11、nse from IHS -,-,- ISO 16132:2004(E) iv ISO 2004 All rights reserved 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 technic
12、al 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 wi
13、th the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Inte
14、rnational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document ma
15、y be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16132 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 2, Cast iron pipes, fittings and their joints. Copyright Internationa

17、ended purpose of a seal coat is to reduce the contact between a cement mortar lining and the contents of a water main, thereby restricting the leaching of inorganic materials into the water supply. Seal coats are usually specified where the pipeline is to convey soft waters and/or where residence ti
18、mes are very long. Supply water quality data for such pipelines should be discussed between the prospective client and the seal coated pipe supplier to ensure the suitability of the product for use. Attention is drawn to the fact that seal coated cement mortar lined surfaces in contact with, or like
19、ly to come into contact with, potable water need to conform to the requirements of national or international water supply or water quality regulations. Approval may be required for the individual components of the system or for the combined system depending upon the requirements of those national or
20、 international water supply or water quality regulations when used in accordance with the product manufacturers instructions for use; and under any other appropriate conditions defined for that product within any published list of substances, products and processes approved to those Water Supply or
21、Water Quality Regulations.

23、served 1 Ductile iron pipes and fittings Seal coats for cement mortar linings 1Scope This International Standard specifies the requirements for seal coatings for factory application to the surfaces of cement mortar linings, which are factory applied to the interior of ductile iron pipes and fittings
24、. It also gives performance test requirements for short term sealing efficiency and long term durability and requirements for routine testing for visual appearance, coating thickness and adhesion. This International Standard is applicable to products for potable and other water applications. 2Normat

32、ents 4.1Short term sealing efficiency When tested in accordance with Annex A, the pH of the test water shall not exceed 9,5. By agreement between the manufacturer of the product and the customer, other performance tests with other exposure periods, test waters and/or limits of pH value may be undert
33、aken to suit particular national or customer requirements. 4.2Long term efficiency When tested in accordance with Annex B, the pH of the test water shall not exceed 9,5 for each of the test samples. By agreement between the manufacturer of the product and the customer, other performance tests with o
34、ther exposure periods, test waters and/or limits of pH value may be undertaken to suit particular national or customer requirements. However, if the seal coat has been tested and documented by the manufacturer to a national standard and successfully used for a minimum of five years, the performance
35、of the type test in accordance with Annex B is only required for significant changes in the coating material, type or formulation which could adversely affect the performance of the seal coat. 5Routine Test Requirements 5.1General Coating and re-work procedures (e.g. drying regimes for solvent-based
36、 coatings and mixing and curing regimes for multi-component materials) shall be defined by the manufacturer of the product in agreement with the seal coat supplier, if necessary, so as to enable the product to conform to the requirements of this International Standard. The tests specified in 5.2 to
37、5.4 shall be carried out on factory seal coated pipes or fittings as opposed to separately prepared test pieces. Sampling plans for the tests specified in 5.2 to 5.4, specific to the seal coating material used, the size of the batch and the storage conditions, shall be specified by the manufacturer
38、of the product for each batch of product. Where a non-conforming product is identified, the product shall either be re-worked, so that it meets the requirements of this International Standard, or be rejected.

40、 irregularities likely to be detrimental to the performance of the seal coat (as required by the performance tests in this International Standard). The manufacturer shall define those coating irregularities (e.g., hairline cracks or pinholes) which are considered not to be detrimental to the perform
41、ance of the seal coat (as required by the performance tests in this International Standard), taking into account the nature of the seal coat material. 5.3Coating thickness When tested in accordance with Annex C or any appropriate method defined in ISO 2808, the wet or dry coating thickness shall be
42、within the limits specified by the manufacturer of the product in conjunction with the seal coat supplier, if necessary. 5.4Adhesion When tested in accordance with Annex D, one of the following requirements shall be met: where a cross cut is made in the seal coat, the adhesive strength shall fall wi
43、thin the range of 1 to 3; or where no cross cut is used, the area of disbonded coating shall be less than of the test area. Any area damaged during testing shall be repaired in accordance with a procedure defined by the manufacturer of the product in agreement with the seal coat supplier. 6Marking E
44、ach seal coated pipe or fitting shall be identified with the pipe manufacturers name or mark. In addition, seal coated pipes shall be indelibly and legibly marked on the external surface with the number and year of this International Standard.

47、of test water after three successive periods of exposure within a seal coated pipe sample. A.2Materials and apparatus A.2.1Paraffin wax, solventless epoxy, silicone resin or other suitable sealing material. A.2.2Test water, having bicarbonate alkalinity of approximately as CaCO3, at equilibrium with
48、 the atmosphere (i.e. no artificially induced carbon dioxide level), and with a stable pH of . This water shall be produced by dissolving of CaCl2 (calcium chloride) and of NaHCO3 (sodium bicarbonate) in of distilled water. A.2.3Petroleum jelly. A.3Apparatus A.3.1Glass plate. A.3.2pH meter, having capacity to measure pH 0 to pH 14, with discrimination of a pH of 0,01 or better. A.4Preparation of test samples The test shall be c
