CSI MasterFormat and Division 07: materials, standards and design constraints
How a three-part section is organised and what two real flashing sections (a federal guide specification and a utility's) pin down: metals, minimum thicknesses, piece lengths, joint spacing, cleats and ES-1 references, set against AFS limits.
You will be able to: Identify the standards, metals, thicknesses, lengths, joint spacings and performance references a Division 07 flashing section places on a fabricator, and say whose value each one is.
NIBS's SpecsIntact help says Part 1 General covers the administrative and procedural requirements unique to the section.
NIBS's SpecsIntact help says Part 2 Products describes the quality of items required for the job.
Part 3 Execution covers preparation and how the products are used.
Missouri's format guide says every SectionFormat article is optional and an unused Part is marked Not Used.
Three stacked panels listing the article headings in Salt River Project's Section 07 62 00 under Part 1 General, Part 2 Products and Part 3 Execution, with a box noting Division 01 holds the procedures, that UFGS Part 1 points to 01 33 00 and VA's to 01 33 23, and that this utility's section names neither.

Headings from one utility's real 07 62 00 (August 2021). SectionFormat articles are optional, so another section may use fewer or different ones. Box D compares UFGS 07 60 00 (August 2023) and VA 07 60 00 (October 2023) with this utility's section.
The part of a section covering the administrative and procedural requirements unique to that section, such as submittals, quality assurance, delivery and warranty.
Minimum thickness
A metal thickness a section states as the least allowed. SRP's section adds that a thicker metal must be provided where the sheet metal standards recommend it.
Cleat
A strip of metal fastened to the substrate that a flashing edge hooks onto. UFGS asks for cleats on sheet 18 inches and wider, spaced not over 12 inches on center unless otherwise specified or indicated.
Expansion and contraction joint
A joint in continuous sheet metal that lets thermal movement happen. The maximum spacing is each section's own requirement.
ES-1
ANSI/SPRI/FM 4435/ES-1, an edge-system test standard that specifications name when they want tested copings and roof edge flashing. A rating belongs to the tested assembly.
