Title: Flexible hoose.pdf
An elongation test was conducted on a Model ASH15-2025 flexible sprinkler hose with a length of 59 in. (1500 mm), considered representative of all flexible sprinkler hose discussed in this Report. The hose sample was placed in a straightening fixture and the total unstressed length was measured. This hose was then subjected to a hydrostatic pressure equal to 1.5 times the rated working pressure or 262.5 psi (1810 kPa). After a 1 minute exposure, the test pressure was released and the sample length was measured again. The flexible sprinkler hose length did not exceed 101 percent of the pre- test hose length. This result is considered satisfactory.Due to the nature of the design, the successful tests described in Section III of this Report, no other tests were deemed necessary.MARKINGThe following pertinent information is etched on the reducer of the flexible sprinkler hose:AYVAZ  ASH15-2020 or ASH15-2025  DN20  PN12  FM Approval MarkREMARKSPage 6 of 8FM APPROVALS Project ID: 30474575.1
