1.1本试验方法可用于测试任何容量和灵敏度的等臂天平。测试程序应使用户能够充分描述其仪器的特性，以确定其是否适合使用目的。 1.2要检查的特性包括: 1.2.1所有负载下的灵敏度， 1.2.2杆臂比， 1.2.3阻尼比（对于没有附件阻尼器的仪表）， 1.2.4振荡周期， 1.2.5精度，以及 1.2.6提供称重指示的附件装置的线性和校准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 该测试方法应使天平的用户能够解释其上确定的数据的准确性和精密度。它应该有助于最大限度地利用特定工具。弱点和优势应该变得明显。本试验方法的目的不是比较不同制造商的类似仪器，而是帮助选择满足用户需求的仪器。

1.1 This test method can be used for testing equal-arm balances of any capacity and sensitivity. The testing procedure should enable the user to characterize his instrument sufficiently to determine whether or not it is suitable for the purpose for which it is to be used. 1.2 The characteristics to be examined include: 1.2.1 Sensitivity at all loads, 1.2.2 Lever arm ratio, 1.2.3 Damping ratio (for instruments without accessory dampers), 1.2.4 Period of oscillation, 1.2.5 Precision, and 1.2.6 Linearity and calibration of accessory devices that provide on-scale indication of weight. 1.3 This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method should enable the user of the balance to interpret data determined thereon in terms of accuracy and precision. It should be helpful in using a particular instrument to best advantage. Weaknesses as well as strengths should become apparent. It is not the intention of this test method to compare similar instruments of different manufacture but rather to assist in choosing an instrument which will meet the needs of the user.
