ISO 4413 and ISO 4414: Safety Rules for Hydraulic and Pneumatic Machinery
What ISO 4413:2010 and ISO 4414:2010 cover for hydraulic and pneumatic machinery, how they sit beside ISO 13849-1, and what US practice adds.
ISO 13849-1:2023 for Hydraulic and Pneumatic Safety Functions
How ISO 13849-1:2023 applies to hydraulic and pneumatic safety functions: valve MTTFD and B10D data, cyclic switching, monitoring, validation, and lockout.
Stored Energy and LOTO: Accumulators, Trapped Pressure, and Gravity Loads
Stored hydraulic and pneumatic energy at lockout: what OSHA 1910.147 requires, accumulator discharge, trapped line pressure, residual air, and blocking loads.
Pneumatics in Cold, Dusty Mills: Air Preparation and Freezing
Compressed air for cold, dusty mills: pressure dew point, dryers below freezing, ISO 8573-1 classes, filters, heated drains, and OSHA's 30 psi cleaning rule.
