MIL-STD-105 ¨C Sampling Procedures and Tables for

Inspection by Attributes

Subject/Scope:

This publication establishes lot or batch sampling plans and procedures for inspection

by attributes. This publication shall not be "interpreted to supersede or conflict with any

contractual requirements. The words "accept", "acceptance", "acceptable", etc, refer

only to the contractor's use of the sampling plans contained in this standard and do not

imply an agreement by the Government to accept any product. Determination of

acceptability by the Government shall be as described in contractual documents. The

sampling plans described in this standard are applicable to AQL's of .01 percent or

higher and are therefore not suitable for applications where quality levels in the

defective parts per million range can be realized.

Soft Conversion of Imperial to Metric

Conversions, when made, consider materials that are available in metric or imperial sizes rather than converting

sizes exactly. For example: Panelboard (plywood) in the US is typically 4 feet X 8 feet (1220 x 2440 mm) while

panelboard in metric countries is typically 1200 X 2400 mm. Since the standard was developed based on readily

available materials these variations in material sizes could not have been practically considered.

FOREWORD

This publication provides sampling procedures and reference tables for use in

planning and conducting inspection by attributes. The sampling concept is based

on the probabilistic recurrence of events when a series of lots or batches are

produced in a stable environment.

This publication should be used to guide the user in the development of an

inspection strategy that provides a cost effective approach to attaining

confidence in product conpliance with contractual technical requirements. The

user is warned of the assumed risks relative to the chosen sample size and

AQL.

Military specifications should not contain requirements for use of specific

sampling plans, nor should they provide AQL's or LTPD's as a requirement.

Sampling plans for continuous, rather than lot inspection, are contained in

MfL-STD-1235, "Single and Multi-Level Continuous Sampling Procedures and Tables

for Inspection by Attributes".
