It is,identical with ISO 3506-1979 'Corrosion-resistant stainless steel fasteners— Specifications,. The United Kingdom has,taken an active part of the work of Technical Committee ISO/TC 2, Fasteners, of the International Organization for,Standardization (ISO),Terminology and conventions. The text of the international 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 in,British Standards; attention is especially drawn to the following.,The comma has been used throughout 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 words 'International Standard' appear, referring to this standard, they should be read as 'British,Standard'.,Cross-references,International standard,ISO 68-1973,ISO/R 80-1968,ISO/R 81-1967,ISO 82-1974,IS0 262-1973,ISO 898/1-1978,ISO 898/11-1969,(Revised as,ISO 898/2-1 980),ISO 3651/2-1976,Corresponding British Standard,BS 3643 ISO metric screw threads,Part T : 1 981 Principles and basic data,(Technically equivalent),BS 891 Method for Rockwell hardness test -,Part 1 :1 962 Testing of metals .,(Technically equivalent),BS 427 Method for Vickers hardness test,Part 1 : 1 961 Testing of metals,(Technically equivalent),BS 18 Methods for tensile testing of metals,Part 2 :1 97 1 Steel (general),(TechnicaIFy equivalent),BS 3643 ISO metric screw threads,Part 1 :1981 Principles and basic data,(Technically equivalent),BS 61 04 Mechanical properties of fasteners,* Part 1 :1981 Specificat'ron for bolts, screws and studs,(Identical),BS 6104 Mechanical properties of fasteners,*Part 2 : Specification for nuts with specified proof load values,(Technically equivalent),BS 5903 : 1 980 Method for determination of resistance to intergranular corrosion of,austenitic stainless steels: copper sulphate —sulphuric acid method,(Moneypenny Strauss test),(Technically equivalent),The Technical Committee has reviewed the provisions of ISO/R 79-1 968 referred to in the text, and has decided that,they are acceptable for use in conjunction with this standard.,The British Standard related to ISO/R 79 is BS 240 : Part 1 : 1 962一,There is no corresponding British Standard for ISO 3651/1-1976. The committee responsible for it having been,consulted, its technical requirements are hereby confirmed as being acceptable, and insofar as it is called up in the main,body of this standard as a requirement to be complied with, it is to be regarded as mandatory forth. purposes of this,standard.,There are no corresponding British Standards for ISO 683/XIII-1974 and ISO 4954-1 979.
