What standard must vinyl siding comply with according to the IBC and IRC?

1. ASTM D 256

2. ASTM D 3679

3. ASTM E 84

4. ASTM C 999

The correct answer is: ASTM D 3679

Vinyl siding must comply with ASTM D 3679, which is the standard specification for rigid polyvinyl chloride (PVC) siding. This standard covers the requirements for materials, performance, and testing methods for vinyl siding to ensure it meets necessary building safety and durability criteria. Compliance with this standard is crucial for ensuring that the siding can withstand various environmental conditions, provides adequate weather resistance, and maintains its appearance over time. This adherence helps to fulfill the building code requirements established by both the International Building Code (IBC) and the International Residential Code (IRC), ensuring that the vinyl siding is safe and reliable for use in construction projects. The other standards listed are relevant to different materials or performance aspects that do not directly pertain to vinyl siding; ASTM D 256 relates to impact resistance of plastics, ASTM E 84 is about surface burning characteristics of building materials, and ASTM C 999 covers requirements for insulation systems for HVAC applications. These are not applicable to the specific regulations governing vinyl siding.
