PrefaceThis Nepal Standard was prepared during 1993 as part of a project to prepare a draft National Building
Code for Nepal.
In 1988 the Ministry of Housing and Physical Planning (MHPP), conscious of the growing needs of
Nepal's urban and shelter sectors, requested technical assistance from the United Nations Development
Programme and their executing agency, United Nations Centre for Human Settlements (UNCHS).
A programme of Policy and Technical Support was set up within the Ministry (UNDP Project
NEP/88/054) and a number of activities have been undertaken within this framework.
The 1988 earthquake in Nepal, and the resulting deaths and damage to both housing and schools, again
drew attention to the need for changes and improvement in current building construction and design
methods.
Until now, Nepal has not had any regulations or documents of its own setting out either requirements orgood practice for achieving satisfactory strength in buildings.
In late 1991 the MHPP and UNCHS requested proposals for the development of such regulations anddocuments from international organisations in response to terms of reference prepared by a panel ofexperts.
This document has been prepared by the subcontractor's team working within the Department of
Building, the team including members of the Department and the MHPP. As part of the proposedmanagement and implementation strategy, it has been prepared so as to conform with the general
presentation requirements of the Nepal Bureau of Standards and Metrology.
The subproject has been undertaken under the aegis of an Advisory Panel to the MHPP.
The Advisory Panel consisted of :Mr. UB Malla, Joint Secretary, MHPP
Director General, Department of Building(Mr. LR Upadhyay)
Mr. AR Pant, Under Secretary, MHPP
Director General, Department of Mines & Geology(Mr. PL Shrestha)

Foreword
This Standard deals with the requisite quality and effectiveness of construction materials
used mainly in the building construction. It also deals with the storage of materials wherestorage has relevance to strength.
0.1

NBC101V2.RV8

Since the quality requirements and test methods used to determine the quality are
enumerated in the relevant materials standards, this standards provide a list of Nepal
Standards (NS) for key materials used in the building construction. A list of related
Indian Standards (IS) has been included for those materials for which Nepal
Standards (NS) do not exist as yet. When NS or IS prepare Standards for othermaterials having a bearing on the strength characteristics of the buildings, or revised
version of the existing Standard, these shall be deemed to be the requirement of thisStandard. If it exists, the requirements of NS will govern and be mandatory unlessthe designer has based his design on a standard other than NS. The use of
appropriate, adopted or new materials is encouraged, provided these materials havebeen proven to meet their intended purposes.

1

Scope
The minimum requirements of building materials for buildings complying with the National
Building Code are set forth in this part of Standard. Criteria for accepting the use of
appropriate and adopted new materials are also outlined.

2

Interpretation
2.1

GeneralIn this Standard the word "shall" indicates a requirement that is to be adopted in order
to comply with the Standard, while the word "should" indicates recommended
practice.
Commentary clauses are prefaced by the letter C and the number of the appropriateclause subject to comment.

3

Materials
The use of materials confirming to NS or IS or any other approved standards agency shalldeem to have satisfied the requirements of this Standard. A list of such Nepal Standards andIndian Standards appear in section 9 below.

4

Appropriate, Adopted or New Materials
Any appropriate, adopted or new materials that are not covered by the provision of thisStandard may also be used in buildings requiring National Building code compliance,
provided that these materials are equivalent, or better in quality, strength, effectiveness, fire
resistance, durability, safety, maintenance and compatibility. Prior to the use of suchmaterials, it shall be the responsibility of the building owner, or the authorised
representative of the building owner, to obtain proof of equivalency.

5

Recycled / Used Materials
If recycled / used materials meet the requirements of the Standard, they may also be used.

6

Storage of the Materials
All building materials shall be stored in such a manner that no deterioration or loss or
impairment of their structural and other inherent properties takes place.

NBC105V2.RV5

10 May 1994

7

Transportation of Materials
All building materials shall be transported so as not to impair their inherent properties.

8

Methods of Test
The testing of materials necessary to fulfill the requirements of this Standard shall be
carried out in accordance with the procedures laid down by NS. Where a NS procedure is
not available, the testing shall conform to the procedures stipulated by IS or any otherauthority of similar stature. The test are to be carried out by appropriately-competentpersons in a suitable laboratory. The list of Nepal Standards and Indian Standards formaterials, which appear in the following section, also stipulate the procedures for testing.

9

List of Standards
Table 9.1 lists those Standards which are mandatory as minimum requirements for buildings
designed to comply with other Nepal Standards for Engineered design.
The latest version of a Standard shall be used.
