BS MA 105-3-1987 (1999) ISO 8304-1984 PDF

Full title and description

STB BS MA 105-3-1987 (1999) — adoption of BS MA 105-3:1987 based on ISO 8304:1984. This national publication reproduces the British Standard MA 105-3 (1987) which implements the technical content of ISO 8304:1984, covering principal mating dimensions for the ventilation system of series‑3 shipborne barges.

Abstract

This standard specifies principal mating dimensions required for connecting the ventilation system of series‑3 shipborne barges to the ventilation arrangements of barge‑carriers (typically using flexible hoses and mating fittings). It defines the key interface dimensions so ventilation ducts and hoses are interchangeable and properly sealed between barge and carrier.

General information

• Status: National adoption (STB) of BS MA 105-3:1987 listed as an available document; the original ISO 8304:1984 is recorded as withdrawn in ISO’s lifecycle.
• Publication date: ISO 8304:1984 (December 1984); BS MA 105-3:1987 (31 July 1987); STB adoption/republication referenced with date 1999.
• Publisher: STB (national standards office / national publisher for the adopted text); original publishers: British Standards Institution (BS MA 105-3:1987) and International Organization for Standardization (ISO 8304:1984).
• ICS / categories: Shipbuilding / ship systems — ventilation; primary ICS classification for ISO 8304 is in the 47.060 / shipbuilding technical area (marine ventilation / HVAC).
• Edition / version: ISO 8304 — Edition 1 (1984); BS MA 105-3 — 1987 issue; STB shows a 1999 national reissue/adoption of the BS text.
• Number of pages: BS MA 105-3:1987 — 8 pages; ISO 8304:1984 — 2 pages (ISO’s published International Standard record).

Scope

The document covers the principal mating dimensions for the ventilation system fitted to series‑3 shipborne barges so that the barge ventilation can be jointed to the ventilation system of the barge‑carrier by means of flexible hoses and mating fittings. It is focused on the dimensional interfaces (flanges, spigots, clearances and mating arrangements) required to ensure mechanical compatibility and effective ventilation transfer during carriage and handling of ventilated cargoes.

Key topics and requirements

• Principal mating dimensions for ventilation ducts and fittings (flange/spigot geometry and nominal sizes).
• Dimensional tolerances and clearances to ensure interchangeability of flexible hoses and mating connectors between barge and carrier.
• Basic sealing/interface considerations to maintain ventilated cargo conditions during transport and transshipment.
• Applicability limited to series‑3 shipborne barges and associated barge‑carriers; not a comprehensive HVAC design standard.

Typical use and users

Primary users include shipbuilders, barge and barge‑carrier designers, marine ventilation equipment manufacturers, classification societies assessing compatibility, port and cargo handling engineers, and standards libraries procuring national adoptions of international/materiel interface standards.

FAQ

Q: What is this standard?

A: It is the national (STB) edition reproducing BS MA 105-3:1987 which implements the technical content of ISO 8304:1984; the text defines principal mating dimensions for barge ventilation interface components.

Q: What does it cover?

A: The standard covers dimensional interface requirements — flange/spigot sizes, mating arrangements and tolerances — to ensure that ventilation ducts and flexible hoses of series‑3 shipborne barges correctly mate with corresponding fittings on barge‑carriers. It does not provide full HVAC design or performance criteria.

Q: Who typically uses it?

A: Shipbuilders, barge‑carrier designers, ventilation hardware manufacturers, classification societies, port cargo engineers, and procurement/standards offices that need to ensure mechanical compatibility of ventilated cargo interfaces.

Q: Is it current or superseded?

A: The ISO record for ISO 8304:1984 shows that the International Standard is withdrawn in ISO’s lifecycle; the national adoption (STB) and the BS 1987 text remain historical/adopted documents for interface reference but users should check with their national standards body for current status and any newer replacements or related guidance.

Q: Is it part of a series?

A: Yes — it is specific to series‑3 shipborne barges and is one part of the broader body of shipbuilding and marine‑ventilation standards developed under ISO/TC 8 and related national standards programs.

Q: What are the key keywords?

A: shipborne barges; ventilation system; mating dimensions; flexible hose; flange; series 3; ISO 8304; BS MA 105-3; STB.
