No most reliable, only with or without meeting the requirements.
鈪 Our company is a third-party testing organizations, want to apply for metrological calibration, to take what process
Surely not, to do a third-party calibration institutions must have CNAS qualifications, CMA is only the local metrology institute's endorsement, not authoritative, limited to internal calibration
Ⅲ measurement of the qualifications of the staff who need to have a calibration
To do instrumental Calibration needs to be calibrated according to the level of the instrument, to the appropriate measurement of the Bureau (local or higher level) declaration, measurement of the Bureau will use the standard instrumentation, and workers to assess the qualifications issued to the unit after passing the qualification certificate, and the operator's license.
Ⅳ General company instruments need to calibrate the company's what department is responsible for going to calibrate
certainly is the measurement of the calibration department, copy, but the general company does not have this department, the establishment of this department need to invest too much manpower and material resources, so a lot of companies to do the calibration of the instrument is entrusted to a third-party calibration organization, time and effort but also to save money, of course, looking for a third-party calibration agency must be If you are the kind of calibration qualification ---- I am Kunshan Avert metrology, very happy to answer for you
Ⅳ Ⅳ enterprise themselves on the calibration of measuring instruments to what conditions
First, the necessary conditions for calibration or verification of measuring instruments
Enterprises and public institutions in the scientific research, production and service provision, especially in the inspection and testing process, to be used to a large number of measuring instruments, such as special calipers, micrometers, dial gauges, micrometers and so on, and so on. Calipers, micrometers, micrometers; production process feeding scales, process monitoring monitors, pressure vessels, pressure pipelines on the pressure gauge, flow meter, finished product testing to power meter; production and inspection **** with measuring instruments as well as equipped with belonging to the mandatory verification of measuring instruments and computer software and so on. In accordance with GJB9001A-2001 standard 7.6 provisions of two requirements: First, the measuring instruments are used in the monitoring and measurement process equipment; Second, the measuring instruments to monitor and measure the results of the product (or service) in line with the identified requirements to provide evidence. At the same time to meet the above two conditions, the need for calibration or verification.
Second, the difference between calibration or verification of measuring instruments
"Calibration" and "verification" is to ensure the accuracy of the value of two different ways and means. Calibration and verification from the traceability, they are the same, but from the legal effect, they are different. GJB9001A-2001 standard 7.6 clause a) requirements: against the traceability of international or national standards of measurement standards, if necessary, measuring equipment should be in accordance with the specified time interval or before use for calibration or verification. The word "or" in the standard establishes a parallel and optional relationship between calibration and verification. Under the premise of meeting the laws and regulations, enterprises and institutions can choose their own methods of verification or calibration for different situations.
Calibration is a voluntary traceability behavior of the enterprise, not mandatory, the enterprise can be calibrated on their own, but also can be entrusted to an external agency for calibration. The result of calibration is a calibration certificate or calibration report, the report does not judge the qualification of measuring instruments, generally is not a technical document with legal effect. The verification belongs to the national mandatory law enforcement behavior, the results of the verification must be sent to the measurement of measuring instruments, instruments and equipment to make qualified or not, when the results are qualified, the certificate will be issued to the verification, unqualified will be issued to the unqualified notice, the results of the verification has the force of law.
Belongs to the mandatory verification of measuring instruments must meet two conditions: First, the instrument is included in the national mandatory verification of the work of the meter directory; Second, the measuring instruments must be used for trade settlements, safety and security, medical and health care, environmental testing for specific purposes. Used for trade settlement, safety and protection, medical and health, environmental testing purposes other than measuring instruments, such as scientific research, production, business management with measuring instruments, generally available in accordance with the non-compulsory verification of measuring instruments for management and control.
Ⅵ measuring instruments which need to be calibrated which only need to be calibrated on it
Measuring Instruments state copy of the mandatory inspection of the catalog of measuring instruments, if used for trade settlements, safety and security, medical and health care, environmental monitoring, and if used as a measurement standard, these must be mandatory calibration;
industry standards rarely require mandatory calibration; in addition, can be calibrated; of course, can be calibrated; of course, in accordance with the non-mandatory management and control of measuring instruments, such as scientific research, production, management and management.
Ⅶ Measurement testing/calibration laboratory to establish what conditions
China's measurement of the 1980s when the law was promulgated, there is no "measurement of calibration", only "measurement of calibration", within the State General Administration of Quality Supervision, Inspection and Quarantine, and therefore, the State Administration of Quality Supervision, Inspection and Quarantine. March 19, 1999 issued a "non-compulsory inspection of measuring instruments used by enterprises by the law of independent management of the announcement" stipulates that: enterprises to use "non-compulsory inspection of measuring instruments of the verification cycle
Ⅷ calibration of measuring instruments instruments need to be what qualifications
China's measurement of the 1980s when the law was promulgated by the country has no "Measurement calibration" that only "measurement verification", so the State Administration of Quality Supervision issued on March 19, 1999 "on the use of non-compulsory inspection of measuring instruments by the enterprise according to law, the independent management of the announcement" stipulates that: "Non-compulsory inspection of measuring instruments used by the enterprise "non-compulsory calibration of measuring instruments verification cycle, by the enterprise according to the actual use of measuring instruments, in line with the principles of science, economy and accuracy of the value of their own determination. Non-compulsory verification of measuring instruments by the enterprise according to the needs of production and scientific research, you can decide on their own in the unit verification or sent to other metrological verification institutions verification, testing, any unit shall not interfere."
The so-called non-compulsory calibration of measuring instruments, including the internal production process control, quality inspection and other measurement equipment, these measurement equipment for verification or testing (can be understood as the current calibration), sent outside the inspection / school or internal inspection / school, inspection / school cycle, are "by the enterprise according to law, independent management ", "self-defined" and "self-determination", "any unit shall not interfere". On the measurement standard assessment of the specification is required to "enterprises and institutions of the highest standard of measurement" must be built and accept the assessment, for internal calibration similar to the standard of measurement of "measuring equipment" does not require mandatory construction and acceptance of the standard of measurement assessment.
"Zhejiang Provincial Measurement Management Regulations" provides that the community to provide metrological verification and metrological calibration services should be built and accept the measurement of standard assessment is reasonable, because some of the community to carry out verification/calibration services using measuring equipment means that it becomes a "social public standard of measurement, the social public standard of measurement must be subject to the assessment of the measurement of standards. The "regulations" provide that "enterprises and institutions" can establish the unit to use the measurement standard for internal calibration "only in accordance with the provisions of the Measurement Law," the highest measurement standard should be measured by the measurement The competent authorities to assess the qualification", which are reasonable and legal. As long as enterprises and institutions, although the internal calibration but not the establishment of "the highest measurement standard of enterprises and institutions", of course, is not mandatory to accept the measurement standard assessment. However, the internal calibration of the use of measuring equipment must be traceable to the statutory measurement of technical institutions, which is to ensure the traceability of the bottom line. Because in those days there is no domestic "calibration" term, testing, inspection, comparison, experiment, laboratory, calibration, verification, etc. are actually "measurement" of a kind, only verification is specifically for measuring instruments measurement activities, calibration can be for the measurement of equipment measurement activities, can be Calibration can be for the measurement of equipment measurement activities, can also be for the measurement of product activities, the rest are for the product (measurement equipment manufacturing process is considered to be the product before leaving the factory) of the measurement activities. Therefore, at that time, the proposed "test" of measuring instruments can be understood as "calibration".
Currently, with the term "calibration", generally for the measurement of in-use measuring equipment measurement activities will no longer use the "test" and use "calibration". If the manufacturing process of measuring equipment for measurement, should still use the "test", "inspection", do not use "calibration". Homemade special gauges in the manufacturing process should be issued test reports rather than calibration certificates, once put into use, from the first measurement confirmation, including future periodic measurement confirmation, should be issued "calibration report", measurement confirmation by the measurement confirmation staff based on the results of the calibration results and the measurement process of the measurement requirements for the comparison of the results of the measurement confirmation, issued by the Measurement confirmation mark.
According to the current rules, the CNAS qualification can be oriented to the community to carry out calibration business, which belongs to the supply and demand side of the business contract within the matter, a willingness to fight a willing, as long as the willing party willing to do so on no problem.
According to the regulations to provide verification/calibration services to the community must be *** measurement of the administrative departments based on JJF1069 assessment of qualified statutory measurement of technical institutions or authorized measurement of technical institutions. Only obtained CNAS accreditation can only prove that the laboratory's calibration capabilities, if the non-statutory measurement of technical institutions or non-authorized measurement of technical institutions to provide measurement and calibration services to the community "is not permitted", refers to the calibration of the two sides of the act is not protected by measurement law. As a result of the dispute is not protected by the measurement law, then how to resolve such disputes? Should be based on the contract law and consumer protection law, should be depending on who violated the contract, whether the service provider to provide defective services for adjudication.
"Mutual trust between the two sides, there is a contract, that is, there is no CNAS qualification is also possible", if "the contract stipulates that the service of Party B shall obtain the CNAS qualification qualification, issued by the calibration certificate shall have the CNAS logo", then Party B If "the contract stipulates that the service provider shall obtain CNAS qualification and the calibration certificate shall have CNAS mark", then Party B provides the calibration certificate without CNAS mark, or issues the certificate with CNAS mark without being recognized by CNAS in fact, it is providing defective service and violating the provisions of the contract. Of course, Party A knows that Party B does not have CNAS accreditation, and for some purpose to voluntarily accept the counterfeiting behavior, but also should bear the legal responsibility for its violation.
In short, CNAS accreditation is a third-party notary's recognition of competence, not qualification recognition. Only with proof of accreditation can you be protected by the relevant laws. Without accreditation, but with proof of competency, you can be trusted by your customers and have a higher level of security. Neither the qualification recognition nor the ability to recognize the party must trust it, that is the power of the party, but all the adverse consequences arising from the party to assume the same responsibility it should bear.
Ⅸ There is no certified company to do metrological calibration services ah
Fangyuan testing and certification is a certified company can do the work of metrological calibration, everyone said it is very good.
Ⅹ measuring equipment calibration cycle is mandatory, the enterprise can arrange their own
The national measurement of calibration review of the enterprise measuring equipment system calibration cycle for the absence of mandatory cycle, you can arrange their own, the general calibration of measuring instruments within the enterprise is recommended for 1-2 years.
With reference to JJF 1139-2005 "Principles and basic methods for determining the calibration cycle of measuring instruments", the calibration cycle is generally determined by a fixed step adjustment method, incremental response adjustment method, interval testing method, maximum likelihood estimation method, but also with reference to the management chart method or verification of the standard method, a comprehensive weighted scoring method.
