A buyer receives two quotations for an electric hospital bed. Supplier A writes: Actuator protection: IPX4. Supplier B writes: Electrical system: IPX5. Another supplier simply writes: Waterproof motor. At first glance, the second or third description may appear better. But there is a more important question: What exactly has been rated, under what IP classification, and does that rating apply to the actuator, control box, handset, power supply or the complete bed? For buyers comparing an electric hospital bed, understanding this distinction is important. An IP code is not simply a marketing label meaning: “This hospital bed is waterproof.” A better evaluation process is: Component → IP Code → Solid Ingress Digit → Water Ingress Digit → Test Condition → Rated Component → Intended Environment → Procurement Requirement. The code is used to describe defined levels of protection provided by an enclosure against ingress under specified conditions. In a typical IP code, one position relates to protection concerning solid objects or access, while another relates to protection against water ingress. This is a common misunderstanding. Therefore, IPX4 and IPX5 should not be read as if the X were another protection level. The exact meaning depends on the stated numerical level. The supplier is not communicating a numerical solid-ingress rating in that position through that code. Different numerical levels correspond to different defined test conditions. They refer to different water-ingress test classifications. For a hospital bed buyer, the important point is that this is a specific ingress-protection classification. The rating should be interpreted within its defined conditions and the manufacturer's instructions. It is commonly associated with protection against water jets under the applicable defined test conditions. That wording is too broad. But procurement decisions should not stop there. A specification should match the intended application, cleaning procedures, product design and applicable project requirements. A bed with one component carrying a higher IP rating is not automatically a better hospital bed overall. Electric hospital beds commonly use actuators to create powered movements. The control box manages electrical connections and commands within the bed system. The handset is another electrical interface that may have its own protection characteristics. Depending on the system design, additional electrical components may have separate specifications. Suppose a quotation says: IPX5. That information alone may be incomplete. The buyer should ask: IPX5 for what? It can include: A supplier may list an actuator specification and a buyer may interpret it as a complete-bed specification. For example: Backrest actuator: stated IP rating Height actuator: stated IP rating Control box: stated IP rating Handset: stated IP rating Electrical components may be exposed to environmental conditions that do not exist in a clean laboratory drawing. Hospital equipment may require routine cleaning according to facility procedures and manufacturer instructions. It does not by itself tell staff which cleaning agent to use. Cleaning and disinfection procedures should follow the relevant product instructions and facility requirements. A component can have an ingress-protection rating without that rating answering every material-compatibility question. Especially when a facility uses defined cleaning agents or procedures. It should not automatically be interpreted as a corrosion-resistance specification. Do not use one IP code as evidence for unrelated properties. It does not replace the complete evaluation of an electrical medical product. The exact documentation required depends on the product and destination market. Without a defined rating or test basis, different suppliers may use the word differently. It gives the buyer a defined technical reference to verify. A hospital bed contains many materials, openings, joints and components. The actuator has one IP rating. The control box has another. The handset has another. Therefore, procurement should consider the actual electrical system rather than selecting one attractive specification. The buyer should verify the exact configuration offered. If an actuator model changes, its specifications should be reviewed again. They can have different enclosure designs and technical specifications. Instead of: Electrical system: waterproof. Use clearly identified component information where available. Its actual environment can differ from components installed under the bed platform. Verify its own specification. An IP classification has defined test conditions. If a facility wants to use a particular cleaning process, compatibility should be confirmed. The appropriate requirement depends on the intended product, component, use environment, project specification and applicable requirements. Then ask suppliers to provide evidence for the offered configuration. A procurement specification should be relevant to the intended use. If a requirement has no relationship to the intended application, it may unnecessarily restrict product selection. Is the rating for the actuator, handset, control box or another component? Do not accept “water resistant” as a substitute for the stated technical classification. If not, record the differences. Determine whether the offered configuration matches the project's actual requirements. The exact evidence depends on the procurement and compliance requirements. Supplier A may quote one actuator brand. Supplier B may quote another. Supplier C may use different components depending on the order. If the actuator or control box is substituted after approval, the previously reviewed IP information may no longer describe the actual supplied configuration. Approve the relevant component configuration together with its technical information. It answers: How do the handset, control box, actuators and power system connect? It answers: What does the stated IP rating tell the buyer about ingress protection? Cable routing. Connector identification. Strain relief. Serviceability. It does not repeat wiring architecture. Can the bed be connected correctly to the destination electrical supply? What ingress protection classification applies to the relevant electrical component? Battery backup concerns power availability when mains electricity is unavailable. IP rating concerns ingress protection. X is not a higher numerical grade. Use the actual IP classification. Component rating and whole-bed claim are not automatically the same. The system contains multiple electrical components. Verify it separately. These are different technical characteristics. Again, evaluate that separately. Follow the product's cleaning instructions. Technical specifications should have a reason. The specification should correspond to the final configuration. For example: Motor: waterproof. Identify the component and state the applicable verified IP classification. Do not compare: Supplier A: Waterproof Supplier B: IPX5 Instead compare: Component → Exact Model → IP Classification → Supporting Information → Intended Use Compatibility. If an importer publishes an unsupported “waterproof hospital bed” claim, the wording can become difficult to defend. If the supplied component changes, update the relevant specification where necessary. Ambiguous wording makes supplier comparison more difficult. The project should determine what is actually appropriate for its intended application and applicable requirements. “Is this electric bed waterproof?” Explain the applicable IP rating of the relevant electrical components and the manufacturer's intended cleaning and operating conditions. A buyer evaluating an electric hospital bed may also need to review: A high ingress-protection rating on one component does not answer questions about: Mechanical quality. Safe working load. Bed functions. Caster performance. Side-rail design. Electrical compatibility. Serviceability. Understand the project's actual operating and cleaning conditions. Use applicable project and product requirements. Do not evaluate the actuator alone. Keep the ratings component-specific. Understand what each position represents. Especially cleaning and operating limitations. Verify the offered configuration according to the procurement requirement. Make sure the approved specification matches the production configuration. A different actuator or control box may have different specifications. State what has actually been verified. When an electric hospital bed specification says IPX4, IPX5 or another IP code, do not treat the number as a general quality score. Ask: Which component has this rating? What does each position in the code represent? What test condition does the stated classification describe? Do the actuator, control box and handset have the same or different ratings? Does the supplier mean one component or the complete electric hospital bed? Does the offered configuration match the project's actual operating and cleaning environment? The correct evaluation path is: Component → IP Classification → Test Meaning → Actual Configuration → Intended Environment → Supporting Information → Procurement Decision. Most importantly, avoid turning a component-level IP rating into an unsupported statement that the entire hospital bed is “waterproof.” Technical procurement becomes more reliable when every claim is connected to the exact component it describes.

What Does IP Mean?
IP Refers to Ingress Protection
It is a classification system, not a general quality score
The Code Can Contain Two Character Positions
The two positions describe different characteristics
Why Do Some Ratings Contain an X?
An X Does Not Mean “Extra Protection”
X is not a performance grade
It Indicates That a Numerical Rating Is Not Being Stated in That Position
Read each position correctly
What Does the First Digit Represent?
The First Numerical Position Concerns Solid Ingress and Access Protection
Do not confuse it with water protection
If the Code Uses X in the First Position
Do not invent a missing rating
What Does the Second Digit Represent?
The Second Numerical Position Relates to Water Ingress Protection
Higher numbers represent different and generally more demanding water-exposure classifications, but the exact test condition matters
This Is Why IPX4 and IPX5 Are Not Identical Claims
Compare the actual code, not the word “waterproof”
What Does IPX4 Mean?
IPX4 Is Associated With Protection Against Splashing Water Under Its Defined Test Conditions
It should not be expanded into an unlimited waterproof claim
IPX4 Does Not Mean the Component Can Be Used in Any Wet Environment
Do not convert a classification into a blanket promise
What Does IPX5 Mean?
IPX5 Refers to a Different Water-Ingress Test Condition
Again, the test condition matters
IPX5 Should Not Automatically Be Described as “Completely Waterproof”
Use the actual rating instead of an exaggerated description
Is IPX5 Better Than IPX4?
It Represents a Different and More Demanding Water-Ingress Classification
A higher classification is not automatically the only purchasing criterion
The Buyer Still Needs to Ask What the Project Actually Requires
Requirement first, rating second
Do Not Turn IP Ratings Into a Simple Product Ranking
IP rating describes a particular protection characteristic
Which Parts of an Electric Hospital Bed Can Have an IP Rating?
1. Linear Actuators
Actuator enclosure protection can be relevant
2. Control Box
Its protection specification may differ from the actuators
3. Handset
Do not assume the handset shares the actuator rating
4. Power Supply or Related Electrical Modules
Check the exact configuration
The Most Important Buyer Question: Which Component Has the Rating?
Component identification is essential
Actuator IPX5 Does Not Automatically Mean the Whole Bed Is IPX5
A Hospital Bed Is a System of Multiple Components
One component rating should not automatically be applied to the complete system
This Is a Common Specification Error
Keep component claims and system claims separate
Ask the Supplier to Write the Rating Next to the Component
This is clearer than one isolated IP code
Why Does Ingress Protection Matter on a Hospital Bed?
Hospital Beds Exist in Real Care Environments
Real-world use matters
Cleaning Is One Important Consideration
Electrical components must be used within their intended environmental limits
But IP Rating Does Not Tell You the Entire Cleaning Procedure
An IP Code Is Not a Cleaning Manual
Different question
It Also Does Not Tell Staff How to Disinfect the Complete Bed
Do not derive a complete cleaning protocol from an IP code
IP Rating and Chemical Resistance Are Not the Same Thing
Water Ingress Protection Does Not Automatically Describe Resistance to Every Cleaning Chemical
Separate water ingress from chemical compatibility
Ask for Appropriate Cleaning Instructions
Use manufacturer guidance
IP Rating and Corrosion Resistance Are Also Different
Ingress Protection Describes Enclosure Protection Under Defined Conditions
Different technical characteristics
Frame Coating and Material Selection Need Their Own Evaluation
Keep specifications separate
IP Rating and Electrical Safety Are Not the Same Claim
An IP Rating Addresses Ingress Protection
One classification does not represent every electrical characteristic
Buyers Should Review the Full Applicable Product Documentation
Avoid reducing compliance to one IP number
Why “Waterproof Motor” Is Too Vague for a Technical Specification
What Does Waterproof Mean?
Marketing language can create ambiguity
A Specific IP Classification Is More Useful
Replace vague adjectives with measurable specifications
Do Not Write “Waterproof Hospital Bed” Unless the Claim Is Properly Supported
Whole-product claims require appropriate evidence
Why Buyers Should Ask About Every Major Electrical Component
Imagine This Configuration
The system is not represented accurately by quoting only the highest number
The Weakest Relevant Component May Matter in the Intended Environment
Evaluate the complete configuration
Can Different Actuators on the Same Bed Have Different IP Ratings?
They Can Have Different Specifications Depending on the Selected Components
Do not assume every actuator is identical
This Is Especially Important After Component Substitution
Component changes can change technical characteristics
Can the Control Box Have a Different Rating From the Actuator?
Yes, They Are Separate Components
Check each component individually
The Quotation Should Avoid Ambiguous Statements
Specificity improves procurement control
Can the Handset Be the Most Exposed Component?
The Handset Is Frequently Handled
Location and use matter
Do Not Assume It Has the Same Protection as the Control Box
Component-level checking again matters
Does IPX5 Mean the Bed Can Be Washed With a High-Pressure Cleaner?
Do Not Make That Assumption
It is not permission for every possible cleaning method
Follow the Manufacturer's Cleaning Instructions
Test classification and real cleaning procedure must not be confused
Does IPX4 Mean the Bed Can Never Be Used in a Hospital?
No Universal Conclusion Should Be Made From the Code Alone
Do not invent a universal hospital-bed IP requirement
Procurement Teams Should Define Their Requirement
Specification should follow project need
Should Every Hospital Bed Buyer Demand the Highest Possible IP Rating?
Not Automatically
Higher numbers should not become arbitrary tender requirements
Over-Specification Can Also Create Problems
Specify what the project actually needs
How Should Buyers Compare IPX4 and IPX5 Quotations?
Step 1: Identify the Component
Do not compare unnamed ratings
Step 2: Confirm the Exact Code
Use measurable information
Step 3: Ask Whether All Relevant Components Have the Same Rating
Map the electrical system
Step 4: Review the Intended Cleaning and Use Environment
Application matters
Step 5: Request Supporting Documentation Where Required
Verify rather than assume
Do Not Compare IP Ratings Without Comparing the Exact Product Configuration
The component list matters
IP Rating Should Be Locked With the Approved Electrical Configuration
A Component Change Can Affect the Specification
Technical change control matters
Buyers Should Avoid Generic Approval
Connect specifications to actual components
This Is Different From the Control Box Article
The Control Box Article Explains System Architecture
Electrical architecture
Today's Article Explains Environmental Protection Classification
Environmental resistance
This Is Different From the Cable and Connector Article
The Cable Article Focuses on Wiring
Physical electrical connection
Today's Topic Focuses on Enclosure Protection
Different search intent
This Is Different From Voltage and Plug Compatibility
Voltage Questions Ask
Power compatibility
IP Questions Ask
Environmental protection
This Is Also Different From Backup Battery Questions
