- Structure-based: Thermal insulation/Heated or Cold floors (R), Protection against unevenness (PC), Protection against moisture (SD)
- Use-based: Protection against loads and usage (CS: Temporary exposure caused by loads, DL: Dynamic exposure caused by walking, CC: Long-term exposure caused by static loads), Protection against falling objects (RLB)
- Acoustics-based: Impact sound insulation (IS), Reflected walking sound (RWS)
Impact sound – EN ISO 10140-3 and EN ISO 717-2
- Floor stimulation via so-called standard tapping machine
- Noise measurement in the room below (by contrast with walking noise testings)
- Result: evaluated impact noise insulation (unit: dB)
Reflected Walking sound – IHD Works Standard 431
- Excitation of noise emissions by walking on a floor with ladies’ high-heeled shoes
- Result: absolute and relative changing of the psycho-acoustic measurand “loudness” of the emitted noise (unit: Sone or %)
