Shenzhen United Testing Technology Co., Ltd

Suitable for external lighting, signal devices and automotive lamp shell protection, can provide realistic analog electronic products and their components during the transportation and use of the spray test may be subjected to water and other environment, to detect the waterproof performance of various products. Common operation mode 1.Preparation: First, select a test device that can simulate the real rainfall conditions. A spraying system or spray device can be used to ensure a uniform and continuous flow of rainwater. 2.Sample preparation: Cut the material to be tested into the appropriate size, usually square or rectangular. Ensure that the edges of the sample are flat, with no obvious defects. 3.Install the samples: attach the sample to the device to ensure full level and withstand rain. 4.Adjust test parameters: adjust the operating parameters of the shower, such as flow and spray Angle. 5. Experimental: turn on the shower and start the experiment. Usually the experiment lasts fo...

The vibration test methods can be divided into sinusoidal vibration and random vibration: Sinusoidal vibration is often used in the laboratory test method, to simulate rotation, pulsation, shock (in ships, aircraft, vehicle, space aircraft) on the vibration and the resonance frequency analysis of product structure and little note to pick up card is given priority to, it is divided into two kinds of sweep vibration and fixed frequency vibration, the harsh degree depends on the frequency range, loss amplitude, test duration. Random vibration is assessed as the seismic resistance strength of the overall structure of the fire module product and the delivery environment in the packaging state, and its severity depends on the frequency range, GRMS, test duration and axial direction.

The specific items of the food contact material testing of the juicer are as follows: 1. Stainless steel knife head test items: Total chromium 2. PP material test items: Specific gravity Melting point (only for PP) n-hexane extractives Xylene extractives

A lso known as "oven", adopts electric heating method for blast cycle drying test, which is divided into two kinds: blast drying and vacuum drying. Air drying is to blow the hot air through the circulation fan to ensure the temperature balance in the box; vacuum drying is to use vacuum pump to pump the air in the box, the atmospheric pressure is below the atmospheric pressure, so that the product in a very clean state. I t i s a commonly used instrument and equipment, mainly used to dry the sample, and can also provide the temperature environment required for the experiment. Dry box is used in chemical industry, medicine, casting, automobile, food, machinery and other industries. Generally divided into galvanized steel plate and stainless steel liner, pointer and digital display, natural convection and blast cycle, conventional oven and vacuum type.
