Who is required to evaluate concentrate samples taken during periodic inspections?

• A. The customer
• B. The installer
• C. The distributor
• D. The manufacturer

Answer: (D)

The party responsible is the manufacturer. They own the product specifications, testing methods, and acceptance criteria for the concentrate, and they have the laboratory resources needed to analyze samples and determine whether the concentrate still meets listing and performance requirements. When a concentrate sample is taken during periodic inspections, sending it to the manufacturer for evaluation ensures that any aging, contamination, or degradation is accurately assessed against the exact standards the product was designed to meet. This arrangement provides consistent, authoritative judgment on whether the concentrate remains suitable for use. While customers, installers, or distributors may collect samples or perform routine checks, they typically don’t have the validated testing protocols or the official criteria to authorize continued use. The manufacturer’s evaluation ensures safety, compatibility, and compliance with the product’s approved specifications.
