Applicable requirements
Identify destination law, machine category, customer specifications, utility rules and relevant standards.
Standards & responsibility
Standards, Verification and Scope Boundaries
A transparent map of applicable requirements, evidence, customer responsibilities and limits of workshop verification.
Request technical reviewDIRECT ANSWER
The applicable standard set depends on the machine, assembly, destination and customer specification. Referencing IEC 60204-1, IEC 61439, IEC 61800-5-1 or IEC 60529 does not itself prove certification or project compliance.
01Does an IEC reference mean the panel is certified?
No. A standard reference describes a technical basis only. Certification, conformity assessment and project compliance require the applicable scope and supporting evidence.
02Who is responsible for machine safety?
The responsibility must be defined contractually. Panel supply or PLC programming alone does not replace the machine risk assessment and final functional-safety validation.
03What is the difference between FAT and SAT?
FAT checks agreed workshop-available evidence. SAT checks installation and functions with field equipment at site. Final process and safety validation may go beyond both.
Engineering decision framework
Define applicable requirements first
For standards, verification and scope boundaries, the quotation and technical response should address applicable requirements, iec 60204-1, iec 61439 and the remaining project boundary. Missing inputs are recorded as assumptions before selection or design release.
IEC 60204-1
May inform machine electrical equipment; applicability and the boundary from supply connection to machine must be confirmed.
IEC 61439
May inform low-voltage assembly design and verification; the required assembly scope and evidence must be defined.
Drives and enclosures
IEC 61800-5-1 and IEC 60529 may inform drive safety and IP classification, but installation determines final performance.
Responsibility matrix
Separate customer, Honghao, machine builder, software, safety and site responsibilities in the quotation.
FAT, SAT and validation
Workshop FAT, site acceptance and final machine validation prove different things and require separate plans.
Planning input
Boundary questions before quotation
Compliance language is used only when the agreed evidence supports it.
- Destination and installation location
- Machine or assembly category
- Customer and local specifications
- Required certification or third-party involvement
- Functional-safety and risk-assessment owner
- FAT, SAT and final acceptance authority
Common buyer questions
Engineering answers before the RFQ
These answers cover the questions buyers usually ask when evaluating standards, verification and scope boundaries. Final product identity, ratings and deliverables are still verified against the complete article number and agreed project data.
Does an IEC reference mean the panel is certified?
No. A standard reference describes a technical basis only. Certification, conformity assessment and project compliance require the applicable scope and supporting evidence.
Who is responsible for machine safety?
The responsibility must be defined contractually. Panel supply or PLC programming alone does not replace the machine risk assessment and final functional-safety validation.
What is the difference between FAT and SAT?
FAT checks agreed workshop-available evidence. SAT checks installation and functions with field equipment at site. Final process and safety validation may go beyond both.
Can local destination requirements be included?
Yes when they are identified early, supplied in usable form and included in the agreed design, procurement, verification and documentation scope.
Scope boundary
Workshop review and FAT do not replace machine risk assessment, final site wiring verification, process commissioning, local authority acceptance or functional-safety validation unless these items are separately contracted and documented.
