4.1 Comparison of brake horsepower developed and of specific fuel consumption rates from engine to engine may be made by use of data based upon a standard for composition of an engine assembly.4.2 The purchaser of the engine assembly will be fully advised of the minimum scope of assembly which the purchaser may rightfully expect to be encompassed by a response to a request for quotation and to be delivered in response to a purchase order unless the engine builder in the proposal or in the offer to sell has clearly advised otherwise.4.3 It will be made apparent to the purchaser that additional auxiliary and accessory equipment will be needed to supplement the defined engine assembly when full consideration is given to the application of the engine assembly as a prime mover in a specific vessel.1.1 This guide covers performance and minimum scope of assembly of all medium speed marine diesel engines intended for main propulsion of single or multiple screw propelled marine vessels or for vessels using other than screw propeller-type main propulsion.1.2 This guide is intended to supplement the regulations of legally constituted regulating authorities. In the event of any conflict, which may become apparent after publication of this guide, with such legally constituted regulations, the latter shall take precedence, as may be applicable within the jurisdiction of such authorities and specific to each case, unless such latter regulations are formally waived by proper cognizant authority.1.3 This guide is not intended to relieve the purchaser of the obligation fully to advise the engine builder of all of the purchaser’s unique operational considerations to allow those considerations to be satisfied.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The determination of dimensional change of pile yarn floor covering is useful in quality and cost control during manufacture of pile yarn floor covering. The appearance and performance may be affected by the changes in the dimensions of pile yarn floor covering. This test method is considered satisfactory for acceptance testing of commercial shipment because current estimates of between laboratory precision are acceptable, and this method is commonly used in the trade for acceptance testing.5.2 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them using competent statistical assistance. As a minimum use the samples for such comparative tests that are as homogenous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If a bias is found either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.1.1 This test method covers the determination of dimensional changes in the lengthwise and width-wise direction and distortion likely to occur when pile floor coverings are exposed to various conditions of moisture and heat. This method is applicable to all pile floor coverings including carpet module form.1.2 This method is applicable to machine made pile yarn floor covering.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversion to SI units that are provided for information only and are not considered standard.1.4 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.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method provides a procedure for identification of those finished textile floor covering materials that can be rated as flame-resistant under specific controlled laboratory conditions.5.2 This test method does not specify the use of an underlay material. If an underlay material is used to assess the effect of a specific underlay in combination with a specific floor covering, such a variation in procedure must be noted in the report.5.3 In this test, results are observed with the specimens in a horizontal plane. Different results are possible if the same material is tested or used in any other plane.5.4 Test Method D2859 for testing finished textile floor covering materials for flammability is considered satisfactory for acceptance testing of commercial shipments since the method has been used extensively in the trade for acceptance testing. In cases of disagreement arising from differences in values reported by the purchaser and the seller when using this method for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller shall be determined with each comparison being based on testing specimens randomly drawn from one sample of material of the type being evaluated.5.5 The test procedures of this standard are similar but not identical to those contained in the standards for the surface flammability of carpets and rugs of the U.S. Consumer Product Safety Commission4 (see also 1.1). The acceptance criterion of these CPSC standards requires that at least seven out of eight individual specimens of a given carpet or rug have passed the test, that is, that the charred portion of a tested specimen shall not extend to within 25.4 mm (1.0 in.) of the edge of the hole in the flattening frame at any point.5.6 The acceptance criterion of this test method is consistent with that of CPSC standards (see Section 10).1.1 This fire-test-response standard describes a test method for the determination of the flammability of finished textile floor covering materials when exposed to an ignition source under controlled laboratory conditions.1.1.1 Carpets and rugs offered for sale in the United States are required by the Consumer Product Safety Commission (CPSC) to comply with the test methods in 16 CFR 1630 or 16 CFR 1631, as appropriate.1.1.2 This test method is similar but not identical to the test methods contained in 16 CFR 1630 and CFR 1631 and issued by CPSC. If compliance with one of the CPSC test methods is required, this test method does not ensure regulatory compliance.1.2 This test method is applicable to all types of textile floor coverings, regardless of the method of fabrication or whether they are made from natural or man-made fibers. It is possible to apply this test method to unfinished material; however, the results of such a test shall not be considered a satisfactory evaluation of a textile floor covering material for ultimate consumer use.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.5 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests1.6 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.7 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.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This test method is used to determine the wet covering and volume change upon drying of thermal insulating cement.1.1 Wet covering capacity and volume change upon drying are often of major importance in the application of thermal insulating cement. These properties can be easily determined at the same time that the determinations of dry covering capacity are made. Therefore, the procedures for determining these three properties are covered together in this test method.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 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.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus.5.2 Quantitative heat release measurements provide information that can be used to compare wall or ceiling coverings and constructions and for input to fire models.5.3 Heat release measurements provide useful information for product development by giving a quantitative measure of specific changes in fire performance caused by component and composite modifications.5.4 Heat release data obtained by this test method will be inappropriate if the product will not spread flame over its surface under the fire exposure conditions of interest.5.5 Variations in substrates, mounting methods, and adhesives used to laminate composite products will potentially affect the test responses. These variables must be controlled during any comparative experiments.5.6 Test Limitations—The test data are invalid if any of the following occur:5.6.1 Explosive spalling,5.6.2 The specimen swells sufficiently prior to ignition to touch the spark plug or swells up to the plane of the heater base during combustion, or5.6.3 The surface laminate rolls or curls when placed under the radiant heater.5.7 The specimens are subjected to one or more specific sets of laboratory conditions in this procedure. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. The results are therefore valid only for the fire test exposure conditions described in this procedure.1.1 This fire-test-response test method covers determination of the ignitability and heat release rate of composites consisting of a wall covering or ceiling covering, a substrate, and all laminating adhesives, coatings, and finishes. Heat release information cannot be used alone to evaluate the flammability of wall coverings or ceiling coverings. The data are intended to be used for modeling or with other data to evaluate a material.1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. Heat release data at different heat fluxes are also obtained by this test method. The specimen is oriented horizontally, and a spark ignition source is used.1.3 The fire-test-response characteristics are determined using the apparatus and procedures described in Test Method E1354.1.4 The tests are conducted on bench-scale specimens combining the components used in the actual installation.1.5 The values stated in SI units are to be regarded as the standard. See IEEE/ASTM SI-10.1.6 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be used in conducting these tests. This test method potentially involves hazardous materials, operations, and equipment.1.7 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. Specific information about hazard is given in Section 6.1.9 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.1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
