The drafts for public comment DR AS/NZS 1252.1 and DR AS/NZS 1252.2 have been published by Standards New Zealand.

The objective of these draft standards is to provide manufacturers of high-strength steel bolt assemblies with requirements and tests to ensure that such assemblies are suitable for bolted connections in steelwork construction, consistent with the steel design Standards AS 4100 and NZS 3404.

Of particular interest to designers is the nomination of bolt assemblies to EN 14399-3 Type HR property class 8.8 as an alternative assembly type, which is deemed to satisfy the requirements of AS/NZS 1252. Furthermore, it is the intention of the committee responsible (ME-029) to replace AS/NZS 1252 with the EN 14399 series, which will require further amendment of NZS 3404 and AS 4100 in the future.

The closing date for comments is 18 May 2016. Copies of the drafts may be downloaded free of charge from here.

Should you have any queries on these standards, please contact our General Manager Structural Systems Dr Stephen Hicks – who is also our representative on the ME-029 committee.
