In our daily lives, our electronics are often challenged by water and dust. Whether we're relaxing by the pool or exploring the great outdoors, we want our smartphones and professional sports gear to be safe and secure. This brings us to the concept of water and dust resistance.
Today, we'll take an in-depth look at two common standards for water and dust resistance: ATM and IPXX, and how to use an airtightness tester to test your product's waterproof rating.
1. Definition and Classification of ATM Water Resistance Classes
The ATM Water Resistance Rating originally originated in watch manufacturing to evaluate the water resistance of a watch underwater.1ATM is actually a unit of standard atmospheric pressure, equivalent to water pressure at a depth of 10 m. ATM waterproofness ratings are categorized according to pressure values ranging from 1ATM to 100ATM, with higher values indicating greater waterproofness.
- 1 ATM：相当于 10 米水深的压力。通常认为这是最基本的防水等级，可以抵抗轻微的雨滴和洗手时的溅水。
- 2 ATM：大约相当于 20 米水深的压力。适合日常生活中的防泼水，如雨水和洗手。
- 3 ATM:大约相当于 30 米水深的压力。适合游泳和短时间的浅水活动。
- 5 ATM:大约相当于 50 米水深的压力。适合更频繁的水上活动，如浮潜。
- 7 ATM：大约相当于 70 米水深的压力。适合一些水下运动，但不适合潜水。
- 10 ATM:大约相当于 100 米水深的压力。适合大多数水上运动，包括一些潜水活动。
- 15 ATM：大约相当于 150 米水深的压力。适合更深入的潜水活动。
- 20 ATM：大约相当于 200 米水深的压力。适合专业的潜水和水上运动。
- 30 ATM：大约相当于 300 米水深的压力。适合专业的潜水员和极限水上运动。
- 50 ATM：大约相当于 500 米水深的压力。适合专业潜水和其他极限水下活动。
- 100 ATM：大约相当于 1000 米水深的压力。适合深海潜水和其他专业水下作业。
要测试产品的 ATM 防水等级，可使用 JCGK Airtightness TesterThePrecision Engineering's instruments can simulate the pressure of different water depths and determine the waterproof ability of the product under test by monitoring the pressure changes inside the product. The test procedure is simple and efficient, just connect the tested parts, set the pressure parameters, the tester will automatically complete the test and output the result report.
2. Connotation of IPXX protection class
Unlike the ATM standard, which evaluates water resistance alone, IPXX is a combined protection rating that specifies the requirements for protection of electronic products against solid particles (dust) and liquids (water).IP is an acronym for IngressProtection. The standard consists of two digits, the first indicating the dustproof rating (0-6) and the second the waterproof rating (0-9), with the higher the number, the greater the protection.
以 IP68 这一常见等级为例，6 代表最高的无尘防护能力，可以防止任何尘粒进入；而 8 则表示较高的防水等级，能够长时间浸入水中而不会渗漏。获得 IP68 认证就意味着产品具备卓越的无尘无渍性能。
It should be noted that the testing requirements for IP68 rating are extremely strict. In addition to the water immersion test, it also includes vibration, temperature difference cycle and other multiple complex assessment links, which puts forward high requirements for the overall sealing performance of the product.
3. Application of airtightness testers in IPXX testing
作为国内领先的Air tightness testing equipment制造商，JCGK 精诚工科的检测仪产品已广泛应用于 IPXX 防尘防水测试领域。JCGK 的仪器不仅拥有压力检测精度高、温度补偿自动化等先进技术，而且数据传输便捷、操作简单，可以轻松完成复杂的模拟环境测试。
Automotive parts air tightness testing process
使用 JCGK Airtightness Tester进行 IPXX 等级测试时，首先需要将被测产品通过特制密封夹具与检测仪连接，然后根据相应防护等级设置好测试压力、检测时间、泄漏数值等参数，即可开始自动检测。During the whole process, the tester will monitor the change of inflation pressure in real time, and quantitatively evaluate the sealing performance of the product through the rate and degree of pressure drop. The final result will be presented visually with precise data, which is easy for technicians to analyze and interpret.
4. Differences between ATM and IPXX
While both ATM and IPXX are standards for measuring water resistance, they have different emphases; ATM focuses more on the ability to withstand underwater pressure, while IPXX provides a more comprehensive assessment of dust and water resistance. Which standard you choose depends on your specific needs and environment.
5. Practical application case studies
ATM 和 IPXX 的防护等级标准在不同行业的应用中各有特色。以 JCGK Airtightness Tester为例，它们已在防水手表、智能手机、运动设备等多个消费电子领域发挥了重要作用。
Smartwatch sealing test case
The watch industry has always been a major application of the ATM standard. Precision Technology once tested the 5ATM waterproof capability for a famous watch brand, and found that there were defects in the design of the pressure seal through the tester, so the customer improved the structure in time to ensure the waterproof safety of the product.
Bicycle code meter air tightness test case
Outdoor sports equipment also requires excellent waterproof and dustproof performance. A cycling equipment brand has used the Precision Engineering tester to test its bicycle code meter according to the IP67 standard, simulating the harsh environment of outdoor rain, and finally ensuring that the product is waterproof and durable.
Summarize
防水防尘标准的选择并不复杂，了解 ATM 防水等级和 IPXX 防护等级的区别，根据实际需求选择合适的测试方法，我们就能确保自己生产的产品在面对水和尘的挑战时，表现出最佳性能。尽管二者有所差异，但本质上都是为了帮助消费者选择出符合需求的优质产品。测试标准的选择需因产品而异，更重要的是要使用专业可靠的检测设备，比如 JCGK Airtightness TesterTheOnly through rigorous testing and continuous optimization can manufacturers truly improve the quality of their products and win the trust of consumers.
