13、d under the direction of the Mechanical Engineering Standards Committee and, as foreshadowed in the foreword to the 1979 edition of Part 1 of the standard, is identical with ISO 355:1977/Addendum 2:1980 “Metric tapered roller bearings Flanged cups Boundary dimensions” prepared by Technical Committee
14、 ISO/TC 4, Rolling bearings, of the International Organization for Standardization (ISO). With regard to the reference to ISO 582, it should be noted that BS 3134-1, in which the series designations and boundary dimensions complying with ISO 355 for single row bearings were implemented, also include
15、s chamfer dimensions for tapered roller bearings. It should be noted that in ISO 355/Addendum 2 reference has been made in error to ISO/R 492 which does not apply to tapered roller bearings. The tolerances for such bearings will be specified in the current revision of that International Standard and
16、 have already been included in BS 3134-1. Terminology and conventions. The text of the addendum to the International Standard has been approved as suitable for publication, without deviation, as Part 3 of BS 3134. Some terminology and certain conventions are not identical with those used in British
17、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. Where the words “International Standard” appear, referring to this standard, they
18、should be read as “British Standard”. 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 legal obligations. Cro
