- [1] extending in the lengthwise direction, as distinguished from transverse. [2] said of any fore-and-aft structural member, such as a frame or bulkhead.
- Running lengthwise.
- Along the length of a structure.
- Direction parallel to the long axis of an object and perpendicular to its radius — for example, down the length of a cylinder. compare circumferential; radial; transverse. lot tolerance percent defective (ltpd): the poorest quality, in percent defective, individual lot that is acceptable in a sampling plan. ltpd is the percent defective that will be accepted by the sampling plan at most 10 percent of the time. with such a plan, the producer agrees to supply just enough nonconforming product such the consumer will accept the lot using the agreed to sampling plan and acceptable quality level. compare acceptable quality level. lumen (lm): si photometric unit of luminous flux, weighted according to the photopic vision response. one lumen equals the light emitted by one candela (cd) point source into one steradian (sr) solid angle (1 lm = 1 cd/sr).
