From the design requirements, it is fine to use the wipers for 4-5 years, but in actual use, many car owners have to replace them every 1-2 years. This is mainly because in daily use, many situations will shorten the life of the wipers.
For example, hot weather and extremely cold weather have a greater impact on the working conditions of the wipers. You can replace the wipers in advance, or prepare one or two pairs in advance.
Wiper life specified in the standard
When manufacturers produce wipers, they have a durability requirement.
According to the standard, the service life of a pair of wipers is about 5 years, and the service life of wiper rubber strips should be more than 1.5 years.
How long is the replacement cycle of wipers?
1. Actual replacement cycle
Generally speaking, the replacement cycle of wipers is about 1-2 years. If you only replace the wiper rubber strips, you may have to replace them every six months to one year.
In addition, many car maintenance manuals also require regular inspection of wiper blades.
2. Why is the life span not as long as expected?
The first is dry scraping, which causes greater wear and tear on the wiper rubber strips.
Under dry conditions, the maximum friction force of the wipers is close to 20N, while under rainy conditions, the maximum friction force of the wipers is less than 14N.
The second is exposure to the sun, which will cause the wiper rubber strips to age and harden, and its performance will decrease.
Sunlight has a great impact on the aging of wiper blades. High temperature will damage the rubber material of the wiper blades. In the long run, it will cause great damage to the material, causing deformation or loss of elasticity.
In addition, some improper operations may damage the wiper arms and wiper motors, which should also be noted.
For example, forcibly bending the wiper arms when washing the car, or forcing the wipers to start without thawing in winter when the wipers are frozen to the windshield, will cause damage to the entire wiper system.
Conclusion
In short, the actual service life of wipers is not as long as expected, which is related to the local climate, actual usage, etc. Car owners, please remember to check the condition of your wipers regularly and replace them in time to avoid affecting your driving conditions.
