In the building industry, feuchtegefährdete Baustoffe (construction materials) include certain types of plaster, adhesives, insulation boards, paints and wall coverings that can swell, crack or lose adhesion once they absorb water. Builders mitigate the risk by incorporating moisture barriers, using low‑water‑absorbent finishes, and applying curing protocols that control humidity during installation. German technical standards—such as DIN 4108 for indoor climate and DIN 4109 for acoustics—specify moisture‑related performance tests, ensuring that feuchtegefährdete components meet minimum thresholds for water resistance (e.g., water absorption rates and differential pressure). Similarly, the European Union’s Construction Products Regulation incorporates requirements for tolerable water content and stability in the presence of humidity.
In textiles and fabrics, feuchtegefährdete fabrics are those that can retain moisture, which may foster microbial growth or cause color fading. Manufacturers often treat fibers with hydrophobic coatings or integrate breathable membranes to reduce moisture absorption. Textile care labeling uses water‑resistance indicators, and laundering guidelines warn against prolonged wet exposure for highly feuchtegefährdete goods.
Electronic devices with feuchtegefährdete circuitry—such as unsealed connectors or passive components—are vulnerable to corrosion, dielectric breakdown, or electrical shorting. Compliance with IEC 60745 or IP (Ingress Protection) ratings guarantees a specified level of moisture protection. In high‑humidity environments, designers might use conformal coatings or hermetically sealed housings to preserve reliability.
Understanding the classification of feuchtegefährdete items allows engineers, architects and consumers to implement appropriate design choices, maintenance schedules, and regulatory compliance measures. By controlling moisture ingress, the longevity, safety and functionality of sensitive products are protected, reducing repair costs and environmental impact.
