Strengthen product waterproofness: analysis of professional testing methods and steps

Every time we pick up a new phone or put on a coat, we hope it will remain perfect even on rainy days.After all, who doesn’t want to stay dry in a heavy rainstorm, right?But in fact, waterproof performance is a major challenge in product design, especially for electronic products. Waterproofness is not only related to the user experience, but also directly related to the life and reputation of the product.So, how do you evaluate a product’s water resistance?Professional waterproof testing is key!Today, let’s talk about the professional testing methods and steps that need to be followed when enhancing the waterproofness of products.

1. The importance of waterproofing: why waterproofing cannot be ignored

We have all had the experience of buying an expensive smart watch and excitedly wearing it for swimming, only to have the watch damaged by water penetration, which has become a heart-wrenching memory.The occurrence of this situation is not accidental. It is often related to insufficient waterproof testing or misunderstanding of waterproof standards.Waterproofness not only means "being able to withstand the invasion of water", it also includes how to judge how much water pressure a product can withstand in different environments, how long it can be exposed for a long time without being damaged, etc.

For example, a mobile phone with a waterproof rating of IP68 can be immersed in a water depth of 1.5 meters for 30 minutes without being damaged, which is an extra guarantee for users.But how was this standard established?There are strict testing steps and specifications behind it, let's take a look.

2. Core standard for waterproof testing: IP level

The IP (Ingress Protection) rating is an important criterion for evaluating the waterproof and dustproof capabilities of a product. It is usually expressed with two digits.The first number represents dust resistance, and the second number represents water resistance.After understanding this standard, you will find that the waterproof capabilities of many daily products have clear boundaries as early as the design.

For example, a product rated IP67 means it can withstand short-term water immersion (such as within 30 minutes), while IP68 means a higher waterproof level and can handle deeper and longer immersion.Have you ever had questions about waterproofing standards due to improper purchases?In fact, as long as you understand this standard, it will be easier for you to choose the right waterproof product.

3. Professional waterproof testing methods: make your products “watertight”

To ensure that a product is waterproof, it needs to go through a series of professional tests.The steps for these tests are rigorous. Here are some common waterproof testing methods:

• Water immersion test:This is a testing method that simulates a product being immersed in water for a long time.Usually, the product is placed in a water tank to simulate a water immersion state of a certain depth and time to check whether it will seep water.
• Water spray test:For some products that do not need to be soaked for a long time but need to withstand rain damage, water spray testing is a common choice.Use a high-pressure water gun to spray water at a certain angle to simulate the performance of the product in heavy rain.
• Pressure water test:Pressure water testing is used to simulate the pressure of products in a deep water environment.This type of testing is commonly used in electronics and outdoor gear.

For example, a mobile phone from a well-known brand successfully passed the IP68 standard after a water spray test. It can be immersed in water at a depth of 1.5 meters for 30 minutes without any water penetration.The science and rigor behind this kind of testing are beyond our daily imagination.

4. How to choose suitable waterproof products: from the user’s perspective

For most consumers, water resistance is an important but often overlooked purchasing criterion.So, how to choose a truly suitable waterproof product among the dazzling array of products?

Be clear about your needs.If you are someone who likes to do outdoor sports, electronic products with IP67 or higher waterproof rating would be a good choice.For everyday items that only require light protection from water, IP54 or IP55 standards are sufficient.When choosing a product, you can consider the following:

• use:Are you regularly exposed to water?Is it swimming, surfing, or the occasional rain?Different usage scenarios have different requirements for waterproofness.



• Waterproof level:Understand the waterproof rating of the product to ensure it meets your actual needs.
• Test record:Choose a brand that has undergone strict waterproof testing. For example, Hirays provides comprehensive waterproof testing services to ensure that each product can work perfectly in a variety of environments.

For example, an outdoor headset from Hai Ruisi has passed the IPX7 level waterproof test and can be immersed in 3 meters of water for 30 minutes without damage.This is undoubtedly a huge convenience for users who like to listen to music while swimming.

5. Product optimization after waterproofing test: How to make products more “water-resistant”

Waterproof testing is a part of product production, but how to further optimize the waterproofness of the product after testing is also an important task for the R&D team.Typically, optimization measures include enhanced sealing design, use of waterproof materials, improved joint treatment, etc.

For example, after many waterproof tests, some smartphone brands will redesign the waterproof interface and adopt a more sealed structure and more durable waterproof rubber ring to enhance the water resistance of the mobile phone in harsh environments.

Goal: Steps You Can Do to Optimize Waterproofing

1. Ensure the sealing of the shell: Use high-quality waterproof rubber rings to ensure that all interfaces and buttons can resist moisture penetration.
2. Choose waterproof materials: Use nano-coating or special waterproof materials to increase the waterproofness of the product.
3. Conduct multiple rounds of testing: Not only testing in the lab, but also simulating different conditions in the real environment to ensure that the product performs well in a variety of environments.
4. Provide user guidance: clearly indicate the waterproof level and applicable scenarios on the product packaging or instructions to help users use it correctly.

Conclusion: Water resistance is the "lifeline" of brand quality

With the continuous advancement of technology and increasing consumer demands, waterproofing has become an integral part of many products.Through scientific waterproof testing and continuous optimization, brands can not only improve product quality, but also provide users with a better experience.

Imagine that future products will no longer be "afraid of water" and can even provide more functions underwater.This is an exciting future and a source of motivation for the brand to continuously pursue excellence.
