ASTM D4585 test as part of its polymer testing service services Essence The standard describes an accelerated aging test that allows the water resistance of the coating by using controlling condensation. More specifically, this approach illustrates the principles and operating conditions required from the laboratory to the laboratory. In addition, ASTM D4585 did not provide any instructions for sample preparation, specific test conditions, and no guidance or requirements for evaluation results. Finally, the ASTM D1735 and ASTM D2247 standards are the alternatives of this approach.
Continuous condensation test box Use the controlled condensation to test the water resistance and factors to be considered:
The purpose of ASTM D4585 is to evaluate the ability of the coating through condensation test to resist the deterioration caused by water. In fact, the latter includes the exposure of the sample to the controlled temperature environment with saturated steam, and the test results of these types are passed or unable to be determined. In addition, the test can evaluate the coating or complete coating system because the damage observed in this test may be caused by various factors. For example, it may be caused by the following reasons: substrate pollution, insufficient surface preparation or coating itself. In order to measure the water resistance of the sample, the test depends on the assessment of aesthetic characteristics, such as: color changes, foaming, bonding and softening losses, which have been described in detail in other standards.
AOTSI-6270-1
Continuous condensed water test box According to IOS 13893-2008 Measurement of the Demolstation of Color and Paint-Resistance Continuous Concretion Method (equivalent to the ISO 6270 standard part 1) and ASTM D 4585 Requirements Design Design It is used to evaluate the humidity resistance of coating, coating system and its similar products in the high humidity environment of continuous condensation. This test method specifies a continuous condensation performance test that may occur under the coating surface under severe exposure conditions. It adapts to the coating system includes porous substrates (such as wood, gypsum, and paper plaster plates) Materials (such as metal), etc., can reveal the phenomenon of coating destruction (including air bubbles, staining, softening, wrinkles and brittleness) and the destruction of the substrate. The instrument uses 100%condensate humidity to simulate and accelerate the damage of metal, coating and organic materials caused by dew. Increasing the temperature of condensation water will be more damaged than the damage of natureSpeed up.It has the characteristics of simple structural, convenient operation, and high test results.
Temperature and humidity In AOTSI-6270-1
Continuous condensate test In the test box , humidity can be seenDon’t see the hot and cold water that continues to flow continuously.The AOTSI-6270-1 continuous condensate test box can set a dry circulation to remove the penetration pressure, and it can also accelerate the humid erosion by increasing the condensation temperature.
AOTSI-6270-1 The purchase and operation cost of continuous condensed water test boxes are quite low. It does not require special installation conditions. It only needs to connect to ordinary power and tap water.Normal use.Its functional diversity, fast, and low operation costs make the AOTSI-6270-1 continuous condensate test box a very cost-effective gel test machine on the market.
