Oct 10 & 24, 2024
Presented by:
Djordje Srnić, M.Sc., P. Eng.
Administrator & Chief Inspector
Objective
To inform about:
• The major changes planned for the 2025 Edition of ASME BPVC
Section VIII Division 1;

• Future plans for development of ASME BPVC Section VIII Division 1

beyond 2025; and

• Changes in ASME BPVC Section VIII Division 2 that supports the

changes in Division 1.

2
100 years of ASME BPV Section VIII
• 1925 - Boiler and Pressure Vessel Code Section VIII Unfired
Pressure Vessels first issuance

• 1968 Edition – the Code title was changed to Rules for

Construction of Pressure Vessels, Division 1

• 2025 – major changes are planned for 100 years anniversary

List of major projects for
the 2025 Edition (100th anniversary)
To provide a new look of ASME BPVC Section VIII, Div.1 after the
Code’s 100th anniversary, ASME is conducting several projects
concurrently to better serve the users:

1. Scope and Exemption Revisions

2. Gender Neutral Language
3. Reshape Project
 ASME BPV Section VIII, Div. 1
1. Scope and Exemption Revisions 5
ASME BPV Section VIII, Div. 1
1. Scope and Exemption Revisions (1/3)
History
1930’s A controversy arose in the late 1930’s regarding determining
factors for the Jurisdictions
‒ This was an attempt to help Jurisdictions and harmonize exemptions

1940’s Exemptions were developed and these rules are still in the
Code
‒ 6-inch rule (currently U-1(c)(2)(i)) and
‒ 15 psi (currently U-1(c)(2)(h)(1)) as the minimum limits for the Jurisdictions

After 1940’s More exemptions were added but Jurisdictions are not
consistently applying them. (Jurisdictions apply their own
exemptions)
6
ASME BPV Section VIII, Div. 1
1. Scope and Exemption Revisions (2/3)
Issues
• BPV VIII has received numerous inquiries on the intended scope
– The ASME BPV Codes should not be responsible for determining which vessels
are to be included in or excluded from its scope of applicability
– The Jurisdiction should bear that responsibility.
• BPV VIII issued a generic interpretation in 2008
– This generic interpretation is being used to answer all future scope inquiries
• Pressure equipment that have large accumulated energy or high risk
were exempted without properly informing Jurisdictions
– Example: Long pressure vessels with the high MAWP (above 10,000 psi) and
diameter of just under 6 in were built to unknown codes using these Code
Exemptions without explaining the risk to the Jurisdictions.

7
ASME BPV Section VIII, Div. 1
1. Scope and Exemption Revisions (3/3)
Section VIII Task Group on Scope and Exemptions
• TG has been working on this problem since 2017
• Items approved for 2019 Edition were withdrawn even though they
were ready for publication
• Major comments received from HVAC and small vessel
Manufacturers
• The TG was revised to include as members individuals from the
HVAC industry and is to resolve the comments
• Comments are primarily associated with:
‒ Less than 6 inch diameter rule
‒ Water under storage rule
• The latest proposal of the scope changes passed the ballots in August
• The final discussion occurred during the August 2024 meeting to
address the ballot comments
• ASME’s plan is to resolve the issues and publish the scope revisions
in the 2025 Code Edition. 8
National Board Approach to
Provide Harmonized Approach
To help alleviate some concerns regarding jurisdiction oversight,
the National Board has formed a Task Group to initiate updates to
NB-131 – Recommended Boiler and Pressure Vessel Safety Legislation
NB-132 – Recommended Administrative Boiler and Pressure Vessel
Safety Rules and Regulations

NB-131 and NB-132 should provide a harmonized

approach and replace the exemptions that are
currently in the Scope of ASME BPVC VIII Div. 1
It will be up to Jurisdiction to adopt
NB-131 and NB-132
ASME BPV Section VIII, Div. 1
2. Gender Neutral Language
Diversity, Equity, and Inclusion
• ASME seeks to ensure all members and code users feel welcomed
and included in the ASME community
• ASME initiated a large project that will address any issues related to
diversity, equity, and inclusion throughout all ASME Code books
Identification of Issues
• The first step was to provide the gender-neutral language in the Code
Updating Section VIII to remove gender specific language
throughout the Code has been completed.
ASME’s plan is to publish the revisions in the 2025 Code Edition.
10
ASME BPV Section VIII, Div. 1

QUESTIONS?

36
APEGA and the
PESR
October 10 & 24, 2024
Presented by:
Robin Antoniuk, P.Eng.
Vice President Technical Services
Chief and Operating Officer
Objectives
• Review the previous definition of Professional Engineer in the
Pressure Equipment Safety Regulation (PESR)

• Look at the new definition of Professional Engineer in the

Pressure Equipment Safety Regulation (PESR)

• Discuss how this is applied and how it affects ABSA

stakeholders

2
One caveat….
• We are only talking about how this applies to ABSA and the
pressure equipment industry.
• We are not talking about your duties and obligations as a
professional engineer under APEGA. These are different
requirements.
• We’ll discuss this further later in the presentation.

3
Previous PESR Definition of P.Eng.
• 1(2) In this Regulation, a reference to a professional engineer
means a person who is registered as a professional engineer
in a professional organization and authorized to practise
engineering in any province or territory of Canada or in any
state of the United States of America
• This was the definition in the PESR from its inception in 2006
up until November 8th, 2023.

4
Problems with this definition…..
• ABSA had been made aware in the past by Alberta Municipal
Affairs (AMA) that this definition was not in alignment with the
Engineering and Geoscience Professions Act (EGPA).
• It’s the Engineering and Geoscience Professions Act that
defines Professional Engineer.
• The PESR does not have the authority to define what a
Professional Engineer is.

5
Problems with this definition…..
• It was around this time that APEGA’s new authentication
standard came out.
• ABSA and APEGA worked together on a document that
addressed several FAQ’s on how the authentication standard
would be applied to the pressure equipment industry.
• One of the questions in the FAQs addressed this definition
discrepancy.

6
Addressed in the APEGA/ABSA FAQs
Q: If ABSA requires a professional engineer to
authenticate (stamp and seal), does the PESR’s
definition of a professional engineer (s1(2) PESR)
supersede the EGP Act’s requirement that
authentication must be done by Alberta professional
engineers only?
A: No. Until legislative changes can be made, ABSA will not
be using s1(2) of the PESR and will defer to the EGP Act’s
s.1(v) for the definition of a professional engineer.
7
What does the EGPA say?
The Engineering and Geoscience Professions Act defines “Professional
Engineer” in Section 1(v) as:

“an individual who holds a certificate of registration to engage in the practice of

engineering under this Act but does not include
(i) a professional licensee (engineering), or
(ii)a professional technologist as defined in section 86.4(m)”

• This new definition replaced the old definition in the PESR on

November 8th, 2023.

8
How does APEGA apply this?
• APEGA would say where there’s any engineering done, this clause
would apply and the engineer in question must be a professional
member of APEGA, or have this work authenticated by a
professional member of APEGA.

• This would include pressure equipment designs, ITPs, repair plans,

alterations, when an engineer is specifically mentioned in codes and
standards such as CSA B51 and ASME.

9
How does APEGA apply this?
• For example, if you look at Annex J (normative) Requirements regarding
the use of finite element analysis (FEA) to support a pressure equipment
design submission of CSA B51-2019.
• J.3 states “The FEA analysis and reports shall be completed by individuals
knowledgeable in and experienced with FEA methods and pressure
equipment design. The FEA report shall be certified by a professional
engineer.”
• APEGA would say the engineer in question must be a professional
member of APEGA, or have this work authenticated by a professional
member of APEGA, regardless of where they’re located.

10
However…….
• AMA initiated a meeting with ABSA in December, 2023.

• During that meeting the direction given to ABSA by AMA, on behalf

of their legal and policy teams, was that the new definition of
“professional engineer” only applies when specifically mentioned in
the PESR.

• This only occurs in two places:

11
 Professional Engineer in the PESR
Complex designs and projects
9 If, in the opinion of a safety codes officer, the size or complexity of a design or project involving pressure equipment
may give rise to safety concerns, the safety codes officer may require that either or both of the following be
undertaken:
(a) all plans, documents and specifications, or any part of them, be affixed with the stamp or seal of a
professional engineer;
(b) the construction, installation, examination or testing of that pressure equipment be reviewed throughout the
course of that work by a professional engineer.

and

Pressure piping systems design submissions

16(2) The information referred to in subsection (1) must bear the stamp or seal of a professional engineer and the
name of
(a) the owner of the design, or
(b) the person who will be the manufacturer of the pressure piping system.

12
Professional Engineer in the PESR
• In both of these cases, the engineer submitting the complex design,
or the piping design, must be an APEGA licensed professional
engineer, or have their work authenticated by an APEGA licensed
professional engineer.

• But for other work, this would not be the case. Let’s revisit our
previous example:

13
How does APEGA apply this?
• For example, if you look at Annex J (normative) Requirements regarding
the use of finite element analysis (FEA) to support a pressure equipment
design submission of CSA B51-2019:
• J.3 states “The FEA analysis and reports shall be completed by individuals
knowledgeable in and experienced with FEA methods and pressure
equipment design. The FEA report shall be certified by a professional
engineer.”
• AMA would say the engineer in question DOES NOT have be a
professional member of APEGA, or have this work authenticated by a
professional member of APEGA.

14
Professional Engineer in the PESR
• Additionally, this means that things like pressure equipment
designs, ITPs, repair plans, alterations, won’t have to be created or
authenticated by an APEGA licensed professional engineer.

• For examples such as these, ABSA will default to the previous

definition in the PESR which stated:
“a person who is registered as a professional engineer in a
professional organization and authorized to practise engineering in
any province or territory of Canada or in any state of the United
States of America.”

15
HOWEVER, keep in mind…
• Everything we’ve talked about in this presentation is limited to the
requirements of the PESR and how ABSA delivers its services
– i.e. “what ABSA requires”

• As a professional engineer registered with APEGA, you are still

bound by the requirements set by APEGA and the Permit to
Practice you are operating under.

16
HOWEVER, keep in mind…
• For example, let’s look at a simple pressure vessel design submitted
to ABSA by a professional engineer outside of Alberta:

– ABSA would not require this engineer to be registered with APEGA or have
the design submission authenticated by an APEGA registered professional
engineer.

17
HOWEVER, keep in mind…
• For example, let’s look at a simple pressure vessel design submitted
to ABSA by a professional engineer:
– If the design is submitted by an APEGA licensed professional engineer, ABSA
would accept this without authentication, but APEGA would say you’re
compelled under the EGPA to authenticate the submission as part of your
duties as a P. Eng.
– ABSA has nothing to do with this. It’s between the APEGA licensed
professional engineer and APEGA.
– What’s acceptable to ABSA might not be acceptable to APEGA.
