What does the vehicle PPH value mean?
2 Answers
Automobile PPH value refers to the number of faults per hundred vehicles, indicating the average number of problems occurring in every hundred new vehicles. A smaller value represents better quality. Here is a detailed introduction to the automobile PPH value: 1. Calculation method: PPH result = number of problems occurring in the evaluated vehicles ÷ number of evaluated vehicles × 100. 2. Usage tips: The smaller the value, the lower the vehicle's failure rate, and the better the vehicle's quality. 3. Importance: When purchasing a car, owners should pay special attention to the PPH value, which can effectively reduce the frequency of car failures and extend the vehicle's service life.
As a veteran in the automotive industry, PPH actually stands for Paint Protection Hardness, which is the abbreviation of Paint Protection Hardness. We measure it using the pencil hardness test method, where a higher value indicates harder paint that is more resistant to daily scratches. For example, in automobile manufacturing, if the original factory paint has a high PPH, new cars are less prone to scratches; while in aftermarket coating products, such as 9H ceramic coatings, they can increase the PPH value, making the car more durable. Environmental factors have a significant impact, as strong sunlight can reduce PPH and accelerate paint aging. Regular maintenance like car washing and waxing can maintain high PPH levels, reducing repair costs. From my experience, high PPH paint not only extends the lifespan but also preserves the vehicle's value, making it worth the attention of car owners.
