To help manufacturers stay on top of the ongoing changes that come with smart appliances, UL Solutions has published and offers UL 1499, a Recommended Practice for Implementing Software Updates to Appliances.

Publication of Recommended Practice

A key expectation of smart appliances involves the ability to add new functional features to existing devices through remote software updates for appliances in the field that have been purchased by consumers, such as washing machines, dryers, dishwashers, coffee makers, commercial food equipment, lighting and HVAC systems. These software upgrades enable appliances to provide enhanced value to their users. In the past, the functionality of an appliance was fixed in its initial manufacturing. As a result, appliances lost consumer value after purchase as they could not offer the latest features that newer models provided because they could not support the latest features after the initial purchase and placement in the field.

UL RP 1499 specifies recommended practices for software update process engineering practices in appliances. It encompasses the minimum elements of design, development and deployment of remote software updates. An appliance manufacturer demonstrating evidence of adhering to these recommended practices provides users with confidence that they utilize reliable methods to deploy software updates to products in the field.   

Marketing Claim Verification

The UL Verified Mark delivers the confidence to consumers that a brand’s marketing claim is accurate, truthful, and credible. UL Solutions provides a searchable database of Verified claims by brand, company name, product name and the claim’s unique identifier that help differentiate appliance products in a crowded market.
