TS 12558

TS 12558 is a service standard that addresses the general rules for authorized maintenance and repair services for wood, metal and/or PVC door and window systems. Its subject is not the products alone, but the service framework used by authorized providers who maintain, adjust and repair these systems. In practical terms, it helps define a common structure for service work in a field where correct operation and ongoing upkeep are important throughout the product life cycle.

What an authorized service model means

In door and window systems, an authorized service is generally understood as a service organization operating with defined technical knowledge, appropriate equipment and consistent procedures linked to a manufacturer or product family. Wood, metal and PVC behave differently in use, so tasks such as hinge adjustment, locking performance, sealing condition and operating checks are not handled in exactly the same way for every material. A standard of this type therefore provides a shared baseline for service organization across different material categories.
