ASTM D1 41 5, Tentative Method of Testing for International Hardness of Vulcanized Natural and Synthetic Rubbers ASTM D1 708, Standard Test Method for Tensile Properties of Plastics by Use of Microtensile Specimens ASTM D21 40, Standard Practice for Calculating Carbon-Type Composition of Insulating Oils of Petroleum Origin ASTM D2240, Standard Test Method for Rubber Property—Durometer Hardness ISO 37 3 , Rubber, vulcanized or thermoplastic—Determination of tensile stress–strain properties ISO 2859-1 , Sampling procedures for inspection by attributes—Part 1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection ISO 3601 -1 , Fluid power systems—O-rings—Part 1: Inside diameters, cross-sections, tolerances and designation codes ISO 3601 -3, Fluid power systems—O-rings—Part 3: Quality acceptance criteria ISO 971 2, Non-destructive testing—Qualification and certification of NDT personnel 3 Terms and Definitions For the purposes of this document, the terms and definitions given in API Q1 and the following apply. 3.1 assembly Product comprised of more than one component. 3.2 base elastomer An elastomer family of materials with common property limits such as HNBR, FKM, EPDM. 3.3 base elastomer formulation A base elastomer mixed with additives to achieve physical properties that enhance performance. 3.4 bridge plug Mechanical device used for blocking fluid (liquid or gas) communication within a conduit when installed (not installed in a design receptacle or conduit). 3.5 component An individual part of an assembly. 3.6 conduit Casing, tubing or liner, metallic, or nonmetallic.
5.5 Environmental Compatibility 5.5.1 General It is the equipment user/purchaser’s responsibility to ensure that any material specified for use is satisfactory in the service environment. If the user/purchaser has access to data of the operating environment based on historical information and/or research, then it should be stated to the supplier/manufacturer which material(s) have the ability to perform as required within the environment. Otherwise, material compatibility shall be specified according to supplier/ manufacturers selection criteria. If material qualifications are required outside of or additional to NACE MR01 75/ ISO 1 51 56 or other specified material standard, the parameters as defined in 5.4 are required. 5.5.2 Well Environment The user/purchaser should identify the density, chemical/physical composition, and the condition of the fluid and/or its components, including solids (sand production, scale, salinity, etc.), liquid, and/or gaseous, to which the openhole device is exposed during each portion of its expected life cycle. Fluid exposure durations, temperatures, and pressures should be included. Include chemical stimulations as well as changes in fluid composition over time (acid stimulation, injection water compositions, H 2 S and CO 2 , etc.)
6 Technical Specification 6.1 General The supplier/manufacturer shall prepare and provide to the user/purchaser the technical specification that demonstrates that the equipment meets the requirements of the functional specification. Products conforming to this specification shall be manufactured to drawings and specifications that are substantially the same as those of the same size type and model that has been validated. Products that are validated by design scaling shall also conform to the scaling requirements in Annex B and Annex C. If the technical specification does not fully meet the functional requirements, the supplier/manufacturer shall identify the differences to the user/purchaser. The supplier/manufacturer shall also provide to the user/purchaser the product data sheet as defined in 7.2.3. The design of products manufactured to this Specification shall include documentation of those designs. This documentation shall include, as applicable, design requirements, assumptions, analysis methods, comparison with previous designs or operating history of similar products, calculations, manufacturing drawings and specifications, design reviews, and/or physical testing results (such as design validation testing). 6.2 Technical Characteristics The product shall be designed to perform in accordance with the functional specification and the defined technical characteristics during installation, activation, and operation. 6.3 Design Requirements Each packer or bridge plug design shall be analyzed and verified to determine the supplier/manufacturer’s performance ratings. The minimum material condition and minimum material yield strength shall be used in the calculations.
