to BS1881, EN12504 part 2:2001

• Measuring range 10 to 70 N/mm2 compressive strength.
• Handling and dimensions as for types N and Nr, but with a three times smaller impact energy.
• These types are used for testing thin walled (< 100 mm) or small components but also cast stone components sensitive to impact.
• Supplied in a carrying case including a grinding stone and operating instructions.
• Case Dimensions: 325 x 125 x 140mm
• Weight: 1.4kg

Test Procedure

1. (Similar for all types)
2. Smooth test area with a grinding stone.
3. Perform test series of at least ten test impacts.
4. The compressive strength of the concrete is read from a conversion chart.
