EN 589 details the technical requirements and testing protocols for automotive LPG, also known as low-pressure gas, which is designed for use in vehicles fitted with LPG-powered engines. LPG is a highly volatile hydrocarbon that is commonly stored at high pressure. Upon depressurization, it can produce substantial amounts of gas, capable of forming explosive mixtures with air within a concentration range of roughly 2% to 10% by volume. The standard encompasses the procedures for sampling, handling, and testing LPG. Potential ignition sources include open flames, unshielded electrical appliances, and static electricity. When in liquid form, LPG can cause frostbite-like injuries...

EN 14683 outlines the construction, design, performance criteria, and testing methods for medical face masks that aim to minimize the spread of infectious agents from healthcare personnel to patients during surgical operations and in other medical environments with comparable needs. A medical face mask that provides an adequate microbial barrier can also help decrease the release of infectious agents from the respiratory tract of asymptomatic individuals or patients exhibiting clinical symptoms. It is important to note that this document does not pertain to face masks designed solely for the personal protection of healthcare workers.

1.1 EN 50176 outlines the electrical specifications necessary for designing automatic electrostatic application systems intended for liquid coating materials that can ignite when atomized, operating within a temperature range of 5 °C to 40 °C. It addresses automatic electrostatic systems used for ignitable liquid coatings, where the overall conductivity of the system is restricted to a maximum of 50 nS/cm. With the implementation of additional safety measures, such as potential separation systems, these standards can also be applied to ignitable liquid coatings with a conductivity limit of up to 2,000 μS/cm. The document takes into account ignition risks associated with...
