EN 1440:2016/prA1:2017

Overview

EN 1440:2016/prA1:2017 is a European Standard developed by CEN (European Committee for Standardization) focusing on the periodic inspection and testing of transportable, refillable traditional welded and brazed steel Liquefied Petroleum Gas (LPG) cylinders. The standard applies to cylinders with a water capacity ranging from 0.5 liters up to and including 150 liters. It covers LPG cylinders manufactured according to EN 1442, EN 12807, EN 13322-1, or equivalent standards, including those complying with RID/ADR regulations (such as pi marked cylinders), but excludes cylinders permanently installed in vehicles.

This standard is critical for ensuring the continued safety, reliability, and compliance of LPG cylinders in use across transportation and refill applications throughout Europe and other adopting countries.

Key Topics

• Scope and Applicability
  Applies to welded and brazed steel LPG cylinders of specified minimum wall thickness designed under recognized European or equivalent standards.

• Periodic Inspection Procedures
  Details the step-by-step verification, testing, and inspection protocols for LPG cylinders, including pressure testing and leak detection.

• Reconditioning and Minor Repairs
  Defines terms such as minor repair (cleaning and simple component replacement) and reconditioning (major repairs including welding or de-denting) performed by qualified personnel under approved procedures.

• Test Pressure Requirements
  Specifies that test pressure must be maintained for a minimum of 15 seconds during inspection to detect leaks or cylinder deformation.

• Record Keeping
  Mandates maintaining records for rejected cylinders for at least 10 years, enhancing traceability and safety auditing.

• Compliance with RID/ADR
  Acknowledges that mandatory regulations under RID/ADR take precedence over EN 1440 requirements when applicable, ensuring regulatory harmony.

• Amendments and Updates
  Incorporates clarifications and additions regarding inspection intervals, responsibilities, and testing details to keep up with evolving safety practices.

Applications

• Transportable LPG Cylinder Maintenance
  Serving gas distributors, cylinder refurbishment companies, and safety inspectors, the standard ensures LPG cylinders remain fit for safe use during transport and refilling cycles.

• Safety Assurance
  Helps prevent accidents by ensuring cylinders are regularly inspected for leaks, material failures, or permanent distortions that could compromise integrity.

• Regulatory Compliance
  Aligns maintenance schedules and inspection procedures with European and national safety laws, streamlining compliance for manufacturers and service providers.

• Quality Control
  Supports LPG equipment manufacturers and service operatives in establishing standardized periodic inspection regimes, boosting product safety and customer confidence.

Related Standards

• EN 1442: Design and construction requirements for LPG cylinders.
• EN 12807: Additional technical specifications governing welded LPG cylinders.
• EN 13322-1: Specifications for welded LPG cylinders including inspection and testing methods.
• RID/ADR Regulations: International regulations for the transport of dangerous goods by rail (RID) and road (ADR), which include specific rules on LPG cylinder packaging and inspection. These regulations supersede parts of EN 1440 when applicable.

Practical Value

Implementing EN 1440:2016/prA1:2017 enables companies handling LPG cylinders to:

• Guarantee the structural integrity and safety of refillable LPG cylinders used in transportation and domestic markets.
• Streamline inspection processes with clear, measurable parameters and intervals.
• Ensure legal compliance with both European standards and transport regulations (RID/ADR).
• Enhance documentation practices for audit readiness and traceability of cylinder service history.

Using EN 1440 facilitates safer LPG cylinder operations, reducing risks associated with gas leaks or cylinder failures and promoting industry best practices for LPG equipment maintenance across Europe.
