Standards and regulations relating to air conditioners in each country have increasingly become more diversified each year with a wider scope of targeted products and stricter requirements. Regulations are classified as voluntary (recommended) and mandatory. In case of mandatory regulations, manufacturers must comply with regulations by changing product specifications or withdraw from the market since the import, production, and sale of noncompliant products are prohibited. Compliance with regulations often varies. Depending on the circumstances, manufacturers must either submit a self-certification of conformity or have their products tested by a third-party inspection body authorized by regulatory authorities.
Most of the countries across the globe require certification of product safety based on International Electro-technical Commission (IEC) standards and a performance inspection. Recently, more countries are implementing regulations relating to the issue of the global environment. Environmental regulations tend to start with energy-saving regulations then progress to refrigerant regulations, hazardous substances regulations, and recycling regulations.
