Measurement Functions of Silver Scale ™
By registering the measurement results of the Silver Scale™, you can perform analysis.
Overview of Silver Scale ™
■Capabilities of Silver Scale™
Visually identify corrosion risks (hydrogen sulfide and sulfur).
Determine the corrosion category in compliance with ISO 11844-1 based on the installation period and corrosion length of the Silver Scale™.
Assess the impact of the corrosion category on equipment.
(Reference: ISO 11844-1 standard, ANSI/ISA 71.04-2013 standard)
| Indoor Corrosion Categories | Impact on equipment | |
|---|---|---|
| IC1 | - Very low indoor corrosivity | - Environment sufficiently controlled to ensure that corrosion is not a factor in determining equipment reliability |
| IC2 | - Low indoor corrosivity | |
| IC3 | - Moderate indoor corrosivity | - Environment where corrosion may be a factor in determining equipment reliability |
| IC4 | - High indoor corrosivity | |
| IC5 | - Very high indoor corrosivity | - Environment where the probability of corrosion attack is high |

■Diagnostic Method
STEP 1 : Installation
Remove the Silver Scale™ from the bag and place it at the desired measurement location.
* Please open the aluminum moisture-proof bag just before measurement.
* Ensure that the aperture is not blocked during installation.
* Place it in a location where water cannot enter through the aperture.
STEP 2 : Record
Record the installation start date.
STEP 3 : Observation
After the designated period (e.g., 30 days, up to a maximum of 1 year), record the serial number, observation date, corrosion length (mm), and take a photo.
*Measure the corrosion length by recording the length that has turned yellow.*
STEP 4 : Analysis
Log in to our website and enter the recorded information.
You can determine the corrosion category based on the ISO 11844-1 standard.
*If the corrosive gas (hydrogen sulfide, sulfur) is unknown, select hydrogen sulfide as the corrosion type for the analysis.
*You can perform up to 4 analyses, and the observation period is up to 1 year.
