Our timber certification schemes

NSAI offers the following certification schemes:

1. CE Marking of timber

• Visual Strength Grading (VSG) and Machine Strength Grading (MSG) Schemes – these schemes are offered to companies which wish to grade and stamp structural timber to the requirements of I.S. 127 and I.S. EN 14081. They provide for the control and supervision of strength grading operations by trained and certified personnel. Only certified companies are permitted to use the NSAI registered mark on graded timber.
• Roof Truss Manufacturers Approval Scheme – the function of this scheme is to ensure that all roof russes manufactured in Ireland comply with the requirements of S.R. 70 and I.S. EN 14250. The scheme provides for the certification and ongoing inspection of roof truss manufacturing plants and the inspection of fabricated trusses bearing the NSAI-approved manufacturers mark.

2. Timber Frame Manufacturers Approval Scheme – our assessment procedures and inspections verify compliance with the scheme’s requirements, which involve:

• Detailing and implementing procedures for structural design
• Specifying all materials used and ensuring their ongoing compliance with specification
• Requirements
• Documenting standard constructional details
• Providing comprehensive information about site erection

Describing and documenting in a manual the design, manufacturing and inspection procedures which comprise the company’s quality management system. 

3. Wood Pallet and Packaging Phytosanitary Marking Scheme - this scheme certifies heat-treated timber for Wood Packaging Material (WPM). It satisfies international export regulations and addresses requirements for ISPM 15 Phytosanitary controls and markings on wood pallets and packaging materials used in the export of goods to certain countries, which stipulates that all solid wood pallets and packaging must be:

• Free of bark, or debarked
