Scheme Of Inspection And Testing 1. LABORATORY - A laboratory shall be maintained which shall be suitably equipped (as per the requirement given in column 2 of Table 1) and staffed, where different tests given in the specification shall be carried out in accordance with the methods given in the specification. 1.1 The manufacturer shall prepare a calibration plan for the test equipment. 2. TEST RECORDS – The manufacturer shall maintain test records for the tests carried out to establish conformity. 3. LABELLING AND MARKING – As per the requirements of IS 2082:2018. In addition, the water heaters shall also be marked with an identification in code or otherwise for traceability. Each water heater shall be provided with the instruction manual for installation, operation and use, routine maintenance and safety precautions. This shall also include values declared by the manufacturer in respect of relevant test requirements. The manual shall also specify the critical components and supply the circuit diagram to ensure proper replacement of components for each class (Cl. 6 of IS 2082:2018) at the time of servicing. 4. CONTROL UNIT – All stationary storage type electric water heaters of the same class,

design, rated capacity and rated voltage manufactured in a week or 500 stationary storage type electric water heaters of same class, design, rated capacity and rated voltage manufactured within a week, whichever is less, shall constitute a control unit. 5. LEVELS OF CONTROL - The tests as indicated in column 1 of Table 1 and the levels of control in column 3 of Table 1, shall be carried out on the whole production of the factory which is covered by this plan and appropriate records maintained in accordance with paragraph 2 above. 6. REJECTIONS – Disposal of non-conforming product shall be done in such a way so as to ensure that there is no violation of provisions of BIS Act, 2016.
