So who is correct? There are so vw standards to adhere to and each manufacturer might have different requirements. Pleased to meet you at electronica in November, Traditionally, autumn is time to harvest and share The crimp width 2 or the non-measurable crimp width can only be measured using a micrograph.
According the above-mentioned norms resistance is to gw measured between two points: I will review vw measurement techniques, discuss some trends in crimp quality, and address methods to improve efficiency in vw data collection.
Most terminal manufacturers do not reference tolerances for crimp width.
In these difficult times, wire harness manufacturers are looking to expand business in their existing markets vw are looking for new markets. When you have some manufacturing companies who want products made to the UL spec and vw who want products made to SAE specs, how do you keep track of the differences?
Finally, the new systems are far less expensive. If the measurement is not taken at the highest point vw the crimp, the measurement may be incorrect. SM Contact Engineering has done significant work to investigate the most common industrial crimp standards in terms of components requirements, dimensions, compression rate and contact resistance.
Exotic materials aluminum, steel, fiber, etc. Vwhopefully this gives you some advanced warning about what might be needed in the future.
The answer is IEC norm which gives vww test schedules and techniques. Pull test rates vary vw specifications as vw The VW and A specifications states that for crimp height measurements, a micrometer with a point and a blade Vw The solutions in the new systems have a Ph value equal to that of water 660330 they are much safer to use and no special procurement and waste processes are required.

Only the A specification makes crimp height measurement optional. Micrograph systems, or crimp cross sectioning equipment, were typically only seen where applicator tooling was manufactured or in the vw of the large wire harness suppliers.
Technically it between the tangents vw the radii of the crimp die.
Pull rate is the rate at which the wire and the are pulled apart. Site Map Legal notices. Tolerances are sometimes an issue as well. Since PCB can be destroyed and harder materials cannot 6033 compressed so much, it is necessary not to include such a component into compression measurement. Crimp Quality Standards Comparison and Trends.
Usually, higher pull test values can be achieved with higher pull rates. Keeping all of the specifications straight and understanding all of the differences is increasingly difficult.
Vw other specifications do not state requirements on tooling. The reason is to eliminate the possibility for vw flash to affect the measurement Fig. Not only do we need to keep track of the numerous standards in the Vw but now that US companies are bidding for European jobs, we need to understand the European standards as well.
On the other hand, this type of equipment is the only way to get a clear picture of the inside vw the crimp Fig 5. Aside from simple vw made during 6030 harness manufacturing process, terminals can go out of vd in the manufacturing process and frequently companies need to use terminals that are too large for the wire. USCAR specifies a rate between 50 — mm per minute, but mm per minute is preferred.
As for wire materials flexible copper is the only option. The following article will compare and contrast the wv quality vw that are most commonly used today.
There are only two cases when splice technology is considered: The air ve inside the crimp clearly indicate that the terminal is too big for the wire.
Burr height 8 and burr width 9 are indications vw crimp anvil wear. What do industrial crimp norms say about splice connection?
