WARNING!!!
1. Strong magnets should Keep away from Ironware and some easily magnetized iron products, such as monitors, bank cards, computers, televisions, mobile phones and other
2. Magnets might affect water meter ,electric meter, gas meter and some metering equipment exist some inaccurate affect (Such as : if magnets placed near the meter, the meter will slow down)
3. These magnets are very powerful which should be handled with great care. Without parents supervised do not allow children to playing magnets as they could get injured. Especially pay attention to the small magnets , please place in somewhere children can't reach place.

Notice: The Seller will not be held liable for any damage or injury caused by these magnets.
Safety Warning about handling neodymium magnets  
1. Handling strong magnets in a proper manner is necessary to prevent personal injury and property damage, which include magnet damage.  
2. These magnets are not toys. Please do not give neodymium magnets to children under 3 years old. Small magnets pose a choking hazard, and can be lethal if swallowed. In addition, large magnets can easily pinch fingers. So always supervise children when playing with magnets and be sure they are aware of the dangers involved.  
3. Please keep magnets away from people who are wearing pacemakers or other medical devices. These magnets could also damage CRT monitors and TV's.  
 4. It is recommended to wear gloves when handling magnets.  
5. Always handle magnets individually. Do not handle multiple magnets at the same time unless they are widely separated or stacked together.  
 6. When placing magnets together, place a spacing material between them such as a piece of plastic, wood or cardboard so that they are easy to separate when needed.  
 7. Maintain a distance of at least 3 feet from other magnets or magnetically susceptible items when handling the magnets. Pay particular attention to scissors, knives, screw drivers or any other sharp metal objects.  
 8. To separate one magnet from the others, place them on a durable non-metal surface with the magnet-to-be-separated hanging off the edge of the table. Use one hand to firmly hold the other magnets on the table, especially those closest to the magnet being separated. Use the other hand to firmly hold the magnet you are separating. Push it down and away from the other magnets, until a magnetic attraction is no longer felt. Keep the separated magnets a safe distance from each other.

Yellowing Resistance Test Chamber

A yellowing resistance test chamber is a specialized piece of equipment used to evaluate the yellowing resistance of materials. It is commonly used in industries such as automotive, aerospace, and construction to assess the long-term color stability of materials exposed to various environmental conditions.

The test chamber simulates accelerated aging conditions by subjecting the material to controlled levels of heat, humidity, and UV radiation. These factors can cause materials to undergo yellowing or discoloration over time, which can negatively impact their aesthetic appeal and performance.

During the test, samples of the material are placed inside the chamber, and the temperature, humidity, and UV exposure levels are adjusted according to the desired testing parameters. The samples are typically monitored over a specified period, and any changes in color or yellowing are visually assessed.

The yellowing resistance test chamber helps manufacturers determine the durability and color stability of materials, allowing them to make informed decisions regarding product development and quality control. It can also be used to compare the yellowing resistance of different materials or evaluate the effectiveness of protective coatings or additives in preventing yellowing.

Overall, the yellowing resistance test chamber is an essential tool for industries that rely on materials with long-lasting color stability, ensuring that products maintain their desired appearance even after prolonged exposure to harsh environmental conditions.
