0. FOREWORD
0.1 This Indian Standard ( Part 1 ) 6 the Indian Standards Institution on 3
Fourth Revision ) was adopted by June lC83, after the draft finalized
by the Doors, Windows and Shutters Sectional Committee had been approved by the Civil Engineering Division Council.
0.2 This standard was first published in 1962 and subsequently revised in, 1966, 1973 and 1980. During this p’eriod the standard has undergone modification relating to grade of doors, species of timber, etc, and the sizes were rationalized.
0.3 Keeping in .view the advantages of modular co-ordination, Indian Standards specify the dimensions of componerits in modular units. In line with this, t+e dimensions of shutters w&e also specified in modular units. Hqwever, it was repeatedly brought to the notice of the Com- mittee that there, ‘was sufficient demand for sizes other than modular sizes and that the manufacturers were meeting such demands at present. This had led to a situation where shutters satisfying the other require- ments of.the standard, but not t were classified as not satisfyi ’ 2
requirements regarding the dimensions the requirements of the standard. This
situation also came in the w&y of satisfying :he consumer needs for other quality requirements by a third party inspection system. ,Therefore, with a view to encouraging production of timber shutters to the quality requirements specified in the standard, the Committee reviewed the relevant clauses of the Indian Standards +pd decided to relax the dimensional requirements in this fourth revision by permitting non- modular sizes in addition to the modular sizer specified in the standard at present. However, the relaxation has been made only in the height and ‘width, the thickness, remaining unchanged from the present pro- vision& This relaxation will be for a period of four years from the
3 ‘

publication of this standard and,it is intended that the manufacturers and consume& organization9 can gradually switch-over within this period to the modular sixes, which are the preferred sixes.
0.4 Routine tests with respect to performance of flush doors are covered in this standard: Suitable type tetts with respect to performance which will be useful for .manufacturers in evolving proper designs of flush doors are covered separately in IS : 4020-1967*.
0.5 For the purpose of deciding whether a particular requirement of this.standard is complied with, the final value, observed or calculated, expressing the result of a test shall be rounded off in accordance with IS : 2- 196Ot. The number of signi3cant places.retained in the rounded off value should be the same as that of the specified value in this standard.
1. SCOPE
1.1 This standard ( Part 1 ) lays down requirements regarding types, sixes, material, construction, workmanship and finish, and tests of cellular and hollow core wooden flush door shutters. with face panels of plywood or cross-band and face veneers.
2. TERlUl.NOLOGY
2.1 For the purpose of this standard, the definitions given in IS : kO428- 1983$ and IS : 707-19765 shall apply.
3. TYPES
9.1 Cellular or hollow core flush door. shutters may be of the decorative type or non-decorative ( paintable ) type. The nature of construction of these shutters shall, therefore, be specified based on the type and cons- truction of core as given in Table 1.

7.1 Locks - Shutters shall be shop-prepared for taking mortice locks or latches as may be ordered. Shop preparing thedoor, with morticed holes for lock fixing shall be done only when desired by the purchaser. Where the purchaser so deiires, suitable blocks of wood may be provided for fixing the hardware. In the absence of specific requirements,. block shall preferably correspond to the maximum size of lock covered in IS : ,220:). 1976*.
8. WORKMANSHIP AND FRQS=
8.,l All the four edges of the door shutter shall be square. The shutter shall be free from twist or_ warp in its plane.
8.2 Both faces of door shutter shall be ‘sanded to a smooth even texture. If required by the purchaser, all surfaces of shutters which are .required to be painted shall be covered evenly by brush ,painting with a priming coat of primer as specified-in IS : 2338 ( Part 1 )-1967t. In the case of shutters to he polished or varnished; a priming coat of suitable polish or varnish shall be given before delivery. However, only unpainted doors shall be subjected to the tests mentioned under 9.
8.3 Workmanship and finish of the face panels shall be in conformity with those specified in IS : 303-1975: for commercial type and IS : 1328- 19705 for decorative type.
9. TESTS
9.1 Ena hnmermion Temt - Door shutters shall be tested for resistance of their base to immersion in water as follows:
The door shutter shall be immersed vertically to a height of 30 cm in water at room temperature in 27 f 2°C and relative humidity of 65 f 5 percent for 24 hours and then allowed to dry for 24 hours. The cycle shall be repeated eight times. There shall be no delamination at the end of the test.

9.2 Knife Test - The face panel, when tested in accordance wuh. Appendix F of IS : 1659-1979*, shall pass the test.
9.3 Adhesion Teat -,The flush door shall he tested for adhesion in accordance with 9.3.1.
9.3.1 Two square sections, 150 mm. x 150 mm shall be cut from the corners of the doer. These corner sections, as cut from the door, shall be immersed in boiling water at 100°C for four hours, then dried at.27 .f 2°C and relatiqe,#ntmidity of 65 f 5 percent for 24 hours. At the end of the drying period the samples shall be examined for delami- nation. Glue lines in all the four exposed edges of the plywood on both faces of a specimen and the glue lines between the plywood faces and the stile and rail shall be examined for delamination.
9.3.1.1 A specimen shall be considered to have pasred the test if no delamination has occurred in the glue lines in the plywood and if no single delamination more than 50 mm in length and more than 3 mm in depth has occurred in the assembly glue lines between the plywood faces and ,the stile and rail. Delamination at the corner shall be measured continuously around the corner. Delamination at a knot, hole, pitch pocket, worm hole, or other permissible‘ wood defects shall not be considered in assessing the sample., A door shall be deemed to have passed this test if both the specimens tested pass the test.
9.4 Type Tests - The manufacturer may also have the performance test of the flush door tested by the type tests covered in IS : 4020-1967t. The type tests shall only apply to the specific design of the flush door and need not be applied as routine tests.
10. SAMPLING AND CRITERIA FOR CONFORMITY
10.1 The sampling and criteria for conformity for flush door shutters shall be as.given in Appendix B.
11. MARKING
11.1 Each shutter should be legibly and indelibly marked on any of its edges with the following information:
a)- Name of the manufacturer or trade-mark, if any;
b) Abbreviation indicating the nature of construction of the shutter ( set 3.1 );

11.1.1 The shutter may also be marked with the Standard Mark
IS t 2191( Part 1) - 1983
NOTE - The use of the Standard Mark is governed by the provisions of the Bureau of Indian Standards Act, 1986 and the Rules and Regulations made there- under. The Standard Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well defined system of inspection, testing and quality control which is devised and supervised by BIS and operated by the producer. Standard marked products are also continuously checked by BIS for conformity to that standard as a further safeguard. Details of conditions under which a Jicence for rho use of the Standard Mark may be granted to manufacturers or producers may be obtained from the Bureau of Indian Standards.
