How Windspro Helped a Pizza Oven Pass New Temperature 

Rise Requirements Without Sacrificing Performance

When safety standards suddenly change, electric heating products need rapid optimization. Here's how Windspro handled it.

1. Customer Background

    -Region: Europe

    -Customer Type: Well-known local distributor of niche party home appliances

    -Product: Home pizza oven

2. The Challenge

Since 2013, the A13 amendment (EN 60335-2-9/A13:2010) specifically introduced reduced surface temperature limits for accessible "non-functional" surfaces of portable cooking appliances (grills, toasters, etc.) to prevent burns.

Surface Temperature Limits: The standard sets maximum permissible temperatures for various accessible parts of an appliance (e.g., handles, control knobs, main enclosure) to prevent injury. The exact limits depend on the material (metal, plastic, glass, etc.) and the part's function.

For example:

Due to this requirement for non-functional surface temperature rise, almost the entire market simultaneously began reducing product power. 

This meant that electric heating products across the European market would become slower, with lower heating surface temperatures. 

The customer was concerned that if forced to reduce power, their product's competitiveness would be leveled down to match competitors. 

This ceramic-lid pizza oven's key selling point was that the ceramic's heat retention capability made pizza taste better.

The customer's main concerns and challenges were:

    1. Must ensure compliance to continue sales and maintain market share

    2. No existing market solutions could maintain heating performance while passing external temperature requirements

    3. Already approaching June, missing the September launch would mean losing the year's peak season

The customer sought an OEM partner willing to invest time in serious research, improve the product without changing its appearance, 

enable mass production, and keep the product line running without significantly increasing costs or R&D investment.

3. Our Solution

Based on the existing structure, we optimized in several areas:

Structure and Control Method Adjustments:

    (1)Added insulation layer structures and optimized heating element power distribution

    (2)Fine-tuned external housing material and shape to create more heat dissipation space while maintaining appropriate internal temperatures

Electrical and Insulation Design Upgrades:

    (1)Adjusted internal wiring paths and added insulation protection at critical points

    (2)Fine-tuned the thermostat to implement cyclic control of surface temperature

Joint Laboratory Pre-Assessment:

    (1)Before mass production, we conducted multiple pre-inspections according to the new GS standards

    (2)Repeatedly verified temperature rise, pressure resistance, leakage current, and other items to reduce the risk of inspection failure

4. Results and Data

    (1)The product successfully passed the third-party laboratory GS's new standard certification

    (2)Total cycle from project initiation to testing approval was controlled within the customer's acceptable time window

    (3)Maintained original pizza baking performance and appearance design while controlling costs

    (4)No safety-related returns or complaints occurred during subsequent batch shipments

For customers with established brands who need to respond quickly to new standards, we can:

    (1)Assess how far existing structures are from new standards without starting from scratch

    (2)Provide integrated improvement solutions covering structure + materials, + electrical

    (3)Reduce risks of repeated testing and delayed market entry

5. Summary and Recommendations

This case demonstrates how to respond quickly when regulatory standards suddenly change, while maintaining the product's core competitiveness. 

For customers facing similar challenges, we recommend:

    (1)Monitor standard updates proactively: Learn about upcoming new standards early to allow sufficient time for product optimization

    (2)Choose partners with R&D capabilities: Not just manufacturing ability, but also capacity for customized design improvements targeting specific standards

    (3)Prioritize laboratory pre-assessment: Conducting multiple rounds of internal testing before official submission can significantly reduce certification failure risks and time costs

    (4)Balance performance and compliance: Don't sacrifice the product's core selling points just to pass testing—seek solutions that achieve both
