ANSI CAN IAPMO Z1349 pdf free download.Devices for Detection, Monitoring or Control of Plumbing Systems.
Environmental Conditions — State of the area surrounding the device including ambient temperature, humidity, and occupancy.
Metering Device — A device that measures water flow through a water pipe, that tracks volume of water used. A metering device may send a signal when pre-set conditions are met.
Micro Leak — A water leak having a flow rate of 14 mI/h (0.5 oz/h) or less.
Monitoring — Ongoing analysis of sensor readings including pressure, temperature (ambient or water), flow rate or system conditions.
Note: “Smart devices” typically provide the information gathered from sensor readings to the user of the system and an integrated or remote CPU for monitoring, analysis, and feedback.
Non-Invasive Monitoring Device — Measures the system conditions (e.g. water temperature, and flow) without penetrating through the exterior of the system or encountering the internal water.
Physical Water/Moisture Detection Device — Senses water or moisture in specific locations through contact and sends a signal when activated to a receiving device.
Note 1: Once the receiving device gets a signal, it typically takes an action such as alerting maintenance, triggering a noise, system alarm or silent alarm, or when attached to an automatic control valve turning- off the water supply.
Note 2: Detection devices can use an electronic circuit that is normally open but becomes closed in the presence of or through contact with water.
Potable Water — Water that is satisfactory for drinking, culinary, and domestic purposes and that meets the requirements of the Health Authority Having Jurisdiction.
Remotely Controlled Valve — A valve that can be controlled from a remote location using an electronic device such as a computer or cell phone.
System Integrity — The health of a plumbing system as defined by the system operating within the normal/rated pressure, temperature, and flow ranges.

4 General Requirements
4.1 General
Devices covered by this Standard shall perform at least one of the following:
(a) Detect the presence of water or moisture.
(b) Detect abnormal water flow patterns as defined by the manufacturer.
(c) A metering function (e.g., metering device).
(d) Monitor system conditions (e.g., water temperature, pressure, and flow).
(e) Monitor environmental conditions.
Note: In addition to detection or monitoring covered in Section 4.1, devices may provide hard wired or
remote access to notify the user of abnormal system conditions or/and to control a valve.
4.2 Joints and Connections
Devices covered by this Standard shall be capable of connecting with pipes, tubes, hoses, or other plumbing components for the intended application. The components for the joints and connections of these devices into the plumbing system shall comply with the performance requirements of their applicable standards.
Note: Other devices, such as non-invasive monitoring devices or physical moisture/water detection devices do not require connection in the plumbing system.
4.3 Materials
4.3.1 Bodies and Operating Parts
Bodies and operating parts shall be made of materials that are compatible with other components of the device assembly and of the plumbing system, if applicable, and shall be corrosion resistant.
4.3.2 Copper Alloys in Contact with Water
All copper-alloy components in contact with water containing more than 15% zinc (Zn) by weight, shall be subject to the dezincification and stress corrosion testing specified in Section
5.2.
4.3.3 Stainless Steel Components
Stainless steel alloys in contact with water shall be resistant to stress corrosion. There shall be no evidence of cracking when tested in accordance with ASTM G36 using complete immersion under a stress of 862 kPa (125 psi) for 24 hours.ANSI CAN IAPMO Z1349 pdf download.
