Introduction<\/h1>\n

Hermetic Compressors are important components used in refrigeration and air-conditioning equipment. These compressors are designed with the motor and compressor mechanism enclosed within a gas-tight housing, making reliable construction, sealing, electrical safety and performance essential.<\/p>\n

In India, IS 10617:2018 \u2013 Hermetic Compressors \u2014 Specification (Second Revision)<\/strong> specifies safety and performance requirements for hermetic sealed type standalone motor-compressors operating on the vapour compression cycle. BIS currently lists IS 10617:2018<\/strong> under the compulsory product certification framework.<\/p>\n

The standard covers compressors suitable for low back pressure (LBP), commercial\/medium back pressure (CBP\/MBP) and high back pressure (HBP)<\/strong> applications and includes different compressor mechanisms such as reciprocating, rotary and scroll types.<\/p>\n

Qualitance India<\/strong> provides BIS Certification Consultancy for Hermetic Compressors as per IS 10617:2018, including product assessment, product grouping, documentation, laboratory testing coordination, BIS application assistance and factory inspection preparation.<\/p>\n

            \n

            Classification of Hermetic Compressors<\/h1>\n

            Hermetic Compressors under IS 10617:2018 are classified into categories based on their operating\/back-pressure application.<\/p>\n

            Low Back Pressure \u2013 LBP<\/h3>\n

            Generally associated with refrigeration and freezing applications.<\/p>\n

            Commercial Back Pressure \/ Medium Back Pressure \u2013 CBP\/MBP<\/h3>\n

            High Back Pressure \u2013 HBP<\/h3>\n

            Used for applications requiring higher evaporating-temperature operating conditions.<\/p>\n

            The BIS Product Manual uses LBP, CBP\/MBP and HBP<\/strong> categories for product grouping and licence scope.<\/p>\n

            \n

            Testing Requirements<\/h1>\n

            Testing is a major part of BIS Certification for Hermetic Compressors.<\/p>\n

            The BIS material for IS 10617:2018 identifies tests including:<\/p>\n

              \n
            • Compressor Capacity Rating Test<\/li>\n

              \n

              The BIS Product Manual notes that most tests can potentially be completed in a day, except the Locked Rotor Test<\/strong> and Resistance to Rusting Test<\/strong>, subject to the applicable testing arrangements.<\/p>\n

              \n

              Compressor Capacity Rating Test<\/h1>\n

              The compressor’s cooling capacity is evaluated under the specified test conditions.<\/p>\n

              Capacity testing is particularly important because the compressor needs to deliver the declared performance under the applicable operating conditions.<\/p>\n

              The BIS laboratory information currently lists separate testing charges according to cooling-capacity ranges, showing that capacity is an important part of the certification testing process.<\/p>\n

              \n

              Startability Test<\/h1>\n

              The startability test evaluates whether the compressor can start under the specified conditions.<\/p>\n

              This is important because refrigeration compressors may experience different pressure and electrical conditions during starting.<\/p>\n

              \n

              Locked Rotor Test<\/h1>\n

              The Locked Rotor Test evaluates the compressor under the applicable locked-rotor condition.<\/p>\n

              This is an important electrical and performance-related test under the standard.<\/p>\n

              \n

              High Voltage Test<\/h1>\n

              The High Voltage Test checks the electrical insulation system of the compressor to ensure that it can withstand the specified electrical stress.<\/p>\n

              \n

              Leakage Current Test<\/h1>\n

              The Leakage Current Test evaluates leakage current under the applicable test conditions.<\/p>\n

              This helps assess electrical safety of the compressor.<\/p>\n

              \n

              Pneumatic Test of Shell<\/h1>\n

              The compressor shell is tested under the specified pneumatic test conditions.<\/p>\n

              The purpose is to verify the integrity of the hermetically sealed housing.<\/p>\n

              \n

              Holding Charge Test<\/h1>\n

              The Holding Charge Test evaluates the compressor’s ability to maintain the specified holding charge without unacceptable leakage.<\/p>\n

              \n

              Bursting Test<\/h1>\n

              The Bursting Test evaluates the pressure strength of the compressor shell and helps assess its ability to withstand specified pressure conditions.<\/p>\n

              \n

              Running Overload Test<\/h1>\n

              The Running Overload Test evaluates compressor operation under specified overload conditions.<\/p>\n

              This helps assess the reliability of the compressor under demanding operating conditions.<\/p>\n

              \n

              Resistance to Rusting Test<\/h1>\n

              Applicable metallic components are evaluated for resistance to rusting according to the requirements of the standard.<\/p>\n

              \n

              Raw Material Requirements<\/h1>\n

              The BIS Product Manual for IS 10617:2018 indicates \u201cNil\u201d<\/strong> under the specific product raw-material requirement field.<\/p>\n

              However, manufacturers should still maintain proper control over materials used in the manufacture of compressors.<\/p>\n

              Important components may include:<\/p>\n
