- 4 Construction and performance [Go to Page]
- 4.1 Product assembly
- 4.2 Dimensions [Go to Page]
- 4.2.1 The nominal diameter of the orifice of the sprinklers and the corresponding thread size of the sprinklers, except dry and flush sprinklers, shall be suitable for use with pipe threads given in Table 1. Dry and flush sprinklers may have larger thread sizes. Nominal thread sizes shall be suitable for fittings threaded in accordance with ISO 7-1.
- 4.2.2 It shall be possible for a sphere of 8 mm diameter to pass through each water passage in the sprinkler.
- 4.2.3 Sprinklers having a 20 mm nominal diameter orifice in combination with a ½ inch nominal thread size (normally used for retrofitting purposes) shall have a pintle, (10 ± 2) mm long and having a diameter of (5 ± 2) mm, permanently attached at the deflector for identification purposes.
- 4.3 Nominal operating temperature [Go to Page]
- 4.3.1 The nominal operating temperatures of glass bulb sprinklers are given in Table 2, column 1.
- 4.3.2 The nominal operating temperature ranges of fusible link sprinklers are given in Table 2, column 3.
- 4.3.3 Glass bulb sprinklers and non-plated and non-coated fusible link sprinklers shall be colour coded according to the nominal operating temperature as given in Table 2, columns 2 or 4 as appropriate.
