PFS4 Belt Scale Achieves Type Approval in Zambia
The Precision Fully Suspended (PFS4) belt scale achieving type approval in Zambia marks an important milestone in CST’s ability to delivering legal-for-trade measurement across Africa. As regulatory frameworks continue to evolve, mining and bulk material handling operations are increasingly required to demonstrate not only performance, but verified measurement accuracy that meets local and international standards.
Type approval confirms that a system has been independently assessed and meets strict legal standards for trade use, and it can now undergo formal legal-for-trade assessment once installed on site. Particularly for export operations like ports, this provides a level of assurance that measurement data can be relied upon in commercial transactions, audits and reporting processes.

In practice, belt scales must perform consistently across varying throughput, material characteristics and environmental conditions. This is particularly relevant in African operations, where conditions can change significantly across sites and seasons.
The PFS4 belt scale is designed to address these challenges, delivering stable measurements that supports both operational control and regulatory compliance. With better scale accuracy operations can reduce the risk of discrepancies between measured and actual tonnes, improving commercial decision-making.
As operations move towards tighter compliance requirements, type-approved belt weighing systems are a great way to guarantee your site is getting the verified measurement it needs to operate at peak efficiency.
