Why Certifications Matter for Acoustic Panels

Certifications provide objective proof that acoustic panels:

• Perform as claimed

• Are safe for indoor use

• Comply with local building regulations

• Meet international quality and sustainability standards

For architects, contractors, distributors, and importers, certified acoustic panels reduce project risk and ensure long-term reliability.

1. Acoustic Performance Certifications (Sound Absorption)

NRC (Noise Reduction Coefficient)

One of the most important certifications for acoustic panels is NRC, which measures how effectively a panel absorbs sound.

• NRC ranges from 0.0 to 1.0

• Higher NRC = better sound absorption

• Tested in certified acoustic laboratories

High-quality wood slat acoustic panels and polyester fiber acoustic panels are typically designed to achieve excellent NRC ratings, making them suitable for offices, theaters, studios, and residential spaces.

2. Fire Resistance Certifications

Fire safety is essential, especially for commercial and public buildings.

Common international fire standards include:

• Class A / Class B fire rating

• EN 13501 (EU fire classification)

• ASTM E84 (USA flame spread test)

Certified fire-resistant acoustic panels help meet local building codes and improve overall safety without sacrificing acoustic performance.

3. Environmental & Sustainability Certifications

As sustainability becomes a global priority, environmental certifications are increasingly important.

Key certifications include:

• FSC (Forest Stewardship Council) for responsibly sourced wood materials

• Recycled content certification (especially for polyester fiber panels)

• Low VOC or formaldehyde emission compliance

Eco-certified acoustic panels contribute to healthier indoor environments and support green building initiatives.

4. Indoor Air Quality & Health Certifications

Acoustic panels are often installed indoors for long periods, making air quality critical.

Important indicators include:

• Low formaldehyde emissions

• Non-toxic adhesives and finishes

• Compliance with international indoor air quality standards

These certifications are especially relevant for schools, offices, homes, and healthcare environments.

5. Quality Management System Certifications

Beyond individual product testing, factory-level certifications demonstrate a manufacturer’s ability to deliver consistent quality.

ISO 9001 – Quality Management System

ISO 9001 certification confirms that a manufacturer:

• Follows standardized production procedures

• Maintains strict quality control

• Ensures consistent product performance across large orders

This is particularly important for overseas buyers and long-term partners.
