电动抗折试验机是用于测定水泥胶砂长方体试件抗折强度的试验机。根据《JJG476-86电动抗折试验机检定规程》要求,对示值检定就是对应力值检定,从而保证抗折强度的准确性。但在电动抗折试验机力值改为法定计量单位的过程中,有少数单位购买了没有力值(N)刻度只有强度(MPa) 刻度的标尺而进行了力值改制,从而给计量部门对电动抗折试验机检定造成困难。据了解,多数计量部门遇此情况因无法检定而拒绝检定,少数计量部门找出力值
Electric bending test machine is used to determine the flexural strength of cement mortar cuboid test machine. According to “JJG476-86 electric flexural testing machine test procedures” requirements, the value of the test is to verify the value of stress, so as to ensure the accuracy of the flexural strength. However, in the process of changing the test value of electric flexural test to the legal unit of measure, a few units purchased the scale with no force (N) scale and only strength (MPa) scale, Electric bending testing machine caused difficulties. It is understood that most of the measurement department in case of failure to test the situation and refused to test, a small number of measurement departments to find value
