Gas appliances and components must be assessed under the appropriate NAG standards before import or sale. Different requirements apply to cookers, boilers, heaters, regulators and accessories.
Examples include NAG-311 (2025) for covered boilers and NAG-312, including its 2026 addendum, for domestic cooking appliances. Applicable testing, marking and documentation depend on the product and regulatory date.
We examine specifications, drawings, manuals and prior certificates, identify technical gaps and coordinate testing, technical files and follow-up with ENARGAS-recognized certification bodies.
Certification and statutory approvals are issued by authorized bodies, not by GROLL Ingeniería.
Send the product brand, model, gas type, rated output, pressures, drawings, nameplate, manual, images and available test reports.
