This will be indicated in the amendment table on theinside front cover.BS5173-103.13:1994 BSI 07-1999 1 1 Scope This Section of BS5173 describes a method to determine the resistance to fire of hose assemblies. NOTEThis Section of BS5173 does not specify the test pressure at which th
11、e tests are carried out or the minimum bend radius at which the test is to be performed. These details are specified in the appropriate hose product specification along with the period for which the test flame is to be applied and reference to grades of resistance to fire. 2 Normative references Thi
12、s Section of BS5173 incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the publications are listed on the inside back cover. Subsequent amendments to, or revisions of, any of these public
13、ations apply to this Section of BS5173 only when incorporated in it by updating or revision. 3 Apparatus 3.1 Test rig, capable of the following functions: a) mounting a hose assembly bent to its minimum bend radius, as given in the relevant hose product specification; b) maintaining a constant press
14、ure equal to the maximum working pressure of the hose as specified in the relevant hose product specification; c) with one end of the hose assembly blanked, vibrating the blanked end with an amplitude of 1.25mm and a frequency of50Hz. 3.2 Burner, calibrated in accordance with AppendixE of BS3G100-2.
15、3.13:1973 and capable of producing the flame conditions specified in AppendixA of BS3G100-2.3.13:1973. 4 Test pieces Two test assemblies with end fittings attached shall be tested. Each test assembly shall be of a length that ensures that when mounted in the rest rig the hose is bent at the minimum
16、bend radius as stated in the relevant hose product specification. 5 Conditioning No test shall be carried out within24h of manufacture. The test assemblies shall be conditioned for at least3h at standard laboratory temperature as specified in BS903-A35:1985, before testing. NOTEThe3h conditioning pe
