The tasting glass consists of a cup (an “elongated egg”) supported by a stem resting on a base

This means that voice alarm loudspeakers need to achieve a minimum acoustical performance

The British Standard

The extinguishing agent normally arrives at the nozzle in two-phase flow form (liquid-gaseous mixture)

Sanitary tapware. Low pressure mechanical mixing valves. General technical specification Ingestion-build-68772 with fixed top (see figure1 Scope This European Standard specifies requirements for low hydraulic resistance mechanical mixing valves suitable for use in low pressure water supply systems as described in informative annex C. This European Standard specifies: the dimensional, leaktightness, mechanical and hydraulic performance, mechanical endurance characteristics with which low pressure mechanical mixing valves shall comply; the procedure for testing these characteristics.
