Welcome to the WTCCC

The objective of certification of metal-plate-connected wood trusses is to allow manufacturers the ability to demonstrate to the market that their product as been attested to fulfil the requirements of CSA S349:20 by an impartial third-party body. Product certification provides confidence for those with an interest in fulfillment of the requirements.

Scope of the WTCCC

Regional Auditing Organizations (RAO's)

​The scope of the WTCCC scheme is limited to metal-plate-connected wood trusses manufactured in Canada certified to CSA S349:20 standard.

As metal-plate-connected trusses are manufactured individually for each application and can not be practically inspected individually the CSA S349:20 standard outlines a process of auditing a manufacturer’s quality management system. This includes documentation reviews of internal product inspections, review of their quality manual, review of a sampling of design drawings, observations of material storage and handling, and auditor random reviews of finished product.
​
The WTCCC standard outlines the auditing process for certification, including requirements for approved Regional Audition Organizations (RAO's) to oversee the auditing process.

The WTCCC utilizes RAO's for auditing activities​.

• Conduct audits using WTCCC’s standardized audit tools, checklists and procedures.
  
• Report findings to WTCCC in a harmonized format.
  
• Remain impartial and separate from certification decision-making.
  
• Maintain auditor competency through their own requirements  and WTCCC training.
