Environmental stress screening is away of proving operational stability at extremes,such as desert conditions,hot manufacturing environments or very cold weather.Test types include highly accelerated lifetime testing(HALT)and highly accelerated stress screening(HASS)。
ESS is common for military products and components that often operate at extreme temperatures and for industrial products such as automotive components–both engine components and in-cabin assemblies.For military products,the testing temperature range is–55°C to+125°C。For industrial products,the common range is–40°C to+85°C。
