3 Design and general requirements
3.1 Pressures
PFDs shall be designed to function at a supply pressure between 140 and 860 kPa (20 and 125 psi). In addition, PFDs shall comply with Clause 4.2.
3.2 Temperatures
PFDs shall be designed to function with water temperature between 4 °C and 30 °C (40°F and 85°F).
3.3 Backflow prevention
PFDs incorporating backflow preventers shall comply with the requirements of Clause 4.3 or 4.4. When a backflow preventer is not incorporated in the PFD, installation instructions shall identify the specific types of backflow prevention required.
3.4 Accessible designs
Operating controls intended for use in accessible designs shall
(a) be automatically controlled; or
(b) meet the following requirements:
(i) be operable with one hand;
(ii) not require tight grasping, pinching, or twisting of the wrist; and
(iii) require an operating force not greater than 22N (5 lbf)
3.5 Control stop
If the manufacturer provides a control stop with the PFD, it shall be considered part of the PFD.
3.6 Connections to water supply and fixtures
Tapered pipe threads shall conform to ASME B1 .20.1. Straight threads shall conform to ASME Bi .1.
Dimensions of solder-joint connections shall conform to ASME 81 6.18 or ASME 816.22. Compression
connections shall be compatible with SAE J51 2.
3.6.2 Outlet connections
Outlet connections shall provide pressure-tight connections to the fixture to which it is assembled, as specified in ASME Al 12.1 9.2/CSA B45.1.
3.7 Coatings
Coatings shall comply with the applicable requirements of ASME Al 12.1 8.1/CSA B125.l.
3.8 PFDs incorporating electrical features
3.8.1 (,eneral
PFDs incorporating electric features shall comply with the applicable requirements of
ASMEA112.18.l/CSA B125.1.
3.8.2 Testing
When used with a PFD, electrical plumbing controls, including solenoid valves, shall
(a) be considered components of the PFD;
(b) be tested with the PFD; and
(c) comply with Clause 4.7.
Replacement of a battery during any of the testing required by this section shall not be considered a failure of the PFD.
Section IV
4 Performance requirements and test methods
4.1 General
4.1.1 Preconditioning
Before testing, specimens shall be conditioned at ambient laboratory conditions for at least 12 h.
4.1.2 Installation for testing
For test purposes, specimens shall be installed in accordance with the manufacturer’s instructions. All intervals between discharges shall be sufficient so as to allow the PFD to complete its flushing cycle.
4.1.3 Test conditions
All tests shall be conducted using water temperatures between 4 °C and 30 °C (40°F and 85°F), unless otherwise specified in this test procedure.
4.1.4 Order of tests
Tests shall be conducted on the same specimen, in the order listed in this Standard.
4.2 Pressure test
4.2.1 Purpose
The purpose of this test is to determine if the PFD operates across its required pressure range.ASME A112.1037 pdf download.
