# Performance Specification Gap in Division 10 Specialties submittals

> Source: https://deviationcheck.com/divisions/10-specialties/performance-specification-gap/

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

## What to look for in Division 10 Specialties

Key performance parameters in specialties submittals:
- **Toilet partition material type** (HDPE, phenolic, stainless steel, powder-coated steel, solid polymer) - must match spec exactly
- **Partition thickness** (1 inch nominal for HDPE/phenolic, varies by material) and **panel height** (typically 58 inches standard, 62 or 72 inches for enhanced privacy)
- **Partition pilaster and panel gauge** for metal types (min 22ga, 20ga, or as specified)
- **Louver free area** (square feet per unit - must meet or exceed code-required ventilation)
- **Louver water penetration resistance** (tested per AMCA 500-L, rated in oz/sq ft/hr)
- **Operable partition STC rating** (Sound Transmission Class - typically STC 48-56 specified)
- **Signage luminance and contrast ratios** per ADA/ICC A117.1 (minimum 70% contrast between text and background)
- **Corner guard height** (typically 48 inches for standard, 96 inches for full-height) and **impact resistance** (measured in ft-lbs)
- **Locker tier configuration** (single, double, triple, box, or Z-style) and **ventilation** (perforated or louvered)
- **Accessory mounting heights** per ADA (grab bars, dispensers, mirrors - specific height ranges)
- **Fire extinguisher cabinet recessed depth** and rough opening dimensions
- **Flagpole height, shaft diameter, and wall thickness**

## Severity

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.
