Scope

This document specifies the classification, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of chloride-based snow melting agents. This document applies to chloride-based snow melting agents prepared primarily from sodium chloride, calcium chloride, and other raw materials, which can be used for snow and ice removal on highways and urban roads, concrete and asphalt pavements, and public facilities such as bridges and culverts. This document does not apply to industrial salt by-products. With the increasing demand for winter road snow removal in China, traditional chloride-based snow melting agents, while ensuring traffic flow, have also exposed prominent issues such as strong corrosiveness to road facilities and high ecological environmental risks. Existing products vary in performance, and there is a lack of comprehensive and unified standards for environmental protection and efficiency evaluation, leading to industry chaos and lagging technical upgrades. Therefore, it is urgent to formulate scientific and standardized quality and multi-scene application standards for chloride-based snow melting agents to balance snow melting efficiency and ecological safety and promote high-quality development of the industry. The preparation of this document aims to address the following core issues by defining the technical requirements, test methods, and usage norms for high-efficiency and environmentally friendly chloride-based snow melting agents: First, standardize product performance and strictly control environmental indicators such as toxic and harmful substances and relative harm rates of plant seeds to reduce long-term impacts on soil, water bodies, and vegetation. Second, based on the principle of graded and classified use, implement fine management of the usage amount of chloride-based snow melting agents in different application scenarios. Through standardization, promote the industry to transition
