FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the FootwearSectional Committee had been approved by the Chemical Division Council

This standard has been prepared basing its requirements on the lasts known in the trade as last No. 5338. DefenceDepartment adopted two models that is 9150 for boots (IS 5520:1969 ‘Specification for wooden lasts for heavy-duty boots’ is already adopted) and 5338 for shoes.

The footwear including heavy duty boots as well as various typ,w of shoes have been in use in Defence services forthe last number of decades. The sizes and length of the lasts were worked out in 1946 and since then footwear arebeing manufactured and supplied to Defence as per the length/other dimensions of the lasts then decided. Similaris the case with mining and heavy industry. Since adoption of various Indian Standard Specifications, there hasbeen no incident of complaint from the users with respect to the length of lasts on size stick.

Since boots and shoes are to be worn by the same individuals in the forces or in industry, specification for bothlasts 9150 and 5338 ale kept very similar except in case of minor deviation/adjustment made in case of 5338 lastthan 9150 last because of two different characteristics of footwear. The deviations are made at instep girthmeasurement, width of ball, width at heel, toe depth. Length of lasts for both Defence services and industryadopted the medium to broad toe last where 4.0 mm allowance over the standard length has been given forfaci Iitating comfort to users.

Since the direct vulcanization and injection moulding process have come into vogue, the system of combiningtwo/three fittings or[ one common insole has become very economical and rational. Considerable amount ofsaving in ‘tooling cost’ comes from using disc (pistons) and particularly side moulds, needed for this process; onlyseparate metal (moulding) feet for two/three fittings are required. Even though fitting characteristics of footwearmade through this system have been found satisfactory in some countries, the Committee decided not to prescribethis system in this standard at present. Three fittings are small, medium and large/wide/broad.

The composition of the Committee responsible for formulation of this standard is given in Annex C.

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 or analysis, shall be rounded off in accordance withIS 2: 1960 ‘Rules for rounding off numerical values (revise~’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

For the purpose of this standard, definitions given inIS 2050 shall apply.

4 REQUIREMENTS

4.1 MateriaJs

Materials for components (metal parts and others)consumable items required in manufacturing of shoelasts shall be similar as specified inIS4512.

4.2 Construction and Finish

Construction and finish shall be similar to the hingedlasts specified in IS 4512.

4.3 Design Detail

4.3.1 Insole Draft

The size 8 medium insole of lasts shall be as given inFig. 1. Other sizes and fittings shall be graded asindicated in Fig. 1. The details for the designing on theinsole of last shall be as given in Annex A.

NOTE—When considering the use of a common insole shape fortwo/three fittings for the moulded process of manufacture, severalfactors shall be taken into account:

@

b)

c)

A size 8 model last intermediate amongst three fittings suchas “S”, “M & “L” fittings with ajoint (ball) girth of248 mmshould be produced to give a S/hUL bottom pattern for thesethree fittings should have common moulds based on thisbottom pattern. S/M/L models should be made to give thedesired joint (ball) girths on the S/M/L bottom pattern bythe adjustment of the wood above the Insole feather line.

With one set of moulds covering three fittings, seperatemetal (moulding) feet for the three fittings may be used.The side moulds and sole mould only should be commonto the three fittings.

The initial last itself, when modelled, should have anadequate amount of “overhang” around the sides. Thisfeature facilitates the subsequent modelling of the otherfittings by the addition or subtraction of “top wood” and“side wood (see Fig, 2).

6 PACKING

6.1 Lasts shall be packed in boxes made of woodenplanks in conformity to the requirements prescribedin 6.1.1 and 6.1.2.

6.1.1 Boxes shall be lined with wrapping paper(waterproof) and layer of soft, dry paper or woodshmings along the bottom and the sides. The lasts shallbe packed tightly in rows, in such a way that metallicparts of the lasts come opposite to one another. Thespace between individual lasts shall be filled with paperor dry shavings. On the lasts packed in this way asecond layer of dry shavings or paper shall be spreadand in the same order a second row shall be packed. In

this way packing shall be continued fiuther till the boxis filled with lasts up to the upper edges. The top rowof lasts shall be covered with a layer of (by shavings orby wrapping paper.

6.1.2 Nails, fixing the cover lid, shall be correctlydriven in and shall not come out from the boards on theinner or outer surface of the box.

7 SAMPLING AND CRITERIA FORCONFORMITY

For the purpose of ascertaining the conformity of thelasts for shoes to this specitlcation, the scale of sampling

and criteria for conformity shall be as given in Annex B.

IS 15251:2002

8 TEST METHODS

Visual characteristics shall be checked in accordancewith model or ordered specimen.

8.1 Dimensional Characteristics

8.1.1 Checkup of lasts shall relate to the followingdimensions, measurements and various control patternsand gauges.

8.1.2 Determine the length of the lasts by size-stick;the proportions for the contiguous sizes is based on thegiven standard length for each heel height.

8.1.3 To ensure that the longitudinal and transversesections, as well as heel parts and bottom shape of anysize in a set of lasts agree with the specifications forshape and measurements, use graded insole patternsand various graded control profiles including back curveof the heel, toe profile for the entire size range.

NOTE-The patterns for insole and profile shall be cut to themaster or model size, from which remaining sizes shall begraded. It does give length, shape, width of the forepart andseat, and to this extent it is suitable for testing the lasts. Gradeswe Iixed arbitrarily and adopted by custom in the last industry,

8.1.4 On superimposition, the profile pattern of thelongitudinal bottom section (generally called ‘BottomProfi Ie’) shall coincide with the axis of the last alongwith the contour of the heel back curve.

8.1.5 On superimposition, the profile section of thelongitudinal toe section (generally called ‘Toe Profile’)shall coincide with the longitudinal axis of the body ofthe last in its upper forepart.

8.1.6 Carry out measurement of the last by standardlast measuring tape (a tape of non-variable dimensionswith fine metallic wire inside) the width of the tapeshall not be more that 10 mm.

8.1.7 During measurement of the joint and instep girth,lay the measuring tape on the last in such away that themeasuring edge of the tape fits closely and lies flat onthe last along the line of measurement.

8.1.8 During measurement of instep girth of the lasts,the measuring edge of the tape of the comb shall comein contact with the marked point. Near the bottom, thetape shall settle in the most concave part of the last insuch a manner as to give during this measurement ofthe last the smallest size.

8.1.9 Determine, the location of the joint measurementsby the model markers.

NOTE—It is impossible to prescribe a fixed standard forlocation of the joint measurements. The difficulty of uniformlocation is due to the curved surfaces and varying shapes oflasts. This problem of specifying the exact location of thejoint girth has been disputed with the last making and footwearindustry since early cratt days and remains unsolved. Variousforms of apparatus for location of joint and instep have beenmade but they are not in general use,

8.1.10 An approximate position for location of theball and instep girth measurement in insole pattern isshown in Fig. 3. This system requires little skill andmay be performed very easily without the help of anyapparatus and as such may be considered as standardpractice under the existing conditions.

NOTE—Although the joint girth measurement is takendiagonally in a transverse direction, but makers of lasts takethis measurement at arbitrary points to enable them to placethe measuring tape flat to the wood of the last. Generally thistakes in either the inside or outside joint, but never both.

8.1.11 Following the system described above,check the correctness of position of pin-points in thismanner; the bottom of the last, the insole, checked bymarked lines is superimposed, so that, starting fromthe toe part, it coincides all over with the bottom of thelast.

8.1.12 Pin-points at the joints (inside and outside) shallbe exactly located on the last at the ends of lines abovethe contour (feather edge) of the lasts at a distance of10 mm.

8.1.13 Correctness of the position of the pin-pointlocated on the body of the last at the base of the instep(along with centre line of the last) is checked either bythe measuring tape with the help of two pin-points of

/

the joints for measurement of the ball girth; or b>thelongitudinal front profile which with the mark point isputon the last andthecoincidence of thepin-pointonthe last with the point of the profile is observed.

8.1.14 Forthedetermination of thecorrectness of theposition of the pin-point for measurement of instep girthon the cone of the last the following method isrecommended.

8.1.15 This position isrepresented onthelast, alongthe middle of the cone, at a distance of 60 mm abovethe ball joint pin-point which is located at the base ofthe instep (cone) (see Fig. 3).

8.1.16 To ascertain the girth of the instep the tape shalllie flat and close to the last on the selected points.

NOTE—Like the joint measurement the instep measurementmay not also be located exactly by rule. Half standard lengthof the last (excluding the difference between the length of theinsole and the foot), on an imaginary line through the lengthmay be given as the approximate position. The largest girthat that point probably answers the purpose best,

8.1.17 Check-up of the Insole Pattern of Medium Size

[n order to check the basic dimensions of the insole, itis necessary to determine the position of points ofmeasurement.

Detertnine position of measurement by a special patternor template, the construction of which is given inFig. 4 and Annex A.

Test before hand carefully graded patterns of insole,profile templates of longitudinal and transversesections, used for check-up for the lasts.

NOTE—The actual or stick-length of last may vary from thestandard length of insole pattern as it frequently does. Theinsole length shall be always (2-3) shorter than the stick-lengthby virtue of the back curve protruding behind it. The acceptedstick-length of a last is the distance from the centre of thecurve at the back to the extreme tip of the toe. The actual

size-stick length is not to be used to denote the foot fittinglength ofa last. For any given shoe or last size. the foot shallbe shorterthan the insole by at least 10mm when measurementis taken in a sitting position.

8.1.18 Check the height of the last and the dimensionsof the tube by callipers.

8.1.19 Measure height of quarter pin mark or vampmark by tape or by a gauge.

8.2 Measurement of Heel Height

Place the last on a level surface. Raise the seat of thelast until the tread line touches the level surface. Thenmeasure the heel height from the seat position to thelevel surface. Take care that the seat of the last restsatmost parallel to the ground,

For all sizes and fittings, the heights of the heel of thelast shall be 30 mm and the toe spring shall be 20 mm.

8.3 Moisture Content

To determine the moisture content, sample pairs shallbe drawn at random from those already tested (seeB-2.1 .3.1) in accordance withCO14 and 6 of Table 3.From the middle of the selected lasts a piece of woodis cross cut and tested by timber moisture meter or byoven drying method.

8.4 Mechanical and Other Requirements

Following items shall be tested for mechanical and otherrequirements by cutting or opening up the lasts.

8.4.1 Dimensions qf the Tube

8.4.1.1 Proper jltting of the tube

Measuring the position of the tube vertical to the surfaceof the heel.
