Introduction: Why Standards Matter in Pressure Gauges
In every industrial process, from oil and gas pipelines to chemical plants and manufacturing systems, pressure gauges play a critical role in monitoring and safety.
Yet, one of the most common reasons for equipment malfunction and inaccurate readings is the use of gauges that do not meet the correct standard.
Different regions follow different benchmarks — IS (Indian), EN (European), ASME (American), and JIS (Japanese) — each with unique specifications for design, accuracy, and performance.
For B2B buyers, OEMs, and plant engineers, understanding these standards ensures reliability, safety, and long-term operational value.
At AIMS Controls, we simplify this process by offering standard-compliant pressure gauges designed for diverse industrial environments.
What Are Pressure Gauge Standards and Why Do They Matter?
Pressure gauge standards define how instruments perform under real operating conditions.
They establish parameters for accuracy, safety, design, and testing, ensuring the gauge performs consistently in demanding environments.
Key benefits of using standard-compliant gauges include:
- Improved accuracy and repeatability
- Enhanced operational safety
- Compatibility with global systems and fittings
- Reliable performance in temperature and vibration variations
- Simplified compliance with audits and export regulations
When your gauge meets the correct standard, it fits better, performs longer, and protects your process from costly downtime.
Major Pressure Gauge Standards Explained
Indian Standard (IS 3624)
The Bureau of Indian Standards specifies IS 3624:1987 for dial-type pressure and vacuum gauges used in industrial applications.
It defines design, material, and calibration requirements to ensure measurement accuracy and product safety.
Key features:
- Units: Pa, kPa, or bar
- Accuracy classes: 0.25 to 4.0%
- Sizes: 50, 63, 100, 150, 200, 250 mm
- Mandatory markings and calibration intervals
IS 3624 gauges are ideal for Indian plants, utilities, and OEM applications.
AIMS Controls supplies BIS-certified gauges that meet Indian industry standards and deliver dependable readings under local conditions.
European Standard (EN 837-1)
EN 837-1 governs Bourdon tube pressure gauges across Europe and global export markets. It emphasizes safety, consistency, and accuracy in both design and operation.
Key features:
- Units: bar
- Metric case sizes: 40 to 250 mm
- Accuracy: ±1.0%, ±1.6%, ±2.5% of full scale
- Safety design: blow-out back, solid front, safety glass
EN-compliant gauges are widely used in the chemical, process, and energy industries.
AIMS Controls offers EN 837-1 certified gauges designed for precision, metric compatibility, and export-oriented projects.
American Standard (ASME B40.100)
ASME B40.100 is the principal American standard for pressure gauges. It defines design, performance, and safety criteria for instruments used in US and global installations.
Key features:
- Units: psi
- Thread type: NPT
- Accuracy grades: 4A (0.1%) to C (3%)
- Recommended operating range: 25%–75% of full scale
- Emphasis on safety case construction and overpressure protection
ASME gauges are common in refineries, offshore rigs, and process plants.
AIMS Controls provides ASME-compliant gauges that integrate seamlessly with US-based equipment and meet international safety requirements.
Japanese Standard (JIS B 7505 / B 7547)
The Japanese Industrial Standard (JIS) defines detailed specifications for pressure gauges and calibration procedures, ensuring precise performance in high-accuracy applications.
Key features:
- Units: MPa or bar
- Metric threads and dimensions
- Calibration-focused procedures for performance validation
- Widely used in precision manufacturing and Japanese OEM machinery
AIMS Controls offers gauges designed and tested per JIS requirements for customers using Japanese equipment or exporting to Japanese markets.
Comparison: IS vs EN vs ASME vs JIS
| Standard | Units | Threads | Accuracy Format | Typical Use | Region |
| IS 3624 | bar / kPa | Metric | 0.25–4.0% | Indian plants, OEMs | India |
| EN 837-1 | bar | Metric | ±% FS (1.0, 1.6, 2.5) | Process & export projects | Europe |
| ASME B40.100 | psi | NPT | Grades (4A–C) | Refineries, US-based systems | USA |
| JIS B 7505 | MPa / bar | Metric | Calibration-based | Japanese OEMs | Japan |
Always confirm that your gauge’s thread, unit, and accuracy class match the system it’s installed in. Mismatched gauges can lead to leaks, false readings, and compliance failures.
Why Standard Compliance Matters for Industrial Buyers
Choosing a compliant gauge ensures process reliability and protects both your equipment and workforce.
In most cases, a correctly specified gauge saves up to three times the total cost over its operational life.
