Most polymer materials corrode more outdoors due to humidity (especially condensation) than other factors, so the moisture resistance test of coatings is also an important method for evaluating their corrosion resistance. This method can be used as an important evaluation tool to examine the corrosion resistance performance of coatings.

The ISO 6270:2017 series of standards is a test method standard for evaluating the moisture resistance of coatings, consisting of three parts:

Part 1: Determination of moisture resistance of paints and varnishes Part 1: Condensation (single-sided exposure)

Part 2: Determination of moisture resistance of paints and varnishes Part 2: Condensation (exposed in a test chamber with a heated water tank)

Part 3: Determination of moisture resistance of paints and varnishes Part 3: Condensation (exposure in a test chamber with heated and bubbling water tank)

Austens produces different models of condensation test chambers based on the above standards to meet the testing needs of different products!

The AOTSI-6270-1 continuous condensation water test chamber is designed in accordance with GB/T 13893-2008 "Determination of Moisture Resistance of Paints and Varnishes - Continuous Condensation Method" (equivalent to ISO 6270 Part 1) and ASTM D 4585 requirements, to evaluate the moisture resistance of coatings, coating systems, and similar products in high humidity environments with continuous condensation. This testing method specifies a continuous condensation performance test that may occur on the surface of coatings under harsh exposure conditions. It is suitable for coating systems including porous substrates (such as wood, gypsum, and paper faced gypsum board) and non porous substrates (such as metal), and can reveal coating failure (including bubbles, stains, softening, wrinkling, and embrittlement) as well as substrate failure phenomena.

This instrument uses 100% condensing humidity to simulate and accelerate damage to metals, coatings, and organic materials caused by dew. Increasing the temperature of condensed water will cause damage to the dew more quickly than natural exposure. It has the characteristics of simple structure, easy operation, and high reproducibility of experimental results.

In the AOTSI-6270-1 continuous condensation water test chamber, temperature and humidity can be invisible dewdrops or continuously flowing hot condensation water. The AOTSI-6270-1 continuous condensate test chamber can be set with a drying cycle to remove osmotic pressure, or it can accelerate moisture erosion by increasing the condensation temperature.

The purchase and operation costs of the AOTSI-6270-1 continuous condensate water test chamber are quite low. It does not require special installation conditions and can be used normally by simply connecting to a regular power source and tap water. Its functional diversity, speed, and low operating cost make the AOTSI-6270-1 continuous condensate testing chamber a highly cost-effective condensation testing machine on the market.

The three operating conditions of the test chamber can be controlled through programming: humidification, natural cooling, drying, and the corresponding temperature and operating time for each condition, and the total time and number of cycles for program operation can be set.
