Standard Specification for Laboratory Glass Graduated Burets 实验室玻璃刻度滴定管的标准规范
发布日期: 2024-11-01
1.1 本规范涵盖了适用于实验室使用的精密和通用等级玻璃滴定管的要求。 1.1.1 A类- 每个精密度等级的滴定管可标有字母“A”,以表示符合适用的结构和准确度要求 表1 和 表2 根据制造商的选择,每个滴定管可以标有永久序列号。 1.1.2 B类- 通用滴定管的基本设计与A级滴定管相同。但是,B类滴定管的体积公差应在A类滴定管允许的规定范围的两倍以内。这些滴定管不需要标记其类别名称或序列号。见 表1 和 表3 公差和尺寸要求。 附注1: 第十二届(国际)度量衡大会将升重新定义为“立方分米的特殊名称”,但同意继续使用升、毫升和毫升等术语,除非与最高精度的测量。对于容积式玻璃器皿,升的新旧含义之间的差异可以忽略不计。因此,无论是mL还是cm 3 可标记在本标准涵盖的器皿上。 1.1.3 本标准中未列出的规定容量的产品,当产品符合中列出的下一个较小容量标准产品的公差范围时,可指定A级公差 表1 . 1.2 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。
1.1 This specification covers requirements for glass burets of precision and general-purpose grades suitable for laboratory use. 1.1.1 Class A— Each buret of precision grade may be marked with the letter “A” to signify compliance with applicable construction and accuracy requirements in Table 1 and Table 2 . Each buret may be marked with a permanent serial number at the option of the manufacturer. 1.1.2 Class B— General purpose burets are of the same basic design as Class A burets. However, volumetric tolerances for Class B burets shall be within twice the specified range allowed for Class A burets. These burets need not be marked with their class designation or serial number. See Table 1 and Table 3 for tolerances and dimensional requirements. Note 1: The Twelfth General (International) Conference on Weights and Measures redefined the litre as a “special name for the cubic decimetre,” but agreed to permit continuance of the terms litre, millilitre, and mL, except in association with measurements of the highest precision. For volumetric glassware the difference between the old and new meanings of litre is negligible. Therefore, either mL or cm 3 may be marked on ware covered by this standard. 1.1.3 Product with a stated capacity not listed in this standard may be specified Class A Tolerance when product conforms to the tolerance range of the next smaller volumetric standard product listed in Table 1 . 1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
