    GB/T 16955-1997 - 中外标准 - - 1997/8 - 现行
    本标准规定了农林拖拉机和机械操作者位置处噪声的测量方法。本标准适用于操作者乘座操纵或步行操纵的拖拉机和机械,测量的噪声只与机械本身有关。  本标准规定的测试程序与GB/T 14259中简易法的测试程序相同。  本标准还规定了农林拖拉机和机械操作者位置处噪声测量和记录的基本要求。  在下列附录中规定了各种类型机械噪声测量的附加条件:  附录A(标准的附录) 农林拖拉机  附录B(标准的附录) 自走式农业机械  附录C(标准的附录) 步行操纵式农业机械  即录D(标准的附录) 林业集运机和集材拖拉机  测量期间,规定的机械运行状态,应使测量的噪声为真正的和可重复测定的,并且是操作者在操纵机械时能够遭受到的最大噪声。

  • ISO/ASTM 51900-2009 - 中外标准 - - 2009/6 - 现行
    ISO 51900:2009 applies to the minimum requirements for dosimetry needed to conduct research on the effect of radiation on food and agricultural products. Such research includes establishment of the quantitative relationship between absorbed dose and the relevant effects in these products. ISO 51900:2009 also describes the overall requirement for dosimetry in such research, and in reporting of the results. It is necessary that dosimetry be considered as an integral part of the experiment. ISO 51900:2009 applies to research conducted using the following types of ionizing radiation: gamma radiation, X-ray (bremsstrahlung), and electron beams. The purpose of ISO 51900:2009 is to ensure that the radiation source and experimental methodology are chosen such that the results of the experiment will be useful and understandable to other scientists and regulatory agencies. ISO 51900:2009 describes dosimetry requirements for establishing the experimental method and for routine experiments; however, ISO 51900:2009 is not intended to limit the flexibility of the experimenter in the determination of the experimental methodology. ISO 51900:2009 includes tutorial information in the form of notes. ISO 51900:2009 does not include dosimetry requirements for installation qualification or operational qualification of the irradiation facility.
