Matters needing attention in selecting third-party testing institutions
1. Qualification and certification: select institutions with relevant qualifications and certification, such as CMA and CNAS, to ensure that the institutions have professional technical capabilities and service quality. Compare the names and measurement parameters of your own instruments and equipment with CNAS series of calibration suppliers. If the calibrated equipment is not within the scope of the calibration laboratory, it is usually measured according to the properties of the equipment.
2. Service quality and reputation: Choose institutions with good service quality and reputation, which can be evaluated by their historical records and customer evaluations.
3. Inspection scope and equipment: Select institutions with required inspection scope and equipment as required to ensure the accuracy and reliability of inspection results.
