What to pay attention to when buying a furniture tester

What should pay attention to the purchase of furniture testing equipment? In the era of rapid development, manufacturers are more and more valued for the quality of the product, the same guarantee of product quality also requires testing equipment for evaluation, will inevitably allow more and more companies to pay attention to, as furniture Manufacturers, to buy furniture testing equipment to pay attention to what? Kunshan Haida equipment based on years of production experience for everyone to explain in detail.

First, the performance requirements of furniture testing equipment

1. Temperature set value: the desired temperature set by the control device;

2, the temperature gradient: the maximum value of the difference between the average temperature of any two points in the workspace;

3, temperature fluctuation: After the stability, as a point of space at any point of the difference between the highest and lowest temperatures;

4, the difference between the work chamber wall temperature and the working space temperature:

1) The high temperature level should not exceed 3% of the test chamber temperature

2) When the low temperature level is not higher than 8% of the temperature of the test chamber;

5, temperature deviation: ± 2;

6. Temperature change rate: The conversion rate between two given temperatures measured in the center of the workspace, in °C/min;

Second, furniture testing equipment structure requirements

1. The inner wall should be made of materials that are not resistant to oxidation and have a certain mechanical strength;

2. Insulation materials should be able to withstand high temperatures and have flame retardant properties. ;

3, heating and cooling device heat and cooling should not be directly radiated on the test sample;

4. The door should be sealed well, and the sealing condition has good anti-high-temperature aging and low-temperature hardening resistance;

5, the refrigeration system should not have leakage, leakage, oil leakage defects;

6. There should be sample holders for placing or hanging test specimens. The sample rack should have sufficient high temperature and low temperature performance.

7, there should be lead lead;

Third, furniture testing equipment safety and environmental requirements

1. The insulation resistance value should meet the following three requirements:

1) Cold 2MΩ or more

2) Withstand voltage test of 1MΩ or more in hot state and 50Hz AC voltage of 1500V and 5s of application pressure time;

2. The protective grounding terminal should be firmly connected with the equipment shell, in line with the provisions of 7.1.9 of GB/T 14048.1-2000;

3, with over-temperature, over-current, water and other protection and alarm devices;

4, the whole machine noise should not exceed 80dB (A).
