- The 24 domains reproduce Festo preparation-curriculum topics: Domains 1-17 cover pneumatics, Domains 18-24 cover hydraulics.
- No official percentage weights were verified, so treat every domain as testable rather than guessing which ones count most.
- Pneumatics and Hydraulics are separate Festo/NC3 Level 1 credentials, not one combined examination.
- Earning either credential requires an NC3-certified instructor, completed hands-on labs, and a score of at least 70%.
What the 24 Content Areas Actually Are
The Festo Industry Certification Program (FICP) Level 1 Fundamentals credentials are delivered through the National Coalition of Certification Centers (NC3), usually via participating schools and training institutions. Festo publishes preparation documents for both branches: Fundamentals of Fluid Power-Pneumatics (document 272393) and Fundamentals of Fluid Power-Hydraulics (document 272394), both dated EN 2025.09. The 24 headings in this guide come from those curriculum topics, listed in sequence.
Be clear about what that does and does not mean. These 24 lines are unweighted preparation topics. They are not a verified formal exam blueprint, and no official percentage per domain has been confirmed. The count of 24 simply reflects how many headings the curriculum supplies, not a guaranteed exam-domain count or a promise of exhaustive coverage. If you want a bigger-picture orientation first, start with What Is FFPPH? and then return here for the topic-by-topic breakdown.
Two Branches, Not One Combined Exam
FFPPH on this site refers to Fundamentals of Fluid Power - Pneumatics/Hydraulics, and the slash matters. Pneumatics and Hydraulics remain distinguishable credentials. Virginia's CTE Resource Center, for example, lists them as separate records, each with 50 test items, school-administered online delivery, instructor-determined timing, a 70% passing score, and no cost per test. Those are individual school-testing records, so do not assume a single combined 100-question sitting.
| Feature | Pneumatics branch | Hydraulics branch |
|---|---|---|
| Curriculum document | 272393 (EN 2025.09) | 272394 (EN 2025.09) |
| Domains in this guide | 1-17 | 18-24 |
| Published learning structure | 4 units, 12 labs | 3 units, 12 labs |
| Virginia school record | 50 items, 70% to pass | 50 items, 70% to pass |
The unit and lab counts are training quantities. They describe how the course is organized, not how long the written exam lasts or how any practical assessment is timed. For the full picture of how hard each branch feels in practice, see How Hard Is the FFPPH Exam?
Domains 1-5: Pneumatic Foundations
The opening domains establish the vocabulary and math that every later topic leans on. Rushing past them is the most common reason candidates stumble on circuit questions later.
Domain 1: Safety practices for working with pneumatic systems
Compressed air stores energy, and the curriculum treats safe handling as a foundation, not an afterthought.
- Know why depressurizing before disconnecting or servicing matters
- Understand hazards from stored pressure, moving cylinders and loose lines
- Expect scenario questions asking what to do first, not just what is dangerous
Domain 2: Basis design principles for creating pneumatic systems
The source curriculum spells this heading "Basis," and we retain that wording. It covers how a pneumatic system is organized from air supply through conditioning, control and actuation.
- Trace the signal path from supply to actuator
- Separate the power section from the control section
- Recognize the role of air preparation components
Domain 3: Pascal and Boyle's Laws
Pascal's law (pressure transmitted equally through a confined fluid) and Boyle's law (pressure and volume relationship for a gas at constant temperature) explain why pneumatics behaves as it does.
- Be able to apply Boyle's law to compression and volume change
- Use Pascal's law to reason about force at different piston areas
- Notice that these laws reappear in the hydraulics branch
Domain 4: Single-acting and double-acting cylinders
Cylinders convert air pressure into linear motion. The comparison is a classic exam theme.
- Single-acting: air drives one direction, a spring returns the piston
- Double-acting: air drives both directions, so the return stroke is powered
- Know which suits a given application and why
Domain 5: Calculating basic parameters
The core relationship is force equals pressure times area. Expect to work with piston area, pressure units and the difference between extend and retract forces on a double-acting cylinder.
- Remember the rod reduces effective area on the retract side
- Keep units consistent before calculating
- Practice rearranging the formula to solve for pressure or area
Domains 6-12: Valves, Actuation and Control
This is the densest stretch of the pneumatics branch, and it is where schematic reading becomes unavoidable. Domains 6 through 9 build toward being able to look at a circuit and predict what it does.
Actuation and valve fundamentals (Domains 6-8)
Domain 6, Direct and indirect actuation: Direct control drives the cylinder through a valve operated by the operator or a single signal. Indirect control uses a signal valve to switch a larger power valve, which suits larger cylinders and remote control. Know when each makes sense.
Domain 7, 3/2 and 5/2-way valves: The numbers describe ports and positions. A 3/2 valve typically supplies a single-acting cylinder, while a 5/2 valve controls a double-acting cylinder. Be fluent in what each port does in each position.
Domain 8, Methods of actuation of directional control valves: Manual, mechanical, pneumatic and electrical actuation each have symbols and use cases. You should be able to identify the actuation type from its schematic symbol.
Reading and measuring circuits (Domains 9-12)
Domain 9, Analyzing circuits: The integrating skill. Given a diagram, state the sequence of events, identify faults, or explain what changes if a component is swapped.
Domain 10, Options for pressure measurement: Know what gauges and pressure sensing options exist and where they are placed in a system.
Domain 11, Pressure-dependent control systems: Systems where a pressure threshold triggers an action, such as a pressure sequence valve or pressure switch.
Domain 12, Distinguishing flow control: Throttle and one-way flow control valves regulate cylinder speed. Understand the difference between restricting supply air and restricting exhaust air, and why exhaust throttling usually gives steadier motion.
Domains 13-17: Logic, Limit Switches, Timing and Cost
Domain 13: Logic operations (AND/OR/NOT)
Pneumatic logic uses valves to implement logical functions.
- AND: both signals must be present (two-pressure valve behavior)
- OR: either signal is enough (shuttle valve behavior)
- NOT: an inverted signal, achievable with a normally open valve arrangement
Domain 14: Function and application of limit switches
Limit switches detect cylinder position and generate the signal that triggers the next step in a sequence. They are central to automatic and reciprocating circuits.
Domain 15: Time delay valves
A time delay combines a flow restriction, a small reservoir and a valve to delay a signal. Know the building blocks and how to describe the delay behavior.
Domain 16: Realizing oscillating movement
Continuous back-and-forth cylinder motion, typically built from limit switches and a 5/2 valve. This domain ties together Domains 7, 9 and 14.
Domain 17: Economic considerations of using pneumatic components
Not every question is about how a circuit works. Some ask whether pneumatics is the sensible choice, and what drives cost, such as air consumption and component selection.
Domains 18-24: The Hydraulics Branch
The hydraulics domains share concepts with pneumatics, but liquids are essentially incompressible, so behavior, components and calculations differ. Candidates who treat hydraulics as "pneumatics with oil" tend to miss the nuance. A broader overview of the credential family is in FFPPH Certification.
Domain 18: Equipment and circuit diagram symbols, reading basic hydraulic circuit diagrams
Hydraulic symbols differ from pneumatic ones in important ways, such as the filled triangle for hydraulic energy.
- Identify pumps, motors, cylinders, valves and reservoirs by symbol
- Trace flow paths through a simple circuit
Domain 19: Physical principles of hydraulics
Pascal's law returns as the central idea, along with pressure, force, area and flow relationships. Hydraulic force multiplication is a standard concept.
Domain 20: Structure and mode of operation of basic components
Pumps, cylinders, valves, filters and reservoirs: what each does and how it is built.
Domain 21: Measure volumetric flow and pressure
Hands-on measurement is explicitly part of the curriculum. Know the instruments, where they connect and what readings mean.
Domain 22: Technology and characteristic data of valves and drive elements
Interpreting characteristics of valves and actuators, including how data sheets describe performance.
Domain 23: Intensive training for industrial practice
Setting up systems according to circuit diagrams and commissioning them. This is the practical capstone and explains why completing all hands-on labs is a stated requirement.
Domain 24: Fundamentals of proportional hydraulics
Proportional valves allow continuously variable control of flow or pressure rather than simple on/off switching. Expect conceptual questions on what makes proportional control different.
Worked Examples in the Exam Style
The following are original practice illustrations written for this guide, not recalled exam items. They show the kind of reasoning the domains call for.
Example 1: Force, pressure and area (Domain 5)
A double-acting cylinder has a piston area of 20 cm² on the extend side, and the rod occupies 4 cm² of that area. Supply pressure is 6 bar. Which stroke produces more force?
Worked answer: Using F = p × A, with 6 bar equal to 60 N/cm², extend force is 60 × 20 = 1,200 N. On retract, the effective area is 20 − 4 = 16 cm², so force is 60 × 16 = 960 N. The extend stroke produces more force because the rod reduces the retract-side area.
Example 2: Boyle's law (Domain 3)
Air at 1 bar absolute in a 10-liter volume is compressed isothermally to 2 liters. What is the new absolute pressure?
Worked answer: At constant temperature, p₁V₁ = p₂V₂. So 1 × 10 = p₂ × 2, giving p₂ = 5 bar absolute. Watch for questions that mix gauge and absolute pressure.
Example 3: Logic (Domain 13)
A press cylinder should extend only when two-hand buttons are both pressed. Which logic element applies, and which valve implements it?
Worked answer: This is an AND condition, implemented with a two-pressure valve, so the output appears only when both input signals are present. A shuttle valve would wrongly allow either button alone to trigger the press.
Key Takeaway
Write out every calculation with units. Most lost points in force, pressure and area problems come from unit slips or forgetting the rod area, not from misunderstanding the formula.
Scheduling the Domains Across Your Prep
You do not need a generic study system here. You need to sequence domains so that each builds on the last. This pneumatics-first layout assumes you are preparing for one branch at a time, which matches how the credentials are structured.
Foundations: Domains 1-5
- Safety, system layout, Pascal and Boyle
- Daily force/pressure/area drills
Valves and actuation: Domains 6-9
- Memorize 3/2 and 5/2 port functions
- Trace three circuits end to end
Control and logic: Domains 10-16
- Flow control, pressure control, AND/OR/NOT
- Limit switch and oscillation circuits
Hydraulics: Domains 18-24
- Symbols first, then principles, then measurement
- Finish with proportional hydraulics concepts
Simulation tools such as FluidSIM can help you design and troubleshoot circuits, but they are a practice aid, not established as required exam software, and they do not replace the required hands-on labs. For a full prep framework, see the FFPPH Study Guide, and when you are ready to test yourself, use the FFPPH practice tests.
Logistics, Passing Score and Cost Mechanics
Eligibility is tied to training, not just testing. Students need training from an actively NC3-certified instructor using required equipment, completion of all hands-on labs, and an exam score of at least 70%. Student recertification is not required. Proctoring and open-book or closed-book rules are set by the school and exam, so do not assume instructor-level rules apply to you. The details are in FFPPH Requirements and FFPPH Passing Score.
On cost, NC3 lists a student certification charge of US$0, but training tuition and institutional charges are separate. As one local example, Virginia Western's Mechatronics Fundamentals lists estimated Fluid Power tuition of US$1,497 for a one-week course, including online resources, lab equipment and the credentialing exam, with qualifying FastForward and G3 assistance reducing the listed student cost to US$499 and US$0 respectively. These are local course prices, not a national exam fee. See FFPPH Certification Cost for the breakdown.
Where These Skills Get Used
The domains map directly onto maintenance and troubleshooting work: reading schematics, diagnosing a sluggish cylinder, checking pressure, commissioning a hydraulic circuit. Employers in manufacturing, packaging, and plant maintenance routinely depend on these skills.
For context, the U.S. Bureau of Labor Statistics reports a May 2025 median annual wage of US$64,520 for industrial machinery mechanics. That figure describes the occupation, not a Festo certificate salary, a starting wage, or a measured certification premium, and no proven pay increase from this credential has been established. For deeper treatment, see FFPPH Salary Guide, FFPPH Jobs and Is the FFPPH Certification Worth It?
A note on comparisons: the International Fluid Power Society (IFPS) offers separate credentials such as Fluid Power Specialist and Hydraulic Specialist. Their syllabi, prerequisites and test rules are different from Festo/NC3, so do not mix preparation materials between them.
Frequently Asked Questions
No. They reproduce Festo preparation-curriculum topics in sequence. No official percentage weights were verified, so prepare for all 24 rather than relying on an invented breakdown.
Not necessarily. Pneumatics (Domains 1-17) and Hydraulics (Domains 18-24) are separate Level 1 credentials. School records, such as Virginia's, list each as its own 50-item test.
The stated requirement is at least 70%, alongside training by an NC3-certified instructor and completion of all hands-on labs. See the passing score guide for details.
Since weights are unverified, secure the foundations first: Pascal and Boyle, force/pressure/area calculations, and schematic symbols. These support nearly every other domain in both branches.
