A NEW rugged and rapid-throughput tester for quality testing wire
terminal strength is available from Mecmesin Ltd. Simple controls
combine with accuracy and ease of use to make the CrimpTest-1
kN a high-reliability everyday tester, requiring minimal training and
maintenance.
Motorised pull testers improve accuracy and reduce operator
strain and injury. For added safety, this ergonomically designed
horizontal tester pulls samples away from the user. A single button
press runs a test, and just four multi-function buttons provide for
all settings, operation and output to an RS232 statistical printer.
Peak force at break is displayed along with clear pass and fail
indication. Four speed settings are available: 25, 50, 100 and 200
mm/min, to comply with all regular test standards. Units of force
can be displayed in N, kgf or lbf.
This bench tester is designed for continuous use within the
production environment, and is IP52 rated against ingress from
dust, wire fragments and water.
Versatile fixtures are available for pull testing crimped, soldered or
welded terminals, and cable ties, to 1 kN:
• Slotted rotary crimp receptacle with stepped loop pin (standard)
• Self-tightening cam grip (standard)
• Wedge grips for flat or round terminals (optional)
• Cable tie fixture (optional)
Applicable international test standards:
• ASTM B913: Standard test method for evaluation of crimped
electrical connections to 16-gauge and smaller diameter
stranded and solid conductors
• SAE AS39029 and AS7928: general specification for terminals,
lug: splices, conductor: crimp style, copper
• IEC 60352-2: solderless crimped connections
• BS 5G 178 (Part 1): crimped joints for aircraft electrical cables
and wires
• DEF STAN 59-71: crimped electrical connectors for copper
conductors
• ISO 1966: crimped joints for aircraft electrical cables
• NASA-STD-8739.4: space applications, crimping, cabling and
harnessing
