scope:

This International Standard provides a standard procedure for assessing and modifying performance of solids control equipment systems commonly used in the field in petroleum and natural gas drilling fluids processing.

This procedure is not intended for the comparison of similar types of individual pieces of equipment.

Clause 11 in this document replaces Clause 11 currently in the ISO 13501:2005. It specifies a different labelling requirement for shale shaker screens that will be permanently attached to the screen. It also covers the marking of shipping containers for shale shaker screens.

This International Standard Annex B provides a standard procedure for quick assessment of a solids control screen sizing. The method can be used in the field or laboratory for identification of an unknown screen approximate size range. It is provided for information only and does not replace or supplement the normative testing shown in Clauses 9 through Clause 11 in this document.

This procedure is not intended for the operating comparison or ranking of similar types of individual pieces of equipment.
