The glow wire test has to be performed over the shielding and shielded materials joined together, at the point the connection is made, at 750°C, from the inside to outside as normal testing, allowing the tip to penetrate the shielded material. In this case, the shielded material is the external plastic case because it is within 3mm from the connection (as in the figures).
