2) the compulsory verification shall be carried out by the legal metrological verification institution or authorized metrological verification institution designated by the metrological administrative department of the government.
measuring instruments, measuring benchmark instruments and measuring standard instruments 1 Characteristics of measuring instruments measuring instruments have four characteristics: accuracy, uniformity, traceability and legality.
（1） Classification of metrological verification 1 According to the purpose and nature of verification, metrological verification is divided into: first verification, subsequent verification, in-service verification, periodic verification and arbitration verification.
(4) For the change of power consumption by users, such as reducing the power consumption capacity agreed in the contract, temporarily replacing large capacity transformers, user suspension, user temporary change, user relocation, user meter transfer, user renaming or transfer, user household division and consolidation, user cancellation and change of power consumption category, they should also apply in advance, bring relevant supporting documents, go to the power supply enterprise’s power consumption business place to handle procedures and change the power supply contract.
No unit or individual is allowed to use measuring instruments without verification seal or certificate, or beyond the verification cycle and unqualified after verification.
The units and individuals using the measuring instruments subject to compulsory verification must apply for verification in accordance with the regulations.
Sealing up: the use is suspended according to the utilization rate and production and operation conditions.
Forbidden: unqualified after verification or seriously damaged or damaged during use.
The main indicators to measure the quality and level of measuring instruments are their accuracy level, sensitivity, discrimination rate (resolution), stability, detachment and dynamic characteristics.
4) The scope of compulsory verification of measuring instruments includes: social public standards of measurement: the highest standards of measurement used by departments, enterprises and institutions; Working measuring instruments listed in the compulsory verification catalogue of measuring instruments for trade settlement, safety protection, medical and health, environmental monitoring, etc.
And truthfully fill in the power utilization application form and handle the necessary procedures according to the format specified by the power supply enterprise.
2.
3、 The measuring instruments of the project department are divided into three categories: A, B and C.
(1) First verification: the first verification of new measuring instruments that have not been verified.
5) Compulsory verification refers to the fixed verification relationship, fixed-point inspection, and fixed-point periodic verification.
(4) Periodic verification: the subsequent verification according to the specified time interval and procedure.
Most measuring instruments should be subject to subsequent verification after the first verification, and there are also some working measuring instruments subject to compulsory verification, such as bamboo and wood ruler.
Provisions on the use and management (1) measuring instruments are important tools for measuring and judging whether the quality meets the regulations in the project construction, which directly affects the project quality.
There are 122 days left before the examination time of the first construction.
(3) In use verification: the verification of the use state of control measuring instruments.
3) The verification cycle of compulsory verification shall be determined by the technical institution performing compulsory verification in accordance with the metrological verification regulations.
Applications for new installation, temporary power use, increase of power capacity, change of power use and termination of power use shall be handled in accordance with the prescribed procedures..
Have you read and asked questions today? Now learn from me the important knowledge points of Yijian Electromechanical Specialty! 1h431000 laws and regulations related to the construction of electromechanical engineering projects I.
2) Class B measuring instruments: caliper, feeler gauge, dial indicator, welding inspection ruler, measuring tape above 5m, thermometer, pressure gauge, multimeter, etc.
2.
1) class a measuring instruments, level gauge gauges, dial indicator gauges, megohmmeters and grounding resistance measuring instruments are listed as working measuring instruments in the national compulsory verification catalogue.
2、 Requirements for the use and management of measuring instruments 2.
(1) Characteristics of compulsory verification 1) compulsory verification is enforced by the metrological administrative department of the government.
Qualified: the accuracy that can meet the requirements of quality inspection, inspection and test after weekly inspection or one-time verification.
(5) The measuring instruments shall be marked with obvious signs such as “qualified”, “forbidden” and “sealed”, indicating the state of the measuring instruments.
According to the necessary procedures of verification and the form of legal management in China, metrological verification is divided into compulsory verification and non compulsory verification according to the necessary procedures of verification and the form of legal management in China.
3) Class C measuring instruments: steel ruler, wooden ruler, template, etc.
2.
1h431020 laws and regulations on construction power and construction 1h43102 regulations on engineering construction power I.
The project construction unit must apply in advance to the power supply business place of the power supply enterprise and go through the formalities in accordance with the relevant laws and regulations when it needs to install new power, temporarily power on, increase the power capacity, change the power consumption and terminate the power consumption.
(2) Subsequent verification: the verification of measuring instruments after the first verification, including mandatory periodic verification, verification after repair, periodic verification and verification within the validity period.
Dear students, the examination time of the first construction this year is November 5-6, 2022.
Application materials for power utilization in engineering construction (1) when applying for power utilization in construction projects, the power supply enterprise shall be provided with the documents approved by the power utilization project and relevant power utilization materials, mainly including: power utilization location, power utilization, power utilization nature, list of power utilization equipment, power load, security power, power utilization planning, etc.
Handling procedures for power use in engineering construction.
3.
（1） Basic provisions on the application of electricity for engineering construction 1 Application content of power for engineering construction application content of power for engineering construction mainly includes: review of power application, investigation of power supply conditions, determination and approval of power supply scheme, collection of relevant fees, verification of power receiving engineering design, construction intermediate inspection, completion inspection, signing of power supply contract (agreement), meter installation and power connection and other project businesses.
general assumptions for engineering construction power.
(5) Arbitration verification: metrological verification and testing activities for the purpose of adjudication.
