#### Pressure Relief Valve Test Record

Serial: {{serial}}
Manufacturer / model: {{mfr}}
Size / orifice: {{size}}
Test date: {{date}}

#### Test Basis

**Body:** Set pressure: {{set}} psig
Cold differential test pressure: {{cdtp}} psig
Tolerance: {{tol}}
Test medium: {{medium}}

#### Results

**Body:** As-found popping pressure: {{as_found}} psig
As-left popping pressure: {{as_left}} psig

#### Seat Tightness and Condition

**Table:**

**Columns:**

- Check
- As found
- As left
- Notes

**Rows:**

**0:** Seat tightness at 90% of set

**0:** Visual condition (corrosion, deposits)

**0:** Spring and guide condition

**0:** Blowdown ring setting

#### Repairs and Adjustments

**Body:** {{work}}

#### Approval

**Signatures:**

- Test technician
- Inspector
- Customer representative

**Notes:** Use the tolerance and seat tightness criteria from your repair procedure, the customer's requirement or the applicable code such as API 527. The 90 percent test point above is a common convention, not a universal rule. Gauges used for testing must be calibrated and traceable.

## Content

**Intro:** Every relief valve that comes through a test shop needs a record that shows what it popped at when received and when released. This template captures the identification, set pressure data, as-found and as-left results and repairs on a single page.

**Sections:**

#### How to use this template

**Body:** Enter the tag, serial number, manufacturer and orifice. Fill in the set pressure and cold differential test pressure, which accounts for back pressure or service temperature on the nameplate. Record the as-found popping pressure before any cleaning or adjustment, then the as-left value after repair. Complete the seat tightness table, describe the work done, and export the record for the valve tag and the plant's PSV register.

#### Understanding as-found versus as-left

**Body:** The as-found result tells the operator whether the valve would have protected the equipment while in service, so a high as-found pop is a reliability finding, not only a repair detail. The as-left result proves that the valve now meets its set pressure within tolerance. Set pressure on the nameplate is the service value, while the cold differential test pressure compensates for back pressure and operating temperature when the bench test runs at ambient conditions.

**Bullets:**

- Record as-found first, before touching the valve
- Never discard an as-found reading that is out of tolerance
- Use the same gauge for as-found and as-left tests where possible
- Seal the adjusting screw and tag the valve after the final test

#### Common mistakes

**Body:** The common errors are testing at the service set pressure instead of the cold differential test pressure, recording only the final result, and issuing a record with no gauge calibration reference. Another is mixing up tags when several identical valves are in the shop at once. Use a physical tag at receiving, and photograph the nameplate as part of the record.

**Cta:** If PSV test dates and due dates live in spreadsheets, we can help connect them to your ERP or maintenance system so overdue relief valves surface automatically.

**Faq:**

#### What is a cold differential test pressure?

**Answer:** It is the pressure at which the valve is set on the bench so that it opens at the correct set pressure in service. It adjusts for back pressure and for the difference between ambient and operating temperature.

#### Why record the as-found pressure?

**Answer:** Because it shows how the valve behaved in service. If it opened well above set pressure, the plant should evaluate whether the protected equipment was at risk and whether the test interval should be shortened.

#### What medium should I use?

**Answer:** Use the medium specified by your procedure and the valve type. Gas and vapor valves are normally tested with air or nitrogen, steam valves with steam, and liquid valves with water.

#### How often are PSVs tested?

**Answer:** The interval depends on the code, jurisdiction and the plant's risk-based inspection program. Your inspection authority or API 510 and related practices set the maximum, so use the interval from your own program.
