Manufacturers can provide an anti-corrosion plastic distribution box sample for quality checks and performance evaluation. However, the available product information does not state that aging tests are automatically included in the standard sample service. For the V22 series 12 way flush mounted distribution box, buyers should confirm the aging-test scope and acceptance requirements before approving the sample.
The V22 is an indoor consumer unit distribution box designed for flush-mounted installation. Its listed components include a PC cover, a 1.2 mm iron sheet body, a pure copper busbar and terminal bars. Although these materials describe the product structure, they do not by themselves establish a specific anti-corrosion level or confirm resistance to long-term aging.
The current product data does not identify an aging-test standard, exposure environment, test duration, inspection procedure or pass/fail threshold. Therefore, a buyer requesting this evaluation should define the required conditions in advance. These may include temperature and humidity exposure, ultraviolet exposure or other project-specific conditions, together with the inspection points and acceptance criteria.
The manufacturer reports a quality-control process that includes inspection of every item on the production line, laboratory sampling and testing, and incoming inspection of raw materials. Its manufacturing resources also include more than 30 professional testing equipment sets and a team of over 30 engineers and designers.
The company lists CE certification for switches and CB certification for 13A sockets. These certifications relate to the indicated product categories and should not be treated as direct evidence that the V22 distribution box has completed a particular aging test.
Project records also reference distribution-box applications supplied to contractors in the Philippines, Kenya, Ivory Coast, Kazakhstan, Uzbekistan and Sri Lanka. Such records indicate use in building projects, but they do not provide the aging-test conditions or results for the V22 sample.
| Evaluation Area | Information Currently Available | Details to Request |
|---|---|---|
| Sample service | Available for quality inspection and performance evaluation | Confirm the sample configuration, quantity and testing timetable |
| Aging evaluation | No standard aging test is specifically listed | Confirm availability, test method, exposure conditions and acceptance criteria |
| Materials and structure | PC cover, 1.2 mm iron sheet, pure copper busbar and terminal bars | Verify corrosion-resistance requirements for the intended installation environment |
| Factory quality control | 100% line inspection, laboratory sampling and incoming-material inspection | Request inspection records or reports applicable to the sample |
| Commercial reference | Product record states a 500-piece MOQ and 30 to 45 day delivery period | Confirm sample pricing, production terms and mass-order schedule |
The available information confirms quality inspection and performance testing, but it does not confirm aging testing as a routine sample service. The manufacturer should provide written confirmation of whether the requested aging evaluation can be arranged.
The stated construction uses a PC cover, a 1.2 mm thick iron sheet, pure copper busbar and terminal bars.
The listed controls include 100% production-line inspection, laboratory sampling and testing, and incoming inspection of raw materials.
The request should specify the applicable standard, environmental exposure, test duration, inspection points and acceptance limits. These items should be agreed before the sample evaluation begins.
The V22 series sample can support the documented quality and performance checks, but the supplied product record does not prove that aging testing is included. Before confirming the sample, ask the manufacturer to state whether aging testing is available and to provide the method, conditions, duration and acceptance criteria in writing.
The broader business information supports mixed-item orders in a 20-foot container or orders of 500 pieces per model, with a general delivery estimate of 45 to 60 days. The individual product record separately lists a 500-piece MOQ and a 30 to 45 day delivery time, so these terms should be reconfirmed for the specific project.
