General Information

Abstract

This European standard specifies detailed functional requirements for the commissioning, operation and maintenance of industrial gas installations operating above 0,5 bar and domestic or commercial gas installations above 5 bar. For non-industrial [domestic and commercial] gas installations up to 5 bar, EN 1775 applies.
This European standard also applies to gas installations up to 5 bar not within the scope of EN 1775 or other European standards, as well as to mixed installations [industrial and non-industrial].
The inlet connection to the appliance is normally the inlet isolation valve but can include the pipework downstream of this valve- if this pipework is not covered by the appliance standard, then this standard applies.
The requirements for design, materials, construction, inspection and testing of gas installations over 0,5 bar and domestic or commercial gas installations over 5 bar are given in part 1 (WI 00234026) of this standard.
In this standard the term 'gas' refers to combustible gases, which are gaseous at 15 °C and 1,013 mbar absolute pressure.  These gases, are commonly referred to as manufactured gas, natural gas or liquid petroleum gases (LPG). They are also referred to as first, second or third family gases (see table 1 of EN 437: 1993).
LPG storage tanks (including all ancillaries fitted directly to the tanks) are excluded see prEN 14570.  Also excluded are LPG installations and sections of LPG installations operating at vapour pressure.
In this standard, all pressures are gauge pressures unless otherwise stated.

Overview

prEN 15001-2 - Gas supply systems - Part 2: Detailed functional requirements for commissioning, operation and maintenance - provides functional requirements for the safe commissioning, operation and maintenance of gas installation pipework. The standard applies to industrial gas installations with operating pressures greater than 0,5 bar and to domestic or commercial installations with operating pressures greater than 5 bar. It also covers mixed installations and gas installations up to 5 bar not within the scope of EN 1775.

The term “gas” in this standard refers to combustible gases that are gaseous at 15 °C and 1,013 mbar (natural gas, manufactured gas, LPG families referenced in EN 437). LPG storage tanks and vapour‑pressure sections are excluded (see prEN 14570).

Key topics and technical requirements

prEN 15001-2 specifies detailed functional requirements rather than prescriptive designs. Key topics typically addressed include:

  • Commissioning procedures for newly installed or modified gas pipework, including verification of system readiness and functional checks.
  • Operational requirements covering safe use, monitoring, control, and normal/abnormal operating states.
  • Maintenance requirements for planned inspections, preventive maintenance and corrective actions to maintain system integrity.
  • Inlet connection scope - inlet isolation valve normally defines the appliance inlet; where downstream pipework is not covered by the appliance standard, prEN 15001-2 applies.
  • Safety and documentation expectations, including records of commissioning, maintenance history and competencies of personnel.
  • Applicability to mixed installations and installations not covered by EN 1775 for lower pressures.

Note: design, materials, construction, inspection and testing requirements for these pressure ranges are given in Part 1 (WI 00234026). prEN 15001-2 focuses on functional performance for safe lifecycle use.

Practical applications and users

Who uses prEN 15001-2:

  • Gas installation designers and engineering consultants
  • Commissioning engineers and installation contractors
  • Plant operators, facility managers and maintenance teams in industrial and commercial sites
  • Safety officers and compliance auditors
  • Regulatory bodies specifying requirements for high‑pressure gas systems

Typical use cases:

  • Commissioning of industrial gas distribution pipework (>0,5 bar)
  • Operation and maintenance programs for commercial gas systems (>5 bar)
  • Developing site procedures, maintenance schedules and competency requirements
  • Integrating appliance inlet pipework that falls outside appliance standards

Related standards

  • EN 15001-1 (Part 1) - design, materials, construction, inspection and testing
  • EN 1775 - non-industrial gas installations up to 5 bar
  • EN 437 - gas families and test conditions
  • prEN 14570 - LPG storage tanks (excluded from prEN 15001-2)

Using prEN 15001-2 ensures functional safety and consistent lifecycle management for higher‑pressure gas supply systems in industrial and non‑domestic environments.
