"The calibration agency has already put a green calibration label on our instrument, do we need to put our company's green certificate label? "Recently, many customers have been asked about this problem. For this problem, Xiaobian believes that this is a manifestation of the concept and use of these two labels.

First, the calibration certificate issued by the calibration institution contains the name of the calibration institution, the calibration certificate number, the calibration date and the name of the calibrator, etc., through the calibration label, you can intuitively understand the date of the next calibration. Second, the certificate issued by the enterprise itself includes the name of the equipment, equipment number, manufacturer, equipment model, factory number, purchase date, etc., some also include authorized users, maintenance engineers and telephones, etc., which is equivalent to the ID card of the equipment, the main purpose is to facilitate equipment identification and better equipment management. Because the purpose of these two labels is different, and both are essential, so that even if the calibration mechanism is affixed with the calibration label, the enterprise still needs to attach the equipment label for better management of the equipment. Here it is noted that enterprises often attach the "equipment label "," certificate "and" calibration label "to the calibration institution confused, so the calibration institution is required to issue a" certificate ", in fact, the "certificate" is divided into two kinds: one is the factory "certificate" this certificate is to show that the product quality meets the relevant national standards, to achieve the conditions of sales in the market; One is the verification or testing "certificate" that is, after the verification or testing, the data measured by the instrument and equipment meet the national requirements, so the verification or testing certificate is issued. "Calibration label" belongs to the scope of calibration and does not have the right to judge whether the calibration data is qualified or not, so it is unreasonable and non-compliant for the enterprise to require the calibration institution to issue a "certificate of qualification". So, can companies attach a "certificate" to their equipment? This is actually allowed as a measure of internal management of the device, as long as it is not external, internal operation is fine. Although the "calibration label" can not conclude whether the calibration result of the instrument and equipment is qualified or not, the enterprise can judge whether the instrument and equipment are in the "tolerance range" according to the calibration data, so as to make a conclusion whether the internal equipment is qualified or not, paste the "certificate" on the qualified instrument and equipment, and paste the poor but still can continue to use the unqualified instrument and equipment respectively Yellow label (for permitted use) and red label (for disabled use).
