In order to further elaborate whether the high and low temperature test chambers meet the requirements set by the customer (or contract), the acceptance work has rules and regulations, and in the industry, there are also acceptance standards and third-party authority calibration (metering) specifications.
User acceptance method and acceptance criteria for high and low temperature test chambers: This standard is accepted in accordance with the “High and Low Temperature Test Chamber Technical Agreement†in the signing of equipment contracts between buyers and sellers. That is, the user and the high and low temperature test box manufacturers agreed on the temperature and humidity range, uniformity, fluctuation, temperature and humidity deviation, size, configuration and other indicators; to confirm whether the terms of the contract are met.
Invite third-party authorities to conduct calibration verification for high and low temperature test chambers: that is, if the customer requires third-party calibration verification, you can choose to measure at the factory or after the goods arrive at the customer, please check with the third party. The measurement is verified by the National Environmental Testing Equipment Quality Testing Center and has a calibration report (measurement certificate) with validity period. The calibration fee is negotiated before the two parties sign the contract. The measurement units include China Metrology Institute, Beijing Metrology Institute, Shanghai Metrology Institute, and Shenzhen Metrology Institute.
The acceptance of the high and low temperature test chambers is mainly based on the “high and low temperature test chamber technical agreement†in the equipment contract signed by the buyer and the seller. If third-party measurement is required, it should be explained in advance. It can be measured at the Beijing Yashilin factory, or a third-party measurement unit can be invited to the user unit for measurement.
