Only VdS Approved pendent spray sprinklers of 10-mm, 15-mm, and 20-mm nominal diameters with
K-factors of 57, 80, and 115 shall be used.
• Tested with a 5 3/4-inch/146-mm length straight reducer.
• When using a No. 101 90° Elbow or a No. 102 Straight Tee in place of a Style 108 Coupling on
the end of a Series AH1-CC or AH2-CC Flexible Hose, the friction loss data shown above shall
be added to the No. 101 or No. 102 friction loss data published in Victaulic
• Flexible Hoses are VdS Approved for use in wet systems only.
NOTE: The VdS Approval applies only for use with specific suspended ceiling systems. Refer to the
"Construction Requirements" section of this handbook.
• Other manufacturers' ceiling systems, with comparable or better performance, can be
considered for approval.
• VdS standards for safety include, but are not limited to: pressure cycling, corrosion resistance,
flow characteristics, vibration resistance, leakage, mechanical strength, and hydrostatic
strength.
• Differences in equivalent lengths are due to varying test methods, per FM 1637 and VdS
standards. Refer to these standards for additional information regarding friction loss test
methods.
