Independent Inspection relates to examination of a "lot" of material by an independent inspector employed by a commercial agency. Inspection means an examination of material in sufficient detail to insure conformity with all phases of the specification under which it was purchased. Inspection prior to treatment must be made after the products are manufactured and ready for treatment. If poles are trimmed to length, inspection prior to treatment may be done prior to framing, providing inspection hammer brands are not removed during framing. When framing is done after white inspection, the framing must be inspected after treatment. Producer is used to describe the party who manufactures and treats poles. Purchaser refers to either the REA borrower or to a contractor acting as the borrower's agent, except where a part of the specification specifically refers to only the borrower or the contractor. Quality control designee refers to an individual designated by the producer to be responsible for quality control. Reserve treated stock consists of timber products treated in accordance with this specification, prior to and in anticipation of the receipt of specific orders, and held in storage ready for immediate shipment. Supplier is a term used interchangeably with producer. Transmission poles - Unless otherwise indicated, any pole 50 feet or longer is designated as a transmission pole. Treating charge refers to all the material treated in a cylinder at one time. Treating plant is the organization that applies the preservative treatment to the poles. . .
