1, test equipment Salt spray test machine 2. Purpose of the test The salt spray tester tests the accelerated salt spray corrosion test on protective layers, parts, electronic components and industrial products of metal materials. 3. Reasons for possible equipment...
1, working principle The temperature regulation system in the climate box adopts the microcomputer PID automatic control mode; the humidity inside the box is controlled by the humidity generator, and the humidity in the humidity chamber is controlled to control the humidity of the air in the working chamber...
1. If such a thing occurs, check the equipment first, set the high temperature (40 degrees Celsius or 60 degrees Celsius), set the ambient humidity to 0, click on the operation, and see if the equipment will jump, or the heat pipe is shorted. The fault causes electric shock, and the constant temperature and humidity...
1, sampling Samples should be sampled at the manufacturer's finished product warehouse or sampled from the circulation area. 2, packaging and transportation The sample should be sealed and packaged, and the sample should be free from chemical contamination or any physical exposure, such as sun exposure...
Test conditions (1) Artificial xenon lamp aging conditions Light source: 6000 watt water-cooled xenon lamp. The cooling water is distilled water and ion-exchanged water, and the two are used in combination. Blackboard temperature: 63 soil 3 ° C Relative humidity: 65 5% Rainfall period: rainfall 18 minutes / light...
Formaldehyde emission chamber is mainly for the detection of formaldehyde emission in wood-based panels, interior wall coating materials, interior furniture and other products. The environmental instrument compartment of the ring meter distinguishes the old domestic test, which is more economical. The test results...
Preparation before the environmental test chamber test 1. Clean the environmental test chamber before the test, first use the cleaning agent (DH value ≥:.5 to clean the inner wall, then use the deionized small or distilled water to scrub the inner wall of the cabin, open the door, open the fan to the cabin...
1. Meet the standard: ANSI/AHAM AC-1-2006 portable household electric indoor air purifier performance test method 2. Manufacturer: Dongguan Huanyi Instrument Technology Co., Ltd. 3, cabin test room structure (allow the use of equivalent alternative materials and equipment) Test room size: internal...
1 Test Chamber: 1.1 The interior volume of the chamber shall be a minimum of 22 m3(800 ft3). The interior of the test chamber shall be free of refrigeration coils that condense water and items such as humidifiers with water reservoirs as condensate will have the potential of collecting...
1Significance and Use: 1.1 Limitations on formaldehyde concentrations in air have been established for some building products permanently installed in manufactured and conventional homes. This test method provides a standard means of testing typical product sizes, such as 1.2 by 2.4 m (4...
2.1 ASTM Standards: D 3195 Practice for Rotameter Calibration4 D 5014 Test Method for Measurement of Formaldehyde in Indoor Air (Passive Sampler Methodology)4 D 5116 Guide for Small-Scale Environmental Chamber Determinations of Organic Emissions from Indoor Materials/Products4 D 5197...
1.1 This test method measures the formaldehyde concentration in air and emission rate from wood products containing formaldehyde under conditions designed to simulate product use (see 11.5 and Note 7). The concentration in air and emission rate is determined in a large chamber under specific test conditions of...
