Safety shoes class S3 SRC (slip resistance C)

Safety shoes may contain different standards, denoted by an S code. These run from one to five. S3 safety shoes are the most common and are a combination of S1 and S2 certified safety shoes. S3-rated safety shoes are therefore waterproof, anti-static and absorb energy in the heel. They also have both a safety toecap and a safety sole. The S3 safety standardisation states that this safety shoe also suffices in multiple working conditions and is therefore versatile regarding safety and comfort. This is why this type of safety shoe is the most commonly used.

Apart from the S-coding, standards can contain additional terms, which indicate that the safety shoes meet additional (specific) requirements. For instance, there are different requirements regarding the slip resistance of the safety shoe. For soles, this is laid down in EN ISO 345. The slip resistance is tested on different (compound) surfaces and in combination with different liquids. The outcome of these tests determines the standardisation. In total, there are three types of standardisation for slip resistance: the SRA, the SRB and the SRC. The SRA involves testing a ceramic tile liner with a soap solution called lauryl sulphate. For an SRB rating, testing is done on a steel/metal surface with glycerol. If the safety shoe offers sufficient slip resistance in these conditions, it can be certified with that standard. The SRC looks at both the test from the SRA standard and the test belonging to the SRB standard. If the safety shoe passes both tests, it is marked with an SRC standard. Thus, it can be said that SRA plus SRB leads to the SRC standard. This standard involves the SRC and thus contains the most slip-resistant standard for safety shoes.
