Class 1 and Class 2 A.C. static direct connected watt hour smart meters are advanced measurement tools used for invoicing and monitoring in the energy industry. Because these smart meters are directly linked to the electrical circuit, they can measure active power use (measured in watt-hours) with extreme accuracy. The main distinction between Class 1 and Class 2 meters is their accuracy, with Class 1 offering the highest level of precision and Class 2 offering a somewhat lesser one. Class 1 meters are frequently utilized in commercial and industrial settings where accurate invoicing and monitoring of power consumption are crucial. Class 2 meters are typically used in residential settings where billing accuracy is crucial but not as vital as in larger-scale applications. Although slightly less precise than Class 1 meters, they nonetheless provide trustworthy measurements.
The Indian Standard IS 16444 (Part 1):2015 lays out the specifications for A.C. static direct-connected watt-hour smart meters with Class 1 and Class 2 accuracy. Adherence to IS 16444 (Part 1):2015 facilitates the production of meters by manufacturers that fulfill the required accuracy classifications (Class 1 and Class 2) and have accurate measuring capabilities. By adhering to these standards, meters are guaranteed to meet the communication protocols and data formats necessary for interoperability, which promotes effective grid management and data exchange. Producers that follow these guidelines make sure their goods meet legal requirements, which lowers the possibility of legal problems and liabilities.
Note: The obligatory ISI Mark Certification must be obtained by manufacturers of A.C. static direct-connected watt-hour smart meters, including Class 1 and 2.
These sophisticated electrical measuring instruments are critical for monitoring and invoicing power use in a variety of contexts, and their accuracy, dependability, and performance are greatly enhanced by ISI certification. It means that these meters have passed strict testing and meet the strict standards established by the BIS, which are meant to assess their accuracy, robustness, and usability. These meters are appropriate for use in both residential and commercial power monitoring applications since their accreditation guarantees that they adhere to the necessary criteria for accuracy and data reporting.
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

There are two approaches for Indian manufacturers to become certified with the ISI Mark:
Regular Procedure
With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.
Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards
Step 2: Submission of the Application Form

Simplified Procedure
This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.
Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard
Step 2: Sample Testing
