Have you ever wondered what a light bulb lab is? Or have you ever had a complaint from your customer that your product did not work in a timely manner nor had a short life? How to say, such a thing does not mean that your company machine is low in quality and standard.
This is because all products must have the negative effects of the environment in which they are placed. For example, when a lithium-ion battery is placed in extremely cold conditions, it will deteriorate in terms of life and storage capacity.
Therefore, before you put your product on the market, you must make sure that the parts of your product are strong and durable to withstand the bad things. In such a situation, there is no doubt that the thermal laboratory will help a lot.
So, today’s guide will walk you through the important parts before you decide whether or not to buy a fire shock test room. This guide includes many sections ranging from specifications, applications, specifications, work standards and other important information about the fire laboratory.
Now, let’s dive into today’s topic.
Definition of thermal shock.
Being a rapid changer of hot and cold, the internal part of the tested sample, such as metal, will have a large temperature difference in a short time, thus high temperature stress is induced. This event is called a warm-up.
For example, during a fire in the house, the fire is heated quickly. The resulting temperature differences cause different parts of the glass to expand in different ways, which can lead to thermal shock. Being under too much pressure, glass can lose its integrity and eventually crack.
What is Thermal Shock Resistance?
By definition, it refers to the ability of the tested product to withstand temperature changes, whether during heating or cooling. For example, silicon nitride, the most heat-resistant material, exhibits high resistance to thermal shock, tested by heating it to 550 ℃ (1022 ℉) and quickly cooling it by dropping it in water.
Definition of thermal shock properties.
Thermal shock test chamber, also known as thermal shock chamber, shock equipment or ambient screen test). In general, thermal testing equipment shows the effect of rapid changes between hot and cold zones to determine the shock resistance of your tested product.
More specifically, the thermal chamber uses a cold storage system and another heat-sensing system to test product performance and parameters after sudden temperature changes. In other words, a hot chamber is used to test the ability of a structure or composition to withstand long periods of continuous exposure to extremely high temperatures and extreme temperatures.
The thermal laboratory consists of a table area that carries the product under test and automatically transports the product under test between two separately controlled hot and cold areas. Besides, it is good for you to see the product during the change process in the visible window installed in the lighting laboratory.
All of these useful tools help in achieving quick temperature changes for heat shock. Therefore, the greenhouse can experience chemical changes or physical damage caused by thermal expansion and contraction in a short period of time.
Purpose of using a fire shock test chamber.
When you want to buy a product correctly, you must have a complete understanding of the product’s application. To begin with, the laboratory is designed to detect defects in electrical assemblies, glass, rubber, plastic, metal, ceramics and other materials.
Purpose of application at different stages of product development:
R& D (research and development) engineering process: you can find out the defects of the product’s components and the lighting test room.
Level of improvement: When you find the weakness of your product, you can make changes accordingly.
Simulated Test Evaluation: A real heat shock chamber is the key to measuring the success or failure of your product in the real world. Because things outside are complex and different. It is possible that your product will be exposed to extreme cold and hot conditions at the same time. In order to prevent such situations from happening, the need for a thermal laboratory is clear.
Go-to-market: You can add valuable experience data to your product description.
Two types of fire labs
The thermal shock test room can be divided into zone 2 and zone 3. The difference between Zone 2 and Zone 3 is the room and the test system. The 3 zones include the hot zone, the cold zone and the test zone. The tested sample is placed in the test area. Zone 2 includes the hot zone and the cold zone. The tested sample is placed in a basket.
Four reasons to use a fire lab.
A very competitive market:
With the rapid development of the national economy, various companies in China are running to gain opportunities to hold a place in the market, namely plastic, metal and plastic industry.
Advanced customer requirements:
The more competitive the market, the faster the product replenishment.
Therefore, there are many other options for customers. To stand out from your competitors, you must do your best to improve the quality of your products.
Responsible for Product Safety:
Before putting a product on the market, you need to achieve product safety as much as possible. High security makes a good product and a high end product brings a steady flow of passengers!
Profitable performance:
With high performance, our thermal shock test chamber is for sale at factory price. Therefore, it is the first choice for you among other similar products.
The virtues of a thermal shock test chamber?
Air and air shock testing.
Refrigeration system (2 units of compressor).
Insulation (polyurethane foam).
Temperature adjustment and recovery time can be controlled within 5 seconds.
Low temperature of -70 ℃ to high temperature of 200 ℃.
Transfer directly between hot and cold zones vertically in the stainless steel travel basket.
Energy saving design with Japanese or German technology, reducing electricity consumption by 20%.
Compact design, saving space.
Shelves or racks designed to put different products. Standard window designed to allow product viewing.
What is the Thermal Shock Test Standard?
IEC68-2-1 Environmental testing – Part 2: Test methods – Test A: Cold.
IEC 68-2-2 Environmental testing for electrical and electronic products Test methods – Test B: Dry heat.
MIL-STD-810D Environmental Test Methods and Engineering Guidelines.
How to choose a fire house?
At the time of purchase, they have what they want.
There are five areas to consider when purchasing a heated lab:
Heat sensitivity
Effect temperature refers to the maximum temperature that can be reached in the test area. Note that this is not the maximum temperature of the preheating and precooling rooms;
Test weight
Test load affects the number of samples that can be applied. Generally speaking, the bigger the load, the better;
Reset the time
Transition time is the time it takes for a test object to move from one temperature to another. All our specifications are ≤5min. The less time, the better;
Defrost time
The longer the winter break, the better. It is desirable to have a manufacturer that can do 1000 defrost cycles once. The shorter the cooling time, the worse the ventilation of the device;
Location of sensors
Sensors must be placed in the test area. Some manufacturers put sensors in the air ducts. Although it is only 10 cm from the test area, this difference in strength is very important. It does not accurately reflect temperature changes on the surface of the probe.
