The total thickness of the thin film layers should be 100 times less than the thickness of a supporting substrate (typically a silicon wafer piece)

provided that the dimensions of any inhomogeneity in close proximity to the heat flow meter (HFM) is much smaller than its lateral dimensions and are not thermal bridges which can be detected by infrared thermography (see 6

Textiles. Measurement of water vapour permeability of textiles for the purpose of quality control Ingestion-build-109673 The total thickness of the1 Scope This document describes a comparatively simple method for testing the water vapour permeability of textiles that will provide the manufacturer with a clearly recognized method for quality control within the plant. The simple test method described in this document is not applicable for classifying the water vapour resistance of textiles against values relating to physiological effects specified in product standards, and particularly not those
