BS EN ISO 3506-3:2009 Mechanical properties of corrosion-resistant stainless steel fasteners. Set screws and similar fasteners not under tensile stress
BS EN ISO 3506-3 specifies the mechanical properties of set screws and similar fasteners not under tensile stress made of austenitic stainless steel, when tested over an ambient temperature range of 10 °C to 35 °C. Properties vary at higher or lower temperatures. BS EN ISO 3506-3 applies to set screws and similar fasteners:

With nominal thread diameter 1,6 mm u d u 24 mm; Of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262 Of any shape.

It does not apply to screws with special properties, such as weldability. Contents of BS EN ISO 3506-3:
