What is ISO/TS 16976‑4 - Physiologically based limits for breathing resistance in respiratory protective devices (RPD) about ?
ISO/TS 16976 discusses respiratory devices (RPD) human factors. ISO/TS 16976‑4 is an international standard that provides physiologically based limits for breathing resistance in respiratory protective devices. ISO/TS 16976‑4 is the fourth part of a multi-series on respiratory protective devices that specifies how to calculate the work performed by a person’s respiratory muscles with and without the external respiratory impediments that are imposed by RPD of all kinds, except diving equipment. ISO/TS 16976‑4 describes how much additional impediment people can tolerate and contains values that can be used to judge the acceptability of an RPD. Note: These calculations are explained in some textbooks on respiratory physiology (in the absence of an RPD), but most omit them or are incomplete in their explanations.
