7、 based on ISO5184:1979 published by the International Organization for Standardization (ISO). It differs from the InternationalStandard in specifying material that complies with BS4577 rather than ISO5182, since the requirements for softening temperature in BS4577 are generally more stringent than t
8、hose in ISO5182. This British Standard is being revised in several Parts and supersedes BS4215:1967, which is withdrawn. Most of the Parts will be identical with or based on International Standards but, in instances where the UnitedKingdom was unable to give a vote of approval to the International S
9、tandard, a corresponding British Standard will be prepared, where possible, taking account of the reasons for disapproval. A further Part will also be published in due course, specifying electrodes, electrode holders and ancillary equipment of interest in the UK only. The following Parts of BS4215 h

The text of ISO5184:1979 has
13、been used for ease of production of this Part of BS4215, although some terminology 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
14、to use a full point on the baseline as the decimal marker. 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 does not of itself confer immunity from l
15、egal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 and2, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment tab
16、le on the inside front cover.BS4215-2:1987 BSI 08-1999 1 1 Scope and field of application This Part of BS4215 lays down the dimensions and tolerances of straight resistance spot welding electrodes. It applies only to straight spot welding electrodes, where the electrode force F maxgiven for diameter
