7、ttee, is based on ISO5830:1984 published by the International Organization for Standardization (ISO). It differs from the International Standard in specifying material that complies with BS4577 rather than ISO5182, since the requirements for softening temperature in BS4577 are generally more stringe

8、nt than those 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 This British Standard is being revised in several Parts and supersedes BS4215:1967, which is withdrawn.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 Intern

9、ational Standard, 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

13、. The text of ISO5830:1984 has 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 St

14、andards it is current practice 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 o

15、f itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 and 2, an inside back cover and a back cover.

17、de adaptor (see BS4215-6). It only applies to electrode caps for which the electrode force F max , given for the diameter d 1 , does not exceed4,0 kN. 2 References The titles of the publications referred to in this standard are listed on the inside back cover. 3 Dimensions The dimensions shall be th

18、ose given in theFigure and theTable. 4 Designation Electrode caps covered by this Part of BS4215 shall be designated by noting in order: a) the reference to this Part of BS4215; b) the external diameter, d 1 ; c) the length, l 1 . Example: Designation for a male electrode cap for spot welding type L
