B51-14, Part 1 - General requirements for boilers, pressure vessels, and pressure piping
B51-14, Part 2 - High-pressure cylinders for the on-board storage of natural gas and hydrogen as fuels for automotive vehicles
Part 2 of this Standard concerns high-pressure cylinders for the on-board storage of natural gas, blends of natural gas and hydrogen (hydrogen blends), and hydrogen as fuels for automotive vehicles. The use of gas cylinders is governed by the Act. Users and manufacturers should note the need to apply to the applicable regulatory authorities for approval of gas cylinders.
Part 2 of this Standard specifies minimum requirements for serially produced lightweight refillable gas cylinders, both original equipment and conversions, having a water capacity exceeding 20 L (0.71 ft3) but not exceeding 1000 L (35.3 ft3). Part 2 of this Standard applies only to cylinders for the on-board storage of high-pressure compressed natural gas and/or compressed hydrogen as fuels for automotive vehicles to which the cylinders are to be fixed. Cylinders may be of any material (steel, aluminum, or non-metallic) and constructed in accordance with any design or method of manufacture suitable for the specified service conditions.
The cylinders covered by Part 2 of this Standard are designated as follows:
(a) Type 1 - metal;
(b) Type 2 - metal liner reinforced with resin-impregnated continuous filament (hoop-wrapped);
(c) Type 3 - metal liner reinforced with resin-impregnated continuous filament (fully wrapped); and
(d) Type 4 - non-metallic liner with resin-impregnated continuous filament (all-composite).
The service conditions to which the cylinders are subjected are specified in Clause 4. Part 2 of this Standard is based on a working pressure settled at 15 ¦C (59¦F), with a maximum filling pressure of 1.25 times the working pressure.
The service life of a cylinder is defined by the manufacturer and can vary with different applications. This Standard's definition of service life is based on filling a cylinder 750 times a year. The maximum service life of Type 2, Type 3, and Type 4 cylinders is 20 years. For all cylinders, a safe life design principle is used.
For metal and metal-lined cylinders, the cylinder life is based on the rate of fatigue crack growth. Ultrasonic or equivalent inspection of each cylinder or liner is necessary to ensure that there are no flaws that exceed the maximum allowable size determined by fracture mechanics. This approach optimizes the design and manufacture of lightweight cylinders for natural gas vehicle service.
For all-composite cylinders with non-metallic non-load-bearing liners, safe life is ensured by appropriate design methods, design qualification testing, and manufacturing controls.
Part 2 of this Standard does not cover Type 1 or Type 2 welded metal cylinders or liners.
Where a clause in Part 2 of this Standard is at variance with codes or standards referenced in Part 2 of this Standard, the requirements of Part 2 of this Standard govern.
Type 1 steel cylinders may be requalified for further service in accordance with the procedure described in Annex B.
B51-14, Part 3 - Compressed natural gas and hydrogen refuelling station pressure piping systems and ground storage vessels
The pressure piping systems covered in Part 3 of this Standard are systems used in compressed natural gas (CNG) and hydrogen refuelling stations
(a) between the termination of the utility's piping, usually at the meter, and the inlet to the compressor assembly if the design pressure exceeds 414 kPa (60 psi); and
(b) from the inlet to the compressor assembly through to the dispenser nozzle, except for the mechanical parts of the compressor and any subsystems designed for 414 kPa (60 psi) or less.
The ground storage vessels covered in Part 3 of this Standard are pressure vessels that are installed at CNG and hydrogen refuelling stations and intended to store CNG or hydrogen at pressure for delivery to vehicle fuel tanks.
Where a clause in Part 3 of this Standard is at variance with codes or standards referenced in Part 3 of this Standard, the requirements of Part 3 of this Standard govern.
ANSI Z21.21-2015/CSA 6.5-2015
ANSI Z21.21-2015/CSA 6.5-2015 - Automatic valves for gas appliances
This is the fifth edition of ANSI Z21.21 / CSA 6.5, Automatic valves for gas appliances. It supersedes the previous editions published in 2012, 2005, 2000, and 1995.
A control that incorporates two or more automatic valves and no other function, (as defined by combination control, see Clause 3), may be tested to this Standard or to the Standard for Combination Gas Controls for Gas Appliances, ANSI Z21.78 / CSA 6.20, at the discretion of the manufacturer.
This Standard applies to automatic valves having maximum operating gas pressure ratings from ╜ psi (3.5 kPa) up to and including 60 psi (413.7 kPa). This Standard also applies to C/I valves having maximum operating gas pressure ratings of ╜ psi (3.5 kPa) or greater (see Clauses 6 and 7).
This Standard applies to automatic valves that are to be mounted in the manufacturer's specified upright position or in one (1) or more of the optional mounting positions selected by the manufacturer. (See Clause 5.1.1).
This Standard applies to automatic valves that are capable of operation at ambient temperatures of 32 F to 125 F (0 C to 51.5 C), unless a higher temperature, lower temperature, or both, are specified by the manufacturer. (See Clause 5.1.2).
In this Standard, shall is used to express a requirement, i.e., a provision that the use shall satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised by not required; and may is used to express an option or that which is permissible with the limits of the standard.
The CSA Subcommittee on Hearing Protection recognizes that significant variations in performance (as great as 20 dB attenuation) can occur depending on how an HPD is used. This Standard emphasizes the importance of a comprehensive hearing loss prevention program, including hazard assessment and instruction on the careful selection, proper wearing, and high-quality maintenance of hearing protection devices. It is the opinion of the Subcommittee that wearing HPDs without proper selection, care, and use can result in significantly lower attenuation for the user than that obtained from the tests specified in this Standard.
