Which international standards should I reference when selecting water monitoring equipment? What are ISO 4064, OIML R49, and IEC 60068?
Three core standards: ISO 4064 (water meter metrology), OIML R49 (international trade compliance), IEC 60068 (extreme environment reliability). All CSSOC products certified, -25~+70°C operating range, IP68 rated. Essential reference for international buyers.
When selecting water monitoring equipment, the following international standards are critical benchmarks:
ISO 4064 (Water Meter Standard): Specifies metrological and technical requirements for water meters in closed conduits (including electromagnetic and ultrasonic types), covering accuracy classes (Class 1/2), pressure loss, and durability testing. CSSOC LGF electromagnetic flowmeters meet ISO 4064 Class 1 accuracy.
OIML R49 (International Recommendation for Water Meters): Type evaluation and verification standard from the International Organization of Legal Metrology. OIML R49 compliance is a "passport" for water meter products in global trade — compliant products can be directly sold in most countries worldwide.
IEC 60068 (Environmental Reliability): Defines testing methods for electronic equipment under temperature extremes, humidity, vibration, shock, and salt spray. All CSSOC products pass IEC 60068 testing and operate reliably from -25°C to +70°C at 95% humidity.
Additional relevant standards: IEC 60529 (IP rating — CSSOC products rated IP68), IEC 61000 (electromagnetic compatibility), ISO 17025 (calibration laboratory competence).
Understanding these standards helps international buyers accurately evaluate equipment capabilities and make informed procurement decisions.
