Pressure equipment - Part 6: Structure and content of operating instructions

This part six of EN 764 is a Technical Report and as such is a generic document that identifies requirements for operating instructions which accompany the pressure equipment when it is placed on the market. It only provides general statements and thus does not claim to give presumption of conformity to the essential safety requirements of the Pressure Equipment Directive (PED).
Operating instructions contain the necessary safety information covering installation including assembling, putting into service and maintenance. For specific items of pressure equipment or assemblies, more detailed requirements on the content of operating instructions can be found in specific standards such as EN 13445 Unfired pressure vessels, EN 13480 Industrial piping, EN 12952 Water-tube boilers and auxiliary installations, or EN 12953 Shell boilers.

Druckgeräte - Teil 6: Aufbau und Inhalt einer Betriebsanleitung

Der vorliegende Teil 6 der EN 764 ist ein Technischer Bericht und somit ein allgemeines Dokument, das Anforderungen an die Betriebsanleitung festlegt, die einem Druckgerät beigefügt wird, wenn dieses in Verkehr gebracht wird. Er enthält ausschließlich allgemeine Angaben und beansprucht somit nicht die Annahme der Konformität mit den grundlegenden Sicherheitsanforderungen der Druckgeräterichtlinie 97/23/EG (DGR).
Die Betriebsanleitung enthält die erforderlichen sicherheitsbezogenen Angaben für die Installation, einschließ-lich Zusammenbau, Inbetriebnahme und Instandhaltung. Detailliertere Anforderungen an den Inhalt einer Betriebsanleitung für bestimmte Druckgeräte oder Baugruppen sind speziellen Normenreihen, wie z. B. EN 13445 Unbefeuerte Druckbehälter, EN 13480 Metallische industrielle Rohrleitungen, EN 12952 Wasserrohrkessel und Anlagenkomponenten oder EN 12953 Großwasserraumkessel zu entnehmen.

Equipements sous pression - Partie 6: Structure et contenu des instructions de service

Cette partie six de l’EN 764 est un Rapport Technique, et en tant que tel constitue un document générique qui identifie les exigences relatives aux instructions de service qui accompagnent les équipements sous pression lorsqu’ils sont mis sur le marché. Il fournit des indications générales et donc ne peut pas prétendre à donner présomption de conformité aux exigences essentielles de sécurité de la Directive Equipement sous pression 97/23/CE (DESP).
Les instructions de service comprennent les informations de sécurité nécessaires à l’installation, notamment l’assemblage, la mise en service et la maintenance. Pour des équipements sous pression ou des ensembles spécifiques, des exigences plus détaillées sur le contenu des instructions de service peuvent figurer dans des séries de normes particulières, telles que l’EN 13445 « Récipients à pression non soumis à la flamme », l’EN 13480 « Tuyauteries industrielles », l’EN 12952 « Chaudières à tubes d’eau et installations auxiliaires » ou l’EN 12953 « Chaudières à tubes de fumée ».

Tlačna oprema - 6. del: Oblika in vsebina navodil za obratovanje

Ta šesti del standarda EN 764 je tehnično poročilo in kot tako generičen dokument, ki identificira zahteve za navodila za obratovanje, ki so priložena tlačni opremi, ko je ta dana na trg. Ponuja samo splošne izjave in tako ne daje zagotovil o skladnosti z osnovnimi varnostnimi zahtevami z Direktivo 97/23/ES o tlačni opremi (PED). Navodila za obratovanje vsebujejo obvezne varnostne informacije o namestitvi, vključno s sestavljanjem, delovanjem in vzdrževanjem. Za določene proizvode tlačne opreme ali sklopov je več podrobnih zahtev o vsebini navodil za obratovanje na voljo v določenih serijah standardov, kot so EN 13445 »Neogrevane tlačne posode«, EN 13480 »Industrijski cevovodi«, EN 12952 »Vodocevni kotli in pomožne napeljave« ali EN 12953 »Mnogovodni kotli«.

Overview

SIST-TP CEN/TR 764-6:2012 is a technical report developed by CEN/TC 54 that outlines the structure and content of operating instructions for pressure equipment placed on the market within Europe. This part six of the EN 764 series provides generic guidelines for manufacturers to create comprehensive manuals that accompany pressure equipment, including necessary safety information for installation, operation, maintenance, and disposal.

While it offers general requirements, the report does not claim to ensure conformity with the essential safety requirements defined in the Pressure Equipment Directive (PED) 97/23/EC. Instead, it serves as a foundational reference for operating instructions, facilitating compliance with legal and safety expectations.

Key Topics

• Scope and Purpose
  The document emphasizes the need to address all foreseeable hazards that may arise during the mounting, commissioning, use, and maintenance of pressure equipment. It includes information critical to safe operation but defers highly specific requirements to other standards such as EN 13445 (Unfired Pressure Vessels) or EN 13480 (Industrial Piping).

• Hazard Analysis
  Essential to the operating instructions is a detailed hazard analysis identifying potential failure modes under expected operating conditions. Examples include exceeding pressure or temperature limits, corrosion issues, improper handling of valves, and failure of safety devices.

• Mandatory Data Plate Information
  The instructions must highlight key information from the pressure equipment’s data plate, such as manufacturer identification, manufacturing year, maximum allowable pressure and temperature, volume, test pressure, safety device settings, and fluid type.

• Content of Operating Instructions
  Operating instructions must comprehensively cover:

  • Installation guidelines (transport, storage, assembly)
  • Procedures for safe commissioning and putting into service
  • Detailed guidance on safe operation, including warnings about residual or residual hazards
  • Maintenance and inspection intervals to account for fatigue, creep, corrosion, and wear
  • Handling of emergency situations
  • Documentation about spare parts and replacement components
  • Disposal practices addressing safety and environmental concerns

• Language and Documentation
  Operating instructions must be provided in a written form or electronic database and furnished in the official language(s) of the member state where the equipment is marketed.

Applications

SIST-TP CEN/TR 764-6:2012 targets manufacturers, distributors, and end-users of various types of pressure equipment such as industrial piping, pressure vessels, boilers, and gas cylinders. It supports:

• Manufacturers in developing standardized, clear, and comprehensive operating manuals that align with EU regulations and safety best practices.
• Operators and maintenance personnel by providing vital information to ensure safe installation, use, routine inspection, and maintenance of pressure equipment.
• Safety engineers and compliance officers responsible for risk assessment and hazard mitigation.
• Project managers and clients involved in specifying operational constraints and safety requirements for pressure equipment.

By adhering to the guidelines, stakeholders reduce the risk of accidents, improper use, and equipment failure, thereby enhancing workplace safety and equipment reliability.

Related Standards

CEN/TR 764-6 references and complements several other key standards which provide detailed technical requirements for specific types of pressure equipment:

• EN 13445 – Unfired Pressure Vessels: Includes detailed requirements for operating instructions relevant to non-heated vessels.
• EN 13480 – Industrial Piping: Specifies piping systems including content for operation and maintenance manuals.
• EN 12952 – Water-Tube Boilers and Auxiliary Installations: Technical specifics for boiler operation documents.
• EN 12953 – Shell Boilers: Guidance on operational safety and documentation for shell boilers.
• PED 97/23/EC – Pressure Equipment Directive: European legislation outlining essential safety requirements and conformity procedures.

Manufacturers and users should consult these standards alongside SIST-TP CEN/TR 764-6:2012 to ensure comprehensive hazard coverage, conformity, and enhanced operational safety.

This part six of EN 764 is a Technical Report and as such is a generic document that identifies requirements
for operating instructions which accompany the pressure equipment when it is placed on the market. It only
provides general statements and thus does not claim to give presumption of conformity to the essential safety
requirements of the Pressure Equipment Directive (PED).
Operating instructions contain the necessary safety information covering installation including assembling,
putting into service and maintenance. For specific items of pressure equipment or assemblies, more detailed
requirements on the content of operating instructions can be found in specific standards such as EN 13445
“Unfired pressure vessels”, EN 13480 “Industrial piping”, EN 12952 “Water-tube boilers and auxiliary installa-
tions”, or EN 12953 “Shell boilers”.
2 General
The manufacturer needs to identify and analyse all known and foreseeable hazards in the intended use and
clearly foreseeable misuse which may occur in mounting, putting into service, use, maintenance and in-
service inspections by the user of the pressure equipment.
Possible hazards which could not be eliminated in the design of the product or by secondary safety devices
are treated in Clause 3 of this document. These are residual hazards which can occur when a vessel is in-
stalled and used or operated under foreseeable conditions. Where appropriate, residual hazards are dealt with
in the operating instructions given by the manufacturer.
Operating instructions cover the information marked on the pressure equipment and are, where appropriate,
supported by technical documents, drawings and diagrams for a full understanding.
Depending on the type of pressure equipment:
a) a manufacturer may decide to put constraints on the use of the pressure equipment, e.g. in the case of
series products or “catalogue” products, or
b) a user/client may – e.g. via project specifications – put constraints on the design or the manufacture of
the pressure equipment.
In each of these cases, the constraints specified by the manufacturer (as in a)) or the solutions specified by
the client (as in b)) are identified in the operating instructions.
3 Hazard analysis
3.1 General
It is the purpose of the hazard analysis to enable the manufacturer to identify and determine the potential
modes of failure due to loading of pressure equipment which could occur when this equipment is installed and
used in reasonably foreseeable conditions.
Given below in 3.2 and 3.3 are hazards or combinations of hazards which need to be considered for operating
instructions. This list is not intended to be fully comprehensive, but illustrative of the scope of information
which needs to be taken into account.

g) decomposition of unstable fluids;
h) instability aspects;
i) incorrect handling of closures and openings;
j) dangerous discharge of pressure relief blow-off;
k) incorrect handling of devices to prevent physical access whilst pressure or a vacuum exists;
l) surface temperature taking into consideration the intended use;
m) incorrect handling of unstable fluids resulting in decomposition;
n) incorrect draining and venting with the following possible consequences:
1) water hammer, vacuum collapse, corrosion and chemical reactions;
2) inhibition of safe cleaning, inspection and maintenance in a safe manner;
o) failing of protection against corrosion or inadequate allowance of chemical attack of the materials;
p) excess wear;
q) incorrect assembly of components;
r) incorrect filling and discharge, e.g.:
1) overfilling or overpressurisation;
2) instability of the pressure equipment;
3) uncontrolled release of the pressurised fluid;
4) unsafe connection and disconnection;
kSIST-TP FprCEN/TR 764-6:2012
