PPE test heads for standard testing, research, and quality control<\/strong><\/h2>

Respiratory protection test heads are specialized test bodies<\/strong> developed for the standards-compliant evaluation of respiratory protection systems<\/strong>. They serve as a standardized interface<\/strong> onto which respiratory interfaces such as masks, hoods, helmets, or protective suits<\/strong> are mounted. This enables precise, reproducible testing<\/strong> in accordance with the requirements defined in the relevant product standards.<\/p>

Via integrated connection ports<\/strong>, the test heads can be connected to breathing machines, lung simulators, or mask testing devices<\/strong>. This creates realistic test conditions<\/strong> that allow for reliable assessment of leak tightness, breathing resistance, and other safety-critical parameters<\/strong>.<\/p>

Two types of test heads are distinguished:<\/strong><\/p>

\u2022 Sheffield Test Head: <\/strong>A standardized test head for respiratory protective devices<\/strong>, widely used across Europe. It represents a single, uniform head size<\/strong> and is used as a reference for testing according to European standards<\/strong>.<\/p>

\u2022 ISO Test Head acc. to ISO 16900-5: <\/strong>A standardized test head system<\/strong> specifically designed for testing respiratory protective equipment. Unlike the Sheffield test head\u2014which represents only one standard size<\/strong>\u2014the ISO standard defines a set of five different head sizes<\/strong> based on real anthropometric data of the global population<\/strong>. Manufacturers are required to test their respiratory protection products across all relevant sizes<\/strong> to ensure full standards compliance<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

                The test heads can be directly connected to mask testing devices<\/strong>, enabling leak tightness testing of full-face masks acc. to EN 136<\/strong>. This procedure ensures that the respiratory protection system seals reliably<\/strong> and that no external air enters the mask through leaks<\/strong>.<\/p>
