IEEE C135.90 pdf download IEEE Standard for Pole Line Hardware for Overhead Line Construction
1.Overview
1.1 Scope
This standard covers the requirements of inch-based hardware commonly used in wood pole overhead lineconstruction. Metric hardware is not covered by this standard.
1.2 Purpose
This standard will combine several existing IEEE，ANSI, and NEMA standards that are either current orarchived.These standards provide the user and manufacturer with established manufacturing specifications.The current use of several standards requires work on each standard on a five-year cycle，which hasresulted in some of these standards being archive. The combined standard will prove for a timely reviewprocess for the standard and will provide the industry with a current standard for widely used pole linehardware.

3. Definitions for acceptability and sampling
acceptance quality limit(AQL): The maximum percent defective (maximum number of defects per100 units) that,for a sampling inspection, can be considered satisfactory as a process average.
average test value ( xn ):
Xn =(X+X+X+ …+X,y/nwhere
Xi,Xz,….Xnare individual test valuesn
is the total number of units tested
defect: Any nonconformance with specified requirements of the tested unit of product. For this standard, adefect is defined as a unit of product that, when iested,falls below its specified rated ultimate strength.
lot: A quantity of line fasteners sclected and agreed upon by the manufacturer and customer as beingrepresentative of a homogeneous population.Each lot, as far as is practicable, shall consist of units ofproduct of a single type,grade,class,size,and composition that are manufactured at essentially the sametime and under essentially the same conditions. Considcration should be given to limit the lot size, whereapplicable，to each heat-treating andor annealing process of a group of units. As necessary，themanufacturer shall provide adequate and suitable storage space for each lot and means for properidentification.Any lot shall not exceed 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 random selection without regard to unitquality.
sample size: The number of units of product based on the lot size.Minimum sample sizes are given inTable 1.
