1、中华人民共和国行业标准表层型核子水分一密度仪现场测试规程Fieldtestmethodsfornuclearsurfacedensity-moisturegaugesSL275.1-2001中华人民共和国水利部关于批准发布《核子水分一密度仪现场测试规程》SL275-2001的通知水国科〔200幻39号部直属各单位，各省、自治区、直辖市、水利(水务)厅(局)，计划单列市水利(水务)局，新疆生产建设兵团水利局:经审查，批准《核子水分一密度仪现场测试规程》为水利行业标准，并予发布。标准编号为SL275-20010本标准自2002年3月1

2、日起实施。标准文本由中国水利水电出版社出版发行。2002年1月28日226水利水电卷·仪器前言利用核子法测定土石等材料原位密度和含水量是一项迅速发展起来的无损、快速检测新技术。目前，我国已有相当数量的各类进口和国产核子水分一密度仪在各类工程中使用，并成为质量检测和控制的一种重要工具。鉴于此，迫切需要制订一个专门的、统一的技术标准来指导和规范各类核子水分一密度仪的现场测试方法。本规程就是根据以上需要，按照水利部技监办[1996〕第14号文精神，在总结我国核子水分一密度仪工程现场测试应用的实际经验以及参考和借鉴国际、国内相关标准和技术

3、文献的基础上编写制定的。本规程由以下两个专题规程组成:—表层型核子水分一密度仪现场测试规程SL275.1-2001—深层型核子水分一密度仪现场测试规程SL275.2-2001每个专题规程包含以下内容:核子水分一密度仪的适用范围、有关术语、仪器器具、标准计数、现场标定、现场测试、报告书、测量精度和误差分析以及辐射防护安全。本规程解释单位:水利部国际合作与科学技术司本规程主编单位:南京水利科学研究院本规程主要起草人:程和森曹吏新标准分享网www.bzfxw.comSL275-1-200122，目次前言·················
