In clothing, MVTR as a measure of breathability has contributed to greater comfort for wearers of clothing for outdoor activity. The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings.
ISO 22000 is the most popular voluntary food safety international standard in the food industry with 51,535 total number of sites (as per the ISO Survey 2022).The ISO 22000 family are international voluntary consensus standards which align to Good Standardization Practices (GSP) [3] and the World Trade Organization (WTO) Principles for the Development of International Standards.

Water vapor transmission rate also called moisture vapor transmission rate (MVTR) is a method of testing or measuring the permeability for vapor barriers. ASTM F2298 – 03 (test for clothing materials such as protective clothing, laminates, and membranes) a similar test by Japanese Standards Association is JSA – JIS L 1099. [119]
Chemical: Hydrophilic (water loving) / non-porous lamination or coating move moisture by chemical diffusion. The water molecule is positively charged and the hydrophilic PU is negatively charged, attracting the water through the intermolecular gaps of the PU. Because the ionic bond is relatively weak, the water then gets pushed through the gaps ...
A food safety hazard is any biological, chemical, or physical property that may cause a food to be unsafe for human consumption. Identify critical control points A critical control point (CCP) is a point, step, or procedure in a food manufacturing process at which control can be applied and, as a result, a food safety hazard can be prevented ...
Personal hygiene, hand washing, illness, and protective clothing. Food safety standards and requirements are set out at the national level in the Food Standards Code, and brought into force in each state and territory by state-based Acts and Regulations. Legislation means that people responsible for selling or serving unsafe food may be liable ...
Drop of water on 100% polyester textile. Waterproof/breathable fabrics resist liquid water passing through, but allow water vapour to pass through. Their ability to block out rain and snow while allowing vapour from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing, tents, and other applications.
Food contact material pictogram (left) on a plastic food container in Hong Kong. Food contact materials or food contacting substances (FCS) [1] [2] are materials that are intended to be in contact with food. These can be things that are quite obvious like a glass or a can for soft drinks as well as machinery in a food factory or a coffee machine.
