Introduction

At present, the reliability of the technology has been widely applied to the automotive, medical, military and aerospace and other fields. Reliability Technology has become a measure of product quality An important means of volume, long-term practice proves the reliability of technology for improving the quality of products is significant. China's home appliance industry is a mature industry, China has become the world's household electrical appliances production, consumption and export powerhouse. At present, many domestic air-conditioner manufacturers are conducting research conditioner reliability, the reliability of test methods for air conditioners in particular be Research. In view of this situation, it is necessary to develop "household and similar use room air conditioner reliability test methods" national standards, thereby Reliability test method for the air conditioner to regulate the industry and guidance. Household and similar room air conditioner Reliability Test Methods

1 Scope
