Environmental testing - Tests. Test Td: Test methods for solderability, resistance to dissolution of metallization and to soldering heat of surface mounting devices (SMD) Ingestion-build-242630 BS EN 13304 on bitumen

BS EN 13304 on bitumen and bituminous binders is useful for:

washer-type components designed to be axially loaded

sequences of data

including emergency escape lighting

ISO 5781 also provides mounting surface dimensions for pressure-reducing valves

Environmental testing - Tests. Test Td: Test methods for solderability, resistance to dissolution of metallization and to soldering heat of surface mounting devices (SMD) Ingestion-build-242630 BS EN 13304 on bitumen1 Scope This part of IEC 60068 outlines test Td, applicable to surface mounting devices (SMD). This document provides procedures for determining the solderability, resistance to dissolution of metallization and resistance to soldering heat of devices in applications using solder alloys, which are eutectic or near eutectic tin lead (Pb), or lead free alloys. The procedures use either a solder bath or reflow method and are applicable only to specimens
