Dear Paul

I suggest everyone download the document (free) at

https://www.iso.org/obp/ui/#iso:std:iso:tr:21276:ed-1:v1:en

This is the work of the Conceptual Analysis group WG1 which created a harmonized set of definitions for the other working groups to use. It is a fine piece of work and I suggest that to the extent possible, you start using these carefully crafted sets of terms. Some of them are different from the usual and casual expressions we have used in the past. Some are the same.

What is very valuable is that for the first time we have a set of terms that can deal accurately with, for example, calculating the fuel needed to operate a stove that is used in the following manner:

Fire is lit and food cooked.
Remaining fuel is saved for another day, whether some of it, all of or even none of it.
New fuel is added to the fuel from yesterday which remains dried and partially burned. This process continues indefinitely.

Another example is the ability to express products of cooking and combustion in terms of the fuel or energy needed to produce them, whether than be heated water, boiled oil, cooked food, recoverable char, and reusable fuels.

These definitions can also serve to describe the performance of a two-stove system where one makes a charred fuel and another uses it, either singly as stoves, or as a pair evaluated as a single system.

I am not saying that the lab test can do these things, I am saying that the definitions are adequate for these purposes. A considerable portion of the philosophy contributing to this  flexibility comes from experiences in developing countries and the important work done in field observations and contextual testing where the simplistic methods of the past are not relevant or mislead investigators.

I was able to open the file and print my own copy to PDF using CutePDF (free).

It does not include the drawings of the energy and mass flows – the excellent work being paywalled. These concepts may be available from conference presentations by Prof Harold Annegarn who drafted them. When available, they can be circulated as art. They are very good for appreciating the concepts involved in tracing and reporting energy flows in a cooking or heating system.

I can also refer you to publications by Dr Yixiang Zhang and the group at CAU in Beijing. They have detailed energy flow charts covering both heating and cooking functions – probably the best available at present. The set of definitions is adequate to describe all the energy paths.

Best regards
Crispin

Stovers,

To have a copy of those standards will cost US$200.  That is a good way to NOT have the workers in the trenches gain easy access.

Let's hope that the people at the testing centers get copies and inform us of what is applicable.  (I suppose that they will purchase the document, or have some grantor make copies available).  I hope that they will spend the time to educate others.

Did you ever notice that the GACC does NOT send any informative messages (and certainly not any controversial discussion messages) to the Stoves Listserv.   The GACC makes posts at its website and expects to have the items read there.   I thank Nikhil for bringing this document to our attention.

I meant it is time for EPA/WHO/UNF to celebrate, that "international" flimflam went from Lima to IWA to ISO 19867-1 2018.

Regulator? What regulator? Gimme a break. Product standards agencies regulate commerce, not indoor air quality nor cooking. (For instance, clothes washers; think of all attributes the user needs or wants, and what a washing machine standard does. Standard for detergent is separate, and quality of water is yet another. It is presumed that the user hast clothes and water. Here, there ought to be no presumption that every user has same food ingredients in quality or quantity for every meal, or that somebody has fuel standards and indoor air quality standards).

This may be a "first step" to you. But without a contextual performance standard, all this Tier-ing is simply gearing toward more deception. Eating hash rather than smoking it.

That experts at ISO may be woke is no reason for me to get up and celebrate. Dope induces various layers of sleep. All that this document promises is " customization in reporting, while still maintaining harmonization in testing to compare products. "

I don't know a valid theory of change in use of solid fuel cookstoves that lab testing of theoretically usable stoves has to "maintain harmonization", just customize reporting.

If at all, I prefer your idea of reporting tests graphically rather than by a single number.

I don't think WBT is dead yet. Check with CDM and Gold Standard.

Even your hope for replicability in and across labs is misplaced. It is the actual use that matters.

The lesson that is yet to be learned is that only stoves that are usable and actually used merit lab testing in the first place. Otherwise carts will be piled in front of dead horses.

And usability and performance depend on "specific cohorts of users experiencing local conditions."

Next step -- morphology of "specific cohorts of users" and of "local conditions". Say, for 300 million out of 3 billion people.

I ain't woke. Blacked out from head punches. (See https://www.washingtoncitypaper.com/columns/straight-dope/article/13039270/straight-dope-the-physics-of-punching-someone-in-the-face<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.washingtoncitypaper.com%2Fcolumns%2Fstraight-dope%2Farticle%2F13039270%2Fstraight-dope-the-physics-of-punching-someone-in-the-face&data=02%7C01%7C%7Cab470494221d421042a808d5da3b9142%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636654871722917939&sdata=fpl49Bw90ceiywGErx8C6QzQ2FPxgymCsfWGd%2BaNO74%3D&reserved=0>. Getting heat and temperature right for different foods is more important than computing efficiencies and emissions per minute.)

Dear Nikhil

I seems the core message got through – without considering the context, the worth of a stove test is questionable for regulatory purposes.

Where the evaluation is directly relevant to the expected patterns of use, the assessment has value to a regulator.

The question of context is even more critical for program managers and policy makers because they are invariably focused on specific cohorts of users experiencing local conditions.

The next challenge is to see if the test method can produce replicable results, first within one laboratory and then between them.  As the test method is not testing apparatus-agnostic, the effort to adapt the Standard to a national one will in many cases require adapting the text to suit existing and broadly accepted, but significantly different practice. Reputations are earned, not given, so let’s have a go at the test and see what we get.

The WBT is dead. Long live something else.

Crispin

I can remember the joy when my writing was first published.

Whether or not it did any good to anybody, the feeling is relief, excitement, bubbling head.

" A key learning was the need to better reflect local context and practices, and the newly published document allows for customization in reporting, while still maintaining harmonization in testing to compare products. "

I wonder if experts are finally woke.

Mucho moolahs dangling on the trees.

The International Organization for Standardization (ISO) has published the first international standard for laboratory testing<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iso.org%2Fstandard%2F66519.html&data=02%7C01%7C%7Cdb0d89b0f9684e0c0b7108d5d9e81a21%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636654513243590369&sdata=%2B6kId61zQbh7eWgMLitGvg%2B29paLsRwYx3QGA81gjoQ%3D&reserved=0> of cookstoves. Developed and approved by international experts from 45 countries, the new standard includes protocols to test and report the emissions, efficiency, safety and durability of cookstoves in a lab setting.

"Standards play a critical role in virtually every industry, delivering transformative impact on safety and performance," said Sally Seitz, co-Secretariat of ISO Technical Committee 285 (ISO TC 285) and senior program manager at the American National Standards Institute. "With the publication of this standard, the clean cooking sector is poised to make significant strides toward better products and ultimately, toward improved outcomes for consumers who use them.”

The standard, which replaces an ISO International Workshop Agreement from 2012, is expected to serve as the basis for national policies and programs on cookstoves, while also incentivizing manufacturers and developers to improve stove quality and performance. An accompanying ISO technical report<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iso.org%2Fstandard%2F73935.html&data=02%7C01%7C%7Cdb0d89b0f9684e0c0b7108d5d9e81a21%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636654513243746620&sdata=ipKO8%2Bf%2BpXMDE1V8RRBRdEnGYY4nh20%2BjbV%2FbwB0wAI%3D&reserved=0> that benchmarks performance to voluntary performance targets, or tiers, and provides guidance on how to understand and interpret lab test results was also approved by member countries of the ISO Committee and will soon be published.

Development of the standard, which was supported by the Alliance, was informed by learnings about the advantages and limitations of previous protocols, as well as the latest sector research. A key learning was the need to better reflect local context and practices, and the newly published document allows for customization in reporting, while still maintaining harmonization in testing to compare products.

“The cooperation and dedication of experts from around the world has yielded the standard,” said Richard Ebong, convener of the ISO TC 285 lab testing working group and manager of legal metrology at the Ugandan National Bureau of Standards. “The responsibility is now with national standards organizations and other stakeholders to carry this forward in our countries. I shall do all that's within my powers to promote the standard.”

This voluntary document provides a framework for organizations, countries and regions to adapt and implement the protocols, metrics, and targets based on their priorities over the coming months and years. ISO standards are reviewed and updated regularly, so these standards can be updated based on future research and on the progress in the cookstove and fuel market.

ISO TC 285 also published a technical report<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iso.org%2Fobp%2Fui%2F%23iso%3Astd%3Aiso%3Atr%3A21276%3Aed-1%3Av1%3Aen&data=02%7C01%7C%7Cdb0d89b0f9684e0c0b7108d5d9e81a21%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636654513243746620&sdata=mwObQH%2BZnS%2FSB3NgAy%2B9Ml38L%2FaeIdLvBp69%2F%2F20Mno%3D&reserved=0> in May that provides harmonized definitions to key terms and concepts used within the sector. In addition, the ISO TC 285 has also been developing guidance on field testing, and it is currently open for ballot at the draft international standard phase. If approved, it is expected to reach the final phase of development in late 2018 or early 2019.
