American

National

Standard

Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and

other criteria for approval have been met by the standards developer.

Consensus is established when in the judgment of the ANSI Board of Standards Review; substantial agreement has been reached

by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily

unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their

resolution.

The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone,

whether he or she has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes,

or procedures not conforming to the standards.

The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any

American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American

National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the

secretariat or sponsor whose name appears on the title page of this standard.

CAUTION NOTICE: This American National Standard may be revised or withdrawn at anytime. The procedures of the American

National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of

American National Standards may receive current information on all standards by calling or writing the American National Stan‐

dards Institute.

FOREWORD

vi LANDSCAPE IRRIGATION EMISSION DEVICE STANDARD

Introduction

In 2010, upon direction from the ICC Board of Directors, the ICC Standards Council appointed a consensus committee to develop a

standard to cover the performance, design and testing of turfgrass and landscape irrigation sprinklers.

Development

This is the first edition of the International Code Council® (ICC®) Landscape Irrigation Emission Device Standard. This standard was

developed by the ICC Consensus Committee on Landscape Irrigation Emission Devices (IS‐IEDC) that operates under ANSI Approved

ICC Consensus Procedures for the development of ICC standards. ICC is approved by ANSI as an Accredited Standards

Developer.

The meetings of the IS‐IEDC Consensus Committee were open to the public and interested individuals and organizations from

across the country participated. Views and objections were solicited through several public comment periods. All views and objec‐

tions were considered by the consensus committee and an effort was made toward their resolution. A vote by the consensus

committee approved this standard.

The technical content of currently published codes and documents on sprinklers was reviewed and considered by the committee.

While there were many similarities among the practices and documents reviewed, there were marked philosophical differences

that were considered by the committee. The requirements in ICC 802 are based on the intent to establish provisions consistent

with the scope of the ICC family of codes and standards that adequately protect public health, safety and welfare; provisions that do

not necessarily increase construction costs; provisions that do not unnecessarily restrict the use of new materials, technologies or

designs.

Adoption

ICC 802, Landscape Irrigation Emission Device Standard is available for reference and use by jurisdictions and codes internation‐

ally. Its use within a governmental jurisdiction is intended to be accomplished through adoption by referenced in accordance with

proceedings establishing the jurisdiction’s law.

Formal Interpretations

Requests for Formal Interpretations on the provisions of ICC 802‐201X should be addressed to: ICC, Chicago District Office, 4051

West Flossmoor Road, Country Club Hills, IL 60478.

Maintenance – Submittal of Proposals

All ICC standards are revised as required by ANSI. Proposals for revising this edition are welcome. Please visit the ICC website at

www.iccsafe.org for the official “Call for Proposals” announcement. A proposal form and instructions can also be downloaded

from www.iccsafe.org.

ICC, its members and those participating in the development of ICC 802‐201X do not accept any liability resulting from compliance

or noncompliance with the provisions of ICC 802‐201X. ICC does not have the power or authority to police or enforce compliance

with the contents of this standard. Only the governmental body that enacts this standard into law has such authority.

International Code Council Consensus Committee on Landscape Irrigation Emission Devices (IS-IEDC)

Consensus Committee SCOPE: The Consensus Committee (CC) on Turf and Landscape Irrigation (IS‐IEDC) shall have primary

IEDC CC.

This standard was processed and approved for submittal to ANSI by the ICC Consensus Committee on Landscape Irrigation Emission

Devices (IS‐IEDC). Committee approval of the standard does not necessarily imply that all committee members voted for its

approval.

[The intent of this test is to measure the flowrate variability of point source emitters at varying pressures.] [Microirrigation TG recommends that Packaging TG Consider: Report the average flow at each pressure and standard deviation or Cv. Chart] 404.5.1 LINE‐SOURCE FLOWRATE TEST METHOD. A length of sample line‐source emitters containing 30 emitters shall be configured in a loop and connected to a pressure source. Pressure shall be measured at the inlet to the loop and the pressure tap size and configuration shall conform to ASME PTC 19.2 or ANSI/ISA‐75.02. Water shall be supplied at a temperature between 55 – 75 °F. The loop shall be brought up to 20 psi for five minutes before initiating the test. The output of each emitter shall then be collected for a minimum period of one minute and individually recorded. Upon completion, the loop pressure shall be increased to 30 psi and run for five minutes before repeating the collection and recording process. The test pressure shall then be increased to 40 psi and run for five minutes before repeating the collection and recording process. Using volume and time, the average flowrate and standard deviation shall be calculated and reported at each test pressure, along with the average water temperature.

Chart]

404.5.1 MICROSPRAY FLOWRATE TEST METHOD. A total of 30 samples of each spray pattern shall be individually tested. Each sample shall be connected to a pressure source supplying water at a temperature between 55 – 75 F. Pressure shall be measured at the inlet to the sample and the pressure tap size and configuration shall conform to ASME PTC 19.2 or ANSI/ISA‐75.02. Each unit shall be adjusted to the fully‐opened position. The output of each sample shall then be collected for a minimum period of one minute at 15 psi and recorded. The test shall then be repeated at 20 psi and 30 psi. The average flowrate and standard deviation shall be calculated and reported at each test pressure, along with the average water temperature.
