ASTM F1433-97 (2010) PDF

Full title and description

Standard Specification for Mechanically Refrigerated Shipboard Air Conditioner — designation F1433−97 (reapproved 2010). The document specifies requirements for self‑contained mechanically refrigerated air conditioners intended for shipboard use (air circulation, cooling and dehumidification), including construction, refrigerant systems, materials, components, tests and inspection categories.

Abstract

This specification covers self‑contained, factory‑assembled mechanically refrigerated shipboard air conditioners designed for compartments where central systems are not provided. It defines types/arrangements, materials and construction details (compressors, condensers, evaporators, receivers, controls), performance and testing/inspection requirements, and references safety and industry standards for refrigerant systems and electrical components. The standard was reapproved in 2010 and later withdrawn.

• Publication date: Designation originally 1997; reapproved May 1, 2010 (F1433−97 (2010)).
• Publisher: ASTM International (American Society for Testing and Materials).
• ICS / categories: Marine ventilation, air‑conditioning and heating systems — ICS 47.020.90.

• Number of pages: 8 pages (historical record).

Scope

The standard applies to self‑contained mechanically refrigerated air conditioners for shipboard applications used for air circulation, sensible cooling and dehumidification in spaces without central air‑conditioning systems. It specifies construction and materials, refrigerant system requirements, electrical and safety references, performance definitions (net cooling and dehumidifying effects), classification of types/arrangements, and inspection and test methods required for certification and quality conformance. (Values stated in SI units.)

Key topics and requirements

• Classification of unit types and arrangements (e.g., drip‑proof, explosion‑protected; with or without air discharge plenum).
• Requirements for refrigerant systems and components (compressor types — hermetic/open; liquid receiver capacity; controls; charge and dehydration).
• Condenser design for seawater cooling (shell‑and‑tube construction, copper‑nickel tubes, means for purging air/noncondensables, cleanability, zinc anodes).
• Cooling coil/evaporator and condensate collection requirements (finned‑tube construction, drip pans and drains).
• Materials and manufacture constraints (forbidden materials, corrosion avoidance, specified alloys and fastenings).
• Inspection and testing: first article inspection, quality conformance, visual examination, first article tests and operating tests.
• Referenced safety and industry standards to be met (e.g., ASHRAE, ARI, UL requirements listed in the standard).

Typical use and users

Naval architects, shipbuilders, marine equipment manufacturers, shipboard HVAC designers, procurement/specification engineers, and maintenance/inspection personnel use this specification when selecting, supplying or qualifying self‑contained shipboard air conditioners for vessels and offshore platforms where local (unitary) air‑conditioning is required. It was used to ensure marine suitability (materials, seawater condenser design, anti‑corrosion measures) and defined test/inspection practices for contractual acceptance.

Related standards

The specification references and aligns with industry and safety standards such as ARI 210 (unitary equipment), ASHRAE 15 (safety code for mechanical refrigeration), ASHRAE 37 (testing/rating of unitary equipment), UL 465 (electrical), and multiple ASTM material specifications (for example B61, B75, B148, B209) as well as naval/marine procurement specifications; the ASTM record indicates the document was withdrawn without a direct replacement.

FAQ

Q: What is this standard?

A: ASTM F1433−97 (reapproved 2010) is a specification that defined requirements for self‑contained mechanically refrigerated shipboard air conditioners — covering design, materials, refrigerant systems, performance definitions and inspection/test criteria.

Q: What does it cover?

A: It covers self‑contained unitary air conditioners intended for shipboard compartments (cooling, circulation and dehumidification), including condenser/evaporator construction, compressor types, refrigerant system requirements, materials, cleaning/maintenance access, and inspection and testing procedures.

Q: Who typically uses it?

A: Marine equipment manufacturers, shipbuilders, naval architects, procurement/specifiers and maintenance/inspection teams involved in supplying or accepting shipboard HVAC units used the standard to ensure marine‑appropriate construction and performance.

Q: Is it current or superseded?

A: It is withdrawn. ASTM’s document record shows F1433−97 (reapproved 2010) was withdrawn in 2019 and no direct replacement is listed on the ASTM record. Users should not apply the withdrawn standard for new procurements without confirming a current normative reference; consult ASTM or relevant naval authorities for current guidance.

Q: Is it part of a series?

A: The standard is part of ASTM’s F‑series related to shipbuilding and marine equipment specifications (volume/committee listings for marine standards). It cross‑references several material and HVAC testing standards but was not migrated into a later F‑series replacement before withdrawal.

Q: What are the key keywords?

A: Shipboard air conditioner, mechanically refrigerated, seawater condenser, evaporator, compressor, liquid receiver, marine HVAC, dehumidification, ASTM F1433.
