1 Scope

GB/T 12494-2025 is the Chinese national standard on white oil for food-machinery, in the field of petroleum and related technologies. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 5 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2026. Classification: ICS 75.140, CCS E42. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the product classification, technical requirements and test methods, sampling and batching, marking, packaging, and transportation of white oil for food machinery. Storage and delivery acceptance. This document applies to white oil specifically for food machinery, produced from petroleum distillates through dewaxing, hydrorefining, or chemical refining. The product is suitable for cooling, sealing, and lubrication of processing machinery and equipment that do not directly contact food, such as food processing, beverage processing, and drinking water transportation.
