Gas Equipment and Handling

This document describes the techniques to be applied for the detection of a leak, using a tracer gas and a tracer gas specific leak detector.

Types of flanges from PN 6 to PN 40 and in sizes up to DN 1800. Facings, dimensions tolerances, bolt sizes, marking and materials for bolting and flange materials with associated pressure/temperature ratings.

Methods for the identification and assessment of hazardous situations leading to explosion and the design and construction measures appropriate for the required safety. This is achieved by:
- risk assessment;
- risk reduction.
The safety of equipment, protective systems and components can be achieved by eliminating hazards and/or limiting the risk, i.e. by:

IEC 60730-2-6:2015 applies to automatic electrical pressure sensing controls with a minimum gauge pressure rating of -60 kPa and a maximum gauge pressure rating of 4,2 MPa, for use in, on or in association with, equipment. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof.

2. These regulations apply
(a) to all boilers, pressure vessels and plants to which the Act applies;
(b) to all pressure piping, fittings or other equipment attached to or used in connection with boilers or pressure vessels to which the Act applies;
(c) to all operating engineers, operators and welding operators to whom the Act applies; and
(d) to all work performed on boilers, pressure vessels, plants and equipment referred to in paragraphs (a) and (b).

IEC 62282-2:2012 provides the minimum requirements for safety and performance of fuel cell modules; it applies to fuel cell modules with or without an enclosure which can be operated at significant pressurization levels or close to ambient pressure. Deals with conditions that can yield hazards to persons and cause damage outside the fuel cell modules. This edition includes the following significant technical changes with respect to the previous edition:
- inclusion of definitions for hazards and hazardous locations based on the IEC 60079 series;

ISO 22734-1:2008 defines the construction, safety and performance requirements of packaged or factory matched hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water to produce hydrogen and oxygen gas.
It is applicable to hydrogen generators that use the following types of ion transport medium:
Group of aqueous bases;
Solid polymeric materials with acidic function group additions such as acid proton exchange membrane (PEM).

ISO/TR 15916:2015 provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). It identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards.
"Hydrogen" in this paper means normal hydrogen (1H2), not deuterium (2H2) or tritium (3H2).

This International Standard specifies the essential requirements for fuel cell vehicles (FCV) with respect to the protection of persons and the environment inside and outside the vehicle against hydrogen-related hazards.
It applies only to such FCV where compressed hydrogen is used as fuel for the fuel cell system.
This International Standard does not apply to manufacturing, maintenance, and repair.
The requirements of this International Standard address both normal operating (fault-free) and single-fault conditions of the vehicles.
