Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

Introduction

Historically, different types of boom end connectors have been produced. This International Standard addresses the need to connect booms having dissimilar connectors during oil spill incidents where various operators may join forces to combat an oil spill or where normally incompatible boom stock must be used together.

The American Society for Testing and Materials (ASTM) Committee F-20 (Hazardous Substances and Oil Spill Response) has been preparing standards on related subjects for years. This organization has prepared two standards relating to boom connectors, namely ASTM F962-99 and ASTM F1657-96.

The first of these standards, ASTM F962, specifies standard mating requirements, or geometry, for boom connectors or adaptors. ASTM F962 was never widely accepted in the international community because many users believe that this mating geometry has inherent design limitations. In particular, the required strict tolerance between mating faces of the two joining connectors can result in connection problems. Some reported concerns or deficiencies with boom connector designs that use the ASTM F962 mating specifications are as follows:

• Slight bending along the length of the connector can easily occur during operation or, in particular, during roll-up or storage on the boom reel, resulting in the inability to join them together again;
• The design is more susceptible to experiencing difficulties joining connector ends if the connector face has been dented or marred through impact;
• Dirt and debris can be trapped on a mating surface, preventing proper fitting and connection, or requiring careful cleaning of the connectors;
• During cold weather operations, ice can form at the mating faces, making connection difficult or impossible; and
• The connection is not always secure. The use of a self-locking pin has occasionally resulted in excessive play in the connection and eventual release.

With respect to permanently incorporating a universal requirement or standard connector in all boom systems (instead of using an adaptor only when required), discussions with spill response operators and oil boom producers clearly indicate that, in many cases, this will not provide an appropriate or realistic standard practice. Booms and connectors are often designed or selected by an operator based on the needs that are suitable for their particular operating conditions. Also, producers choose connectors based on the needs of the particular boom design. In effect, many users think it is unlikely that any single standard connector mating criteria (as, for example, ASTM F962) will provide the characteristics to satisfy the specific requirements of all users.

The second of these standards, ASTM F1657, was subsequently developed to provide another approach to oil boom connectors. Instead of providing a standard connector design, it provides a common method for joining existing booms with different connector designs in the field during a major spill incident. This standard does not attempt to have all manufacturers and spill responders use universal connectors at all times. Instead, it specifies modifications on existing connectors in the way of incorporating holes at specified locations to allow for this standard connection method during major response incidents. Alternatively, boom manufacturers may provide an adaptor that would accomplish the same end result.

After considering these existing ASTM standards and discussions with individuals involved in the development of these standards, i.e. spill responders and boom producers, this International Standard was developed to use the same mating specifications as in ASTM F1657. However, this International Standard encourages the use of separate adaptors in most cases, to avoid the possible adverse effects of modifications to existing connector designs when incorporating these mating specifications. These mating specifications may be incorporated into existing connectors, if preferred and possible, only when the manufacturer or user can ensure that the modifications will not alter the strength and performance of the connector.

This International Standard contains the essence of ASTM F1657, with changes and additional details incorporated in certain Clauses.

1 Scope

This International Standard specifies a universal method for the joining of oil spill containment booms with dissimilar connectors through the use of a standard adaptor with prescribed mating specifications. This International Standard does not intend to replace the design of existing connectors.

This International 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 International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2 Terms and definitions

For the purposes of this International Standard, the following terms and definitions apply.
