Pressure Equipment Directive (PED) is een begrip binnen de industriële digitalisering en lasnormen & certificering.

Definitie

Pressure Equipment Directive (PED) is Europese richtlijn 2014/68/EU die de essential safety requirements stelt voor het ontwerp, fabricage en conformiteitsassessment van pressure equipment en assemblies. Het harmoniseert veiligheidsnormen binnen de EU en vereist CE-marking voor commercialisering van drukdragende apparatuur.

Kenmerken

  • Scope definition: Applies to pressure equipment with maximum allowable pressure > 0.5 bar
  • Category classification: Risk-based categorization (I, II, III, IV) determining conformity procedures
  • Essential safety requirements: Fundamental safety principles voor design, materials, manufacturing
  • Conformity assessment: Prescribed procedures including third-party certification
  • CE marking: Mandatory marking indicating compliance met directive requirements
  • Technical documentation: Required design calculations, material certificates, test records
  • Notified bodies: Authorized third-party organizations voor conformity assessment
  • Market surveillance: Member state enforcement en compliance monitoring
  • Harmonized standards: European standards providing presumption of conformity
