What are the provisions of the inspection and testing agency on whether the testing equipment needs

Standard provisions. In order to understand the status of the instrument, to maintain the reliability of the calibration status of the instrument during the two calibrations, and to reduce the deviation of the results due to changes in the stability of the instrument, it is necessary to check it, in addition to checking the instrument before and after the shutdown, the important testing equipment needs to be checked during the two cycles of verification (calibration). Finally, it meets the requirements of monitoring work and ensures the quality of monitoring results.

Understand whether the precision, accuracy and sensitivity of the instrument have changed, and also make a conclusion about the work done from the last verification to this verification, if there is a problem with the instrument in the future, there is no need to verify the results before this verification.

When the regulatory department supervises, in addition to checking the software and hardware configuration of your laboratory environment and the ability of the inspector, the most important thing is to see whether your equipment has been verified. The verification is carried out regularly by the metrology and testing institutions of the quality supervision department.

Then look at your reagent configuration and usage, inspection records, sample retention, etc.

Laboratories generally carry out regular verification or calibration of instruments to ensure the traceability of their measurements, and carry out necessary maintenance and maintenance to ensure the effectiveness and reliability of the equipment. Therefore, most laboratories believe that as long as the instrument is regularly verified or calibrated, the instrument is reliable and the data produced is valid.

First of all, it is necessary to clarify what the testing requirements are, and then we can know whether the instrument and equipment can be met. The testing requirements should be based on national standards, or may be the needs of users.

Hello, dear, very happy with your question, how should the inspection and testing institutions carry out the period verification of instruments and equipment, and help you find out how the inspection and testing institutions should conduct the period verification of instruments and equipment: (1) Verification of the use of reference materials. Reference materials include various standard samples and physical standards.

When using reference materials for verification, it should be noted that the value of the reference materials used can be traced back and within the validity period. For example, pH meter, ion meter, conductivity meter, etc. are verified by fixed-value solution, gas detector is verified by standard gas, and standard flowmeter is used for gas sampler. When using reference materials for verification, it should be noted that the value of the reference materials used is traceable and valid.

Hope mine can help you. Wishing you good health and a happy mood!

Kiss. Lu San (2) uses the instrument to set up an air tomb for verification. Some instruments come with their own calibration equipment, and some also have an automatic calibration system that can be used for verification.

Electronic balances, for example, often come with a calibration weight. (3) Participate in inter-laboratory comparisons. and (4) comparison with the magnitude of another device or devices of the same accuracy class.

Kiss. (5) Re-test the amount of the retained sample: the performance of the retained sample (the value of the test) is stable, and it can only be used as a verification standard for the period of verification. (6) In the case of Qiaoqing where resources permit, high-grade instruments and equipment are used for verification.

Kiss. Verification results: The inspection situation during the period should be recorded and archived.

When it is found that there is a problem with the operation of the equipment during the inspection, it should be stopped for repair. When there is an impact on the validity of the test results involved in the operation of the equipment with problems in the operation of Luxian, the test items should be re-tested. Basic Requirements:

1) Use reference materials and standard samples for permeation for determination, and the error should not exceed 2 3 of the allowable difference. (2) Re-test the samples suitable for retention, compare the test results, and the deviation should not exceed the multiple of the parallel tolerances specified in the relevant testing method standards. (3) Conduct comparison experiments with other laboratories.

The deviation shall not exceed 2 times the parallel tolerance specified in the standard of the test method.

Summary. The inspection and testing institution shall establish and maintain the internal audit procedures of the management system in order to verify whether its operation meets the requirements of the management system and this Code, and whether the management system is effectively implemented and maintained. The internal audit is usually conducted once a year, and the person in charge of quality plans the internal audit and formulates the audit plan.

Internal auditors must be trained and qualified, and internal auditors should be independent of the activities being audited.

What should be audited by the inspection and testing organization to confirm its operation.

Hello, I am the special guest professional respondent of the change: Linda teacher <>

I've seen your message and I'm sorting out the answers, and I'll reply to your <> within 3 to 5 minutes

The review of instruments and equipment is mainly to review the validity of the traceability results of the value.

Instruments and equipment refer to the instruments or devices used in science and technology for experiments, measurements, observations, inspections, drawings, etc. It is usually a set of equipment or machines prepared for a specific purpose. Equipment or devices that are generally used for scientific research or technical measurement, industrial automation, process control, keying, production, etc., are generally dedicated to one purpose.

Capital items refer to industrial products used by industrial buyers in the process of production and operation, including fixed equipment and auxiliary equipment. Fixed equipment includes all buildings (factories, offices), fixed equipment is the main equipment, and the purchase or construction process goes through a long decision-making process.

1. According to the purpose and purpose of use.

There are mainly measuring instruments, automobile instruments, ionizing radiation instruments, tractor instruments, marine instruments, aviation instruments, guiding the old and the dead, driving instruments, radio testing instruments, building materials testing instruments, first-class testing instruments, geodetic surveying and mapping instruments, etc.

Second, according to the machinery industry products of the instrumentation to divide.

There are 13 categories of industrial automation instruments, electrical instruments, optical instruments, analytical instruments, laboratory instruments and devices, material testing machines, meteorological and marine instruments, film machinery, photographic machinery, photocopying micromachinery, instrumentation components, etc.

Hello dear! We are happy to answer for you: how should inspection and testing institutions confirm the instruments and equipment after measurement traceability? Answer: Hello <> you are buried

When using an external calibration service, a calibration service from a laboratory that can demonstrate qualification, measurement competence and traceability should be used to guarantee the traceability of the measurement. The calibration certificate issued by the laboratories shall include the measurement results with the measurement uncertainty and/or the declaration of compliance with the established metrological specifications (see the above requirements: first, the laboratory should select a qualified verification and calibration laboratory qualification.

The verification certificate issued by the verification laboratory shall have the authorization certificate number of the authorized legal metrology institution. The calibration certificate issued by the calibration laboratory shall bear the laboratory accreditation mark Note 1: A calibration laboratory that meets the requirements of this criterion is considered to be qualified.

A calibration certificate issued by a calibration laboratory accredited in accordance with this Code with the mark of an accredited body is sufficient evidence of the traceability of the reported calibration data for the calibration in question. Secondly, look at the accreditation scope of the verification and calibration laboratory, and help you verify and calibrate the items that are not within the scope of the verification and calibration laboratory. Third, look at what standards (instruments) are used in the results report of the verification and calibration laboratories to calibrate the instruments and equipment of your laboratory, and the certificate number and validity period of the standards.

There is no measurement uncertainty given. The verification laboratory can know the error range from the verification procedure, and then the measurement uncertainty can be calculated. The calibration laboratory only gives calibration data and measurement uncertainty.

It is up to the laboratory to make its own judgment whether to meet the needs of the laboratory. Therefore, it is even more necessary for the laboratory to confirm it by itself.

Dear, the results you get here: when the inspection agency conducts testing, the main testing standards can be divided into the following categories: 1

National standards: National standards are standards formulated by the General Administration of Quality Supervision, Inspection and Quarantine or other relevant national institutions to standardize the quality, safety, environmental protection and other requirements of various products, services and processes. 2.

Industry standards: Industry standards are standards formulated by relevant industry associations or organizations to standardize the quality, safety, and environmental protection requirements of products, services, and processes in a specific industry. 3.

International standards: International standards are standards formulated by international organizations such as the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), and the International Telecommunication Union (ITU) to standardize the quality, safety, and environmental protection requirements of products, services, and processes worldwide. 4.

Local standards: Local standards are standards formulated by local standards or relevant departments to standardize the quality, safety, environmental protection and other aspects of products, services and processes within a certain local scope. 5.

Enterprise standard: Enterprise standard is a standard independently formulated by the enterprise group, which is used to standardize the quality, safety, environmental protection and other aspects of its own products, services and processes. Different inspection agencies and different testing items may be based on different standards, and the specific standards for testing need to be determined on a case-by-case basis.

"Evaluation Criteria for Qualification Accreditation of Inspection and Testing Institutions" (2016 official version).

The inspection and testing institution shall confirm the ability of the personnel who take samples, operate equipment, inspect and test, issue inspection and testing reports or certificates, and put forward opinions and explanations according to the corresponding education, training, skills and experience, and take up their posts with certificates. Personnel who are familiar with the purpose, procedures, methods and results evaluation of inspection and testing should supervise the inspection and testing personnel, including intern employees.
