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 295 x 105mm
• Weight: 2.7kg

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.
5. The recording strip is used as a test document.
6. Mean rebound value R may be visually estimated.
