The NASC Code of Practice was originally introduced in 2007 for system scaffolds. The scope has since been expanded to incorporate EN39 tube, EN74-1 couplers, BS2482 timber board, aluminium beams and high tensile 3.2mm tube. In 2019 the scope will be expanded to include Readylok transoms (prefabricated structural transoms or PSTs).

The rationale behind the NASC CoP audit was to introduce a level of compliance that supplier members should adhere to, with the audit covering Quality Systems & Procedures, Product Testing, Raw Material & Components and Process Control. Where appropriate relevant BS, EN & ISO Standards are utilised.

Audits are carried out by a third party consultancy company QSI Ltd at member company UK sites and at manufacturing sites worldwide. Where an NASC CoP product audit exists, supplier members are required to submit that product for audit.

Compliant products are listed on the NASC website. The audit is specific to new product at point of entry to the UK. In some instances the compliant products listed below are also supplied by other NASC hire/sale members.
