1.1本试验方法涵盖辐射效应试验中用作电离源的电子直线加速器在单个电子脉冲中传递的剂量的量热测量。该测试方法设计用于能量范围为10至50 MeV的电子脉冲，仅适用于与所构造材料中的这些电子范围相比，热量计和待辐照试样都“薄”的情况。 1.2所述程序可用于以下情况:( 1. )单个脉冲中的剂量为5 Gy（500 rad）或更大，或( 2. )与量热计的热时间常数相比，可以在较短的时间内传递多个较低剂量的脉冲。可接受监测的每个脉冲的最小剂量取决于特定测试的变量，包括脉冲率、脉冲均匀性和热量计的热时间常数。 1.3直接对制作热量计块的材料进行剂量测定。其他材料中的剂量可通过本试验方法中给出的公式根据该测量值计算。此类计算的需要和计算材料的选择应经试验各方同意。 1.4以国际单位制表示的数值应视为标准。括号中的值仅供参考。 1.5 本标准无意解决与其使用相关的安全问题（如有）。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====== 在辐射效应测试期间，有必要对剂量进行准确测量，以确保所采集数据的有效性，能够对不同设施采集的数据进行比较，并验证部件或电路是否按照适用于其使用系统的辐射规范进行了测试。 量热法测量剂量的主要值是结果是绝对的。它们仅基于材料的物理性质，即量热计块材料的比热和所用热电偶的塞贝克电动势或电阻的温度系数( α )使用的热敏电阻，所有这些都可以通过非辐射测量建立。 该方法允许在辐射效应试验期间进行重复测量，而无需在测量之间进入辐射室。

1.1 This test method covers a calorimetric measurement of the dose delivered in a single pulse of electrons from an electron linear accelerator used as an ionizing source in radiation-effects testing. The test method is designed for use with pulses of electrons in the energy range from 10 to 50 MeV and is only valid for cases in which both the calorimeter and the test specimen to be irradiated are" thin" compared to the range of these electrons in the materials of which they are constructed. 1.2 The procedure described can be used in those cases in which ( 1 ) the dose delivered in a single pulse is 5 Gy (500 rad) or greater, or ( 2 ) multiple pulses of a lower dose can be delivered in a time short compared to the thermal time constant of the calorimeter. The minimum dose per pulse that can be acceptably monitored depends on the variables of the particular test, including pulse rate, pulse uniformity, and the thermal time constant of the calorimeter. 1.3 A determination of the dose is made directly for the material of which the calorimeter block is made. The dose in other materials can be calculated from this measured value by formulas presented in this test method. The need for such calculations and the choice of materials for which calculations are to be made shall be subject to agreement by the parties to the test. 1.4 The values stated in SI units are to be regarded as the standard. The values in parenthesis are provided for information only. 1.5 This standard does not purport to address the safety concerns, if any, 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 ====== An accurate measure of the dose during radiation-effects testing is necessary to ensure the validity of the data taken, to enable comparison to be made of data taken at different facilities, and to verify that components or circuits are tested to the radiation specification applied to the system for which they are to be used. The primary value of a calorimetric method for measuring dose is that the results are absolute. They are based only on physical properties of materials, that is, the specific heat of the calorimeter-block material and the Seebeck emf of the thermocouple used or the temperature coefficient of resistance ( α ) of the thermistor used, all of which can be established with non-radiation measurements. The method permits repeated measurements to be made during a radiation effects test without requiring entry into the radiation cell between measurements.
