introduction
Reliability is an important indicator for evaluating household appliances. In order to provide a scientific and consistent household appliance reliability test method and standardize household appliances
Reliability evaluation index, GB/T 24986 "Reliability test and evaluation of household and similar electrical appliances" was formulated. In order to avoid lengthy standards,
GB/T 24986, which describes the product characteristics of different types of household appliances, is composed of the following parts in accordance with the principles of universality and particularity.
--- Part 1.General requirements.
--- Part 2.Particular requirements for refrigerating appliances.
--- Part 3.Particular requirements for washing machines.
--- Part 4.Particular requirements for room air conditioners.
--- Part 5.Particular requirements for room heaters.
--- Part 6.Particular requirements for air purifiers.
Part 1 provides the index selection principles and general requirements for reliability testing and evaluation methods for household and similar electrical appliances.
Part 2 to Part 6 give the specific requirements for reliability testing and evaluation of various household products.
They can be used together to form a complete household appliance reliability test and evaluation system.
