Overview
EN 12327:2012 - published by CEN (Technical Committee CEN/TC 234) - sets out the functional requirements and common principles for pressure testing, commissioning and decommissioning of gas infrastructure. It applies to transmission and distribution pipeline systems (excluding installation pipework covered by EN 1775) and is intended to be used together with more detailed national standards and codes of practice.
Key topics and technical requirements
- Scope and application
- Applies to strength testing, tightness testing and combined testing of gas infrastructure components.
- Does not specify test pressure levels, test durations or detailed acceptance criteria - these are determined by national legislation or pipeline operators.
- Test media and methods
- Recognises hydrostatic testing (water), pneumatic testing (air or inert gas) and testing with gas at operating pressure.
- Allows a preliminary low‑pressure air/inert gas test (max 0.5 bar) before hydrostatic testing; this does not replace the tightness test.
- Pressure relationships
- Strength/combined tests: test pressure shall be higher than the system’s Maximum Incidental Pressure (MIP).
- Tightness tests: typically at or above Operating Pressure (OP) when no prior strength test has been done.
- Measurement, instrumentation and recording
- Pressure measurement equipment minimum accuracy class 0,6; recording devices may be class 1.
- Pressure gauges should comply with EN 837-1/2/3; instruments require valid calibration certificates.
- Temperature effects must be considered; temperature instruments should have minimum scale reading of 1 °C.
- Procedures, safety and documentation
- A written procedure must specify: test method, test pressure, period, test medium, acceptance criteria, allowable pressure/volume variation, leak detection, release/disposal of test media and water disposal.
- Tests must be performed by an authorized/competent person. Precautions against over‑pressure, movement of unrestrained pipework and safety of personnel/environment are required.
- Test report and commissioning or decommissioning records are required.
- Annexes
- Annex A: purging criteria (informative)
- Annex B: list of related CEN/TC 234 functional standards
Practical applications and users
Who uses EN 12327:2012:
- Pipeline operators and system owners
- Commissioning and testing engineers
- Contractors performing pressure tests and purging
- Competent authorities and inspectors
- Health, safety and environmental teams
Typical use cases:
- Commissioning new pipeline sections and stations
- Verifying mechanical strength and leak tightness after construction or repair
- Safe decommissioning and purging of gas-filled equipment
- Preparing test procedures and compliance documentation in line with national rules
Related standards
- EN 1775 - installation pipework (not covered by EN 12327)
- EN 837-1 / EN 837-2 / EN 837-3 - pressure gauge standards

EN 12327:2012 is a European Standard that provides guidelines for pressure testing, commissioning, and decommissioning of gas infrastructures. The standard applies to gas infrastructures covered by the Technical Committee CEN/TC 234's functional European Standards. It does not cover installation pipework, which is addressed by EN 1775. The standard includes procedures for strength testing, tightness testing, and combined testing, but does not specify test pressure levels, test periods, or acceptance criteria. National legislation or pipeline operators may require additional measures or different testing methods. Users should be aware that more detailed national standards and codes of practice may exist in the CEN member countries. In case of conflicts between national legislation and the requirements of this European Standard, the national legislation takes precedence. CEN/TR 13737 provides clarification on applicable legislations/regulations in member states, more restrictive national requirements if applicable, and a national contact point for up-to-date information.

It specifically applies to gas infrastructures covered by the Technical Committee CEN/TC 234. The standard does not include installation pipework, which is covered by EN 1775. The procedures described in the standard are for strength testing, tightness testing, and combined testing. However, it does not specify test pressure levels, test periods, or acceptance criteria. The individual member countries may have additional requirements or alternative testing methods based on their legislation or the discretion of the pipeline operator. It is important for users of this standard to be aware that more detailed national standards or codes of practice may exist in the CEN member countries, and those should be considered alongside this European Standard. If conflicts arise between the requirements of this European Standard and more restrictive national legislation/regulation, the national legislation/regulation should take precedence, as explained in CEN/TR 13737. CEN/TR 13737 provides clarification of applicable legislations/regulations in member states, more restrictive national requirements if applicable, and a national contact point for up-to-date information.
記事のタイトル: EN 12327:2012 - ガスインフラストラクチャー - 圧力試験、起動および解体手順 - 機能要件 記事の内容: このヨーロッパ標準では、技術委員会CEN/TC 234の対象となるガスインフラストラクチャーの圧力試験、起動、および解体の共通原則について説明しています。これらは、加盟国の詳細な実施規範やオペレーティングマニュアルから抽出されました。このヨーロッパ標準は、EN 1775で対象となる取り付け配管を含まず、強度試験、気密試験、および複合試験に適用される手順を指定しています。ただし、試験圧力レベル、試験期間、および受け入れ基準はこのヨーロッパ標準ではカバーされていません。個々の加盟国の法律やパイプラインオペレーターの裁量により、追加の措置や異なる試験、起動、または解体方法が必要とされる場合があります。このヨーロッパ標準は、ガスインフラストラクチャーに対する共通の基本原則を指定しています。このヨーロッパ標準の利用者は、CEN加盟国でより詳細な国内規格や実施規範が存在する可能性があることを認識する必要があります。このヨーロッパ標準の要件とより制約のある国内法令/規制との間に衝突がある場合は、CEN/TR 13737に示されているように、国内法令/規制が優先されるべきです。CEN/TR 13737では、加盟国で適用可能な法令/規制の明確化、必要に応じてより制約のある国内要件、最新の情報のための国内連絡先を提供しています。
