These standard reference asbestos (UICC)* samples "(chrysotile, amosite, anthophylite, crocidolite)" are packaged in 0.1g vials. (That may not sound like much but it is a considerable amount!). For most, it is a "lifetime" supply. These standard samples were developed specifically for calibration, testing, or reference specification for comparison with unknown materials. Use as "knowns" for SAED, EDS, XRD, and for morphological standards for TEM and SEM and sometimes even for LM. However we are unable to issue a Certificate of Conformity for these unique standard samples. SPI Supplies is the exclusive worldwide distributor for these five, one-of-a-kind standard asbestos samples.

But we can state that the origin of these five very unique and specially characterized samples was Dr. V. Timbrell, Pneumoconiosis Research Unit, Llandough Hospital, Penarth, Glamorgan, United Kingdom with the shipment being made in early 1972.

The trace element compositions of the UICC standard asbestos samples are reported in American Journal of Industrial Medicine Volume 32, Issue 6 , Pages 592 - 594, Published Online: 6 Dec 1998.

The five samples are described as follows:

Chrysotile "B" Canadian
NB #4173-111-1

This sample consists of a mixture of fiber from the firms Bells, Carey, Cassair, Flintkote, Johns-Manville, Lake, Normandie and National, proportioned roughly to represent Canadian production of asbestos products at that time. All starting materials were Grade 4 on the Canadian scale or the nearest equivalent, the goal being to obtain material of relatively short fiber length but with a minimum of "rock". For further information, see Timbrell, Gilson and Webster, Int. J. Cancer 3, 406-408 (1968). This mineral is predominantly made up of hydrous silicates of magnesia.

Chrysotile "A" Rhodesian
NB #4173-111-2

The origin of this sample was the asbestos mine located in Zvishavane (Shabani; Shavani), Matabeleland South, Zimbabwe. This mineral is predominantly made up of hydrous silicates of magnesia.

Crocidolite South African
NB #4173-111-3

The origin of this sample was the Koegas mine which was the largest asbestos mine in the Northern Cape of South Africa. This mineral is predominantly made up of hydroxy silicates of Na, Mg ,and Fe.

Amosite South African
NB #4173-111-4

The origin of this sample was the Penge mine in Northern Province, South Africa. It exhibits a lamellar, coarse to fine structure, which is fibrous and asbestiform. It consists of hydroxy silicate of Fe and Mg.

Anthophylite Finnish
NB #4173-111-5

The origin of this sample was the Paakilla mine in Finland. This type of asbestos only rarely found in construction materials. The fibers seem to be extremely flat and thin with a characteristic shape that resembles that of a knife blade, coming to a point at one end.

For further information on the use of the standards, we would suggest reading the following: J. L. Hutchison, M. C. Irusteta and E. J. W. Whittaker, High-resolution electron microscopy and diffraction studies of fibrous amphiboles, Acta Crystallographica, Vol. A31, Part 6, November (1975), p.974-801.

Special note for those contemplating asbestos analyses:
We always want to remind anyone planning to do their own analyses, at least in the USA, that there are US government approved procedures for

SPI Supplies also offers the analyst a full range of standards for microanalysis for EDS and WDS being done in an SEM or WDS being done in a free standing wavelength dispersive electron probe microanalysis system.

Packaging:
All five asbestos standards are available in glass vials.
