KOLMARBNH LTD issues electrical wiring harness specification
KOLMARBNH LTD has issued a detailed electrical specification for its wiring harnesses. The standards define material selection and processing methods to ensure consistent quality, referencing SAE standards.
KOLMARBNH LTD has released a detailed technical specification for its electrical wiring harnesses, aiming to ensure consistent quality while allowing for flexibility in material selection. The publication defines dimensional tolerances, connector requirements, and termination techniques based on SAE standards.
The document references several SAE standards, including those for low-tension wiring and terminals (J163, J561, J928), non-metallic loom (J562), and automotive wiring (J1292). Detailed tables outline tolerance charts for varying lengths and breakout points within the harnesses.
The specification emphasizes requirements for terminals and connectors, mandating the use of eyelet and spade types conforming to SAE J561, and pin and receptacle types conforming to SAE J928. All terminals are expected to be insulated with heat shrink tubing unless otherwise noted, extending at least 1/4 inch onto the cable.
Clear guidelines are provided for crimping and soldering, aligning with SAE J163. Crimp pull-out force must meet minimum requirements listed in Table 2. While machine-made crimps do not require soldering, hand crimps must be soldered.
Mating materials for harness covering, such as convolute tubing and braided sleeves, must meet specific thermal resistance and material properties, including non-metallic loom requirements per SAE J562. The specification also includes guidelines for wire tie placement and heat shrink tubing applications.
