摘要/Abstract

摘要： 目的了解广东省从事工作场所手传振动测量工作的职业卫生技术服务机构的测量仪器性能。方法 2023年9月,以整群抽样方式,在具有手传振动检测能力的93家广东省辖区内从事工作场所手传振动测量工作的职业卫生技术服务机构各选取1台仪器为研究对象,收集统计其最近1次的检定/校准证书相关信息。以SV111便携式振动校准器作为核查标准源,核查各机构手传振动测量仪器在“15.92 Hz、1 m/s²”“79.58 Hz、10 m/s²”和“159.20 Hz、10 m/s²”3个频率各1个加速度水平下测量值与标准值的误差计算得分,满分为18分,以取得≥11分判定为合格。结果 93家机构的仪器检定校准测量读值均在最大允差范围内,但93份计量机构出具的检定校准证书中,有85份（91.4%）依据的为振动相关仪器的检定规程,有8份（8.6%）依据的标准有误,包括依据的为其他仪器设备的检定规程或非检定校准规程,或参照了过期作废的检定规程。93家机构的手传振动测量仪器核查结果中,15.92 Hz、1 m/s² X、Y、Z 3个轴向的中位数（M）分别为0.976、0.978和0.971 m/s²,79.58 Hz、10 m/s² X、Y、Z 3个轴向的M分别为9.901、9.901和9.851 m/s²,159.20 Hz、10 m/s² X、Y、Z 3个轴向的M分别为9.931、9.933和9.884 m/s²。93家机构得分的M为18分,共78台仪器（83.9%）判定为合格,共15台仪器（16.1%）判定为不合格。非民营机构和民营机构测量仪器合格率比较,单轴测量模式仪器和三轴测量模式仪器合格率比较,差异均无统计学意义（均P>0.05）。结论广东省部分职业卫生技术服务机构手传振动测量结果准确性存疑,以稳定的标准振动源开展手传振动测量仪器核查可发现机构存在的问题。

Abstract: Objective To understand the performance of measuring instruments used by occupational hygiene technical service organizations engaged in hand-transmitted vibration measurement in workplaces in Guangdong Province. Methods In September 2023,a cluster sampling method was used to collect and analyze information on the latest calibration/verification certificates of 93 occupational hygiene technical service organizations engaged in hand-transmitted vibration measurement in workplaces in Guangdong Province,with one instrument each. Using SV111 portable vibration calibrator as the verification standard source,the error between the measured values and the standard values of the hand-transmitted vibration measuring instruments of each organizations was verified at three acceleration levels of 15.92 Hz,1 m/s²,79.58 Hz,10 m/s²,and 159.20 Hz,10 m/s². A score ≥11 points is considered qualified,with a maximum score of 18 points. Results The calibration or verification results of instruments from 93 institutions were all within the maximum allowable deviation range. However,out of 93 calibration or verification certificates issued by metrology institutions,85(91.4%) were based on the calibration regulations for vibration instruments,8(8.6%) were based on incorrect calibration regulations,including regulations for other instruments,non calibration regulations,expired and obsolete calibration regulations. In the instrument verification results of 93 institutions,the median(M) in the three axes(X,Y,Z) of 15.92 Hz,1 m/s² were 0.976,0.978,and 0.971 m/s²,respectively. The M values of 79.58 Hz,10 m/s² were 9.901,9.901,and 9.851 m/s²,respectively. The M values of 159.20 Hz,10 m/s² were 9.931,9.933,and 9.884 m/s²,respectively. The M score for 93 institutions was 18 points,with a total of 78 instruments(83.9%) judged as qualified and 15 instruments(16.1%) judged as unqualified. There were no statistically significant differences in the qualification rate of measuring instruments between non private organizations and private organizations,as well as between single axis measuring mode instruments and three-axis measuring mode instruments(all P>0.05). Conclusion The accuracy of hand transmitted vibration measurement results in some occupational health technical service organizations in Guangdong Province is questionable,and conducting hand transmitted vibration measurement instrument verification using a stable standard vibration source can reveal issues within the organization.
