| X3741. By/Mtn. from EFC. EFC2/AD30.4.30. X.3741. SYRINGE TYPE HYDROMETERS FOR PRODUCTION CHASSIS. May we please refer you to our EFC10/T8.3.28 and our EFC2/AD5.11.29. We selected one of the above instruments as a semi standard and suggested the use of this for checking hydrometers as supplied. It was suggested that we should check this semi standard periodically against our floating standards. We should be pleased to know how this matter stands as we have heard nothing from you in this connection. EFC. | ||
