Scope
This standard specifies the product quality grading, performance test methods, sampling methods, and grade evaluation methods for argon extraction equipment using the hydrogen deoxidation method or the low-temperature full rectification method in air separation units. This standard applies to argon extraction equipment with an argon production capacity greater than or equal to 10 m³/h in air separation units (hereinafter referred to as ASUs) that use air as raw material and produce oxygen, nitrogen, and argon products by low-temperature method. Note: In this standard, the production capacities of air, oxygen, and argon are all under standard conditions, i.e., at 0°C and 101.325 kPa (absolute pressure), with the unit being m³/h.
本标准规定了空气分离设备中采用加氢除氧法或低温全精馏法氩提取设备的产品质量分等、性能试验方法、抽样方法和等级评定方法。 本标准适用于以空气为原料，采用低温法生产氧、氮及氩气产品的空气分离设备（以下简称空分设备）中提取氩气产量大于或等于10m3/h 的氩提取设备。 注：本标准中空气、氧气及氩气产量均为标准状态，即0℃、101.325kPa（绝压）状态下的气体量，单位为m3/h。

This standard JB/T 53149-1999 specifies the product quality grading for argon extraction equipment, applicable to units using hydrogen deoxidation or low-temperature full rectification methods with a capacity ≥10 m³/h. It classifies products into three grades: qualified, first-class, and premium, and provides performance indicators for output and technical parameters (e.g., argon purity, impurity levels). Performance testing follows JB/T 8942, sampling is random from user-operated units, and grade evaluation is based on the lowest indicator. This revision replaces JB/T 53149-94, adding the low-temperature full rectification process and larger capacity specifications.
本标准JB/T 53149-1999规定了氩提取设备的产品质量分等，适用于采用加氢除氧法或低温全精馏法的设备，产量≥10m³/h。标准将产品分为合格品、一等品和优等品三个等级，并给出了产量和技术性能指标（如氩纯度、杂质含量等）。性能试验方法引用JB/T 8942，抽样在用户运行设备中随机抽取，等级评定按最低指标确定。本标准替代了JB/T 53149-94，增加了低温全精馏法流程和更大产量规格。
