BAS, R&Co. and P&S regret to advise that, because of the Coronavirus (Covid-19) outbreak, the companies will be closed from 24th March 2020 until further notice. 

Communications can still be sent by email to your normal company contact or to enquiries@basrid.co.uk and we shall try to answer these promptly, but there will be no despatches of goods for the foreseeable future.

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 upgraded to the International Standard ISO 17034:2016 at the beginning of 2018. Both Accreditation Certificates can be viewed by clicking on the appropriate icon below.

Over the years our website has undergone many improvements. BAS and ORM materials are searchable by name. A list of all current BAS materials and their corresponding certificates can now also be found.

We have continued the exercise to update BAS certificates to provide more comprehensive statistical information, including standard deviations 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 ORM catalogue provides details of CRMs and RMs, prepared by 27 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 ORM 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.
