美国环保局的高级工程师Jim Jetter是第二工作组的项目负责。在乌干达国家标准署的召集人的支持下以及60位国际专家的共同努力下，Jetter先生带领小组制定了ISO/CD 19867-1，这也将不久成为国际标准草案（DIS）。
ISO 19867的这一部分提供的是标准测试顺序，可以用来特定条件下不同灶具和燃料的性能。ISO 19867的制定主要为达成以下两个目标：（1）是进一步统一方法和参考数据；（2）是将这些方法和数据应用于鉴定发展中国家现有的各式不同的灶具燃料和烹饪活动。
另一个最近批准的委员会草案（CD）是ISO CD 19868，清洁灶具和干净烹饪方案。。在代理召集人Tara Ramanathan和美国Nexleaf分析中心的总监指导下，对灶具进行了现场测试方法的指导。这项国际标准将为评判烹饪系统性能提供实地测试方法。炊事系统的实地测试至关重要，用于了解使用时的性能和为影响评估提供输入数据。所有烹饪系统相关的元素，包括烹饪活动，燃料类型,灶具特点和环境条件都会影响性能。同时实地测试能进行在实验室中无法进行的炊事系统元素测量。
ISO TC 285 on Clean Cookstoves Releases Committee Drafts for Sustainable Cooking Technologies under U.S. and Kenya Leadership
The International Organization for Standardization (ISO) Technical Committee (TC) 285, Clean cookstoves and clean cooking solutions, has developed two Committee Drafts (CD) that support cooking system performance. These advancements are intended to provide cleaner sustainable cooking technologies, as health studies show that exposure to cookstove emissions, particularly in underdeveloped countries, is tied to a wide range of health effects and pollution. The American National Standards Institute (ANSI) serves as the ISO TC 285 secretariat in partnership with the Kenyan member body to ISO, the Kenya Bureau of Standards.
Formed in 2013, ISO TC 285 provides governments, industry, and organizations around the world with the opportunity to become involved in the process of designing, implementing, and updating standards related to clean cookstoves and clean cooking solutions. The TC operates with four active Working Groups (WGs) that focus on the potential development of standards and other essential documents in subject areas associated with clean cookstove technology. These groups include WG 1, Conceptual framework,WG 2, Lab testing methods, WG 3, Field testing methods, and WG 4, Social impacts.
Jim Jetter, senior research engineer at United States Environmental Protection Agency (EPA) serves as project leader for WG 2. Mr. Jetter, with support from the Convenor from the Uganda National Bureau of Standards, and with input from 60 international experts, leads the development of ISO/CD 19867-1 that will soon proceed to DIS (Draft International Standard).
ISO/CD 19867-1 Harmonized laboratory test protocols -- Part 1: General laboratory test sequence, is intended for use as laboratory measurement procedures to determine performance for cookstoves used primarily for cooking or water heating in the developing world. Its purpose is to provide metrics that can be used to indicate a cookstove’s performance under various controlled conditions.
This part of ISO 19867 provides a standard test sequence that can be used to compare the performance of various cookstoves and fuels under the specified conditions. ISO 19867 was developed to achieve two goals: (1) greater alignment in methodology and metrics around the world; and (2) adaptation of methodology and metrics to the wide variety of cookstove fuels and cooking practices that exist in the developing world.
Another recently approved CD is ISO CD 19868, Clean cookstoves and clean cooking solutions -- Guidance on field testing methods for cookstoves, under the direction of acting convenor Tara Ramanathan, StoveTrace program director at Nexleaf Analytics, U.S. This International Standard will provide field testing methods to evaluate cooking system performance. Field measurements of cooking systems are essential to understanding in-use performance and to provide input metrics for impact evaluations. All elements of the cooking system, such as cooking practice, fuel type, fuel quality, cookstove characteristics, and environmental conditions, affect performance, and field tests provide measurements that capture elements of the system that are infeasible to bring to the lab.
The standard, intended for manufacturers, implementing organizations, researchers, governments, or other entities that need to evaluate cookstove performance in the field, is projected to:
1) Provide quantitative measurements of cooking system performance. Guidance is provided for evaluation of adoption rates, fuel consumption, power, emissions, safety, and durability. These measurements can be obtained from uncontrolled and controlled cooking tests. However, guidance is provided for uncontrolled cooking tests, not controlled tests.
2) Provide methods for measurements of indoor air pollution and personal exposure to PM2.5 and CO.
3) Provide guidance for field assessments that compare cooking system performance metrics to defined performance levels, or to a counterfactual, which assesses if the new cooking system is improved compared to what would have been observed without the implementation of a new cooking system.
In addition to its leadership role as TC 285 secretariat with Kenya, ANSI also serves as the U.S. Technical Advisory Group (TAG) administrator to ISO TC 285, with technical and financial support from the Global Alliance for Clean Cookstoves, part of the United Nations Foundation. Ms. Sally Seitz serves as the U.S. Secretary and Dr. Ranyee Chiang serves as the chairperson through 2019.
