SIL Validation

About Safety Integrity Level (SIL) Validation

Safety instrumented systems and each instrumented function within that system must be tested to ensure that those systems is functioning to the standards for which they are designed. A proof test consists of a set of steps that you need to perform to test safety instrumented systems and instrumented functions. The conditions under which the test is conducted should represent the normal conditions under which the system is intended to operate.

Depending on the group of equipment or devices that make up a safety instrumented system, you will want to define a set of test steps that apply to a given group of equipment or devices. In other words, you will need to define one set of test steps that you can reuse when you test similar systems.

Creating Records in Proof Testing

For each proof test that you want to conduct, you should create at least one record in each of the following families:

  • SIS Proof Test Template : Stores details about a given proof test, including the steps that need to be performed. For each unique set of test steps that exists, you will need to create one SIS Proof Test Template to store those details.
  • SIS Proof Test Template Detail : Stores the details on each specific step that needs to be performed for the test. These records are linked to SIS Proof Test Templates through the Has Template Detail relationship. You should create one SIS Proof Test Template Detail for each step that is required for that test.
  • Inspection Task : Stores the details of the proof test task, which specifies the schedule for the proof test. These records are linked to the asset on which you will perform the proof test and to the Proof Test through the Has Task relationship. After you perform the proof test and the Proof Test that is linked to the asset is closed, the Proof Test Task is updated automatically to reflect the date on which the proof test was performed and the next date on which the proof test is due for that asset. Proof Tests Tasks are also created in Asset Strategy Management (ASM) after you promote a Recommendation to ASM.
  • SIS Proof Test : Stores details about a proof test that you perform, including the test results. When you create an SIS Proof Test, you will need to specify the SIS Proof Test Template that contains the details about the proof test you want to perform. When you select the SIS Proof Test Template, one Functional Test Detail will be created for each SIS Proof Test Template Detail that is linked to the SIS Proof Test Template. For each proof test that you want to perform, you will need to create one SIS Proof Test. You can, however, reuse SIS Proof Test Templates.

You can think of the SIS Proof Test Template and SIS Proof Test Template Details as the specifications for how the test should be performed, and the SIS Proof Test and Functional Test Details as a record of the test occurring.

Steps Involved in Conducting a Proof Test

To conduct a proof test, you will need to complete the following steps:

  1. Define the proof test steps that need to be performed for a given safety instrumented system by creating one Proof Test Template for each type of test that will need to be performed. Creating an SIS Proof Test Template includes linking SIS Proof Test Template Details to the SIS Proof Test Template.
  2. Create one SIS Proof Test, which serves as a record of the test event and stores the results of that test.

This topic provides details on SIS Proof Test Template and SIS Proof Tests. For details on how these families participate in the SIS Management data model, see the SIS Management data model.

About Mobile Proof Tests

You can use Mobile Proof Testing on the GE Digital APM mobile application to run test procedures and collect proof testing data using mobile devices, such as a tablet. You can record values for the Proof Test and create recommendations (e.g., a maintenance follow-up) for the proof test, directly from the mobile device even if the mobile device is disconnected from the network.

When you download a Proof Test Task for offline access, on the Mobile Proof Testing page, the icon appears on the downloaded Proof Test Task, indicating that the Proof Test Task is downloaded to the mobile device that you will use for recording values for the Proof Test.

About Synchronizing Mobile Proof Tests

When you reconnect the mobile device to the network, the values that you recorded in the Proof Tests and the Recommendations that you created are uploaded automatically to the GE Digital APM database.

The color of the icon that appears on the upper-right corner of the Proof Test in the Mobile Proof Testing page, indicates the status of synchronization. The icon changes to one of the following:

  • : Indicates that the synchronization is completed successfully. The values that you recorded in the Proof Test and the associated Recommendations are uploaded to the database.

  • : Indicates that the synchronization failed. When you select , a message appears, describing the error that has caused the synchronization to fail. The error may be either in the Proof Test or in the Recommendation.

On successful synchronization, GE Digital APM copies the values in the Proof Tests that you executed in the mobile device to the corresponding Proof Tests in the database. You can access these Proof Tests from the SIS Management module.

GE Digital APM system creates copies of the Recommendations that you created in the mobile device, and then links them to the Instrumented Functions with which the Proof Test Tasks are associated. The images attached to the Recommendations that you created for the Proof Test appear as Reference Documents in the Recommendations created for the Instrumented Function.

Tip: For more information, refer to the Reference Documents section of the documentation.

Safety Integrity Level (SIL) Validation Workflow

This workflow provides the basic, high-level steps for performing an SIL validation. The steps and links in this workflow do not necessarily reference every possible procedure.

Performing an SIL Verification includes the following steps:

  1. Create a Proof Test Template, which stores the details of the pass/fail criteria and error limits.
  2. Create a Proof Test Task, which stores the schedule for the task.
  3. Perform the proof test.
  4. Create a Proof Test.
  5. Apply the Proof Test Template and the Proof Test Task to the Proof Test.
  6. In the Proof Test record, provide the results of the proof test that you have performed.
  7. The GE Digital APM system performs the error calculations and provides the pass/fail results.
