Salt Spray Test Chamber | Significance to Get a Valid CE Certification

The salt spray test chamber without a CE Certification, It’s quite difficult to win an salt fog test chamber order from the European customers. Most European customers (and unfortunately also many of their Asian suppliers) don’t have a clue about CE, and they just accept any CE certificate without even checking if it is compliant with NANDO.
 
Unfortunately, but that’s what is currently happening with China salt spray test chamber manufacturers, but Wewon Environmental Chambers Co., Ltd. want to act as a responsible company. They don’t care what others may think or say, because this matter could ruin their reputation.
 
Many Chinese companies like Certitec and Shenzhen CCT have issued fake CE certificates. I mean fake, simply because these companies are not so-called notified bodies. These companies should be forbidden to issue such documents. Even more important: A CE certificate conform to NANDO should not be a custom
document as you say, but it should be a standard document for products exported to Europe. It is not voluntary but compulsory !

The above photo mentioned is our latest design for our salt spray test chamber. We have updated our design and the body structure with a higher operate control panel for operator during testing work. It is the somatological design, The testing engineer will no bend down their body when they are doing a program setting work.
 
When we visited our local clients and talked with them, The engineer request this design, The new potential client may more pleasure to use this somatological design salt spray chamber. This somatological design makes the engineer will feel more comfortable when they are doing the program setting work standing there.

Any distributor who is importing the salt spray test machine into the EU is liable if the CE certificate is not valid, not the Chinese manufacturer. The CE certificate should be prove for European authorities, our safety advisor, and our prospects that a machine is fully compliant with EU standards. Wewon Environmental Chambers Co., Ltd. can handle the certification if you work with a company who can act on behalf of the notified body.
 
Sorry for being so strict about the CE but there are serious penalties in Europe if they don’t follow with the rules … The European client probably ask their other salt spray chamber supplier for salt spray test chamber price because they have to show the CE certificate before they sell the machine. And also hand-over the complete electrical drawings and installation instructions before they ask for the order.

 
And they have to translate the Word documents in Dutch or any local language. There too many salt spray chambers specification grammar mistakes from Chinese suppliers, because they don’t understand the European legislation (like no experience with NANDO). It is just too much money to take any risks.

The European distributors and resellers will have to stick to the law if they are selling the salt spray test chamber in their local market. Customs can even block imported salt spray test chamber when the reseller cannot prove that documents are complete and valid. And the European distributor as importer are responsible and liable for product safety when it enters the EU.
 
The European distributors and resellers cannot import machines without CE certificate otherwise they would break the law and Dutch customs may hold the shipment if they could not show a valid certificate. This is mostly worry and mentioned from the European customer when they bought an environmental chamber
from Asian countries.
 
Do you have a spare parts list for the European distributors and resellers ? For example, Temperature humidity balls, LED light , does the cooling require any replacement of cooling fluid. Do you have guidelines to replace parts of the machine ? European distributor would like to have some critical spare parts on stock for their salt spray test machine to ensure that they can send it to the customer with one working day.

The salt spray test is mainly divided into four types: Neutral salt spray test (NSS); Acetate spray test (AASS); Copper accelerated acetate spray test (CASS); Alternating salt spray test. Comparison of four salt spray test methods in GB/T 10125 as below Excel form mentioned:

Meanwhile, According to the salt spray test procedure, The plug for salt spray testing equipment should be of Type E & F hybrid CEE 7/7 because that’s the most standard and compatible plug across Europe. See below the socket outlet which is used in some European countries, such as France, Belgium and Luxembourg.
 

This is why plug should have an so-called “female contact” opening to ensure that the earthing pin in the socket will be compatible with the CEE plug. This is really important for the European clients because they have to comply with the safety rules in their local place. Furthermore, Here are some international testing standards for salt spray testing chamber:
