Analysis on the methods of quality control of construction hoisting equipment testing

first, strengthen the management of the elements of the quality management system of the testing organization

among the elements of the quality management system of the testing organization, management commitment, quality policy, quality objectives, post responsibilities and management review are closely related to whether the testing activities are carried out normally, which is the premise and foundation to ensure the effectiveness of the testing activities. As an intermediary service industry, if testing institutions can consciously establish quality objectives, strictly fulfill management commitments, urge employees to perform their job responsibilities and regularly carry out management reviews in their business activities, they will also promote the improvement and continuous improvement of human resources, testing instruments and equipment, environmental conditions and other testing management elements, so as to promote the effective operation of testing quality control system and improve the level of testing safety technical services

(I) fulfill management commitments: the first person in the inspection and testing institution, that is, the top management, should perform the following management responsibilities and relevant job activities to reflect that its testing services meet the needs of the safety of lifting machinery and equipment:

1. Carefully publicize and implement national laws, regulations, technical specifications and relevant management regulations, Urge all testing personnel to strictly perform the testing technical procedures:

2. Formulate the quality policy and quality objectives of the testing organization, establish the quality management system, and ensure its effective operation and continuous improvement

3. implement management review as required

4. The top management should take enhancing the satisfaction of the safety supervision department and the use unit of hoisting machinery and equipment as the management goal, and take ensuring the safety of hoisting machinery and equipment as the purpose, and bear legal responsibility for its test results and appraisal conclusions

(II) testing institutions should formulate quality policies and quality objectives to ensure the seriousness and scientificity of testing work:

1. Quality policies: quality policies formulated and implemented by testing institutions, such as "law-abiding, integrity, science and justice", in order to promote that all testing tasks they undertake must be based on national, industrial or local technical standards, adopt correct testing methods, and obtain accurate testing results, Make clear test conclusions. In the process of performing their duties, they will not be affected by any interference, and maintain the impartiality of the testing work

2. Quality objectives: formulate short-term and long-term management objectives from the aspect of enterprise operation and management, so as to achieve scientific management of testing work, excellent equipment, excellent testing and high-quality service, and better control the conclusive error rate of testing report and the complaint rate of all parties in society

(III) clarify the responsibilities, authorities and communication of the staff of the testing institution

1. responsibilities and authorities: the top management stipulates the responsibilities, authorities and interrelationships of all management personnel, inspection and testing personnel and personnel in key positions that have an impact on the testing quality; Equip the technical director, and specify the clear responsibilities and powers to be fully responsible for the technical operation of the testing organization: equip the quality director, and specify the clear responsibilities and powers to ensure that the quality management system is implemented and maintained, and there should be a direct channel to report the performance of the quality management system and any improvement needs to the top management

2. internal communication: the top management should establish effective communication channels between all levels and functions in the inspection and testing organization to ensure the information of relevant regulations, technical specifications and standards; Government and customer request information. The forms of communication can be diverse, such as regular quality and safety meetings, briefings, announcements, internal publications, couplets, etc

(IV) regularly carry out management review:

the top management should regularly review the quality management system and testing activities according to the predetermined time interval and procedures to ensure their continuous suitability, sufficiency and effectiveness. Management review is usually conducted once a year. Records of problems found in the management review and the measures taken therefrom shall be maintained

1. The input of management review should include:

(1) the suitability of quality policies and objectives and the applicability of system documents:

(2) the opinions and requirements of the industry safety supervision department and the degree of compliance with the requirements of regulations and technical specifications:

(3) the results of recent audits (internal and external audits)

(4) customer feedback and complaints

(5) work performance and quality of inspection and testing services

(6) status of preventive and corrective measures

(7) tracking measures of previous management reviews

(8) may affect the change of quality management system due to functional characteristics

(9. Manual switch should be installed on the wire to control the experimental motor source) suggestions for improvement

(1o) management report

(11) other relevant information

2. Review output: the output of management review should include any decision on the effectiveness of the quality management system and its improvement measures: the improvement of inspection and testing related to industrial safety supervision and customer requirements; Resource requirements

(V) internal supervision of testing work of testing institutions: testing institutions should establish internal supervision to supervise the testing process and results. The number of supervisors is generally not less than 10% of the detection personnel, and the supervisors should be familiar with the detection methods and procedures. Have rich testing experience and professional technical knowledge, and can make a correct evaluation of the accuracy of testing results. Technicians who have been engaged in testing for more than 2 years are responsible for checking and supervising the correctness of relevant testing procedures, testing methods and testing results. In addition, they should also carry out daily supervision on the compliance of instruments, equipment and environmental conditions involved in testing. If any deviation is found, it has the right to put forward the notice of correction and rectification, and if necessary, it has the right to terminate the unapproved deviation detection activities. At the same time, the testing institutions should regularly organize and carry out regular supervision, regular review of inspection and testing rules, inspection and testing plans, instrument and equipment operating procedures and other operation guidance documents, internal quality control charts using statistical technology, comparison between participating inspection and testing institutions or capacity verification plans, etc

II. Key points of quality control of lifting machinery and equipment testing institutions

in view of the fact that the quality management system of some inspection and testing institutions is like a sham, selling qualifications, affiliated testing, not implementing inspection and testing in accordance with the operation instructions or operating procedures, and even making false reports, in the daily quality control of testing institutions, The main contents are as follows:

(I) business behavior

1. Check whether the business is beyond the scope of qualification approval or authorization

2. Whether to sign the test entrustment agreement and contract, and whether the use unit of lifting machinery and equipment will sign the test agreement and contract as the entrusting party

3. Whether the construction and supervision units are invited to witness the inspection work during the on-site inspection, and fill in the corresponding witness records

(II) technical preparation for testing

1. Whether corresponding testing "operation instructions" or "testing implementation rules" have been prepared; Whether the operation instructions meet the requirements of laws and regulations and safety technical specifications

2. For the test items that are difficult to test, whether the test plan has been prepared and whether the test plan has been produced through strict technical approval procedures

3. Whether the original records are formatted and specified in the "operation instructions"

4. Whether there is a corresponding relationship between the original record and the content of the test report, and the content of the original record should not be less than the content of the report

5. Whether the test report is formatted and meets the requirements of the corresponding safety test technical regulations

6. Whether the test items of the report are set according to the requirements of the procedure, and whether the test report has a corresponding relationship with the content of the original record

(III) allocation of testing resources

1. Whether the instruments, equipment and tools related to testing are complete:

2. Whether the testing instruments and equipment have verification marks and intact status marks:

3. Whether the testing instruments and equipment are verified or calibrated according to the regulations, and whether there are verification or calibration records within the period of validity

4. Whether the testing personnel have received professional training and work with certificates:

5. Whether the allocation of testing personnel is compatible with the testing workload

(IV) implementation process of inspection

1. Whether the inspector wears necessary labor protection articles. Whether the inspection operation violates the safety operation regulations:

2. Whether the inspectors inspect according to the inspection procedures specified in the "operation instructions" or "inspection plan"

3. whether the test operation is skilled:
