Polyester Fibre Sheet is a non-woven material made by compressing recycled polyester fibres (often from PET bottles) into dense, rigid, or semi-rigid panels. It is widely used for acoustic insulation, thermal insulation, decorative panels, and wall/ceiling linings.

Important Test Reports & Certificates for Polyester Fiber Sheet
1. NRC Report (Noise Reduction Coefficient) – Acoustic Performance
- What is it?
The Noise Reduction Coefficient (NRC) is a rating that shows how much sound a material absorbs. Values range from 0 (no absorption) to 1 (full absorption). - Standard Testing Method:
- ASTM C423 (Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method)
- ISO 354
- Typical Values for Polyester Fiber Panels:
- 6mm sheet: NRC ~ 0.30
- 9mm sheet: NRC ~ 0.50–0.65
- 12mm sheet with air gap: NRC ~ 0.75–0.90
- Why it matters:
Higher NRC helps reduce echo and reverberation in a room, making it ideal for theaters, offices, and studios. - Ensure Supplier Provides:
- Test lab certificate (e.g., from ARAI, NABL lab, or Intertek)
- Testing based on ASTM C423 or ISO 354
2. Fire Retardancy Certificate
- What is it?
Verifies that the sheet is fire-resistant or self-extinguishing. Important for safety compliance in public buildings. - Standard Testing Methods:
- ASTM E84 (USA) – Surface Burning Characteristics
- EN 13501-1 (Europe) – B-s1, d0 is common class
- IS 15061 or IS 11871 (India)
- Fire Rating Classes:
- Class B1: Flame-retardant
- Class B2: Normal flammability
- Class A: Non-combustible (rare for fiber panels)
- ✅ Ensure Supplier Provides:
- Certified test report from a government-approved lab (like SGS, Intertek, ARAI)
- Specifies flammability rating, smoke emission, and burning time
3. Density and Strength Test Report
- What is it?
Shows the material’s compressive strength, tensile strength, and overall density (kg/m³), which affects acoustic and durability properties. - Typical Values:
- Density: 120–220 kg/m³
- Tensile Strength: Moderate (non-tearable in normal handling)
- Compression Strength: Withstands mild load pressure without deformation
- Standard Testing Methods:
- ISO 845 for Density
- ISO 1798 / ASTM D3574 for Tensile Strength
- IS 2380 or ISO 3386 for Compression
- ✅ Ensure Supplier Provides:
- Density report
- Strength test certificate from NABL-accredited lab
- Product data sheet with declared mechanical properties
4. Formaldehyde Emission Test – Low/Zero VOC
- What is it?
Measures Volatile Organic Compounds (VOC) and formaldehyde emissions from the sheet. Necessary for health and green building compliance (LEED/GREEN PRO certified projects). - Testing Standard:
- EN 717-1 (Formaldehyde Release – Europe)
- ASTM D5116 (USA)
- JIS A 1460 (Japan)
- Safe Emission Values:
- E1 Class: ≤ 0.124 mg/m³ (low-emission)
- E0 Class: ~ 0.05 mg/m³ (nearly zero)
- Some sheets are formaldehyde-free
- ✅ Ensure Supplier Provides:
- VOC/Formaldehyde test report from SGS/Intertek/NABL lab
- Declare “E1/E0 certified” or “Zero VOC” on packaging or brochure
📄 How to Get These Reports?
You should request these directly from your manufacturer or distributor. Use this checklist:
- 🔲 NRC Lab Certificate (ASTM C423 or ISO 354)
- 🔲 Fire Rating Certificate (ASTM E84, EN 13501-1)
- 🔲 Density & Strength Data Sheet (ISO 845, ISO 1798)
- 🔲 VOC/Formaldehyde Certificate (EN 717-1 or ASTM D5116)
