According to resolution 92 / 98, which came into force in 1998, Argentina implements S-Mark compulsory certification for electronic and electrical equipment with input voltage in the range of AC 50-1000 VAC or DC 50-1500 VDC. The resolution divides the products into four groups and has been implemented step by step since 2001. By August 1, 2004, all products must obtain S-Mark certification before they can enter the Argentine market. Argentina is a member of CB system, and CB certificates and reports are recognized, which can save a lot of trouble of repeated testing and sending samples. Argentine S-Mark safety certification does not need to arrange factory inspection. The applicant shall provide nameplate (including safety warning mark) and operation manual in Spanish. The certification authority's mark shall be added next to the S-Mark mark mark.
