Pressure gauge EU CE-ROHS test report

：【question】 Visits：
Pressure gauges exported to the EU must simultaneously meet CE certification (under the Pressure Equipment Directive PED 97/23/EC) and RoHS hazardous substance testing requirements. Below is the complete process, standard requirements, and core information for CE-RoHS testing reports:
I. CE Certification (Pressure Equipment Directive PED 97/23/EC)
1. Applicable Standards and Compliance Basis
Core Directive: Pressure gauges are pressure accessories and fall under the control of the EU PED Directive 97/23/EC. All pressure gauges with a design pressure > 0.5 bar must obtain CE certification.
Testing Standards: Mandatory compliance with EN837 series standards:
EN837-1: Requirements for dimensions, measurement techniques, accuracy, and safety protection of Bourdon tube pressure gauges
EN837-2: Selection and installation specifications for pressure gauges
EN837-3: Specific testing requirements for diaphragm/capsule pressure gauges
Compliance Path Division: Determined based on the product of pressure and volume (Ps×V):
If Ps×V＞50: Must comply with the basic safety requirements of PED Annex I, and certification must be issued by an EU Notified Body (NB).
If Ps×V≤50: Manufactured using reasonable engineering practices, affixing the PED Annex II mark is sufficient; no Notified Body involvement is required.
2. Core Testing Items
| Category | Test Content
| Metrological Performance | Total indication error (must meet accuracy class requirements, e.g., Class 1 gauge error ≤ ±1%), hysteresis, temperature effect error testing
| Mechanical Performance | Impact test (maintaining accuracy after 150m/s² impact), durability test (75% pressure cycle test at full scale)
| Safety Protection | Pressure component failure protection (preventing high-pressure gas leakage and fragment ejection)
| Additional tests for special models | Electrical contact pressure gauges require additional testing for LVD (Low Voltage Directive) (electrical safety) and EMC (Electromagnetic Compatibility Directive) (interference immunity)
II. RoHS Hazardous Substance Testing
1. Scope of Application
Pressure gauges with electronic components (such as electrical contact pressure gauges and digital display pressure gauges) are RoHS-regulated electronic and electrical equipment and must undergo mandatory testing.
Purely mechanical pressure gauges containing electroplated layers or plastic parts (dial, gaskets) also require RoHS testing for the contact materials.
2. Test Items and Limits
| Material Type | Test Items
| Metal Parts (steel/aluminum casing, movement) | Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr⁶⁺)
| Non-metallic Parts (plastic, coating) | 4 Heavy Metals + Polybrominated Biphenyls (PBBs), Polybrominated Diphenyl Ethers (PBDEs) + Phthalate Esters (DEHP/BBP/DBP/DIBP)
III. CE-RoHS Test Report Process
1. Preliminary Preparation
CE Certification Documents: CE application form, product technical parameters, design drawings (mechanical/circuit diagrams), risk assessment report, production process description
RoHS Testing Documents: Bill of Materials (BOM), sample disassembly instructions (marking metal/non-metal parts)
Sample Requirements: CE testing requires 3-5 complete pressure gauges (including accessories); RoHS testing requires 500g of metal parts/20-30g of non-metal parts (disassembled by material)
2. Testing and Audit Stage
1. Application Submission: Submit documents and samples to an EU-accredited third-party testing organization (such as DEZEW Testing CNAS registration number: L8083)
2. Specialized Testing:
CE Section: Metrological performance and mechanical safety tests are completed according to EN837 standards. LVD/EMC testing is added for electrical contact meters.
RoHS Section: Hazardous substance content is detected using XRF spectroscopy and chemical analysis.
3. Report Preparation: Integrate CE certification test data and RoHS test results to issue an English report compliant with EU regulations.
4. Certification: Obtain a CE certificate upon successful CE certification. A RoHS test report is issued upon successful RoHS testing. Both can be combined into a single CE-RoHS integrated report.
3. Report Validity and Updates
CE certification needs to be updated promptly with revisions to the PED directive and EN837 standards. A review every 3 years is generally recommended.
RoHS test reports are valid indefinitely if the product material and manufacturing process remain unchanged. If RoHS regulations add new controlled substances, the corresponding items need to be tested.
IV. Amazon/EU Customs Clearance Notes
1. The CE mark must be affixed to a prominent position on the pressure gauge and must perfectly match the product model in the report.
2. 3. The CE certification report for electrical contact pressure gauges must clearly indicate compliance with the LVD/EMC directives.
4. RoHS test reports must break down test data by material type; a general "qualified" conclusion is insufficient.
5. If Ps×V > 50, the CE certificate must include the number of an EU Notified Body (NB); otherwise, customs clearance will be impossible or penalties will be imposed by EU market regulators.
