文档大全 二 比重瓶校验方法 本方法适用于新的或使用中的比重瓶。 （一）概述 比重瓶用于粒径小于5mm的土及其他粉状物料比重（密度）测定。 （二）技术要求 2.1 外观：无裂纹或其它明显变形。 2.2 容积：经测量得出不同温度下的瓶水质量，准确至1mg，两次差值。0.02g （三）校验用标准工具 3.1 电子天平：称量1100g，感量0.01g。 3.1 温度计：刻度范围0~50℃，精确至1℃。 （四）环境条件 温度：20℃~24℃；相对湿度：≤75%。 （五）校验方法 5.1 外观：目测。 5.2 比重瓶计算校正法： 5.2.1 将比重瓶洗净、烘干，在干燥器内冷却称量m01，准确至0.01g，再次烘干冷却后称量m02。两次差值不大于0.02g，取其算术平均值m0。 5.2.2 将事先煮沸并冷却至室温的纯水注入比重瓶至满，塞上瓶塞，使多余的水沿瓶塞毛细管中溢出，擦干瓶外表面的水，称其瓶、水总质量m11，准确至0.01g，重复上述步骤，取其算术平均值m1，两次差值不得大于0.02g。 5.3 按公式计算m2：

m2= 式中：Ｔ１──比重瓶内纯水温度℃ Ｔ２──比重瓶内纯水任意温度℃ ｍ１──温度为Ｔ１时的瓶水总质量 ｍ２──温度为Ｔ２时的瓶水总质量 ｍ０──比重瓶的质量 ＰＷ１──温度Ｔ1时水的密度 ＰＷ２──温度Ｔ2时水的密度 ωＶ──玻璃的膨胀系数，国产瓶可取2.4×10-5/℃ （六）校验结果处理 校验结果符合技术要求为合格，合格者方可使用。 （七）校验周期 一年。 （八）附录 校验记录表格式。
