1. ability of fire dampers installed in ventilation systems to prevent the spread of fire and heat through designated fire divisions; typical ratings are given in ISO 13702:1999, Table C.5.
2. fire damper operational reliability in the petroleum, petrochemical and natural gas industries, particularly offshore installations;
3. ability of fire dampers installed in ventilation systems to withstand blast overpressures that may result from the explosion of a flammable gas.

ISO/TS 27469:2010 applies to different start-up operations for different types of furnace and, therefore, tolerances in test conditions at the beginning of the test are not described in detail. The fire test enables only a limited assessment of the actuating mechanism being carried out and additional tests can be necessary to fully evaluate its operational reliability.

The operational phase is considered to extend from handover of the well after construction, to handover prior to abandonment. This represents only the period during the life cycle of the well when it is being operated.

ISO/TS 16530-2:2014 includes:

? A description of the processes required to assess and manage risk within a defined framework. The risk assessment process also applies when deviating from ISO/TS 16530-2:2014.

? The process of managing well integrity by operating wells in compliance with operating limits for all well types that are defined based on exposure of risk to people, environment, assets and reputation. The management of well integrity is supported by associated maintenance/monitoring plans, technical reviews and the management of change.

? The assessment of existing assets (wells / fields) in order to start the process of Well Integrity Management in accordance with ISO/TS 16530-2:2014.

? The handover process required when changing from one activity to another during the operational phase.

ISO/TS 16530-2:2014 applies to all wells that are utilized by the oil and gas industry, regardless of their age, type or location.

NOTE This document can be considered complementary to ISO 13679 (and its core content per API Specification 5C5), which applies to classic elastic-design applications.

This document contains an evaluation procedure for a candidate connection comprising of uniquely defined pin, box and interfacial components. The evaluation procedure includes:

—    Material property tests to assess relevant properties of the candidate connection pin and box components;

—    Analytical tasks to determine configuration of connection samples for physical tests, which are chosen based on worst-case combinations of the connection geometry and material properties;

—    Full-scale testing tasks to measure the candidate connection galling resistance, structural integrity and sealability under loading representative of connection assembly and thermal well service.

This document does not address impacts of external pressure, incomplete lateral pipe support, rotational fatigue, formation-induced shear, or environmentally-induced corrosion or cracking.

Clause 6 describes fundamental assumptions adopted in this document.

For equations related to performance properties, extensive background information is also provided regarding their development and use.

Equations presented in ISO/TR 10400:2007 are intended for use with pipe manufactured in accordance with ISO 11960 or API 5CT, ISO 11961 or API 5D, and ISO 3183 or API 5L, as applicable. These equations and templates may be extended to other pipe with due caution. Pipe cold-worked during production is included in the scope of this Technical Report (e.g. cold rotary straightened pipe). Pipe modified by cold working after production, such as expandable tubulars and coiled tubing, is beyond the scope of this Technical Report.

Application of performance property equations in ISO/TR 10400:2007 to line pipe and other pipe is restricted to their use as casing/tubing in a well or laboratory test, and requires due caution to match the heat-treat process, straightening process, yield strength, etc., with the closest appropriate casing/tubing product. Similar caution should be exercised when using the performance equations for drill pipe.

ISO/TR 10400:2007 and the equations contained herein relate the input pipe manufacturing parameters in ISO 11960 or API 5CT, ISO 11961 or API 5, and ISO 3183 or API 5L to expected pipe performance. The design equations in ISO/TR 10400:2007 are not to be understood as a manufacturing warrantee. Manufacturers are typically licensed to produce tubular products in accordance with manufacturing specifications which control the dimensions and physical properties of their product. Design equations, on the other hand, are a reference point for users to characterize tubular performance and begin their own well design or research of pipe input properties.

ISO/TR 10400:2007 is not a design code. It only provides equations and templates for calculating the properties of tubulars intended for use in downhole applications. ISO/TR 10400:2007 does not provide any guidance about loads that may be encountered by tubulars or about safety margins needed for acceptable design. Users are responsible for defining appropriate design loads and selecting adequate safety factors to develop safe and efficient designs. The design loads and safety factors will likely be selected based on historical practice, local regulatory requirements, and specific well conditions.

All equations and listed values for performance properties in ISO/TR 10400:2007 assume a benign environment and material properties conforming to ISO 11960 or API 5CT, ISO 11961 or API 5D, and ISO 3183 or API 5L. Other environments may require additional analyses, such as that outlined in Annex D.

Pipe performance properties under dynamic loads and pipe connection sealing resistance are excluded from the scope of ISO/TR 10400:2007.

— pipe performance properties, such as axial strength, internal pressure resistance and collapse resistance,

— minimum physical properties,

— product assembly force (torque),

— product test pressures,

— critical product dimensions related to testing criteria,

— critical dimensions of testing equipment, and

— critical dimensions of test samples.

ISO/PAS 12835:2013 describes the structure of the Thermal Well Casing Connection Evaluation Protocol (TWCCEP) and provides guidelines for its use by new or repeat TWCCEP users, whose familiarity with the TWCCEP provisions might vary. Clause 6 describes fundamental assumptions adopted in the TWCCEP.
