Essential tests before bringing a connected product to market

Essential tests before bringing a connected product to market

Connected objects, communicating industrial equipment, home automation devices, IoT systems—all these products share a common feature: before they can be marketed, they must demonstrate compliance with applicable regulatory and technical requirements.

For manufacturers, the stakes are twofold: ensuring the product's safety and proper functioning while securing market access. This involves several rounds of laboratory testing.

1. Electrical safety: protecting users

Electrical safety is one of the first steps in evaluating a connected product. The goal is to verify that the equipment poses no risk to the user under normal operating conditions or in the event of a foreseeable fault.

Tests may cover aspects such as :

• Protection against electric shock
• Component heating
• Insulation distances
• Mechanical strength
• Risks associated with the power supply

These checks help ensure product safety throughout its entire lifecycle.

2. Electromagnetic compatibility (EMC): avoiding interference

A connected product rarely operates in isolation; it must coexist with a multitude of other electrical and electronic devices. Electromagnetic compatibility (EMC) testing verifies that the product:

• Does not generate excessive interference
• Is itself resistant to interference from its environment
• Maintains its performance under real-world operating conditions

A failure to meet EMC compliance standards can lead to malfunctions, service interruptions, or difficulties in accessing the market.

3. Radio testing: ensuring reliable communication

Wi-Fi, Bluetooth, Zigbee, LTE-M, 5G, NFC—radio technologies are at the heart of many connected products today. Radio testing aims to verify:

• Communication quality
• Transmission power
• Efficient use of the radio spectrum
• Compliance with applicable regulatory requirements.

These evaluations are essential to ensure product performance and market acceptance.

4. Environmental testing: validating product robustness

A product that meets standards in the laboratory must also perform well in its actual operating environment. Environmental testing assesses how the product handles various stresses, such as:

• high or low temperatures
• humidity
• vibration
• mechanical shock
• accelerated aging.

These tests provide a concrete picture of product reliability and help reduce the risk of field failures.

5. Performance testing: confirming product claims

Beyond regulatory requirements, manufacturers also want to demonstrate their products' performance. Depending on the technologies involved, testing can evaluate:

• communication quality
• battery life
• transmission speed
• operational stability
• specific performance metrics expected by users

These measurements verify that the product meets the objectives set during the design phase. A comprehensive approach to secure market launch: project success relies not on a single test, but on a combination of complementary evaluations performed at the right stages of development.
