Nor850 Building Acoustics (ISO 10140)

The Nor850 Building Acoustics ISO 10140 module is a specialized add-on for the Nor850 Reporting Software platform, designed for accredited testing laboratories performing standardized sound insulation measurements of building elements under controlled laboratory conditions. The module covers ISO 10140 Parts 2, 3, and 4 for airborne sound insulation, impact sound insulation, and specific measurement procedures respectively. The software calculates the sound reduction index (R) for airborne sound insulation and normalized impact sound pressure level (Ln) for impact sound insulation of building elements tested in standardized laboratory facilities. Weighted single-number ratings Rw and Ln,w are computed per ISO 717 with spectrum adaptation terms C and Ctr. Measurement uncertainty calculations per ISO 12999 and GUM principles are included to meet ISO 17025 accreditation requirements. Laboratory testing per ISO 10140 provides the reference data used by architects and engineers to specify building element performance in construction projects. Test reports generated by this module document the sound insulation properties of walls, floors, doors, windows, and other building elements with the precision and traceability required for product certification, manufacturer data sheets, and building code compliance verification. For accredited testing laboratories across the GCC and internationally, this module ensures that report documentation meets the quality and completeness requirements expected by accreditation bodies, certification organizations, and building product manufacturers. The module complements the ISO 16283 field testing module for organizations performing both laboratory and field building acoustics testing.
