ISO 20457
In the context of , "TG5" refers to Tolerance Grade 5 , which is one of the standard accuracy levels used to define manufacturing tolerances for plastic moulded parts. Understanding ISO 20457 TG5
Without TG5 compliance, a recycled plastic is technically "un-verifiable" for high-performance use. Iso 20457 Tg5

Specifying "ISO 20457 Tg5" on a drawing is not enough to be legally enforceable. According to technical guides , a complete specification must include: : e.g., TG5. ISO 20457 In the context of , "TG5"
Title: Bridging the Gap: The Critical Role of ISO 20457 TG5 in Standardising Post-Consumer Recyclate Quality
Feedstock Dependency:
TG5 classifies output quality, but it cannot control input variability. A recycler processing municipal solid waste (MSW) will always produce lower-grade material than one processing pre-consumer industrial scrap. TG5 does not penalise or differentiate based on source—only on final properties. This means two very different environmental profiles could receive the same TG5 grade. According to technical guides , a complete specification
TG5
will likely become the most queried field for engineering plastics because it answers two critical questions for designers:
Processing Shrinkage
: The final size of a part depends heavily on its shrinkage rate. TG5 accounts for standard fluctuations in shrinkage during the cooling process.
