It is identical to ISO 898‑3:2018.The UK participation in its preparation was entrusted to Technical Committee FME/9, Fasteners.A list of organizations represented on this committee can be obtained on request to its secretary.BSI, as a member of CEN, is obliged to publish EN ISO 898‑3:2018 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard.FME/9 voted to disapprove this standard for the following reason.Table 1 of ISO 898‑3:2018 does not permit 100 HV washers to be used with 8.8/8 bolt and nut assemblies or with 10.9/10 bolt and nut assemblies.Bolt, nut and washer assemblies using these washers are permitted in accordance with the cited harmonized standard EN 15048‑1:2007 (see EN 15048‑1:2007, Table 6), and are required for use in structural connections as speciied in EN 1090‑2, Execution of steel structures and aluminium structures – Part 2: Technical requirements for steel structures .These assemblies are used extensively in non‑preloaded structural bolting in the UK and have been used successfully for well over 40 years. The function of the washers in these non‑preloaded structural bolting assemblies is solely to reduce local damage to metal coatings applied to the structural steelwork, and there is therefore no technical justiication for prohibiting the use of 100 HV washers for these assemblies.Note: EN 15048‑1:2016 and EN 15048‑2:2016 have been published but the harmonized standard EN 15048‑1:2016 has not yet been cited. Requirements concerning washers have been removed from EN 15048‑1:2016 but the requirements concerning the use of 100 HV washers with 8.8/8 bolt and nut assemblies or with 10.9/10 bolt and nut assemblies are retained in EN 15048‑2:2016 (see EN 15048‑2:2016, Clause 5.2)FME/9 recommends that for all structural bolting assemblies required for EN 1090‑2 connections the requirements of ISO 898‑3:2018 should be disregarded.This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.© The British Standards Institution 2018   Published by BSI Standards Limited 2018ISBN 978 0 580 92823 9ICS 21.060.20 Compliance with a British Standard cannot confer immunity from legal obligations.
