MYANMAR NATIONAL BUILDING CODEPART 6: BUILDING MATERIALS6.1 SCOPEThis Part of the Code covers the requirements of building materials and components, and criteriafor accepting of new or alternative buildings materials and components.6.2 MATERIALSEvery material used in fulfilment of the requirements of this Part, unless otherwise specified inthe Code or Duly Approved, shall conform to the relevant ASTM or Indian Standards. A list ofthe „accepted standards‟ is given at the end of this Part of Code.Remark : Building Materials included in this Myanmar National Building Code are temporarilyreferring to the ASTM and IS. Ministry of Construction and Ministry of Education are collaborating in the preparationof the National Standards and Specifications for Building Materials. Before the National Level Standards and Specifications are officially established, allBuilding Materials should be conformed to relevant reference to the ASTM and IS.6.3 NEW OR ALTERNATIVE MATERIALS6.3.1The provisions of this Part are not intended to prevent the use of any material notspecifically prescribed under 6.2. Any such material may require the approval of the ConcernedAuthority or a Committee appointed by the Authority, provided it is well established that thematerial is satisfactorily acceptable for the purpose it is intended. The Authority or theCommittee concerned shall take into account the following parameters, with respect to the use ofnew or alternative building materials.The prerequisite of the specified material, in addition to meeting those in the standardson its usage, shall also take into account their suitability in different geo-climaticcondition.a) General appearance;b) Dimension and dimensional stability;c) Structural stability including strength properties;

d) Fire resistant ;e) Durability;f) Thermal properties;g) Mechanical properties;h) Acoustical properties;i) Optical properties;j) Biological effect;k) Environmental aspects;l) Working condition ;m) Ease of handling; andn) Consistency and workability.For establishing the performance of the Material/component, laboratory/field tests, and fieldtrials, are required. The study of historical data is also recommended.6.3.2 Approval in writing by the Authority or the Concerned Committee appointed for thepurpose of evaluating the approval of material shall be obtained by the owner of the material orhis agent before any new, alternative or equivalent material is put to use. The Authority or TheCommittee appointed by them shall base such approval on the principle set in paragraph 6.3.1and shall require that tests be made (see 7.1) or sufficient evidence or proof be submitted. Allexpenses incurred shall be duly borne by the owner or his agent.6.4 STORAGE OF MATERIALSAll building materials shall be stored on the construction site with all the necessary measurestaken to prevent deterioration, the loss or impairment of their structural or other essentialproperties. (See Part -7 Construction Practices and Safety)6.5 METHODS OF TEST6.5.1 Every test of material required in this Part or by the Authority shall be carried out inaccordance with the ASTM Standard or Indian Standard method of test. In case where testingfacilities or methods of tests for either the ASTM or Indian Standards are not available, thesame shall conform to the methods of tests approved by the Authority. Laboratory tests shall beconducted by recognized laboratories acceptable to the Authority.6.5.2 The manufacturer/supplier shall duly testify that materials conform to the requirements ofthe specifications and if requested shall produce a certificate to this effect either to the purchaser

or his representative. When such test certificate is not available, the specimen of the materialshall be subjected to all the required tests.Following are the Myanmar Standards for various building materials and components, to becomplied with in fulfilment of the requirements of the Code.
