TS 12225

TS 12225 is a service standard dealing with general rules for workshops that manufacture doors and windows from unplasticized PVC. Its focus is not the design of the finished product itself, but the basic framework within which production should be organised. Unplasticized PVC, often referred to as rigid PVC, is a widely used plastic for window and door frames because it is stiff, durable, and suitable for building applications.

Manufacturing workshops and production organisation

The standard is centred on the general operation of the workshop or production area where door and window units are made. In practice, this involves the coordinated handling of raw profiles, cutting and processing, assembly, dimensional checks, and preparation for delivery. For rigid PVC systems, workshop order and process control are closely linked to dimensional stability, surface quality, and the accuracy of joints.

Technical context for rigid PVC joinery

Rigid PVC doors and windows are commonly selected in building joinery because they are lightweight, corrosion-resistant, and relatively easy to maintain. However, the performance of these products depends not only on the material itself, but also on accurate cutting, joining or welding operations, suitable hardware, and consistent measurement practices. General rules such as these provide a framework for making the manufacturing process controlled and repeatable.

This document covers the general principles for workshops manufacturing doors and windows from unplasticized PVC; it should not be read as an independent test standard for other window systems, other material types, or product performance classes. As a withdrawn TSE record, it is mainly useful for understanding the basic service organisation of this manufacturing activity.
