Indoor Air Quality
These are the standards in SynC Standards that cover Indoor Air Quality. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Standards
- Carpet
Tufted, woven, fusion-bonded, and needle-punched carpet in modular tile and broadloom formats installed over concrete, wood panel, and raised access floor substrates in commercial, institutional, healthcare, educational, hospitality, and multi-family interiors. Covers format and construction, pile configuration, face fiber and dye method, face weight, pile thickness and density, appearance retention, tuft bind and delamination strength, modular tile and broadloom backings, critical radiant flux and smoke density, static control, colorfastness, low-emitting and sustainability certification, accessibility of the walking surface, substrate acceptance for carpet including concrete moisture and alkalinity testing and mitigation, releasable adhesive, direct glue-down, double-glue, and stretch-in attachment, separate cushion, seaming, transitions, field inspection, cleaning, warranty, and attic stock.
- Dedicated Outdoor Air Systems
Factory-assembled dedicated outdoor air units that condition 100% outdoor air to a controlled leaving air dew point and supply air temperature, independent of the sensible heating and cooling of the spaces they ventilate. Covers packaged outdoor and indoor units with direct-expansion, heat pump, or chilled water cooling; hot gas, wraparound, hydronic, and electric reheat; heat pump, gas-fired, electric, hydronic, and recovery-only heating; the air-to-air energy recovery section and its exhaust side; supply and exhaust fans; filtration; casing, drain pans, and curbs; the refrigerant, its safety group, and the detection provisions that go with mildly flammable refrigerants; the supply air temperature and dew point control strategy and the unit's interface to the building automation system and to the parallel sensible system; and the setting, connection, startup, and commissioning of the installed unit. Applies to units serving variable refrigerant flow, fan coil, water-source heat pump, chilled beam, and radiant systems, to units supplying laboratory make-up air, and to units delivering ventilation air directly to occupied spaces.
- Resilient Flooring
Interior resilient floor coverings and resilient wall base in commercial, institutional, healthcare, educational, hospitality, and multi-family construction: luxury vinyl tile and plank, rigid core vinyl plank, vinyl composition tile, homogeneous and heterogeneous sheet vinyl, rubber tile and sheet, sheet and tile linoleum, resilient wall base, resilient stair treads, transition strips, and the adhesives, seam welding, integral flash cove, and static control grounding that go with them. Covers product type and class, wear layer and overall thickness, critical radiant flux and smoke density, slip resistance, static load, chemical resistance, low-emitting materials, static control resistance, substrate acceptance including concrete moisture and alkalinity testing and topical moisture mitigation, full-spread adhesive, loose lay, and floating installation, heat and chemical welding, field inspection, initial finish, cleaning, warranty, and attic stock.
