IEEE C135.90-2014 pdf free.IEEE Standard for Pole Line Hardware for Overhead Line Construction.
IEEE C135.90 covers thc requirements of inch-bascd hardware commonly used in wood pole overhead line construction. Metric hardware is not covered by this standard.
This standard will combine several existing IEEE. ANSI. and NEMA standards that are either current or archived, These standards provide the user and manufacturer with established manufacturing specifications. The current use of several standards requires work on each standard on a live-year cycle, which has resulted in some of these standards being archive. The combined standard will prove for a timely review process for the standard and will provide the industry with a current standard for widely used pole line hardware.

defect: Any nonconformance with specified rcquircmcnts of thc tested unit of product. For this standard, a defect is defined as a unit of product that, when tested, falls below its specified rated ultimate strength.
lot: A quantity of line fasteners selected and agreed upon by the manufacturer and customer as being rcprcscntativc of a homogeneous population. Each lot, as far as is practicablc. shall consist of units of product of a single type. grade. class. size, and composition that are manufactured at essentially the same time and under essentially the same conditions. Consideration should be given to limit the lot size, where applicable, to each heat-treating andor annealing process of a group of units. As necessary, the manufacturer shall provide adequate and suitable storage space for each lot and means for proper idcntiticatiow Any lot shall not cxcccd 35 000 units.
major defect: A unit of product that, when tested, falls below 85% of its specified rated ultimate strength.
sample: One or more units of product drawn from a lot using randoni selection without regard to unit quality.
sample site: The number of units of product based on the lot sue. Minimum sample sizes arc given in Table 1.
All anchor rods shall bc made of hot-rolled steci produccd by the open-hearth. basic-oxygen. or cleciricfumacc process and shall be of a grade and quality to meet the requircmcnts of this standard.
4.1.1 Dimensions
All dimensions bcforc zinc coating shall be in accordance with Figure I.
4.2 Nuts for anchor rods
All anchor rods shall be tlirnished with one square nut per rod unless otherwise specified. The nuts shall be assembled on the rods; suitable means shall be provided for preventing loss in transit. The nuts shall be of the heavy-duty square type and shall meet the requirements oIANSIASME Dimensions for nuts. before zinc coating, shall be in accordance with Table 2.
The maximum width across fiats applies at all points. No transverse section through the nut between 25% and 75% of the nut thickness, as measured from the bearing face, shall be less than the minimum width across flats.
The tops of nuts shall be flat and chamfered or washer crowned. The diameter of the chamfer circle shall be
equal to the maximum width across fiats within a tolerance of—15%.
The bearing surface shall be at right angles to the axis of the threaded hole within a tolerance of 30.
The axis of the tapped hole shall he concentric with the axis of the nut body within a tolerance equal to 5% (10% full indicator reading (FIR)) of the maximum width across the flats.IEEE C135.90 pdf download.
