Single-Sided Exposure Condensation Chamber

Single-Sided Exposure Condensation Chamber, For many polymer materials used outdoors, experience shows that moisture—especially condensation—causes more serious corrosion than any other factor. Therefore, testing the resistance of coating films to humidity is a key method for evaluating their corrosion resistance.

ISO 6270:2007 Standard Overview

The ISO 6270:2007 series defines test methods for evaluating the humidity resistance of coating films. It consists of three parts:

• Part 1: Condensation (single-sided exposure)
• Part 2: Condensation (in-cabinet exposure with heated water reservoir)
• Part 3: Condensation (in-cabinet exposure with heated and bubbling water reservoir)

BIUGED Condensation-Water Climatic Chambers

To meet the needs of different industries and customers, BIUGED INSTRUMENTS designs and manufactures a variety of condensation-water climatic chambers in compliance with these standards.

Single-Sided Exposure Condensation Chamber

This chamber provides controlled test conditions for determining the resistance of paint films, paint systems, and related products to condensation. It is suitable for coatings applied to both porous substrates (such as wood, plaster, and plasterboard) and non-porous substrates (such as metals).

By exposing test panels to continuous condensation, the chamber helps predict performance under severe environmental conditions. Failures such as blistering, staining, softening, wrinkling, embrittlement, and substrate deterioration can be detected quickly.

Advantages of the Tester

The chamber is fast, user-friendly, and cost-effective. It uses 100% condensing humidity to simulate and accelerate moisture damage caused by dew and rain. Unlike water immersion or non-condensing humidity tests, this method increases the moisture temperature to shorten the testing cycle and deliver faster results.
