强检计量器具赋码及动态监管系统

<正>为了配合计量部门对强检计量器具的有效管理,陕西烽火电子股份有限公司研发了强制检定计量器具赋码管理系统。本系统提出了"客户信息和样品信息唯一性"概念,设计了"客户信息和器具信息唯一性动态保障系统"。在器具唯一性得到保障的基础上,利用检定机构现有数据,自动为每个送检过的企业建立属于自己的计量器具库。企业可对其进行台账导入、在线管理、网上送检、送检进度查询等操作。同时,通过定期与检定机构的数据交换,周期检定数据得以自动更新。而基     

计量器具现场校准、检定、测试管理方法的探讨

在计量器具的校准、检定、测试过程中,经常出现使用单位要求检定人员到现场校准、检定或测试计量器具的情况,但由于检定场地是"送检"还是"现场"未做清晰界定,轻则造成器具检定不及时、过期未检,重则造成超周期使用,对科研、生产产品质量构成威胁,该文就这一问题提出相应的管理办法并进行探讨。     

计量器具溯源周期的确定方法

计量器具的准确与否是决定测量结果准确度和可靠性的重要基础。计量器具只有定期的通过检定或校准的方式进行溯源才能及时掌握计量器具的准确程度,以判定计量器具是否满足继续使用的要求。计量器具依据法制管理的要求可分为强制检定计量器具和非强制检定计量器具。强制检定的计量器具必须依据计量检定规程定期进行检定,非强制检定的计量器具溯源周期需要通过合理的评判标准来确定,同时根据计量器具的使用状态,使用年限及时调整溯源周期,实现对计量器具溯源周期的动态管理,在节约溯源成本的同时,保证计量器具的准确度和可靠性。     

关于计量器具检定周期的相关探究

计量器具检定周期在计量器具检定工作中起到了至关重要的作用,检定周期的长短影响着检定合格率、送检工作的频次以及企业备表的比重。本文主要阐述了计量器具检定周期的重要性,并对确定计量器具检定周期的原则和提高检定周期的几种方法进行初步探讨。     

计量强检工作信息化思考与实践

正一、引言按照财政部和国家发改委要求,从2017年4月1日起强制检定计量器具检定业务停征收费。由此,全国各地出现了计量技术机构互相推诿的现象,主要表现在,以标准器送检或标准器故障为由拒绝接收强检器具,或者以强制检定工作计量器具需要到行政部门备案为由,增加送检环节的繁琐与难度。导致大量的器具     

客户计量器具检定业务管理信息化设计与实现

客户计量器具检定业务管理信息化的设计与实现通过系统的、科学的管理方法,通过状态管理,规范了客户计量器具在计量检定企业的流转过程,杜绝了企业面临的经济与服务风险,提供了更加详细和准确的数据,完善和补充了对客户送检的计量器具以及所涉及费用的管理。     

如何做好企业能源计量服务

一、企业能源计量管理现状 1.部分企业对能源计量的重要性认识不足,片面追求产量和产值,忽视能源计量. 2.部分能源计量器具安装不科学,配备不符合GB17167-2006《用能单位能源计量具配备和管理通则》的要求;能源计量器具检定、校准不及时,特别是拆卸难度较大的仪器仪表,不能做到定期检定,从而难以保证其准确度;有些能源计量器具检修不及时,甚至损坏后不及时更换或不更换.

如何保障乡镇医疗计量器具量值准确

正由于各种原因,我县目前在用医疗计量器具管理的实际情况不容乐观,存在计量器具管理制度不完善,大多乡镇医院无具体的计量器具管理制度,有的医疗机构也只是在其他规章制度中涉及一两条计量管理制度;全县医疗计量器具送检率不平衡,存在偏远乡镇卫生院送检率低、部分在用计量器具送检率偏低、部分送检计量器具一次性检定合格率低等问题。主要原因有以下4个方面:一是医疗机构计量法制意识淡薄,计量管理基础薄弱,不熟悉

Metrology in Chemistry in Germany

The system for Metrology in Chemistry in Germany is described. At the national standards level, a network of high-level chemistry institutes coordinated by the national metrology institute, PTB, provides the primary references for chemical measurements. A dissemination mechanism employs chemical calibration laboratories accredited within the framework of the German Calibration Service (DKD). They act as “multipliers” between the national standards level and the user level by providing the user with calibration means which are traceable to the SI via national standards. Traceability structures in clinical chemistry, electrochemistry, elemental analysis and gas analysis are described

Natural radioactivity in drinking water in private wells in Finland

Natural radioactivity in drinking water was determined in population-based random study of 472 private wells. The mean concentrations of (222)Rn, (226)Ra, (234)U, (238)U, (210)Pb and (210)Po in drilled wells were 460, 0.05, 0.35, 0.26, 0.04 and 0.05 Bq l(-1), and in wells dug in the soil were 50, 0.016, 0.02, 0.015, 0.013 and 0.007 Bq l(-1), respectively. Approximately 10% of the drilled wells exceeded a radon concentration of 1000 Bq l(-1) and 18% a uranium concentration of 15 microg l(-1). The mean annual effective dose from natural radionuclides for a drilled well user was 0.4 mSv and 0.05 mSv for a user of a well dug in the soil. The effective dose arising from (222)Rn was 75% of the total of all natural radionuclides for drilled well users. As regards long-lived radionuclides, (210)Po and (210)Pb caused the largest portion of the effective dose. The dose arising from (238)U, (234)U and (226)Ra was only 8% of the total of all natural radionuclides.     

Trends in alcohol-impaired driving in Canada

While a general decreasing trend in the number of persons killed in a traffic crash involving a drinking driver has occurred in Canada since the 1980s, it is evident that much of this decrease occurred in the 1990s. Since 2002, less progress has been made as the number of persons killed in crashes involving drinking drivers remains high. To better understand the current situation, this paper describes trends in drinking and driving in Canada from 1998 to 2011 using multiple indicators based on data collected for the Traffic Injury Research Foundation's (TIRF) Road Safety Monitor (RSM), the National Opinion Poll on Drinking and Driving, and trends in alcohol-related crashes based on data collected for TIRF's national Fatality Database in Canada. There has been a continued and consistent decrease in the number of fatalities involving a drinking driver in Canada. This remains true when looking at the number of fatalities involving a drinking driver per 100,000 population and per 100,000 licensed drivers. This decreasing trend is also still apparent when considering the percentage of persons killed in a traffic crash in Canada involving a drinking driver although less pronounced. Data from the RSM further show that the percentage of those who reported driving after they thought they were over the legal limit has also declined. However, regardless of the apparent decreasing trend in drinking driving fatalities and behaviour, reductions have been relatively modest, and fatalities in crashes involving drivers who have consumed alcohol remain high at unacceptable levels.     

Radioactivity in building materials in Iraq

Activity concentrations of (226)Ra, (232)Th and (40)K in 45 samples of different building materials used in Iraq were measured using gamma-spectroscopy system based on high-purity germanium detector with an efficiency of 40 %. Radium equivalent activity, air-absorbed dose rate, annual effective dose, external and internal hazard indices and alpha index due to radon inhalation originating from building materials were measured to assess the potential radiological hazard associated with these building materials. The activity concentrations of the natural radionuclides (226)Ra, (232)Th and 40K were found to range from below detection limit (BDL) to 223.7 ± 9, BDL to 93.0 ± 3 and BDL to 343.1 ± 12, respectively. Values of average radium equivalent activity, air-absorbed dose rate, indoor and outdoor annual effective doses, external and internal hazard indices and alpha index ranged from 6.5 to 124.9, 16.2 to 89.5 (nGy h(-1)), 0.08 to 0.44 mSv, 0.02-0.11 mSv, 0.09 to 0.53, 0.13 to 0.69 and 0.03 to 0.62, respectively. These values indicate a low dose. Therefore, the building materials used in the current study are quite safe to be used as building materials.
