1According to EN 988, what specific alloying elements are added to high-grade zinc to produce modern architectural titanzink (titanium-zinc)?
A.Titanium (0.06–0.20%) and copper (0.08–1.0%)
B.Aluminium (1.5–3.0%) and magnesium (0.5–1.0%)
C.Lead (2.0–4.0%) and tin (1.0–2.0%)
D.Nickel (0.5–1.5%) and silicon (0.2–0.8%)
Explanation: Modern titanzink conforming to EN 988 is produced from primary refined zinc (99.995% purity) alloyed with precise micro-additions of titanium (0.06–0.20%) and copper (0.08–1.0%). Titanium increases creep resistance and reduces thermal elongation, while copper increases tensile strength and improves workability during folding.
2What is the standard nominal finished upstand height of a conventional stående fals (standing seam) on roofing installations in Denmark?
A.15 mm
B.38 mm
C.25 mm
D.50 mm
Explanation: In Scandinavian and European sheet metal trade standards, the standard finished height of a double standing seam (dobbelt stående fals) is 25 mm. This requires folding an underlap upstand of 35 mm and an overlap upstand of 45 mm prior to closing the seam.
3What is the recognized minimum roof pitch for installing a standard dobbelt stående fals without supplementary seam sealing tape (falsolie or tætningsbånd)?
A.3° (approx. 5%)
B.7° (approx. 12%)
C.15° (approx. 27%)
D.25° (approx. 47%)
Explanation: Under Danish roofing craft guidelines, a standard double standing seam is rainproof without continuous seam sealant down to a roof pitch of 7° (approx. 12%). For lower slopes between 3° and 7°, continuous sealing tapes or sealing gels must be inserted into the seam to resist standing water and back pressure.
4What chemical compound forms the natural, insoluble protective patina on bright titanium-zinc when exposed to atmospheric moisture and atmospheric carbon dioxide?
A.Zinc chloride (zinkklorid)
B.Zinc sulfate (zinksulfat)
C.Zinc nitrate (zinknitrat)
D.Basic zinc carbonate (zinkhydroxycarbonat)
Explanation: When exposed to the atmosphere, bright zinc first reacts with oxygen to form zinc oxide, then with water to form zinc hydroxide, and finally with atmospheric carbon dioxide (CO2) to form an insoluble, tightly adhering layer of basic zinc carbonate [Zn5(CO3)2(OH)6]. This self-healing layer protects the metal against progressive atmospheric corrosion.
5Why must titanium-zinc sheets never be mechanically folded or shaped on the workshop brake when the metal temperature is below +7°C without gentle preheating?
A.Zinc exhibits cold-shortness (kørsprødhed) and will crack or micro-fracture along the bend line
B.The flux will not adhere to the surface during later soldering operations
C.The copper alloying elements migrate to the surface and cause instant discolouration
D.The metal expands excessively when heated later, tearing the holding clips
Explanation: Titanium-zinc has a hexagonal close-packed crystal structure that exhibits cold-shortness or brittleness at low temperatures. Bending below +7°C induces severe tensile micro-cracks along the deformation axis, leading to premature seam failure. If work must proceed in cold weather, the folding area must be gently warmed with a hot-air gun.
6Which location is generally most suitable for a vinkelfals (single lock angle seam), subject to the selected metal system's approved pitch and exposure limits?
A.On low-pitch roofs between 3° and 7° with standing water risks
B.In concealed valley gutters carrying high volumetric water runoff
C.On vertical facade cladding or sufficiently steep roof sections where the system supplier permits it
D.Underneath chimney sadler where water pools
Explanation: A vinkelfals has less resistance to backed-up or wind-driven water than a double standing seam, so it is best suited to facades and steep, freely draining surfaces. The minimum permitted pitch is system-, material-, and exposure-dependent; the project specification and supplier instructions control rather than a universal 25° or 35° figure.
7What is the linear coefficient of thermal expansion (α) of architectural titanium-zinc in the longitudinal rolling direction?
A.Approx. 0.012 mm/(m·°C) (1.2 × 10⁻⁵ K⁻¹)
B.Approx. 0.022 mm/(m·°C) (2.2 × 10⁻⁵ K⁻¹)
C.Approx. 0.035 mm/(m·°C) (3.5 × 10⁻⁵ K⁻¹)
D.Approx. 0.005 mm/(m·°C) (0.5 × 10⁻⁵ K⁻¹)
Explanation: The linear thermal expansion coefficient for titanium-zinc in the rolling direction is approximately 0.022 mm per meter per degree Celsius (2.2 mm per meter over a 100°C temperature swing). Across the rolling direction, it is slightly lower (approx. 0.017 mm/(m·°C)), but 0.022 is the standard value used for longitudinal expansion calculations.
8What is the critical mechanical difference in function between faste hafter (fixed clips) and glidehafter (sliding clips) in standing seam roofing?
A.Faste hafter are used exclusively on facades, while glidehafter are only permitted on flat eaves
B.Glidehafter are soldered permanently to the underside of the sheet, while faste hafter are mechanically folded
C.Faste hafter are made of plastic, while glidehafter are made of stainless steel
D.Glidehafter restrain the seam against wind uplift while allowing free longitudinal thermal expansion, whereas faste hafter anchor the tray rigidly at one location
Explanation: Faste hafter (fixed clips) anchor the roofing tray firmly to the timber deck at a defined position to prevent the tray from sliding downhill under gravity. Glidehafter (sliding clips) consist of a two-piece assembly with a sliding tab that holds the seam down against wind uplift forces while permitting the tray to expand and contract freely along its length.
9A continuous titanium-zinc roof tray (skare) has a length of 9.0 meters. It is installed at an ambient temperature of 10°C, and the maximum anticipated summer surface temperature is 70°C (ΔT = 60°C). Using α = 0.022 mm/(m·°C), what is the calculated thermal elongation (ΔL)?
A.11.88 mm (approx. 11.9 mm)
B.5.94 mm (approx. 5.9 mm)
C.15.84 mm (approx. 15.8 mm)
D.23.76 mm (approx. 23.8 mm)
Explanation: Thermal expansion is ΔL = L × α × ΔT. Here, ΔL = 9.0 m × 0.022 mm/(m·°C) × 60°C = 11.88 mm. The clip and joint design must accommodate that calculated movement in the relevant direction.
10A continuous copper valley gutter (skotrende) has an unbroken length of 12.0 meters. If the temperature fluctuates from a winter minimum of -15°C to a summer peak of +65°C (ΔT = 80°C), what is the total thermal expansion movement given copper's expansion coefficient α = 0.017 mm/(m·°C)?
A.12.24 mm (approx. 12.2 mm)
B.21.12 mm (approx. 21.1 mm)
C.16.32 mm (approx. 16.3 mm)
D.8.16 mm (approx. 8.2 mm)
Explanation: Applying the formula ΔL = L × α × ΔT: L = 12.0 m, α = 0.017 mm/(m·°C), and ΔT = 65 - (-15) = 80°C. Calculating: ΔL = 12.0 × 0.017 × 80 = 16.32 mm. The detailing of the gutter ends and cleats must accommodate over 16 mm of expansion without buckling.

About the Blikkenslagersvendeprøven Exam

Blikkenslager og VVS Svendeprøve is the statutory journeyman examination completing the 4-year sheet metal and roofing specialization of Denmark's VVS-energiuddannelse (BEK nr. 142/2026). Candidates demonstrate mastery of sheet metal fabrication (zinc, copper, aluminium), seam forming (stående fals, dobbeltfals), roof and dormer flashings, gutter sizing under DS/EN 12056-3, soft soldering, pattern development, and strict roof safety regulations. This study bank prepares apprentices for theoretical calculations, standards compliance, and technical decision-making assessed by the skuemestre.

Both projects conclude with 20-minute oral examinations before the assessment team.

Time Limit

H3 project: 18 hours over 3 days plus a 20-minute oral. H4 written paper: 2 hours. H4 flashing project: 45 hours over 8 days plus a 20-minute oral; the H4 period is 2 weeks including graduation and cleanup.

Passing Score

Grade 02 or higher on the Danish 7-point grading scale (7-trinsskalaen) in each independent sub-examination (delprøve).

Exam Fee

No candidate-paid fee or current 2026 employer charge was published in the reviewed EVU material; confirm any company charge with EVU. (Approved vocational school with Det Faglige Fællesudvalg for VVS-energiuddannelsen (EVU))
