Today marks World Accreditation Day, an opportunity to recognise the role accreditation plays across the built environment and wider construction industry.
What is World Accrediation Day?
World Accreditation Day is held every year on 9 June and is a global initiative to promote the value of accreditation across industry, government and society.
It was originally established by the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC) and is now coordinated by the Global Accreditation Cooperation (Global ACI). At a simple level, accreditation is an independent process that verifies organisations are competent, impartial and operating to recognised standards. This is what underpins trust in things like testing results, inspections, certifications, and compliance schemes. World Accreditation Day exists to highlight that role. In practice, it focuses on how accreditation:
- Builds trust in products, services and people
- Supports regulation and compliance
- Enables fair trade and market access
- Provides confidence to consumers and businesses
- Helps validate claims around quality, safety and sustainability
For 2026, the theme is: “Innovation, Trust and Sustainability: The Power of Accreditation.”
This theme reflects how accreditation helps ensure that new technologies, environmental claims, and industry practices are credible, evidence-based and globally recognised.
The Role of Accreditation in Sound Insulation Testing
World Accreditation Day provides a useful opportunity to recognise the role accreditation plays in sound insulation testing and why it underpins the credibility of the results produced by SITMA members.
In practical terms, accreditation ensures that sound insulation testing is carried out using consistent methodologies, calibrated equipment, and by organisations that have been independently assessed against recognised standards. This is what allows results to be relied upon for Building Regulations compliance, particularly Approved Document E, where accuracy and consistency are critical.
For SITMA members, this is not a theoretical concept. It directly affects day-to-day work on site. Variations in test setup, environmental conditions or reporting could significantly impact results, and without an accredited framework there would be no reliable way to ensure consistency across different testers or projects.
The 2026 World Accreditation Day theme, Innovation, Trust and Sustainability, reflects how the sector is evolving. As construction methods change and performance expectations increase, there is greater scrutiny on evidencing compliance. Accreditation provides a structured system that supports this, ensuring that sound testing remains robust, repeatable and defensible.
Ultimately, accreditation is what allows a sound test result to carry weight beyond the individual site. It provides confidence to developers, building control bodies and clients that the outcome is based on a recognised and verified process, rather than interpretation.
SITMA itself is UKAS accredited, providing independent oversight of the scheme and ensuring that its processes operate in line with recognised standards. This adds a further level of assurance for members and the wider industry that the scheme is robust, impartial and technically credible.
