#industrial standards

• Mechanical fit — The structural, dimensional, and functional relationship established following the assembly of two complementary parts (an encompassing one called a bore and an encompassed one called a shaft) that share the same nominal dimensions; by extension, the state of clearance or interference resulting from the actual difference in their dimensions prior to mounting. This micro-precise phenomenon is governed by rigorous standardized tolerances, determining exactly whether the components will move freely relative to one another or remain rigidly locked to transmit large mechanical forces within an industrial assembly.
• Fire-protection — Utilized for protection against fires or for extinguishing them; relating to safety systems, equipment, or protocols designed to counter fire outbreaks. In a structural sense, it qualifies automatic detection installations, doors resistant to extreme temperatures, or emergency evacuation plans.
• Anti-technical — Contrary to established technical standards, machinery operating rules, or industrial safety and efficiency specifications; opposing technical precision or spirit. It applies to incorrect procedures, faulty execution in engineering or construction, or a blatant lack of skill and knowledge in operating mechanical and technological systems, resulting in equipment degradation or the disruption of production processes.
• AZP — A technical acronym used to designate various structural concepts depending on the field, such as 'Low-Noise Power Supply' in electronics, 'Primary Flight Instrumentation' in aviation, or specific biochemical indicators in medical laboratories.
