AMIS’s manufacture of reference materials is done according to the guidelines set out in SANS 607:2007 and ISO Guide 34:2000.
SANS 607:2007 and ISO Guide 34:2000 are the “General requirements for the competence of reference material producers” which are the general requirements in accordance with which a reference material producer has to demonstrate that it operates. The reference material producer must demonstrate that it operates with the appropriate organisation and management requirements; and with the appropriate technical and production requirements.
Representatives from AMIS sit on the National Committee of Standards South Africa TC 5140.46 (SA REMCO), in accordance with the procedures of Standards South Africa.
AMIS will generally not charge to make a Reference Material if the commissioning entity:
1) Allows AMIS to sell Reference Material's made from their material to other customers.
2) Supplies AMIS with enough raw material for three years demand for that type of Reference Material.
3) Is prepared to commit to purchase ZAR100,000 of the finished product (at the suppliers discounted price).
4) Pays for shipping to and from AMIS.
5) Requires a replacement for depleting stock.
Most of our new products are made on this basis. Alternatively customers who need sole use of their Reference Material's need to cover the full production cost. These prices are calculated on a per batch basis and depend on the batch size, the nature of the of the material, the type of analysis and the number of laboratories needed for certification.
Not if you do it in bulk and by sea freight. Freight costs are less than 1% of the price of a large batch.
Shipping costs per kg for big consignments are very reasonable. Ideally we would like a batch size big enough to satisfy the global demand for that particular Reference Material for three years. If resupply of the raw material is likely to be a problem, send enough for six years. We would rather not repeat the manufacturing exercise in less time than that.
Our production is geared up for batches between 500kg and 5000kg. We can do smaller batches, but special pricing will apply.
Making a Reference Material takes time so the honest answer is anything from under 4 months to over a year. Production time depends on the nature of the material received and the type of certification required. Some Reference Material’s are more difficult to characterise than others,
Around 60% of the production time is getting samples to the laboratories and waiting for the results. It takes longer to get laboratory results for the more difficult analytes. The state we get the raw material in also impacts production time. Wet material containing large rocks takes longer to prepare for milling.
