60335-1(ed.3)
Standard: IEC60335-1, Ed. 3 Clause: 30 Sheet n. 264
Subject: crimp connection for internal wiring
Key words:
- plastic cap,
- crimp connection
Decision n. 20 taken at 35th meeting/1998
Question:
The figure below shows a crimp connection used for internal wiring
the plastic cap provides basic insulation.
Does the plastic cap retain live parts in position so you have to make a ball pressure test at
125°C (clause 30.1) and a glow wire test at 850°C (for unattended appliance, current more
than 0.5 amps) ?
Decision:
The plastic caps doesn’t retain in position the live parts, so the ball pressure test does not be
carried out. Subclauses 30.2.2 and 30.2.3 apply to the plastic cap, so the glow wire test has
to be carried out if the connection is carrying a current > 0,5A in normal use, for appliances
other than hand-held appliances, with the following values:
- 650°C for appliances operated while attended
- 750°C for the other appliances (except if tests of annex L are performed on the
connection)
