CERTIFICATES for BAS Materials

Certified Reference Materials (CRMs) for both chemical and spectroscopic analysis are prepared and issued by the BUREAU OF ANALYSED SAMPLES LTD (BAS) . The company was formed in 1935 to ensure the continuation of the work of the British Chemical Standards (BCS) Movement which was started in 1916 as an informal association of chemists in the iron and steel industry.

The first British Certified Reference Materials were produced initially with the assistance of NBS (now NIST) in the USA and the work has continued under the guidance of an independent Honorary Advisory Committee consisting of experienced Analysts from the iron, steel, non-ferrous alloy and mineral industries.

The finely divided (chip or powder) samples for chemical analysis (BCS-CRMs and EURONORM-CRMs) include a wide range of plain carbon and alloy steels, cast irons, ferro-alloys, non-ferrous alloys, ores, slags and ceramic materials.

The solid (disc or block) samples for spectroscopic analysis (SS-CRMs) cover most plain carbon, low alloy and highly alloyed steels, cast irons, and some non-ferrous alloys. Setting-up Samples of carbon and low alloy steels, and of cast irons, are also available.

As a complementary service, we distribute Certified Reference Materials prepared by other reputable Producers.

In addition to work directly concerned with the preparation of Certified Reference Materials, we are also actively engaged in work for various technical committees of BSI, ISO and National Research Associations developing methods of analysis.

The Bureau of Analysed Samples Ltd. (BAS) has been producing Certified Reference Materials for over eighty years. A large range of CRMs have been developed and maintained over this period, all under the auspices of an Honorary Advisory Committee and a body of approximately 150 Co-operating Analysts representing both Independent Laboratories and Manufacturers and Users of the materials concerned.

In November 1994, the Quality System of the Bureau of Analysed Samples Ltd. was formally approved and recognised by the award of a Certificate of Registration to the Quality Standard BS EN ISO 9002:1994 for the production and supply of CRMs, RMs and SUS. This certificate was most recently re-validated, in September 2017, to the new Standard BS EN ISO 9001:2015. Furthermore, BAS was accredited, in June 2006, to the International Guide, ISO Guide 34:2000 and this accreditation was recently upgraded to the International Standard ISO 17034:2016 earlier this year. Both Accreditation Certificates can be viewed by clicking on the appropriate icon below.

Over the years our website has undergone many improvements and now includes a database of our current range of CRMs, together with the more popular OSRM materials. This is simultaneously searchable for up to six constituents. Products and their corresponding Certificates are now also searchable by name.

We have continued the exercise to update BAS certificates to provide more comprehensive statistical information, including standard deviation and half-width confidence intervals where these did not previously exist. Please check the Numerical Index on pages 25-28 of the BAS Catalogue to ensure that you have the latest certificate. If you have not, then please check this website for our selection of current certificates. If you are unable to locate a current certificate then we will gladly supply it on request.

Our OSRM catalogue provides details of CRMs and RMs, prepared by 28 reputable producers, and many of these are retained in our stock at Newham Hall for prompt despatch, and those which are not immediately available from our stock are usually obtainable from the Producer concerned within two weeks.

If CRMs and RMs of specifications not covered in our BAS and OSRM Catalogues are sought, we are very happy to search for any such sample which may be known to us through our personal worldwide database.

BAS is proud to be one of the first RM Producers to gain accreditation to the new International Standard ISO 17034. We strive to continually provide the quality of products and service for which this award was gained.
