Detail of GB/T 16563-2017

Introduction of GB/T 16563-2017

This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 16563-1996 Series 1: Tank containers for liquids, gases and pressurized dry bulk — -Specification and testing. Compared with GB/T 16563-1996 Series 1: Tank containers for liquids, gases and pressurized dry bulk — Specification and testing, the main technical changes of this standard are as follows: — modification of the standard name which is changed to "Series 1 freight containers — Specification and testing — Tank containers for liquids, gases and pressurized dry bulk"; — addition of the definitions of the test platform, damping ratio, single degree of freedom system (SDOF system), shock response spectrum (SRS) and octave; — modification of the 6.6 Test No.5 — Internal restraint (longitudinal); — revision of Figure A.8 in Annex A; — addition of Annex D "Dynamic longitudinal impact test"; — modification of the original Annex D which is changed into “Bibliography”. This standard is identical to ISO 1496-3:1995 Series I freight containers Specification and testing — Part 3: Tank containers for liquids, gases and pressurized dry bulk AMENDMENT 1: Testing of the external restraint (longitudinal) dynamic. The Chinese documents consistent and corresponding with the normative international documents in this standard are as follows: — GB/T 1413-2008 Series 1 freight containers — Classification, dimensions and ratings (ISO 668: 1995, IDT); — GB/T 1835-2006 Series 1 freight container — Corner fittings (ISO 1161: 1984, MOD); — GB/T 1836-1997 Freight containers — Coding, identification and marking (ISO 6346: 1995, IDT); — GB/T 1992-2006 Freight container vocabulary (ISO 830: 1999, MOD); Series 1 freight containers — Specification and testing — Tank containers for liquids, gases and pressurized dry bulk 1 Scope 1.1 This standard specifies the technical requirements and test methods for tank containers suitable for the carriage of gases, liquids and solid substances (dry bulk) which may be loaded or unloaded as liquids by gravity or pressure discharge, for international exchange and for conveyance by road, rail and sea, including interchange between these forms of transport. 1.2 Except where otherwise stated, the requirements of this standard are minimum requirements. Tank containers to be used for the carriage of dangerous goods shall also meet the international and national requirements developed by the relevant competent authorities. 1.3 This standard is applicable to various types of containers listed in Table 1. Table 1 Container types Type of cargo and ISO type code designation a Minimum test pressure b bar gauge c Code basis Liquids Gases Dry bulk UN MM IMO/IMDG tank type Non-dangerous Dangerous Horizontal discharge Tipping discharge 2 1 5 70 d 0.45 71 73 85 87 1.5 + + 72 74 86 88 2.65 + + + 75 4 + + 76 6 + + 77 10 (10.5) + + (+) 78 22 79 Open Note: For all containers, other than ID and IDX, it is essential that the design requirements shall be in accordance of provisions in 5 1 5. a The IS0 type code designation does not imply the approval of any competent authority for the transport of specific goods or products the tank container may carry. The type code depends only on the test pressure (see 6.13). b The test pressure given is the minimum value of the respective class. Any tank container with a test pressure in the range between a given minimum pressure and the next higher minimum pressure belongs to the lower class. c Test pressure is expressed in bars since relevant intergovernmental codes, often implemented by national legislation, retain this unit of pressure. 1 bar = 100 kPa. d The number 70 may, in addition, be used to designate tank containers for which the type code relevant to the test pressure is not used. 1.4 The marking requirements for these containers shall be in accordance with the principles embodied in IS0 6346. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 668:1988 Series 1 freight containers — Classification, dimensions and ratings ISO 830:1981 Freight containers — Terminology IS0 1161:I984 Series 1 freight containers — Corner fittings — Specification ISO 6346:1984 Freight containers — Coding, identification and marking ISO 6487 Road vehicles — Measurement techniques in impact tests — Instrumentation 3 Terms and Definitions For the purposes of this document, the following terms and definitions given in ISO 830 apply. 3.1 tank container freight container which includes two basic elements, the tank or tanks and the framework and complies with the requirements of this standard 3.2 framework tank mountings, end structure and all load-bearing elements not present for the purposes of containing cargo, which transmit static and dynamic forces arising out of the lifting, handling, securement and transporting of the tank container as a whole 3.3 tank(s) vessel(s) and associated piping and fittings which are designed to contain the cargo carried Note: Baffles, surge plates or other perforated plates do not form tank compartments within the meaning of this definition 3.4 compartment a section of the tank formed by the shell, ends or complete bulkheads 3.5 gas fluid substance having a vapour pressure greater than an absolute pressure of 300 kPa at 50°C or as otherwise defined by the competent authority Note: 300 kPa = 3 bar 3.6 liquid fluid substance having a vapour pressure not greater than an absolute pressure of 300 kPa at 50°C 3.7 dry bulk assemblies of separate solid particles normally substantially in contact with one another which are, or may be rendered, capable of fluid flow 3.8 dangerous goods those substances classified as dangerous by the United Nations committee of experts on the transport of dangerous goods or by the competent authority as defined in 3.9 3.9 competent authority authority or authorities designated as such in each country or in each specific case by the governments concerned for the approval of tank containers 3.10 maximum allowable working pressure pressure assigned for operation by either a competent authority or other responsible person to a particular tank, above which that tank is not intended to be operated 3.11 test pressure gauge pressure at which the tank is tested (see 6.13.2) 3.12 total capacity volume of water which will completely fill the tank at 20°C 3.13 ullage portion of the total capacity of the tank not occupied by its cargo, expressed as a percentage of the total capacity 3.14 test platform fixed or mobile device that supports the tank container being tested and receives a direct impact 3.15 damping ratio ratio of actual damping factor to critical damping factor 3.16 single degree of freedom system; SDOF system system that may be fully defined with only one coordinate at any given moment 3.17 shock response spectrum; SRS curve based on the maximum response amplitude of a single degree of freedom system during the response as a function corresponding to the system’s intrinsic frequency, for a given impact 3.18 minimum shock response spectrum; minimum SRS reference curve (see Figure D.1) represents the minimum shock response spectrum for a valid test 3.19 octave frequency band with a frequency interval whose ratio of the upper limit frequency to the lower limit frequency is 2. 4 Dimensions and ratings 4.1 External dimensions The overall external dimensions and tolerances of tank containers covered by this standard shall be those established in IS0 668, except that tank containers may be of reduced height, in which case they shall be designated 1AX, 1BX, 1CX and 1DX. No part of the tank container, its associated fittings and/or equipment shall project beyond these specified overall external dimensions 4.2 Ratings The values of the rating, R, the maximum gross mass of the container, shall be those specified in IS0 668. However, taking account of the high density of many fluid cargoes, the values of the rating R chosen for the design and testing of 1BBB, 1BB, 1B, 1CC and 1C tank containers may be higher than those specified in IS0 668. For all containers in operation, such values shall in no case exceed the rating allowed for IAAA, 1AA and IA containers in IS0 668. 5 Design requirements 5.1 General All tank containers shall be capable of fulfilling the following requirements for the framework, the design and optional features of the tank and any optional provisions. 5.1.1 The ability of the tank container to withstand the specified design loadings shall be established by calculation or test. 5.1.2 The strength requirements for tank containers are given in diagrammatic form in Annex A (Normative) (these requirements are applicable to all tank containers as complete units except where otherwise stated). 5.1.3 The strength requirements for corner fittings (see 5.2) are specified in IS0 1161. 5.1.4 The tank container shall be capable of withstanding the test loads and loadings specified in Clause 6. 5.1.5 Each tank container shall be designed to withstand the effects of inertia of the tank contents resulting from transport motions. For design purposes, these effects may be taken to be equivalent to loadings of 2Rg longitudinally, Rg laterally and 2Rg vertically*. These loadings may be considered individually to be evenly distributed and to act through the geometric centre of the tank. Vertical loadings are total loadings including dynamic effects. It should be noted that the above loadings do not give rise to an increase in pressure in the vapour space. For design purposes, an equivalent pressure loading may be used. *Note: See 6.1 .I, Note 6. 5.1.6 Each tank container shall be capable of withstanding the requirements of 5.1.5 and the static head produced in the tank container while loaded to its rating R. Due regard shall be given to the liquid/dry bulk of highest density that is to be carried and to any compartmentation of the tank. 5.1.7 As the effects of loads encountered under any dynamic operating condition should only approach, but not exceed, the effects of the corresponding test loads, it is implicit that the capabilities of tank containers indicated in Annex A and demonstrated by the tests described in Clause 6 shall not be exceeded in any mode of operation. 5.1.8 Any closure in a tank container, which if unsecured could lead to a dangerous situation, shall be provided with an adequate securing system having, so far as may be practicable, external indication of the positive securement of that closure in the appropriate operating position. 5.1.9 Fork-lift pockets shall not be provided in tank containers. Note: Fork-lift transport of tank containers is considered dangerous because of stability problems with loaded or partly-loaded tanks and the danger of impact damage from the forks of fork-lift trucks. 5.1.10 The tank container materials shall be suitable for, or adequately protected from, the cargo and the environment in which the tank container may be operated. Due regard should be given to the problems of variation in ambient temperature, corrosive atmospheres, the possibility of uncontrolled cargo release in fire, etc. 5.1.11 The design of tank containers of types 1AAA and IBBB shall take into special account the problems of the dynamic instability of these containers, and their design requirements shall be consistent with those of types 1AA and 1BB tank containers when operating in the road/rail environment in a partially laden condition.
