(2) Exactly right. Paragraph 220.127.116.11.1 is meant to be used at the earliest
Before we continue examining these documents, let's examine a little
more closely the subject of contractor requirements.
In addition to the
specific data presented in a contract, there are usually references made to
When you deal with human factors engineering research,
development, and implementation, these references will include a series of
data item descriptions (DIDS).
Turn in your supplement to Page 108.
Starting on this page you'll find DID DI-H-7051.
The following pages
contain DI-H-7052 through DI-H-7059. These descriptions detail requirements
as broad as an overall Human Engineering Program Plan (DI-H-7051), as
general as a Human Engineering Progress Report (DI-H-7059), or as special as
DI-H-7058 (HE Test Report). You'll need to be familiar with these DIDS as
you begin to work with government contractors.
Your next document is MIL-STD-1474, 'Noise Limits for Army Materiel.'
If you look at the foreword, you'll see the definitions of three types of
hearing damage-risk criteria (DRC), hearing conservation
criteria, and materiel design standards.
As you thumb through this
standard, you'll see that it is similar in format to several you've already
It contains references, definitions, general requirements, and
Since noise was the subject of an entire lesson,
little else needs to be said at this point. Just be sure you're familiar
with the data available in MIL-STD-1474.
The final military document we need to examine in this lesson is HEL
Technical Memorandum 29-76, 'Guide for Obtaining and Analyzing Human
Performance Data in a Materiel Development Project.' Take a moment and read
the background provided on page 5 and the first paragraph of page 6. As you
can see, the value of human factors engineering is well recognized by the
Army. It should be obvious to you that the thrust of this report concerns
the use of Data Item 1334A (now renamed DI-H-7058).
This DID (Data Item
Description) is presented in its entirety. How does this document fit with
those we've already discussed?
(1) It provides you with the background to assure that all previous
specifications and standards have been applied properly. Turn to Page 54.
(2) It gives examples of how to test to see that HFE principles have been
applied. Turn to Page 75.
(3) Both of these are correct. Turn to Page 94.
