SUBJECT 2436 OUTLINE OF INVESTIGATION FOR SPILL CONTAINMENT FOR STATIONARY LEAD ACID BATTERY SYSTEMS Issue Number 1
1.1 This test method covers the determination of flexural properties of unreinforced and reinforced plastics, including high-modulus composites and electrical insulating materials in the form of rectangular bars molded directly or cut from sheets, plates, or molded shapes. These test methods are generally applicable to rigid and semirigid materials. However, flexural strength cannot be determined for those materials that do not break or that do not fail in the outer fibers. This test method utilizes a four point loading system applied to a simply supported beam. 1.2 This test method describes two procedures (Procedure A and Procedure B), the selection of which depends on the behavior of the sample to be tested as explained below: 1.2.1 Procedure A, designed principally for materials that break at comparatively small deflections. It shall be used for measurement of flexural properties, particularly flexural modulus, unless the material specification states otherwise. 1.2.2 Procedure B, designed particularly for those materials that undergo large deflections during testing. It is suitable for measurement of flexural strength. 1.3 Comparative tests are permitted to be run according to either procedure, provided that the procedure is found satisfactory for the material being tested. 1.4 The values stated in SI units are to be regarded as the standard. The values provided in parentheses are for information only. 1.5 This 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 standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: This test method is similar to ISO 14125, Method B. However, ISO 14125, Method B specifies only a load span of 1/3 the support span whereas D6272 also permits a load span of 1/2 the support span. For this reason and other differences in tec
This part of ISO 13628 defines the technical requirements for safe, dimensionally and functionally interchangeable flexible pipes that are designed and manufactured to uniform standards and criteria. Minimum requirements are specified for the design, material selection, manufacture, testing, marking and packaging of flexible pipes, with reference to existing codes and standards where applicable. See ISO 13628-11 for guidelines on the use of flexible pipes and ancillary components.This part of ISO 13628 applies to unbonded flexible pipe assemblies, consisting of segments of flexible pipe body with end fittings attached to both ends. This part of ISO 13628 do
La présente partie de l'ISO 13628 définit les exigences techniques applicables à des canalisations flexibles, s?res, interchangeables du point de vue dimensionnel et fonctionnel, qui sont con?ues et fabriquées selon des normes et des critères uniformes. Elle spécifie des exigences minimales relatives à la conception, au choix des matériaux, à la fabrication, aux essais, au marquage et au conditionnement des canalisations flexibles, en faisant référence, le cas échéant, à des codes et normes existants. Par ailleurs, l'ISO 13628-11 fournit les lignes directrices relatives à l'utilisation des canalisations flexibles et éléments auxiliaires.La présente partie de l'ISO13628 s'applique aux assemblages de canalisations flexibles non collées constitués de tron?ons de corps de canalisations flexibles munis d'embouts fixés aux deux extrémités. La présente partie de l'ISO 13628 ne concerne pas les canalisations flexibles à structure composite. Elle ne s'applique pas non plus aux éléments auxiliaires de canalisations flexibles. L'Annexe B donne des recommandations pour les et les réducteurs de courbure.
This part of the standard specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of Sheet Moulding Compound (SMC) and Bulk Moulding Compound (BMC). Requirements for handling test material and for conditioning both of the test material before moulding and of the specimens before testing are found here.
This standard defines terms used in the plastics industry, including terms and definitions appearing in plastics standards (of ISO/TC 61), and general terms and definitions of polymer science used in all aspects of plastics technology.
This Standard contains unbonded flexible pipe systems for subsea and marine applications.
This International Standard specifies the minimum requirements for surface preparation, materials, application, inspection and testing of internal coating lining systems that are intended to be applied on internal surfaces of steel storage tanks of crude oil, hydrocarbons and water for corrosion protection. It covers both new construction and maintenance works of tank internal coating and lining as well as the repair of defective and deteriorated system. This International Standard also provides the minimum requirements for shop performance testing of the coated/lined samples and the criteria for their approval.
This International Standard provides guidelines and requirements for material selection of both seamless casing and tubing, and downhole equipment for CO2 gas injection and gas production wells with high pressure and high CO2 content environments [higher than 10 % (molar) of CO2 and 1 MPa CO2 partial pressure]. Oil production wells are not covered in this International Standard. This International Standard only considers materials compatibility with the environment. Guidance is given for the following: - corrosion evaluation; - materials selection; - corrosion control. This International Standard is aimed at high CO2 content wells, where the threat of low pH and CO2 corrosion is greatest. However, many aspects are equally applicable to environments containing lower CO2 concentrations. Materials selection is influenced by many factors and synergies and should be performed by either materials or corrosion engineer.
This European Standard defines the general requirements applicable to the specification of all types of glass mat reinforced polypropylene composite sheet (GMT) falling within the scope of this specification as defined in Part 1 of the standard including the sampling procedures, packaging, storage and labelling requirements.\nThis European Standard describes the procedures to be followed in the preparation moulded plaques from which are cut the test specimens for the determination of mechanical properties as specified in Parts 1 & 3.\nThis European Standard also defines the test methods to be used to determine the designated and specified properties given in Parts 1 & 3 respectively.
This European Standard is a specification for thermoplastic compression mouldable sheet consisting of textile glass mat reinforced polypropylene or equivalent products, as described in Part 1 of this specification.\nThe parameters to be defined in any GMT specification are defined in 4.1. Parameters to be specified are those, which should typically appear on data sheets. Only a selection of these parameters should be included on the certificate of conformity. The other parameters which are included in a specification should either be nominated by the manufacturer, or agreed between manufacturer and customer. These parameters are defined in 4.2.\nA selection of the specified parameters should be used for quality control purposes to check the conformity. The specification defines which parameters should be used for checking the conformity of the material. These parameters are defined as part of 4.1. Other specified parameters may be included if critical for a particular application or processing method. This is to be agreed between manufacturer and customer of a production lot and will be reported in the certificate of conformity, which should be in accordance with EN 10204.
