标准摘要
[中文适用范围]： 本测量与计算程序用于确定立式圆柱形储罐的直径，方法是通过外部垂直偏移测量，采用光电测距设备而非传统的吊垂/小车设备。本标准是第2.2B章的替代标准，需与第2.2A章配合使用。绝缘储罐的校准由第2.2D章涵盖。存在凹陷或其他可见损伤迹象的异常变形储罐不在本标准的适用范围内。 [外文原描述]： Describes measurement and calculation procedures for determining the diameters of upright cylindrical tanks by taking vertical offset measurements externally using electro-optical distance ranging equipment rather than conventional ORLM plummet/trolley equipment. This standard is an alternate standard to Chapter 2.2B. This standard is used in conjunction with Chapter 2.2A. Calibration of insulated tanks is covered by Chapter 2.2D. Abnormally deformed tanks that are dented or have other visible signs of damage are not covered by this standard.
