ICC Testing and Quality Assurance 3

Question 1

Under IBC Chapter 17, which condition requires continuous special inspection rather than periodic special inspection?

Accepted Answer

Welding of moment frame connections

Answer

Welding of moment-resisting frame connections requires continuous special inspection because the inspector must be present throughout the entire welding operation.

Question 2

What does an ICC-approved 'approved agency' mean in the context of special inspections?

Accepted Answer

An established and recognized agency regularly engaged in inspections with competent personnel

Answer

An approved agency is one with established competence and recognized status for conducting the specific inspections and tests required.

Question 3

Under the IMC (International Mechanical Code), when must duct systems be tested for leakage?

Accepted Answer

When required by the energy code or when ducts are located outside conditioned space

Answer

Duct leakage testing is triggered by energy code requirements, particularly when ducts run through unconditioned spaces where leakage causes significant energy loss.

Question 4

Which ASTM standard governs field testing of soils for compaction verification as referenced in ICC codes?

Accepted Answer

ASTM D1556 — Sand Cone or D6938 — Nuclear Gauge

Answer

Field density of compacted soils is measured using the sand cone method (ASTM D1556) or nuclear moisture-density gauge (ASTM D6938) to verify relative compaction.

Question 5

Under the IPC (International Plumbing Code), what test is required to verify the integrity of a drainage, waste, and vent (DWV) system?

Accepted Answer

Air test at 5 psi or water test to the highest point for 15 minutes

Answer

IPC requires DWV systems to be tested with water to the highest point of the system or air at 5 psi, maintained for 15 minutes without leakage.
