Currently NPL only offers AC Electrical Conductivity Standards with a stated accuracy of +/-0.7% of value.The Boeing standard BAC5651 calls for standards above 16.5MS/m to have an accuracy of +/- 0.12MS/m up to 60.5 MS/m (which at the extreme value is +/-0.2%).New Boeing and NIST calibrated standards are no longer available due to national public service cut backs.NPL have carried out a test under a M4R project (ref 10643) and shown that using the Van der Pauw Method they can achieve comparable accuracy but need more work to refine the measurement methodology and improved measuring equipment.The ability to provide UKAS compliant NPL DC Electrical Conductivity Standards would ensure ETher NDE's continuing growth in sales of this product.

目前NPL仅提供AC电导率标准，其规定精度为值的+/-0.7%。波音标准BAC 5651要求16.5MS/m以上的标准具有+/-0.12MS/m至60.5MS/m的精度（极端值为+/-0.2%）。由于国家公共服务削减，新的波音和NIST校准标准不再可用。NPL在M4 R项目下进行了测试（参考10643），并表明使用货车德堡方法，他们可以达到相当的精度，但需要更多的工作，以完善测量方法和改进的测量设备。提供UKAS符合NPL直流电导率标准的能力将确保ETher无损检测的持续增长，在销售该产品。
