Page Count: 199
scope:

a. AECTP-230 complements, amplifies, and extends information previously contained in STANAG 2895 by identifying potential damaging effects that natural and induced environmental conditions have on materiel, and by providing guidance on the selection of suitable test methods.

b. AECTP-230 series of leaflets are organised around classes of materiel items. The leaflets focus on the effects of the natural environment, or on the act or process by which environments experienced by materiel items are altered by environmental factors inherent in circumstantial conditions, platforms, or other materiel items that surround them. These leaflets are not intended to be comprehensive. When used in conjunction with AECTPs 100 and 300 (and other sources of relevant information), these leaflets provide information on climatic conditions that should enable a comprehensive and cost effective set of environmental tests (type approval or qualification) to be selected, formulated, and conducted in response to project environmental and related requirements.

c. AECTP-230 does not address all environments arising from accident, hostile conditions or nuclear effects.

Purpose

a. The purpose of the AECTP-230 series of leaflets is to present characteristics and data samples of natural and induced climatic conditions that influence the design of materiel. For the purpose of this document, induced climatic conditions are the ambient environmental conditions resulting from the modification of the natural climatic conditions due to the structure in which, or on which, the materiel is utilised.

b. Leaflet 231 gives general guidance on the types and causes of natural and induced climatic environments, and gives information that is applicable to a variety of materiel types and platforms. Induced environments included are: 

- Temperature (including solar radiation)

- Humidity

- Air Pressure

- Hydrostatic Pressure

- Icing

- Dust and Sand

- Wetting

- Erosion by Impact

Section 231 should be consulted before any other leaflets in AECTP- 230 are consulted.

c. Sections 232 to 239 cover different situations in which materiel may be found, and follow a standardised format. For each situation, the characteristics of relevant induced environments are described for each set of circumstances that may apply. The potential damaging effects of those environments are described, and advice is given on the selection of test methods and severities.
