5.1 Test Method F88 has been the standard for the mechanical peel strength testing of peelable seals since the 1960s. Normally the testing is run on a portion of the seal. The result is an actual seal strength picture of that portion of the seal. This test method is different in that the entire package seal is peeled open and data collected for the entire sealed area.5.2  This test method is a tool for quality assurance use as well as performance evaluation of a seal during separation.5.3  With appropriate software, data is collected depicting the seal strength of the entire length of the seal. As a result, it is possible to see seal strength variations, as the seal is peeled apart, thereby evaluating the consistency and uniformity of the seal (see Fig. 1).1.1 This test method describes a method for the measurement of mechanical seal strength while separating the entire lid (cover/membrane) from a rigid or semi-rigid round container.1.2 This test method differs from Test Method F88. Test Method F88 tests a portion of the seal where as this test method tests the force required to separate the entire lid (cover/membrane) from the container.1.3 This test method is used to determine the continuous and maximum forces required to separate the lid (cover/membrane) from the container.1.4 This test method uses an angle of pull of 45°, however other angles of pull may be used provided results are documented noting the used angle of pull and said procedure is validated.1.5 Typical examples of container shapes that could be tested using this or a similar method include oval, rectangular, and circular with single or multiple cavities having a sealed lid (cover/membrane). Examples of products packaged in these types of containers are: ready meals, creamers, coffee, yogurts, household fresheners, chemical and pharmaceutical products, and numerous others not mentioned. However, this test method, described within, is specifically for round containers.1.6 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.1.7 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.

12.1 The dielectric breakdown voltage of the sleeving is of importance as a measure of its ability to withstand electrical stress without failure. This value does not correspond to the dielectric breakdown voltage expected in service, but is of value in comparing different materials or different lots, in controlling manufacturing processes or, when coupled with experience, for a limited degree of design work. The comparison of dielectric breakdown voltage of the same sleeving before and after environmental conditioning (moisture, heat, and the like) gives a measure of its ability to resist these effects. For a more detailed discussion, refer to Test Method D149.1.1 These test methods cover procedures for testing electrical insulating sleeving comprising a flexible tubular product made from a woven textile fibre base, such as cotton, rayon, nylon, or glass, thereafter impregnated, or coated, or impregnated and coated, with a suitable dielectric material.1.2 The procedures appear in the following sections:Procedures Section(s)   Selection of Test Material 5Conditioning 6Dimensions 7 to 11Dielectric Breakdown Voltage 12 to 17Brittleness Temperature 18 to 21Flammability (See Test Methods D8355) 22 to 23Dielectric Breakdown Voltage After Short-Time Aging 24 to 28Oil Resistance 29 to 32Thermal Endurance 33 to 39Compatibility of Sleeving with Magnet Wire Insulation 40 to 54Solvent Resistance 55 to 60Hydrolytic Stability 61 to 67Effect of Push-Back After Heat Aging 68 to 731.3 The values stated in inch-pound units, except for °C, are to be regarded as the standard. The values in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This is a fire-test-response standard. See Test Methods D8355, which contains procedures for flammability tests.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. For specific hazard statements, see 40.2 and 58.1.1.NOTE 1: This standard resembles IEC 60684-2, Specification for Flexible Insulating Sleeving—Part 2 Methods of Test, in a number of ways, but is not consistently similar throughout. The data obtained using either standard are not necessarily technically equivalent.1.6 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.

This guide covers the criteria for specifying removable insulation covers for surfaces operating in ait at temperatures above ambient. This guide, however, does not cover the criteria for the design of the equipment for which the removable insulation covers are intended for use, nor does this guide establish the applicability of such covers over all surfaces. The insulation cover shall be fabricated from a fibrous insulation material encased in a tailored fabric or wire mesh enclosure, or both. Covers shall adhere to the physical and chemical requirements such as resistance to temperature, chemical resistance, weather resistance, fire endurance, acoustical performance, and service life.1.1 This guide recommends the criteria to be considered in specifying removable insulation covers for surfaces operating in air at temperatures above ambient.1.2 A removable insulation cover is fabricated from a fibrous insulation material encased in a tailored fabric or wire mesh enclosure, or both. The fabric seams are typically held together with thread, metal rings, or staples, or combination thereof. These covers must be designed and fabricated to allow a close fit with tight joints over piping, elbows, flanges, valves, and tanks. They are intended to be easily removed and replaced to allow for periodic access to the surfaces they cover.1.3 In addition to thermal performance, there are other performance requirements of removable covers. These may include, but are not limited to:1.3.1 Temperature exposure,1.3.2 Chemical and weather exposure,1.3.3 Acoustical, and1.3.4 Fire endurance.1.4 The materials from which the cover is made may include, but are not limited to:1.4.1 Insulation media,1.4.2 Fabric, metal mesh enclosure, or foil enclosure,1.4.3 Seam materials (thread, metal hooks, etc.), and1.4.4 Attachment system (hook and loop attachment, straps, wire, etc.).1.5 The shape, size, and physical design of the cover varies depending on the object to be covered. The cover may consist of more than one piece. Pipes, valves, pumps, and flanges are typical objects to be covered. In many cases, on-site measurements need to be made to ensure an acceptable fit.1.6 The values stated in SI units shall be regarded as the standard. The values given in parentheses are provided for information only.1.7 This guide does not intend to establish the criteria required in the design of the equipment over which removable insulation covers are used, nor does this guide establish or recommend the applicability of removable insulation covers over all surfaces.1.8 It is the responsibility of the user, user's agent, or both, to determine applicability of this guide to their specific application and to inform the equipment designer of the intent to insulate so that appropriate design criteria can be established.1.9 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use1.10 This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use
