LPS certification programs for system installations and installers
There are programs that certify LPS for new installations and existing systems. There also are programs to certify LPS
installing contractors and LPS designers.
UL has the following programs for certifying LPS on a project-by-project basis:
Master Label Certificate. This program is for newly installed LPS. Systems that achieve a Master Label
Certificate are listed on UL's internet directory. Certificates remain valid from the time of inspection until
their expiration date (typically five years from time of inspection) unless modifications are made to:
A structure's electrical, mechanical or communication systems
Any lightning protection devices or system
Any roof system and/or coping system
Certificates may be renewed through inspection confirming adherence to current requirements.
Letter of Findings Program. Outlines inspections of LPS where a master label certificate is not possible or
cannot be verified. Projects using this program are not listed on UL's internet directory.
LPI has a related organization, Lightning Protection Institute Inspection Program (LPI-IP), that provides
inspection of LPS. The following programs are for certifying LPS on a project-by-project basis:
Master Installation Certificate. For newly installed LPS
Reconditioned Master Installation Certificate. For systems that have previously received a Master
Installation Certificate. This program typically is used when LPS components are changed or repaired or when a
previously certified systems is being recertified when LPS standards are updated.
Limited Scope Inspection Program. This program is used to verify that visible LPS components appear to be in
compliance with material and installation standards. Typically, this program is used when an existing LPS is
encountered and no or incomplete information is available about its original installation.
LPI also has programs LPS installers. Those taking the exam must be members of LPI and are retested about every
three years when the standards are updated. The testing programs are:
