prEN ISO 18393-1 Thermal insulation products - Determination of ageing by settlement - Part 1: Blown loose fill insulation for ventilated attics simulating humidity and temperature cycling (ISO/DIS 18393-1:2022)
This document specifies a test method for the determination of settlement of blown loose-fill insulation applied in for ventilated attics. This test method measures the ageing related to temperature and moisture cycling; However, there may be other factors, impact, seismic, vibration of any kind which may influence a change in thickness.
