Method Statement for Fischer Hydrajaws Pull Off Tester OBJECTIVE The purpose of site tests may be either: a) Investigative Test (Mock Up) - To establish the suitability of fixing and/or admissible resistance in a particular base material. This is provided as part of the product submission for consultant approval. The test is usually witnessed by the consulting engineers, owners and contractors. b) Proof Test - To confirm the Manufacturer's Design Resistance. "Manufacturer's Design Resistance" means the resistance designed by the Manufacturer for that type and size of fixing in the base material with known concrete strength, taking account of any spacing and / or edge distances reduction factors. This is usually performed on request by consultants or their representative as well as the contractor. c) Validation Test - To validate installation / adequacy of the installation of fixings. This is usually proposed by the consultants to validate the quality of work by installers or contractors. GUIDELINES 1. Pull-out test result should meet the minimum required Design Load. 2. For anchors, Proof Resistance of 1.4 times the Recommended Resistance (Design Resistance with reference to Fischer Handbook International) should be used as a guideline. If there is anchor design calculation done by Fischer, the Design Resistance should be used. For testing of non-Fischer anchor / cast-in channel, client is to provide the references test load value. 3. For Anchor, Proof Resistance of 1.4 times the Recommended Resistance (Design Resistance with reference to Fischer Handbook International) should be used as a

guideline, provided that it does not exceed the ultimate service limit (95% of yield strength of steel). 4. Thread engagement between fixing and coupler should be adequate to take the applied load and for Ultimate Resistance Testing should be at least 1.5 x d, where d = nominal diameter of the thread under test.

5. The load-measuring gauge should be accurate to within 10% of the readings. This equipment should be recalibrated annually / bi-annually, by a laboratory with load measuring equipment whose calibration is traceable to national standards such as Sirim. 6. The consulting engineer requesting the tests should decide the number of tests required, however, the following guidelines may be used as reference.

1. For Ultimate Resistance and derivation of Recommended Resistance in establishing suitability of the fixing in a particular base material at least 3-5 tests should be carried out. 2. For investigation test (mock up) and validation test, number of test is dependent on consultants / contractors’ requirements.

GENERAL TESTING PROCEDURE General guideline of operating Fischer Hydrajaws Pull Off Tester may be different depending on site condition & type of anchor to be tested. Detail operating instruction is available under operation manual (upon request). 1.

Client to identify test points onsite.

2.

Surface of the surrounding anchor to be tested should be even and clear of obstructions to allow fixing of load spreading bridge

3.

Tighten up the specific size bolt adapter based on size of anchor to be tested.

4.

Setting up Fischer Hydrajaws Pull Off Tester on the anchor and ensure load spreading bridge is in leveled condition based on bubble level by manually adjust the adjustable legs.

5.

Ensure all locking nuts on load spreading bridge had been tighten accordingly.

6.

Install the load gauge meter.

7.

Before the test, adjust the red pointer on the load gauge meter reading to zero.

8.

Increase the loading by manually turning the load screw clockwise gradually until the required test load is attained. Hold this load and observe any falling back of the gauge pointer which would indicate movement and possible failure of the fastener. Record the satisfactory load. The red pointer indicate the highest load achieved.

9.

Release the load on the fastener by turning the operation handle anti-clockwise and allowing the test jaw to return to the original position.

10. Maximum pull out load capacity dependent on model and are listed below: a. Model 2000: 25kN maximum capacity b. Model 2050: 50kN maximum capacity

TEST REPORT 1.

After each test, a soft copy test report is produced to record the details. Soft copy report will email to customer directly. Hard copy test report will only be prepared upon request with additional charges applied. The original will be kept in Defix’s office for record purposes.

2.

Test report will include testing site details, personnel involvement, product information, applications details, method and procedure of test, equipment info, reports, and calibration certificates.

3.

Test report lead time is 7 working days from date of testing
