Why we need to have our own laboratory
As a meter manufacturer, CLOU has its own laboratory.
The main purpose of energy meters is for billing and payment. CLOU electronic energy meters are accurate, so there is evidence for utilities and their customers.
The energy meters are devices for measurement. Meters have type test reports that are proving meters meet the relevant standards.
CLOU meters have certifications like IEC, MID, DLMS and IDIS. It usually takes several weeks testing time for external institutes to get the certifications.
Our laboratory can perform the same test items. So, before we send meters to an external type test laboratory, we can already be sure that we pass the tests.
Our Energy Meter Laboratory
Set up in 2006 and with a size of 1,500 square meters, CLOU laboratory meets the CNAS (China National Accreditation Service for Conformity Assessment) standards, like CNAS CL01:2018 IDT, CNAS CL01-A003: 2019 and CNAS CL01-A008: 2018 as well as ISO 17025:2017.
The CLOU electronic energy meter test laboratory moved to CLOU headquarter building in 2014.
CLOU Accuracy Testing Room
The accuracy testing room covers an area of 160 square meters. It mainly completes the accuracy, response and consistency of meters and has the test ability to complete the relevant test items of electric energy meters specified in GB/T 17215 and IEC 62053 standards.
Among them, several test items like basic error test apply for national CNAS laboratory certification.
CLOU Electric Testing Room
The electrical testing room covers an area of 150 square meters, mainly completing a number of electrical testing projects such as AC voltage and current external magnetic field induction.
It meets the relevant requirements for meter testing specified in GB/T 17215 and
IEC 62053 standards.
Beside of extensive environmental tests, nine test items such as AC voltage test and power consumption test apply for national CNAS laboratory certification.
Environmental Testing Room
The environmental testing room covers an area of 260 square meters.
It mainly completes the environmental testing projects such as high and low temperature, alternating damp heat, ingress protection and solar radiation of the products of all business divisions of CLOU company.
It meets the experimental requirements of GB 2423 standard and applies for national CNAS laboratory certification for three projects: high-temperature test, low-temperature test and alternating damp heat test.
CLOU Parts Testing Room
The parts testing room covers an area of 140 square meters.
The testing room mainly completes the mechanical testing items such as vibration and impact of the products of each business division.
CLOU Electromagnetic Compatibility Testing Room
The electromagnetic compatibility room covers an area of 135 square meters.
It mainly completes eight EMC test items: static electricity, pulse group, surge, conducted disturbance, attenuated oscillation wave, damped oscillation magnetic field, power frequency magnetic field and voltage sag, which meet the requirements of GB/T 17626 and IEC 61000 electromagnetic compatibility standards.
Among them, three items including static electricity, pulse group and surge apply for national CNAS laboratory certification.
Several devices in the electromagnetic compatibility testing laboratory are shown as below.
Beside of the routine tests in the factory, meter type testing is an essential item to guarantee the product quality. We are doing additional type tests also during batch production.
