6.3 certificate<br />
6.3.1 <strong>VSH</strong> <strong>Press</strong> Sprinkler Galvanized <br />
The <strong>VSH</strong> Sprinkler Galvanized system has a FM certification for fittings<br />
and tubes according the FM approval standards 1630 and 1920 for the<br />
application in wet sprinkler systems with a maximum pressure of 175 psi<br />
(12,1 bar). The approval refers to the <strong>VSH</strong> <strong>Press</strong> Sprinkler system in the<br />
dimensions DN20 to DN50 (22-54 mm). According FM the system is<br />
certified for using <strong>VSH</strong> <strong>Press</strong> Galvanized Sendzimir tubes. No limitations on<br />
hazard classes, when using <strong>VSH</strong> <strong>Press</strong> Sprinkler Galvanized, apply when<br />
installing according to FM standards.<br />
6.3.2 <strong>VSH</strong> <strong>Press</strong> Sprinkler Stainless <br />
The <strong>VSH</strong> Sprinkler Stainless system has a FM certification for fittings<br />
and tubes according FM approval standard 1630 and 1920 for application<br />
in wet and dry sprinkler system with a maximum pressure of 175 psi<br />
(12,1 bar). The approval refers to the <strong>VSH</strong> <strong>Press</strong> Sprinkler system in the<br />
dimensions DN20 to DN100 (22-108 mm). According FM the system is<br />
certified for using <strong>VSH</strong> <strong>Press</strong> stainless steel tubes with material code 1.4401<br />
(AISI 316), 1.4520 (AISI 439) and 1.4521 (AISI 444). No limitations on<br />
hazard classes, when using <strong>VSH</strong> <strong>Press</strong> Sprinkler stainless, apply when<br />
installing according to FM standards.<br />

6.3.3 Assembly and Installation of approved sprinkler installations<br />
The assembly and installation of the <strong>VSH</strong> <strong>Press</strong> Sprinkler system may only be performed by<br />
trained technical personnel who are qualified to work on sprinkler systems. When making a<br />
transition from traditional thick wall tubes to the <strong>VSH</strong> <strong>Press</strong> Sprinkler system in the dimensions<br />
DN20 to DN50 (22-54 mm), it is mandatory to use a transition from press to grooved coupling<br />
(product group C 1442 and R 2748).<br />
When installing the transition coupling from press to grooved, always make sure to use the<br />
complete insertion depth of this specific fitting. The minimum insertion depth for this fitting can<br />
be found in the table below.<br />
