[Current]Protective clothing against heat and flame, Part 2: Skin burn injury prediction - Calculation requirements and test cases
AS/NZS ISO 13506.2:2025 identically adopts ISO 13506-2:2024 which provides technical details for calculating predicted burn injury to human skin when its surface is subject to a varying heat flux, such as may occur due to energy transmitted through and by a garment or protective clothing ensemble exposed to flames
