For specifiers
Writing a spec under 09 67 23
There is no dedicated MasterFormat section for resinous static control flooring. The one static control number, 09 65 36, covers resilient tile and sheet goods, which is a different product[13]. A resinous ESD system is written into 09 67 23 Resinous Flooring, with its ESD performance stated in Part 2.
Writing the specification
Name the band, not the adjective
'Static control epoxy' is not a specification. The band, the test method and the standard your program runs to are what make it enforceable at closeout.
Specify the system, not the topcoat
Manufacturer warranties are generally tied to installing the full specified system, primer, basecoat and topcoat, rather than a substituted product in the middle. Say so in Part 2 or a substitution will arrive at bid.
Put the moisture test in the spec
ASTM F2170 slab relative humidity readings, taken in situ at the locations and density you want, before installation[12]. If it is not specified it becomes a change order the week work starts.
Say what gets handed over
Product data, the system cross section, the surface prep profile, moisture readings and a grounding drawing. Naming the closeout package in the spec is what makes it exist.
Reference the program, not just the product
Cite ANSI/ESD S20.20[1] or IEC 61340-5-1[6] explicitly. It tells every bidder which world they are in and which test methods apply.
Write the reverification in
ESD TR53 covers compliance verification for items already in service[17]. A spec that ends at day one hands the facility an unowned obligation.
The performance lines to write
Copy these into Part 2. A specification that says "ESD epoxy" and stops cannot be enforced against anybody, including us.
| Line | What to specify | Cite |
|---|---|---|
| Resistance band | 2.5 x 104 to 1.0 x 106 ohms (conductive) or 1.0 x 106 to 1.0 x 109 ohms (dissipative) | ANSI/ESD STM7.1 |
| System resistance | Under 1.0 x 109 ohms, person plus footwear plus floor | ANSI/ESD STM97.1 |
| Walking voltage | Under 100 volts | ANSI/ESD STM97.2 |
| Slab moisture | Under 80 percent internal RH | ASTM F2170 |
| Vapour emission | 8 to 10 lbs / 1,000 sq ft / 24 hr | ASTM F1869 |
| Program standard | ANSI/ESD S20.20 or IEC 61340-5-1 | Name the one you run to |
| Section | 09 67 23 Resinous Flooring, Part 2 performance | CSI MasterFormat |
Questions
Which CSI section does resinous ESD flooring go under?
09 67 23 Resinous Flooring, with the ESD performance written into Part 2. 09 65 36 Static-Control Resilient Flooring is a different product category, resilient tile and sheet, not a resinous coating[13].
What is the minimum enforceable ESD line in a spec?
A resistance band, a test method, and the program standard. Those three make it possible to accept or reject the finished floor on evidence rather than opinion.
Should the spec name a manufacturer?
That is your call as the specifier. What matters more is that the performance lines are written so any compliant system can be measured against them. Send us the draft section and we will tell you what a bidder will read into it.
