Enterprises will have a variety of equipment, and the equipment itself needs to be calibrated to ensure the eligibility of use, so that the production capacity of the products produced can meet the requirements. As a testing instrument, the rain test box needs to be regularly maintained, maintained, and calibrated, and a measurement certificate issued by a third-party measurement certification agency is required.
The measurement certificate is equivalent to the "identity certificate" of the rain test box. It is verified and calibrated by a third-party measurement agency with certification qualifications before it can be stamped and effective. The rain test box must undergo a strict on-site measurement before leaving the factory, and the corresponding measurement certificate will be issued, and then a regular re-inspection will be carried out every year.
The relevant contents of the rain test box measurement can be divided into:
1. Appearance requirements: no damage, no bumps, no deformation.
2. Nameplate identification: product name, model, factory date, address, telephone number.
3. Size standards: swing pipe inner diameter, water spray hole diameter, swing pipe radius, outer box size, inner box size.
4. Angle calibration: Swinging angle of the swing pipe (120°)
5. Swinging pipe swing cycle: 120° swing pipe swing cycle, 350° swing pipe swing cycle
6. Water flow: 0.07L/min water flow per hole
7. Rotating table: 600mm diameter, 1r/min speed
The rain test chamber is inspected on site by a dedicated third-party metrological inspector and recalibrated once a year. Therefore, when choosing a waterproof test device, companies should pay attention to whether the rain test chamber can provide the corresponding metrological certificate.
Yuexin-focuses on the research and development and production of rain test chambers, and looks forward to every communication with you.
