A proposal for a new field of technical activity shall be submitted to the Office of the CEO (to tmb@iso.org),
which will process the proposal in accordance with ISO/IEC Directives, Part 1, Clause 1.5.
Furthermore, a proposal will be considered as complete if every information field is complete and follows theguidelines for proposing and justifying a new field of activity given in the ISO/IEC Directives, Part 1, Annex C.

Statement from the ISO Technical Management Board (TMB)
The TMB, through TMB resolution 54/2023 has chosen to postpone its decision reactivating ISO/TC 11
Boilers and pressure vessels. The reason for deferring the decision is to conduct an evaluation of thenecessity to reactivate ISO/TC 11 and to assess the level of active participation through a consultation to all
ISO Member Bodies.

TITLE(Please see the ISO/IEC Directives, Part 1, Annex C, Clause C.4.2)
Boilers and pressure vessels
SCOPE OF THE REACTIVATED TECHNICAL COMMITTEE(Please see the ISO/IEC Directives, Part 1, Annex C, Clause C.4.3)
Standardization of construction of boilers and pressure vessels.
Excluded:• railway and marine boilers covered by ISO/TC 8;• gas cylinders covered by ISO/TC 58;• aircraft and vehicle components covered by ISO/TC 20;• equipment used for fire-fighting covered by ISO/TC 21;• personal safety equipment covered by ISO/TC 94;• components of rotating or reciprocating devices;• nuclear pressure equipment covered by ISO/TC 85;• piping systems;

•cryogenic vessels covered by ISO/TC 220.

Note:
Construction is an all-inclusive term that includes design, materials, fabrication, examination, inspection, testing
and conformity assessment.
PURPOSE AND JUSTIFICATION FOR REACTIVATION(Please see the ISO/IEC Directives, Part 1, Annex C, Clause C.4.13)
The boilers and pressure vessels covered by ISO/TC 11 are vital equipment in industry, no matter in electric
power, petrochemical industry, light industry, or in food processing, metallurgy etc. They act as basic
equipment in heating and cooling systems for homes, offices, hospitals, schools or factories. The global trading
volume of boilers and pressure vessels are huge every year. And the need of setting global standards toregulate and facilitate free trade is urgent, which can improve the safety level of boilers and pressure vessels
and promoting the development of the global economy.
Besides, over the past 20 years, boilers and pressure vessels have been developing to the direction of large
size, severe parameters, harsh operation conditions and long running cycle. The demanding of carbon
emission control is attracting more and more countries concerns, coming with lightweight design, clean andefficient combustion and green energy etc. containing new demands for boilers and pressure vessels. At thesame time, the development of digital technology and artificial intelligence propels constructions of boilers andpressure vessels to be more digital, network and intelligence.
Over the past two decades, new materials and structures of boilers and pressure vessels have emerged.
Welding and non-destructive testing techniques have been developed rapidly. Correspondingly, many ISs formaterials, welding and non-destructive testing have been issued since the last revision of ISO 16528 publishedin 2007. The published ISs of ISO/TC44 (Welding and Allied Processes) and ISO/TC135 (Non-destructiveTesting) are about 321 and 96, respectively. Therefore, it is time to revise ISO 16528 to encompass the latest
development in the relevant fields. For example, ISO 9328 has introduced the materials and requirements fromrelated standards of the United States, EN, and Japan etc. The guideline for using materials from different
countries should be introduced in ISO 16528.Therefore, the national standards of different countries can selectmaterial according to ISO material standards(e.g. ISO 9328), which will reduce costs of products and promoteinternational trade. Standards such as ASME BPVC in the United States and GB/T 150 in China haverecognized some of each other's materials, which have greatly promoted bilateral trade.
In September 2021, The London Declaration to combat climate change through standards defines ISO’scommitment to achieve the climate agenda by 2050. Recently, all secretariats received the TMB action plan“ISO standards in support of action on climate change”. Boilers and pressure vessels play a significant role inimproving climate change. In addition to the consideration of quality and safety, the basic requirements ofenergy efficiency and environmental protection are also proposed to be introduced in the standards ofISO/TC11 to keep pace with the evolvement of ISO standardization system. Besides, according to the ISO
2030 strategy, the goals of digital, sustainable etc. have also put forward new requirements for ISO/TC11. It istime to unite more countries together and reach some consensus for the common goal of sustainable
development of mankind.
Due to the standby state, considering the issues of global concern, it is proposed that ISO/TC 11 could focus
on standardization in three directions in the future:(1) Fundamental standards with the basic requirements related to the quality and safety of boilers and pressurevessels. These standards can contribute to international trade and reduce manufacturing costs, such as
standards on general requirements for material mutual recognition, standard welding procedure specification ofpressure vessels.
(2) Deliverables related to addressing climate change. In order to meet the goals such as net zero guidelines
and the London Declaration, the existing standards (ISO 16528-1 and ISO 16528-2) should be revised toinclude climate considerations; while new standards for improving climate changes relating to boilers andpressure vessels could be developed, e.g. new standards about the basic requirements for energy efficiency
evaluation of high energy consuming boilers and heat exchangers.
(3) Deliverables related to new types of boilers and pressure vessels, especially those used in clean energy
industry, including new IS/TS/TR/PAS/IWA of construction methods, materials, and products. For example,
IS/TS/TR/PAS/IWA of the design methods for new types of heat transfer and storage collector tubes andspecially-shaped heat exchangers; and the performance requirements and testing methods of long-life heattransfer and storage medium such as molten salts and heat-conducting oils.
Experts related to boilers and pressure vessels from various countries shall get back together and use theplatform of ISO/TC11 to give deliverables to improve safety and quality of the two products and contribute toclimate change.
PROPOSED RE-ESTABLISHED PROGRAMME OF WORK
Please see the ISO/IEC Directives, Part 1, Annex C.4.4 and C-4.5)
For each item, the initial work programme shall define the deliverable type and target dates. The re-establishedwork programme shall also assign priorities to the different items.
The proposed work:(1) Revising standards-ISa) Revising ISO 16528-1:2007 Boilers and pressure vessels – Part 1: Performance requirementsb) Revising ISO 16528-2:2007 Boilers and pressure vessels- Part 2: Procedures for fulfilling the requirementsof ISO 16528-1(2) New proposalsa) Guidelines for Mutual Recognition of Pressure Vessels Materials-ISb) General Requirements for Standard Welding Procedure Specification of Pressure Vessels-ISc) Energy Efficiency Testing and Evaluation of Plate-and-Frame Heat Exchangers-ISd) Energy Efficiency Evaluation of High Energy Consuming Boilers-ISe) Failure-based Method for Design of Internally Pressurized Ellipsoidal and Torispherical Heads-TR
Note: Due to the standby state, the chair hopes to reactivate ISO/TC11.So that ISO members can have aplatform to submit new proposals and communicate with each other. Especially to climate change, boilers andpressure vessels cannot be absent.
