Can someone explain what "srapnelovy" is?

[Shell Shifter]

Here is a chart showing the round in question. It translates as shrapnel but it ain't that. These rounds are for signaling. I am thinking a flash bang or mortar projectile. Anyone?

26.5 mm signal shrapnel cartridge – 26.5 – Sig Š:
It is a training aid designed for day and night signaling and for showing low sprays.
The explosion occurs at a height of min. 65 m. The flash and the resulting white cloud are visible during the day at a distance of at least 1 km, the sound (blow) is clearly audible up to a distance of 5 km.
The firing of 26.5 mm signal cartridges is carried out using a 26.5 mm signal gun vz. 44/67.
