When you have the plans, discuss with a club boiler inspector to gain advice on manufacture, and his confirmation that he will accept a boiler made to the plans for testing. Otherwise you may have a boiler he won't test or doesn't meet today's regulations. (Which is why I have converted 2 boilers recently to increase their strength to be able to be certified!).
I think most Martin Evans designs are still accepted in the UK. If you need calculations, I can do them for you, but would need to know the regulation limits relating to the certification as well. I have ASME and recently found a link to various States regs. I shall look-up regs for South Dakota...
I don't charge for doing the sums. - just message me personally if you need it.

PS: A clause (Below) may mean you do not need a Test and certification: CHECK WITH the regulator: That's something I can't do for you. He may want a copy of the boiler plans. To have a letter from him saying "you don't need a certificate" is very valuable! - If you can get one.
34-29A-26. Inspections required for operating boilers--Frequency of inspection.
Each boiler used or proposed to be used within this state,
except boilers exempt under §
34-29A-14, shall be thoroughly inspected as to their construction, installation and condition as follows:
(1) Power boilers and high pressure, high temperature water boilers shall receive a certificate inspection annually which shall be an internal inspection where construction permits, otherwise it shall be as complete an inspection as possible. Such boilers shall also be externally inspected annually while under pressure;
(2) Low pressure steam or vapor heating boilers shall receive a certificate inspection biennially with an internal inspection every four years where construction will permit;
(3) Hot water heating and hot water supply boilers shall receive a certification inspection biennially with an internal inspection at the discretion of the inspector;
(4) Boilers and pressure vessels which are a part of a nuclear installation shall be inspected and reported in such form and with such appropriate information as the Department of Public Safety shall designate.
A grace period of two months beyond the periods specified in subdivisions (1), (2), and (3) of this section may elapse between certificate inspections. The chief inspector may, at his discretion, permit longer periods between certificate inspections.
34-29A-14.
Boilers exempt from application of chapter.
This chapter does not apply to the following boilers:
(1) Boilers under federal control;
(2) Boilers located on farms if the farm is not regularly open to the general public and the boiler is used solely for agricultural or horticultural purposes;
(3) Heating boilers which are located in private residences or in apartment houses of less than six family units;
(4) Hot water supply boilers equipped with ASME-National Board approved safety relief valves which are directly fired with combustible fuel, electricity, or solar energy when none of the following limitations is exceeded:
(a) Heat input of two hundred thousand BTU per hour;
(b) Water temperature of two hundred ten degrees F;
(c) Nominal water capacity of one hundred twenty gallons;
(5) Boilers located in a refinery;
(6) Boilers used as part of an electrical generating plant;
(7) Historic power boilers as defined by §
34-29A-1. However,
each boiler shall comply with rules promulgated under the provisions of §

34-29A-1.
Definition of terms.
Terms as used in this chapter, unless the context otherwise requires, mean:
(1) "Boiler," a closed vessel in which water is heated, steam is generated, steam is superheated, or any combination thereof, under pressure or vacuum, for use externally to itself by the direct application of heat from the combustion of fuels, or from electricity, nuclear or solar energy. The term "boiler" includes fired units for heating or vaporizing liquids other than water where these units are separate from processing systems and are complete within themselves. The term "boiler" includes the apparatus by which heat is generated and all controls and safety devices associated with such apparatus or the closed vessel;
(2) "Certificate inspection," an inspection, the report of which is used by the chief inspector to decide whether or not a certificate as provided by §
34-29A-39 may be issued. This certificate inspection shall be an internal inspection when required; otherwise, it shall be as complete an inspection as possible;
(3) "Heating boiler," a steam or vapor boiler operating at pressures not exceeding fifteen psig,
(4) "High pressure, high temperature water boiler," a water boiler operating at pressures exceeding 160 psig or temperatures exceeding 250 degrees F;
(5) "Historic power boiler," a standard or nonstandard power boiler, including free-lance and scale models, owned by publicly operated museums, nonprofit organizations and
individuals who preserve, maintain, exhibit, and only occasionally operate these boilers on a not-for-profit basis and for the primary purpose of perpetuating the agricultural and pioneer heritage of South Dakota;
34-29A-14.1. Rules and regulations for inspection of historic power boilers.
The Department of Public Safety shall promulgate rules, pursuant to chapter
1-26, to provide for the inspection of those historic power boilers otherwise exempt from the provisions of this chapter by §
34-29A-14. The rules shall provide for the inspection of such boilers and for a check of the boiler's safety devices. The rules shall also establish an inspection fee for a historic power boiler inspection. The rules may provide for reporting requirements, inspection reports, repair standards, notification of repair and other administrative procedures necessary to implement this section. The operation of a historic power boiler without complying with the rules promulgated pursuant to this section, by the owner, user or operator of the boiler is a Class 2 misdemeanor. Each day of operation in violation of this section is a separate offense.
