What is BS 7243-1 - Sampling Refractory Raw Materials about?
BS 7243-1 is the first part of an International Standard that discusses the method of sampling.
BS 7243-1 has been prepared under the direction of the Refractory Products Standards Policy Committee.
BS 7243-1 includes scope, normative references, definitions, general rules, sampling and sample preparation, composition and number of laboratory samples, and test portions for analysis and precision. It also contains relevant figures and tables.
Note 1: BS 7243-1 does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.
Note 2: BS 7243-1 does not apply to products in the form of large static quantities or cargoes from which reliable samples cannot be taken.
Note 3: Difficulties may be encountered when sampling certain types of unshaped products, for example, mouldables. For reduced sampling rates, see BS 1902-7.1 The scheme is unsuitable for mouldables.
Who is BS 7243-1 - Sampling Refractory Raw Materials for?
BS 7243-1 on Sampling Refractory Raw Materials is useful for:
- Steel Industries
- Electricity Supply Industries
- Materials Engineers
- Refractories
- Refractory Contractors
- Refractory Consultants and Auditors
Why should you use BS 7243-1 - Sampling Refractory Raw Materials?
As various materials used in various sectors require coating, they demand high refractory materials that can withstand high temperatures, physical wear, and chemical damage. Refractory materials that are reliable are resistant to thermal stress and physical events caused by heat.
BS 7243-1 specifies methods and conditions of sampling for raw materials and prepared unshaped refractory products. BS 7243-1 is required in order to indicate the mean values of a consignment and the interval of sampling. BS 7243-1 shall benefit the users to sample refractory materials effectively. 
These materials are used in various industries, and it is extremely important to ensure that the quality of refractory materials is ideal. BS 7243-1 can assure that standardization has been practiced. Using the guidelines of BS 7243-1  can provide you access to the best practices for sampling refractory materials.
