About BS 3247:1991

When buying rock salt, it’s important to only buy rock salt that’s been tested and recognised by the British Standards Institute. BS 3247 : 1991 is the certificate given to rock salt that has met these standards, and all rock salt sold by Online Rock Salt meets these standards.

The industry-wide standard ensures that the salt supplied has less than 4% moisture content, and is of the correct thickness for accurate spreading. Ensuring that your rock salt has BS 3247 : 1991 somewhere on the packaging means that the rock salt is fit for purpose. Although this system is entirely self-regulating, it does help commercial buyers of rock salt know that they are getting the most appropriate grit salt for de-icing.

The British Standards Institute was formed in 1901 as an effort to standardise production within the steel industry. Although some of their specifications are being slowly superseded by European standards, these standards mean that you can be certain that you’re receiving goods that are up to industry standards. For the code BS 3247 : 1991, the initial four numbers refer to the code for the product, whilst the last four digits refer to the year that the standard was brought in.
