To achieve an classification, a recycled plastic batch must meet the following stringent threshold criteria:

According to the technical guidelines used by manufacturers like OKW Gehäusesysteme , the following tolerance ranges generally apply under TG6: Nominal Dimension Range (mm) Tolerance: Tool-Specific (W) Tolerance: Non-Tool-Specific (NW) Over 1 to 3 Over 10 to 18 Over 50 to 80 Over 180 to 250 Over 500 to 630 iso 20457-tg6

What you're using (e.g., PP, ABS, Glass-filled Nylon) The part dimensions (roughly) Whether it's a mating part or a housing/cosmetic part I can tell you if TG6 is too loose or just right. To achieve an classification, a recycled plastic batch

As we look toward 2025 and beyond, the classification will likely become machine-readable. The EU’s Digital Product Passport (DPP) initiative will embed this data into QR codes on products. A recycler in Italy will scan a TG6-rated bumper from a car, immediately knowing its viscosity, color stability, and load history. A recycler in Italy will scan a TG6-rated

Consumer goods, electronic enclosures, automotive interior trim, and structural covers.

To understand the significance of TG6, one must first grasp the overarching framework of ISO 20457. Published by the International Organization for Standardization (ISO), this standard provides principles and requirements for sustainability in infrastructure projects. Unlike building standards (such as those for green homes), infrastructure standards deal with linear, distributed systems like roads, bridges, power grids, and water networks.

Under ISO 20457, tolerances are split into tool-specific (W) and non-tool-specific (NW) dimensions. W dimensions are defined by the mold cavity (closer tolerance), while NW dimensions are affected by shrinkage, cooling, and warpage (looser tolerance).
