Nor1517 Tapping Machine

Standard tapping machine for floor impact sound testing according to ISO 10140 and ISO 16283-2.

Overview

The Nor1517 is a precision-engineered standard tapping machine designed for floor impact sound insulation measurements in both laboratory and field environments. Fully compliant with ISO 10140-5 and ISO 16283-2, it generates standardized impact sounds using five precision-machined cylindrical hammers, each weighing 500 g, falling from a controlled height of 40 mm at a rate of 10 impacts per second…

Frequently Asked Questions

  • What is a tapping machine used for in floor impact sound testing?
    A tapping machine generates standardized impact sounds on a floor surface to measure the impact sound insulation performance of floor constructions. The Nor1517 produces precisely controlled impacts according to ISO 10140-5 requirements, enabling accurate determination of impact sound pressure levels (Ln and L'nT) used to calculate single-number ratings like Ln,w and L'nT,w.
  • Does the Nor1517 meet ISO 10140-5 tapping machine requirements?
    Yes, the Nor1517 is fully compliant with ISO 10140-5 requirements for standard tapping machines. It features five 500 g cylindrical hammers falling from a height of 40 mm at a rate of 10 impacts per second, meeting all mechanical parameters specified in the standard for both laboratory and field measurements.
  • Can the Nor1517 be used for field measurements according to ISO 16283-2?
    Yes, the Nor1517 is designed for both laboratory measurements per ISO 10140-3 and field measurements per ISO 16283-2. Its lightweight portable design (approx. 10 kg) makes it easy to transport to construction sites for in-situ floor impact sound testing.
