What should I check about glass thickness, impact resistance, and heat stability?

What the V22 Specifications Confirm

The V22 series 12-way flush-mounted distribution box is described with a PC cover, 1.2 mm iron sheet, and pure copper busbar and terminal bars. The available product details do not specify glass thickness or provide impact-resistance ratings or heat-stability test results. These performance details should be confirmed before choosing the product.

Key Checks Before Approval

\n
• Do not interpret the 1.2 mm figure as the cover thickness: it applies to the iron sheet. The listed cover material is PC, not glass.
\n
• Request material details and test records that identify the exact V22 model and supplied materials.
\n
• Use a sample to inspect the cover and enclosure, then check that the sample corresponds to the approved product specification.
\n
• The V22 is categorized for indoor consumer-unit distribution. JUNON also lists residential and commercial uses across its product ranges.

How to Assess the Evidence

First, confirm whether the quoted version has a PC cover or a glass component. Ask how its thickness is measured and obtain the corresponding specification. For impact resistance and heat stability, request the test methods, conditions, acceptance criteria, and results. Make sure the documents and sample refer to the same model and product version being purchased.

JUNON reports that its quality process includes inspection of every unit on the production line, laboratory sampling and testing, and checks on incoming raw materials. The listed credentials include CE certification for switches and CB certification for 13A sockets. Those credentials do not, by themselves, demonstrate impact or heat performance for the V22 distribution box.

JUNON also describes contractor projects involving distribution boxes for buildings in the Philippines, Kenya, and Ivory Coast. The supplied project descriptions contain no cover impact or heat-stability test data, so request product-specific evidence for those properties.

Frequently Asked Questions

Is the V22 cover made of glass?

The supplied product information identifies a PC cover and does not list glass as a cover material.

What is the cover thickness?

No cover or glass thickness is provided. The 1.2 mm specification refers to the iron sheet.

Are impact and heat test results available?

They are not included in the product details provided. Ask for documentation covering the exact model and compare it with a sample before approval.

Recommendation

For the V22 series, confirm the cover material and thickness independently of the 1.2 mm iron-sheet measurement. Obtain product-specific test evidence for impact resistance and heat stability, since those results are not stated in the available specifications. JUNON lists a minimum order quantity of 500 pieces and a delivery lead time of 30–45 days. For technical information or assistance, contact Hayley Liao at hayley@junlang.com.
