A proposal for a new field of technical activity shall be submitted to the Central Secretariat,
which will assign it a reference number and process the proposal in accordance with the ISO/IEC
Directives (part 1, subclause 1.5). The proposer may be a member body of ISO, a technicalcommittee, subcommittee or project committee, the Technical Management Board or a General
Assembly committee, the Secretary-General, a body responsible for managing a certification
system operating under the auspices of ISO, or another international organization with national
body membership. Guidelines for proposing and justifying a new field of technical activity are
given in the ISO/IEC Directives (part 1, Annex C).
The proposal (to be completed by the proposer)
Title of the proposed new committee (The title shall indicate clearly yet concisely the new
field of technical activity which the proposal is intended to cover.)Natural and engineered stones

Scope statement of the proposed new committee (The scope shall precisely define thelimits of the field of activity. Scopes shall not repeat general aims and principles governing
the work of the organization but shall indicate the specific area concerned.)
Definitions, requirements and test methods for natural stones relating to rough blocks, slabs, semifinished and finished products intended for use in building and for monuments and for engineeredstones with resin or cement binders or a combination of the two, intended for use in countertops
and vanities, floor and wall coverings, ancillary uses, for interior and exterior.

Proposed initial programme of work (The proposed programme of work shall correspond toand clearly reflect the aims of the standardization activities and shall, therefore, show therelationship between the subject proposed. Each item on the programme of work shall bedefined by both the subject aspect(s) to be standardized (for products, for example, theitems would be the types of products, characteristics, other requirements, data to besupplied, test methods, etc.). Supplementary justification may be combined with particular
items in the programme of work. The proposed programme of work shall also suggest
priorities and target dates.
The proposed initial programme of work is the development of test methods standards taking asa basis the existing European standards, which are also applied outside Europe, for example in
China and India.
The priority is given to the development of the following test methods:
Determination of chemical resistance
Determination of thermal shock resistance
Determination of the abrasion resistance
Determination of freeze and thaw resistance
Determination of impact resistance
Determination of linear thermal expansion coefficient
Determination of dimensional stability
Determination of dimensions and geometric characteristics
aiming to the characterization of both natural and engineered stones.
In order to achieve the global harmonisation of the information to be provided to the manufacturer
and the end user in terms of quality aspects, performance characteristics and safety requirementsof the products, standards dealing with definitions and requirements will be developed afterwards.
Moreover the intention is to work out International Standards also supporting the environmental
sustainability in the field of natural and engineered stones.
With reference to horizontal issues coordination with other existing TCs could be considered: forexample with TC 189 "Ceramic tile" for the currently developing PWI 23892 "Ceramic tiles – Slip
resistance of ceramic tile surfaces" in order to have aligned standards with reference to thestructure of the document, each one containing product's peculiarity.

Indication(s) of the preferred type or types of deliverable(s) to be produced under theproposal (This may be combined with the "Proposed initial programme of work" if moreconvenient.)
ISA listing of relevant existing documents at the international, regional and national levels.
(Any known relevant document (such as standards and regulations) shall be listed,regardless of their source and should be accompanied by an indication of theirsignificance.)
See annex.

Version 02/2016

A statement from the proposer as to how the proposed work may relate to or impact on
existing work, especially existing ISO and IEC deliverables. (The proposer should explain how
the work differs from apparently similar work, or explain how duplication and conflict will beminimized. If seemingly similar or related work is already in the scope of other committees ofthe organization or in other organizations, the proposed scope shall distinguish between theproposed work and the other work. The proposer shall indicate whether his or her proposal
could be dealt with by widening the scope of an existing committee or by establishing a newcommittee.)
These products have a worldwide distribution and for the time being there are no common ISO
standards available.

A listing of relevant countries where the subject of the proposal is important to theirnational commercial interests.
European trade area and China, Turkey, Brazil, Australia, Israel, Emirates, Russia, USA, South
Korea, South Africa, Canada, Vietnam, India, Iran, Oman.

A listing of relevant external international organizations or internal parties (other ISO and/orIEC committees) to be engaged as liaisons in the development of the deliverable(s). (Inorder to avoid conflict with, or duplication of efforts of, other bodies, it is important toindicate all points of possible conflict or overlap. The result of any communication withother interested bodies shall also be included.)
ASTA Worldwide Engineered Stone Manufacturers Association,Stone Federation, Euroroc

A simple and concise statement identifying and describing relevant affected stakeholder
categories (including small and medium sized enterprises) and how they will each benefit
from or be impacted by the proposed deliverable(s).
Manufacturers, laboratories, quarries, block sellers, retailers, distributors, stone masonries, endusers, architects, engineers, kitchen manufacturers, constructors, heritage organisations

An expression of commitment from the proposer to provide the committee secretariat if theproposal succeeds.
UNI-Italy is the proposer and is prepared to undertake the Chairmanship and the secretariat workrequired.

Purpose and justification for the proposal. (The purpose and justification for the creation ofa new technical committee shall be made clear and the need for standardization in thisfieldshall be justified. Clause C.4.13.3 of Annex C of the ISO/IEC Directives, Part 1 contains amenu of suggestions or ideas for possible documentation to support and purpose andjustification of proposals. Proposers should consider these suggestions, but they are notlimited to them, nor are they required to comply strictly with them. What is most important isthat proposers develop and provide purpose and justification information that is mostrelevant to their proposals and that makes a substantial business case for the market
relevance and the need for their proposals. Thorough, well-developed and robust purpose andjustification documentation will lead to more informed consideration of proposals andultimately their possible success in the ISO IEC system.)Global market of natural and engineered stones and harmonization of performance and safety
requirements on which the characterization of the products depends.
The international situation has changed over the past years, when only the European countries wereinterested to the use of these products and today the distribution of the final products andapplications are present worldwide.
The first priority for the work of the TC will be, therefore, the development of product specifications
for both natural and engineered stones and several supporting standards on test methods to assess
their performances.
