ASTM E1270-88(2003) 等臂天平的测试方法

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.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, and1.2.6 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.

ASTM D4633-86 用动力贯入器试验系统测量应力波能的试验方法

1.1 This test method describes the procedure for measuring that part of the drive weight (hammer) kinetic energy that enters the penetrometer connector rod column during dynamic (hammer impact) penetrometer testing of soil. 1.2 This test method has particular application to the comparative evaluation of hammer systems, and, to a lesser degree of accuracy, hammer-operator systems, that are used for the penetration testing of soils. 1.3 This test method applies to penetrometers driven from above the ground surface. It is not intended for use with down-hole hammers. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only. 1.5 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
