ASTM F1433-97(2010)

Standard Specification for Mechanically Refrigerated Shipboard Air Conditioner (Withdrawn 2019)

ABSTRACT
This specification covers self-contained mechanically refrigerated air conditioners for shipboard use in air circulation, air cooling, and dehumidification. These air conditioners are intended for use in compartments and areas where central system air conditioning is not provided. The air conditioners should be of the following types, and arrangements as specified: type I - drip-proof protected, and type II - explosion-proof enclosed; arrangement A - with air discharge plenum, and arrangement B - without air discharge plenum. The operation, air-circulating equipment, ship inclination, capacity, overload, and condensation of the air conditioner shall meet the requirements prescribed. The inspection requirements specified in this specification are classified as follows: first article inspection; quality conformance inspection; visual examination; first article test procedures; and operating test.
SCOPE
1.1 This specification covers self-contained mechanically refrigerated air conditioners for shipboard use in air circulation, air cooling, and dehumidification.
1.2 These air conditioners are intended for use in compartments and areas where central system air conditioning is not provided.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This specification covers self-contained mechanically refrigerated air conditioners for shipboard use in air circulation, air cooling, and dehumidification.
Formerly under the jurisdiction of Committee F25 on Ships and Marine Technology, this specification was withdrawn in July 2019 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
