What is ISO 21398- guidance to the inspection of mechanical sampling systems about?
ISO 21398 sets out recommended practices for the inspection of mechanical sampling systems. It serves as a guide for conformance with applicable ISO/TC 27 standards.
ISO 21398 covers general considerations including precision, mineral variability and bias,
establishment of inspection systems and inspection procedure.
Who is ISO 21398- guidance to the inspection of mechanical sampling systems for?
ISO 21398- guidance to the inspection of mechanical sampling systems is useful for:
- Coal mining industry
- Companies dealing with mechanical sampling systems
- Inspection authorities
- Mechanical sampling plants
Why should you use ISO 21398- guidance to the inspection of mechanical sampling systems?
The objective of ISO 21398 is to provide users of new and existing mechanical sampling systems for minerals with guidance on their operation and inspection.
ISO 21398 allows you to monitor coal sampling ratios using control charts and provides data collecting and charting procedures.
ISO 21398 also helps you detect out-of-control conditions and carrying out inspection at mechanical sampling plants involving large throughput of different grades of coal or
Coke. ISO 21398 helps you ensure consistent record of the sampling plant’s performance be developed and maintained.
