IS 16010:2012 is the Indian Standard (BIS) for mineral wool boards/slabs for acoustic insulation - specification. This standard specifies the requirements for mineral wool (rock and slag wool) boards and slabs intended for use as acoustic insulation. It covers material composition, dimensions, physical properties such as density, thermal conductivity, and fire performance, with a primary focus on the sound absorption coefficient (NRC).
Specifies requirements for mineral wool boards and slabs used for acoustic insulation.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Density Range (Typical) | Typically 40-150 kg/m³ for boards and slabs for acoustic applications. | EN 13162 allows a wide range of declared densities, typically 20-200 kg/m³, with specific declared density levels (e.g., DS(T) class). ASTM C612 specifies density for Types, e.g., Type I (48-96 kg/m³) and Type II (96-160 kg/m³). | EN 13162:2012, ASTM C612/C612M-21 |
| Thickness Tolerance | Typically ±5 mm for nominal thickness. | EN 13162 specifies thickness tolerance classes (T), e.g., T5 (±5 mm) for thicker products, T3 (±3 mm) for thinner ones. ASTM C612 allows ±4.8 mm for thicknesses up to 50 mm. | EN 13162:2012, ASTM C612/C612M-21 |
| Reaction to Fire | Shall be declared, typically Non-combustible (as per IS 3808 / IS 10810 Pt 57). | Products conforming to EN 13162 declare Euroclass A1 or A2-s1,d0 as per EN 13501-1. ASTM C612 refers to ASTM E84 for surface burning characteristics (e.g., Flame Spread Index < 25, Smoke Developed Index < 50 for non-combustible). | EN 13162:2012 (referring to EN 13501-1), ASTM C612/C612M-21 (referring to ASTM E84) |
| Water Absorption (Short Term) | Not more than 1.0 kg/m² for boards (Class A) or 3.0 kg/m² for slabs (Class B) by partial immersion. | EN 13162 specifies WS (Water absorption short term) class, with typical requirements like WS < 1.0 kg/m². ASTM C612 has no direct comparable 'short-term partial immersion' requirement for boards. | EN 13162:2012 |
| Sound Absorption Coefficient (αw) | Requires declaration of weighted sound absorption coefficient (αw) as per ISO 11654, with typical values for boards ranging from 0.40 to 1.00 depending on thickness and density. | ISO 11654:1999 provides the method for deriving αw and absorption classes (A-E) from ISO 354 measurements. Product standards like EN 13162 and ASTM C612 mandate the declaration of acoustic properties for products used in acoustic applications, but do not specify mandatory αw values in their core text. Typical high-performance MW products achieve αw from 0.65 to 1.00. | ISO 11654:1999, ISO 354:2003, EN 13162:2012 |
| Compressive Strength | Shall be declared by manufacturer, typical for non-load bearing applications (e.g., > 10 kPa at 10% compression). | EN 13162 defines compressive stress (CS(Y)) at 10% deformation, with various classes (e.g., CS(10) ≥ 10 kPa). ASTM C612 specifies compressive strength in Types, e.g., Type I > 50 kPa, Type II > 100 kPa. | EN 13162:2012, ASTM C612/C612M-21 |
