Full title and description

ISO 14886:2014 — Ships and marine technology — Large yachts — Structural fire protection for FRP yachts. This international standard specifies an equivalency method to assess the structural fire protection performance of insulated fibre‑reinforced plastic (FRP) sandwich laminates used in large yachts (24 m and over) by comparing candidate laminates to a fire‑tested model laminate using heat‑transfer principles.

Abstract

ISO 14886:2014 defines requirements and a calculation‑based equivalency method (based on the Fourier Number) to demonstrate that an insulated FRP sandwich laminate offers fire resistance equivalent to a model mineral‑wool insulated sandwich laminate that has been fire‑tested and approved under the IMO FTP Code. The method takes into account thermal, mechanical and physical properties of the insulation and FRP laminate to determine equivalence for use in large yachts not subject to SOLAS.

Scope

Applies to the structural fire protection of large FRP yachts of 24 m in length and over carrying up to 12 passengers. The standard provides a method to demonstrate equivalency of proposed insulated FRP sandwich laminates to a model, fire‑tested insulated sandwich laminate (approved under the IMO FTP Code) using heat‑transfer analysis. ISO 14886:2014 is not applicable to vessels regulated by SOLAS. The standard excludes detailed treatment of attachments, penetrations and other openings (doors, windows, hatches) that could impair performance.

Key topics and requirements

• Equivalency method based on heat‑transfer (Fourier Number) to compare candidate and model laminates; equivalence requires Fo(candidate) ≤ Fo(model) and comparable skin/core thickness and density.
• Definition of the reference/model insulated FRP sandwich laminate (typically mineral‑wool insulated, fire‑tested under IMO FTP Code) used as the benchmark.
• Consideration of thermal, mechanical and physical properties of insulation and FRP skins in the equivalency assessment.
• Applicability limits (yacht length, passenger number) and explicit exclusion of SOLAS vessels and certain details (penetrations, openings).
• Guidance for demonstrating that an alternative insulated FRP construction performs as a fire‑resisting division when tested/assessed in accordance with the method.

Typical use and users

Used by yacht designers and naval architects, classification societies, shipyards and builders of large FRP yachts, material and insulation manufacturers, fire safety engineers, and regulatory assessors who need to demonstrate that alternative FRP sandwich constructions provide acceptable structural fire protection equivalent to a tested reference laminate.

Related standards

Directly referenced to fire test procedures and approvals under the IMO FTP Code; interacts with SOLAS provisions for vessels that fall under SOLAS regulations (ISO 14886:2014 is explicitly not applicable to SOLAS vessels). It is developed under ISO/TC 8 (Ships and marine technology) and related technical committees for small craft and marine safety. Users may also consult IMO fire test guidance and national/regional regulations affecting yacht fire safety.

FAQ

Q: What is this standard?

A: ISO 14886:2014 is an international standard that specifies an equivalency method for assessing structural fire protection of insulated FRP sandwich laminates used in large yachts (24 m and over).

Q: What does it cover?

A: It covers the method (using heat‑transfer analysis and the Fourier Number) to demonstrate that a proposed insulated FRP laminate is equivalent in fire performance to a fire‑tested model laminate approved under the IMO FTP Code. It sets applicability limits (yacht length and passenger number) and excludes SOLAS vessels and certain details such as penetrations and openings.

Q: Who typically uses it?

A: Yacht designers, naval architects, shipbuilders, classification societies, materials and insulation manufacturers, fire safety engineers and regulatory assessors involved in the design, construction and approval of large FRP yachts.

Q: Is it current or superseded?

A: ISO 14886 was published in December 2014 (Edition 1). Users should check the ISO catalogue or their national standards body for any confirmation, revisions or amendments beyond 2014. As published in 2014 it remains the referenced edition unless a newer revision has been issued.

Q: Is it part of a series?

A: ISO 14886:2014 is a standalone International Standard developed under ISO technical committee work on ships and marine technology (ISO/TC 8). It relates functionally to IMO fire test procedures (FTP Code) and other marine safety standards but is not a numbered multi‑part series.

Q: What are the key keywords?

A: FRP, large yachts, structural fire protection, insulated sandwich laminate, Fourier Number, equivalency, IMO FTP Code, fire resistance.
