National Highways Sector Scheme 20, NHSS 20, updated to add ISO 3834 certification

Highways England has updated the National Highways Sector Scheme 20 document, also known as NHSS 20, which sets out the additional requirements for quality management systems, over and above ISO 9001:2015, for the production of steel work for transportation infrastructure such as bridges. In addition to EN 1090-1 & ISO 9001, fabrication companies working in this sector will need separate certification to the ISO 3834 welding quality management standard, by 1st September 2020.
