Workplace atmospheres. Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours - Performance requirements for apparatus used for general gas detection algolia-ignore BS EN 61966-9 on colour1 Scope This European Standard specifies the performance requirements for electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours in workplace atmospheres. This European Standard is applicable to apparatus used for general gas detection. EXAMPLE Safety warning and leak detection are examples of general gas detection.
