Standard ISO 1133 uses a 2.16 kg weight. TG5 allows for 5kg or 10kg weights (Condition M).
Given the lack of specific information on "ISO 20457 Tg5," here's a generic example of what a text might look like if we were discussing the importance of international standards:
"International standards, such as those provided by the ISO, play a crucial role in ensuring that products, services, and systems are safe, reliable, and of good quality. They help organizations to operate efficiently and effectively, facilitating the exchange of goods and services across borders. By adhering to these standards, businesses can gain a competitive edge, improve their reputation, and reduce the risk of errors or failures."
If you are building a "Smart City," you use TG5 standards (specifically ISO 14813) to ensure your investment isn't wasted on proprietary systems that can't talk to each other later. It provides a neutral, standardized blueprint for tenders.
