本文件提供了炉灶的自愿性能目标，旨在补充ISO 19867-1。这些自愿性能目标旨在与ISO 19867-1中规定的实验室测试结果一起使用。 这些自愿性性能目标是作为信息性指导提供的，并非炉灶测试的规范性要求。绩效目标可被视为衡量炉灶和清洁烹饪解决方案潜在绩效的一种方法，并为帮助组织和国家在家用能源技术、燃料和相关产品方面开展国际合作和贸易提供指导。 因此，本文件不打算作为决定在特定环境下推广哪些技术/燃料的唯一依据，因为在实际情况下，特定技术的性能可能会有所不同- 使用条件。评估炉灶干预或项目的实际影响的最佳方法是通过实地研究，见ISO 19869[1]，以及其他现有方法[2][3]。 除了因与真实世界性能的差异而产生的限制外，实验室测试指标（效率、排放、安全性和耐久性）并未告知对产品、计划或干预可能实现的影响至关重要的其他因素。这些因素包括但不限于地理/文化适宜性、价格承受能力、目标用户群体的可接受性以及其他社会经济因素。 这些自愿排放性能目标旨在评估用于小规模家用的炉灶，最大火力可达10千瓦。 火力在10千瓦以上的炉灶比功率在10千瓦以下的炉灶向家庭环境排放的污染物总量要大得多，同时仍能达到每兆焦耳有效能量排放克数的目标。 [1] 正在准备中。发布ISO/DIS 19869:2018时的阶段。

This document provides voluntary performance targets for cookstoves and is intended to supplement ISO 19867-1. These voluntary performance targets are intended for use with the results of the laboratory testing specified in ISO 19867-1. These voluntary performance targets are provided as informative guidance, and are not intended as normative requirements for the testing of cookstoves. Performance targets can be considered as an approach to benchmarking potential performance of cookstoves and clean cooking solutions, and provide guidance to help organizations and countries with international collaboration and trade in household energy technologies, fuels, and related products. This document is therefore not intended to serve as the sole basis for decisions about which technologies/fuels to promote for a given setting, since the performance of a given technology will likely differ under real-use conditions. The best way to assess real-world impacts of a stove intervention or program is through field studies, see ISO 19869[1], as well as other existing methods[2][3]. In addition to the limitations arising from differences from real-word performance, laboratory test metrics (efficiency, emissions, safety, and durability) do not inform other factors that are critical to the impacts a product, program, or intervention may achieve. These factors include, but are not limited to geographic/cultural suitability, price-affordability, acceptability to the target user group, and other socio-economic factors. These voluntary performance targets for emissions are intended to evaluate cookstoves used for small-scale household applications, with maximum firepower of up to 10 kW. Cookstoves that have firepower above 10 kW could emit substantially more overall pollutants into the household environment than those under 10 kW, while still meeting targets based on grams emitted per megajoule of useful energy delivered.
