Construction products in the Hong Kong market requires the Hong Kong HOKLAS qualification to issue the corresponding report to prove that the fire resistance performance of its products meet the requirements. Guangdong, Hong Kong-Macao and the Greater Bay Area have provided strong support to enter the Hong Kong construction market and even the global market. Smart professional provides Hong Kong HOKLAS qualification BS 476 fire resistance test, specific please consult Nanjing Smart company +86 25-8658 3475.
HOKLAS The Hong Kong Laboratory Accreditation Program
HongKong Laboratory Accreditation Scheme (HOKLAS), similar to the mainland CNAS certification. The laboratory has obtained the HOKLAS accreditation qualification, proving that the laboratory personnel, machine, material, method, ring, test after the accreditation, recognized the ability of the laboratory to conduct specific tests.
HOKLAS Qualification fire resistance standard
BS 476 Part 20 Fire resistance tests-general requirements
BS 476 Part 21 Fire resistance test foe loadbearing
BS 476 Part 22 Fire resistance test foe non-loadbearing
BS 476 Part 4 Nor-combustibility test for building material
BS 476 Part 6 Fire propagation for products
BS 476 Part 7 The Classification of the surface spread of flame of products

EN 1634-1:2015 Fire resistance test foe non-loadbearing
HOKLAS Qualification BS 476 Part 7 test
BS 476 Part 7: Fire tests on building materials and structures-Part 7 method of test to determine the classification of the surface spread of flame of products.
BS 476 Part 7 Scope of application-wall material exposed surface, insulation material exposed surface, ceiling material exposed surface, etc.
BS 476 Part 7 Test method
BS 476 Part 7 Determine the lateral extension of the sample surface and determine the combustion grade based on the speed and extension length, specify the test method for measuring the lateral spread of the flame on the sample surface placed in the vertical direction under radiation exposure conditions, and determine the combustion grade based on the flame spread speed and spread length. It is mainly used for measuring the flame extension performance of the exposed surface of the wall and ceiling.
BS 476 Part 7 Fire rating assessment Class 1-Class 4
BS476 Part 7 Class 1:1.5 min product flame surface extension shall not exceed 165mm; 10 min product flame surface extension not exceed 165mm.
BS476 Part 7 Class 2:1.5 min product flame surface shall not exceed 215mm; 10 min product flame surface shall not exceed 455mm.
BS476 Part 7 Class 3:1.5 min product flame surface extension shall not exceed 265mm; 10 min product flame surface extension shall not exceed 710mm.
BS476 Part 7 Class 4: Beyond the BS476-7 class 3 requirement limit
