Manufacturers and quality inspection agencies in the dye and chemical industries use this standard to test and control the quality of carbazole products. It sets key specifications such as purity, melting point, and impurity levels to ensure products meet different grades (premium, first, qualified). This standard provides a unified technical basis for procurement, acceptance, and market circulation of carbazole.
染料和化工行业的生产企业、质检机构使用本标准来检测和控制咔唑产品的质量。通过规定纯度、熔点、杂质含量等关键指标，确保产品符合不同等级（优等品、一等品、合格品）的要求。该标准为咔唑的采购、验收和市场流通提供了统一的技术依据。

This standard HG/T 4259-2011 specifies quality requirements, sampling methods, test procedures, inspection rules, and packaging, transport, and storage requirements for the chemical product carbazole. Carbazole is classified into premium, first, and qualified grades based on purity, with key tests including appearance, dry initial melting point, carbazole purity, and impurity levels of anthracene, low boilers, and high boilers. Purity is determined by capillary gas chromatography with flame ionization detection and peak area normalization. The standard also defines出厂 inspection, re-inspection rules, and labeling requirements, serving as a technical basis for carbazole quality control.
本标准HG/T 4259-2011规定了化工产品咔唑的质量要求、采样方法、试验步骤、检验规则及包装运输贮存要求。咔唑按纯度分为优等品、一等品和合格品，主要检测外观、干品初熔点、咔唑纯度及蒽、低沸物、高沸物等杂质含量。纯度测定采用毛细管气相色谱法，以峰面积归一化法定量。标准还明确了出厂检验、复验规则及标志标签要求，适用于咔唑产品的质量控制。
Key Sentences extracted from text
本标准规定了咔唑的要求、采样、试验方法、检验规则以及标志、标签、包装、运输和贮存。
咔唑的质量要求应符合表1的规定。
采用毛细管柱气相色谱法，分离咔唑及其有机杂质，用氢火焰离子化检测器进行检测，采用峰面积归一化法定量。
咔唑纯度平行测定结果之差应不大于0.10％，各有机杂质平行测定结果之差应不大于0.02％，取其算术平均值作为测定结果。
如果检验结果中有一项指标不符合本标准的规定时，应重新自两倍量的包装中取样进行检验，重新检验的结果即使只有一项指标不符合本标准的要求，则整批产品不合格。
This standard specifies the requirements, sampling, test methods, inspection rules, as well as marking, labeling, packaging, transport and storage of carbazole.
The quality requirements of carbazole shall comply with the provisions of Table 1.
Use capillary column gas chromatography to separate carbazole and its organic impurities, detect with a flame ionization detector, and quantify by peak area normalization method.
The difference between parallel determination results of carbazole purity shall not be greater than 0.10%, and the difference between parallel determination results of each organic impurity shall not be greater than 0.02%, and the arithmetic mean shall be taken as the determination result.
If any indicator in the inspection results does not meet the requirements of this standard, sampling shall be repeated from double the quantity of packaging for inspection; if even one indicator in the re-inspection results does not meet the requirements of this standard, the entire batch of products is deemed unqualified.
