This document specifies the functional requirements relevant for design, materials, construction, testing, operation and maintenance of gas pressure control stations to ensure their reliability in terms of safety of the station itself and the downstream system and continuity of service.
This document is applicable for gas pressure control stations which are part of gas transmission or distribution systems for hydrogen, and hydrogen rich, and methane rich gases. Additional requirements in the case of gases heavier than air and/or toxic or corrosive gases are not covered by this document.
This document does not apply to gas pressure control stations in operation prior to the publication of this document. However, Annex D of this document can be used as guidance for the evaluation of stations in operation prior to the publication of this document, regarding the change of the type of gas, e.g. repurposing for the use with hydrogen.
The stations covered by this document have a maximum upstream operating pressure, which does not exceed 100 bar. For higher maximum upstream operating pressures, this document can be used as a guideline.
If the inlet pipework of the station is a service line and the maximum upstream operating pressure does not exceed 16 bar and the design flow rate is equal to 2000 kW based on the gross calorific value or less, EN 12279 applies.
This document contains the basic system requirements for gas pressure control stations. Requirements for individual components (valves, regulators, safety devices, pipes, etc.) or installation of the components are contained in the appropriate European Standards.
NOTE For combined control and measuring stations, the additional requirements of EN 1776 can apply.
The requirements in this document do not apply to the design and construction of auxiliary facilities such as sampling, calorimetering, odorization systems and density measuring. These facilities are covered by the appropriate European Standards, where existing, or applicable national standards.
The requirements of this document are based on good gas engineering practice under conditions normally encountered in the gas industry. Requirements for unusual conditions cannot be specifically provided for, nor are all engineering and construction details prescribed.
The objective of this document is to ensure the safe operation of such stations. This does not, however, relieve all concerned of the responsibility for taking the necessary care and applying effective quality and safety management during the design, construction, operation and maintenance.

This document specifies a method for determining the sound power level of a fan. This document is applicable to fans as defined in ISO 13349-1. The applicability of this document is limited to the determination of airborne sound emission for the specified set-ups. Vibration is not measured, nor is the sensitivity of airborne sound emission to vibration effects determined. The sizes of fan which can be tested in accordance with this document are limited only by the practical aspects of the test set-up. Dimensional limitations, test fan dimensions, and air performance will control the room size, power and mounting requirements for the test fan. NOTE Small fans can be tested according to this document or to ISO 10302-1, according to usage. The test arrangements in this document establish the laboratory conditions necessary for a successful test. Rarely will it be possible to meet these requirements in situ and this document is not intended for field measurements. NOTE Intending users are reminded that, in these situations, there can be additional acoustic system effects where inlet and outlet conditions at the fan are less than ideal. The enveloping surface methods can be used for the determination of open inlet and/or open outlet sound power level of fans for the standardized installation categories given in 4.1. An estimation (with increased uncertainty) of ducted sound power for fans too small, or otherwise inconvenient, for testing by the in-duct method described in ISO 5136 can also be obtained by the addition of end reflection corrections (see ISO 13347-1:2025, Annex C).

This document focuses on recommending condition monitoring (CM) techniques for detecting and diagnosing developing machine faults associated with the most common potential failure modes in reciprocating compressors. This document is intended to set out a reliable and effective CM approach for reciprocating compressors, to create a mutual understanding of the criteria for successful reciprocating compressor CM and to foster cooperation between the various application stakeholders, for use by end-users, contractors, consultants, service providers, machine and part manufacturers and instrument suppliers, as the reciprocating compressor design, its operation and maintenance regime can be very different from one application to the next, it is important to highlight that condition monitoring and diagnostics method described in this document is reference guidelines and non-mandatory information, and To make this standard more effective, it is required to actively share the operation and condition data of the reciprocating compressor among the relevant parties. Some of the reciprocating compressor types covered by the requirements of this document include: slow (under 600 r/min) and moderate speed (600 r/min to 1 000 r/min) machines manufactured and procured in accordance with the requirements of API STD 618; high-speed and pre-packaged machines (over 1 000 r/min) on a skid that are manufactured and procured in accordance with the requirements of ISO 13631 or API SPEC 11P; hyper compressors used for secondary ethylene compression in low density polyethylene (LDPE) production; lubricated and non-lubricated machines; water-cooled and gas-cooled machines; horizontal, vertical V-type, L-type and W-type machines; horizontal, vertical machines with piston rings and those with labyrinth seal pistons (vertical machines only); single-acting and double acting machines; machines with a tandem cylinder configuration; single and multi-stage compression machines; machines with and without capacity control; ring, poppet, reed and plate valve type machines; machines mounted on flexible and rigid structures; machines driven by electric motors, gas and diesel engines, turbines (with or without a gearbox) all with a flexible or rigid coupling; tintegral gas-engine-driven machines (engine portion out of scope); offshore applications (e.g. platforms, FPSOs (floating production storage and offloading), FLNGs (floating liquified natural gas), FPU (offshore foating production unit) and fixed installations). This document focuses on the compressor itself (cylinders, distance pieces, crosshead, frame and all internal parts) and not on the prime mover or the external systems (e.g. piping, scrubbers, pulsation vessels, and pulsation control devices). Only brief mention is made of monitoring the foundation, skid and pedestal. The scope does not include requirements for monitoring the auxiliary systems (e.g. for lubrication, cylinder cooling, intercoolers and gas purging), but process parameters from these systems are often monitored. The scope does not cover installation analyses of systems either, (e.g. pulsation and mechanical response and thermal analysis of the piping). This document covers online (permanently installed) and portable instrument CM and diagnostic techniques for operating reciprocating compressors. Machine testing, which is only done during shutdown, although very important, is not part of the scope of this document, nor is the one-time acceptance and performance testing.
