Iso 20457: Tg5 [verified]

Unlike virgin plastics, recyclates absorb moisture heterogeneously. TG5 specifies drying cycles that account for the talc layer, which can trap moisture.

This grade is designed for parts where general dimensional accuracy is required without reaching the extreme costs of high-precision manufacturing. Iso 20457 Tg5

To verify "PP + 30% Talc" recyclate:

“The non-destructive X-ray CT scan. Clause 4.2.3. The porosity ratio is 0.04% above the TG5 limit.” The porosity ratio is 0

The standard categorizes tolerances into groups (TGs) ranging from TG1 (ultra-precision) to TG9 (coarse). is often the baseline for "standard" industrial production where extreme precision is not required, but assembly and function must remain consistent.

: Standard Baseline Precision. This is the "default" for technical parts where fit and function are important but not microscopic.
