How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Report qualification: CNAS, CMA, CAL, etc
. Presentation style: electronic
version of the testing cycle: 3-15 working days (expedited can be expedited)
Testing cost: Quotation according to customer needs and experimental complexity
Sample size: Choose to send samples or visit the door according to the sample size
Scope
This standard is only applicable to newly manufactured static active energy meters (hereinafter referred to as instruments) with accuracy levels 1 and 2 for measuring AC active energy in the frequency range of 45 Hz to 65 Hz and their type tests This standard only applies to static active energy meters for indoor and outdoor use consisting of measuring elements and one or more registers installed in the same case. It is also applicable to one or more work indicators and one or more test outputs
This standard does not apply to:
a) active energy meters with terminal voltage exceeding 600V (line to line voltage for multiphase instruments) B) Portable instrument C) The data interface of the instrument register If the display and/or storage device is externally connected, or if other devices (such as maximum demand indicators, telemetry devices, time switches, or remote controllers) are included in the table, this standard only applies to the metering section This standard does not include acceptance testing and consistency testing, and the basic guidelines for acceptance testing are provided in GB/T17442 The reliability requirements are also not included in this standard, as there is no suitable accelerated testing method for accepting type test documents to verify this requirement
