Key Differences
≠IS 3139 is a comprehensive specification covering design, performance, materials, testing, and safety in one document. The international approach is more modular, using separate standards for performance (ISO 5801), vibration (ISO 14694), sound (ISO 13347), and safety (IEC 60335 series).
≠IS 3139 specifies requirements based on Indian climatic conditions, such as higher ambient temperatures (e.g., 40°C for temperature rise tests), which may differ from the standard ambient conditions specified in some IEC/ISO standards (e.g., 25°C).
≠The Indian standard exclusively cites other Indian Standards (IS) for materials, motors (IS 1231), safety (IS 302), and testing. International standards reference a framework of ISO, IEC, and other globally recognized codes.
≠IS 3139 may prescribe a single default balance quality grade (e.g., G 6.3) for general-purpose fans, whereas ISO 14694 provides a more detailed application-based categorization (BV-1 to BV-5) requiring user/manufacturer agreement on the specific grade.
Key Similarities
≈Both IS 3139 and international standards like ISO 5801/AMCA 210 use the same fundamental principles and methodologies for aerodynamic performance testing, ensuring comparable results for airflow, pressure, and efficiency.
≈The principles of rotor balancing are harmonized. Both IS 3139 and ISO 14694 refer to IS/ISO 1940-1 for specifying balance quality requirements using the same 'G' grade system.
≈Core definitions and terminology for fan types (axial, centrifugal), components (impeller, casing), and performance parameters (static pressure, total efficiency) are consistent with international vocabulary standards like ISO 13349.
≈Electrical safety requirements in IS 3139 are aligned with international norms through the direct adoption of IEC 60335-2-80 as IS 302-2-80, covering aspects like protection against electric shock and guarding of moving parts.
