SPECIFICATION FOR PLY WOOD TEA-CHESTPART II I BATTENS(Fourth Revision)

0. FOREWORD0.1 hisndian Standard (Part III) (Fourth Revision) was adopted by thIndian Standards Institution on 19 February 1974, after the draft finalizedby the Wood Products Sectional Committee had been approved by the CivEngineering Division Council.0.2 S : lo-1970* covers provisions relating to different components oa plywood tea-chest, namely, battens, plywood panels, metal fittings, etcBesides, it also covers provisions in respect of sizes and testing of assembledtea-chest. Since some of these aspects are the concern of different tradessuch as for plywood, battens, metal fittings and to assist the quality enforcement procedures it has been felt that, the fourth revision of IS : IO-1970*be published in parts. This part deals with battens for plywood tea-chestsOther parts dealing with plywood panels, metal fittings, etc, would bprepared in due course.

0.2.1 In addition to the requirements already covered under IS : lo-1970*,this standard specifies certain minimum strength requirements of thbattens as determined on full length finished battens.0.3 In the formulation of this standard due weightage has been given to thinternational co-ordination among the standards and practices prevailing idifferent countries in addition to relating it to the practices in the field ithis country.0.4 For the purpose of deciding whether a particular requirement of thistandard is complied with, the final value, observed or calculated, expressingthe result of a test or analysis, shall be rounded off in accordance withIS : 2-1960t. The number of significant places retained in the rounded ovalue should be the same as that of the specified value in this standard.1. SCOPE

5/17

IS : 10 (Par t I I I ) - 19742. TERMINOLOGY2.1 For the purpose of this standard, the definitions given in IS : 707-1968*and the following shall apply.

2.1.1 Batten - A rectangular cross-sectioned piece of timber used in thecorners of a tea-chest.

2.1.2 Checks- A separation of fibres along the grain which is confinedto one face of the batten.2.1.3 Insect Holes (Borer Holes) - A hole caused by the attack of woodboring insects and other organisms.2.1.4 Knot-A branch base or limb embedded in the batten duringthe natural growth of the tree.2.1.5 Split - A separation of fibres which extends from one face of thebatten to another and runs along the grain of the piece.2.1.6 War@ A deviation or distortion from a true plane of the surfaceof the batten due to stresses caused by uneven moisture content.

3. SPECIES OF TIMBER3.1 The battens shall be manufactured from any of the timbers listed inAppendix A, subject to certain species being treated in the manner describedtherein. The species of timber selected for the manufacture of battens shallhave strength properties as required under 7.

NOTE Only fir and spruce are*generally recommended for battena for tea-chests forexport purposa.4. DIMENSIONS AND TOLERANCES4.1 Dimensions

4.1.1 For all sizes of tea-chests (see IS : lo-1970t), except tea-chest .usedfor packing instant tea (see 4.1.2) the cross section of the battens shall be2.2 x2.0 cm subject to the tolerances given under 4.2. The length of a setof 12 battens required for assembling a tea-chest shall be governed by thefollowing :

a) Four pieces shall be of length = H-5.4 cmb) Four pieces shall be of length = W-l cmc) Four pieces shall be of length = L-l cmWhere L, W and H are the length, width and height of the tea-chestrespectively (see Fig. 1).

4.1.1.1 The dimensions of L, W and H, in that order, shall be governedby the overall dimensions, namely, length, width and height of the tea-chest,

4.1.2 The cross section of battens for tea-chest used for packing instant-shall be 2.6 x 2.6 cm. The length of a set of 12 battens shall be as follows :a) 4 pieces shall be of length = 78.3 cmb) 4 pieces shall be of length = 65.8 cmc) 4 pieces shall be of length = 35.2 cmT o l e r a n c e s - The following tolerances shall be allowed on the variousof the battens:

The inclinations of grain shall not exceed 1 in 15.5.1.1.1 If a batten with a permissible moisture content and graindeviation is tested on a surface plate, a deviation from straightness up to2.0 mm at the centre of the batten may be allowed.

5.1.1.2 Insect holes - Live insect holes shall not be permitted. Deadinsect holes may be permitted up to a maximum of 2 per batten provided theyare only pin holes (that is, maximum dia 2 mm).5.1.1.3 Live kn ots - Live knots up to a maximum of 6.5 mm in dia-meter may be permitted. However, such knots shall not be more than 3 inany batten and shall be away at least 50 mm from any end of the batten and5 mm from any edge.

5.1.2 Moisture content of battens shall be determined on small portionsapproximately 2.5 cm in length taken from mid length portion of each battenand of full cross section by the oven dry procedure given in IS : 170%1969*.It shall not exceed 15 percent. The moisture content may also be deter-mined by a calibrated moisture meter provided the same is measured at midlength position of the battens on the centre of one of the broad faces.5.1.3 In any one consignment, lots of battens sufficient for at least 100chests (or all the chests, if t h e lot is of a smaller quantity) shall be of the same

species.6. FINISHING6.1 All the battens shall be finished reasonably smooth. The battens fortop and bottom shall have the ends mitred across the narrow face (2.0 cm)whereas the corner.pieces shall have square ends. However, for tea-chestsused for packing htant tea, all battens may be finished with square ends.7.
