Application Summary AI generated
GB/T 20018-2005 specifies the beta backscatter method for measuring the thickness of metallic and non-metallic coatings on various substrates. It is applied in manufacturing and quality control settings, particularly for thin coatings (typically 0.1–100 μm) on small or irregularly shaped parts where other methods are impractical. This standard is used in industries such as electronics, automotive, and aerospace to ensure coating uniformity and compliance with thickness specifications.
