scope:

This Standard specifies testing methods, performance requirements, and data to be supplied by the manufacturer for collapsible emitting hose products with discrete emission points along their lengths, commonly referred to as "drip tape," and herein referred to as "collapsible emitting hose."

This Standard applies to collapsible emitting hose intended for irrigation of which the emitters form an integral or permanently attached part. It does not apply to tubing which is porous along its entire length.

This Standard applies to specifications and performance testing for newly manufactured collapsible emitting hose products.

While it is recognized that resistance to emitter plugging is an important consideration in the selection and comparison of collapsible emitting hose products, emitter plugging is not covered in this standard because a repeatable test representative of the variety of field conditions encountered in typical applications is not available.
