The work of preparing International Standards is normally carried out through ISO t
10、echnical 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 clos
11、ely 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 n
12、eeded 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 (see www.iso.org/directives).

17、 17325-2:2014(E)IntroductionOil booms can be classified in two major types: Fence booms typically provide a stiffened barrier designed to float vertically in the water. Curtain booms are provided with flexible material for the underwater portion of the membrane (called the skirt).There are other typ
18、es of booms, such as special purpose booms and sorbent booms, which are not the subject of this part of ISO 17325.This International Standard gives some general guidelines for manufacturers as well as users with regard to subjects associated with producing, purchasing, and using such types of equipm
19、ent. It does not define any specific type and size of boom for a particular application, as many variables have to be taken into consideration. This part of ISO 17325 specifies the strength and performance requirements of booms and relevant test methods.This International Standard has been developed
20、 after considering the below standards and national legislative requirements.The American Society for Testing and Materials (ASTM) Committee F-20 has prepared two standards relating to boom connectors. ASTM F1093-99 specifies static laboratory tests of the strength of an oil spill response boom unde
21、r tensile loading. ASTM F1523-94 provides a guide on the selection of a containment boom that can be used to control spills of oil and other substances that float on the water.The Japanese Industrial Standard JIS F 9900-1 and JIS F 9900-2 provide the necessary conditions and specifications for the d
22、esign, manufacture, etc. of oil booms.This part of ISO 17325 incorporates and acknowledges use and refers to many elements provided in ASTM F1093-99, ASTM F1523-94, JIS F 9900-1, and JIS F 9900-2. However, it also contains changes and additional details on strength and performance requirements for o
23、il booms.

24、equirements of oil booms and associated test methods. It does not purport to address the safety concerns, if any, associated with their use. It is the responsibility of the user of this International Standard to establish the appropriate safety and health practices and determine applicability of reg

The main materials that constitute the body of
30、booms shall be oil-resistant and water-resistant, and shall not be susceptible to deterioration during long term storage under normal conditions. Booms shall have sufficient structural strength to withstand normal applications including towing, deployment and withdrawals. Booms to be mounted on boar
31、d oil tankers and used in explosive atmospheres shall be protected so as not produce a spark if they come in contact with the hull or other metal components. Booms shall be easy to store and shall not injure operators when deploying, unfolding, or withdrawing. Connection parts shall not have an effe
32、ct on the floating stability of booms, and shall be safe in use. Connection parts shall suit the breaking strength of the entire boom under any condition. See ISO 17325-31).5 Material performance and testThe boom manufacturer shall prove that all materials for bodies, components, connection parts, a
33、nd especially tension members, are suitable. This shall be provided by manufacturer test certificates. However, because the breaking strength of the boom assembly depends on proper production, the complete boom shall undergo a breaking strength test as stated in 5.3.4.The following provides informat
34、ion to determine the suitability of components. All the test results shall be recorded in the manufacturers certificates.5.1 Strength verificationThe manufacturer shall provide calculations of oil boom strength and dimensions taking into consideration the forces expected at the intended application.
35、 See ISO 17325-1:2014, Clause 8. Major components to be taken into consideration include but are not limited to the following. tension members, such as chains, ropes, and belts; boom wall material; floatation material; and end connectors.NOTE See ISO 17325-31).5.2 Tests (component)Testing of oil boo
36、m components is to be conducted and certified by manufacturers as follows.5.2.1 Oil resistanceTest results shall be proven by manufacturers certificates and in accordance with ISO 175.5.2.2 Weathering resistanceTest results shall be proven by manufacturers certificates and in accordance with ISO 301

38、omplete assembled boom by a recognized body.5.3.1 Visual inspectionBodies and connection parts of the booms shall be visually checked and shall not have any defects.5.3.2 Buoyancy testBoth freeboard and draught of booms floating in fresh water or salt water are to be measured at three arbitrary poin
39、ts near the centre part of booms. These data are to be recorded for classification according to ISO 17325-1:2014, Table 1.5.3.3 Air chamber leakage test (inflatable type only)Air chamber shall be expanded to maximum working pressure and left in that condition for one hour. Afterwards, the loss of th
40、e internal pressure shall be less than 10 % of the maximum working pressure.5.3.4 Breaking strength testIn order to verify the functionality of the entire boom assembly, a breaking strength test shall be carried out on one full-scale test specimen taken from ongoing production. It shall include all
41、accessories such as end connectors and towing gear. This test shall be carried out afloat in the operational position of the boom.The final product shall be identical to that which was tested.The breaking strength test shall be carried out under the following test requirements.5.3.4.1 Test facilityT
42、he test facility shall provide sufficient clearance for the (full-scale) boom specimen, one tensioning device, and testing equipment as shown in Figure 1, where the boom is launched in a straight position, floating in the absence of current and waves. It is exposed to longitudinal tension until brea
43、king or structural failure. A suitable tension-meter is needed to measure and record the load on the boom specimen.

44、rrangement5.3.4.2 Test specimenThe test is to be carried out on one complete section of the boom specimen. It shall include a towing gear at each end, connected by the type of end connector supplied or recommended by the manufacturer, as well as all accessories needed for operation of the boom.Only
45、if the size of one section exceeds the size of the test facility, the length of the boom may be reduced, but using complete full-scale segments only. This shall be recorded in the test report.5.3.4.3 Test proceduresThe specimen is attached between the end-support of the test facility and the tension
46、 meter with the individual towing devices attached to each end connector.A load shall be placed on the boom and tension increased in a linear manner. It shall be noted when failure is indicated. The test is to be continued until complete structural failure occurs.5.3.4.4 Multiple testsIf a manufactu
47、rer wants to test several test specimens, which are identical in design and way of production, but only different in size, the number of individual tests may be carried out only on one-third of all test specimen, but not less than three. The particular sizes to be tested shall be randomly selected b
48、y the test institute.In case one of the multiple tests fails, then individual tests shall be conducted for all other test specimen.5.3.4.5 RecordsPrior to the test, the boom test specimen has to be specified by design drawings, parts lists, quality certificates of components (e.g. belts, ropes, chai
49、ns) suppliers, and classification according to ISO 17325-1. Data including a description of the test rig and the force at which partial and complete failure occurred shall be reported.5.3.4.6 ValidityThe certificate issued on basis of this test shall not be limited in time. But it becomes automatically invalid if any structural member (e.g. wall material, tension members) or applied production methods are changed.4 ISO 2014 All rights reservedBS ISO 17325-2:2014ISO 17325-2:2014(E)Bibliography
