standardization (CEN) accepted IS0 594-1 : 1986 as European Standard EN 20594-1 : 1993. As a consequence of implementing the European Standard
11、this British Standard is renumbered as BS EN 20594-1 and any reference to BS 3930 : Part 1 should be read as a reference to BS EN 20594-1. Terminology and conventions. The text of the international standard has been approved as suitable for publication as a British Standard without deviation. Some t
12、erminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the
13、words this part of IS0 594 appear, they should be read as this Part of BS 3930. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled International Standards Co
14、rrespondence Index, or by using the Find facility of the BSI Standards Electronic Catalogue. Additional information. With reference to the table of dimensions, dimension F is not intended to proscribe fittings which are only tapered to the depth of socket equivalent to the maximum length of engageme
15、nt and which are not tapered for the remainder of the minimum depth of the fitting. The IS0 text will be amended to take account of this when the standard is revised. Compliance with a British Standard does not of itself confer immunity from legal obligations. I *in preparation. Q BSI 1998 Issue 1,
