FOREWORD

This Indian Standard ( First Revisian ) was adopted by the Bureau of Indian Standards, after the draft finalized by the Fertilizers Sectional Committee had been approved by the Petroleum, Coal and Related Products Division Council.

Urea ammonium phosphate is the name given to granules made out of urea prills and ammonium. phosphate slurry. The product may contain specific small amounts of inert material to develop adequate physical properties in the granules and to adjust the composition to the nominal grade.

In this revision, in order to align with the specifications of the Fertilizer ( Control ) Order, 1957 and the Essential Commodities Act, 1955 of Government of India, another grade of urea ammonium phosphate ( 20-20-o ) is being included whereas NPK combinations of Grade 19-19-19. Grade 14-28-14 and Grade 17-17-17 are being deleted from this revision. These grades would be covered under IS 7131 : 1973 to be revised to incorporate all NPK fertilizers.

This standard is subject to the provisions imposed under Fertilizer Control Order wherever applicable.

For the purpose of deciding whether a particular requirement of this standard is compiled with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 ‘Rules for rounding off numerical value ( revised )‘. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

METHODS OF TEST FOR UREA AMMONIUM PHOSPHATE BASED FERTILIZERS

A-l DETERMINATION OF RESISTANCE TO BREAKDOWN OF THE GRANULES

A-1.0 General

Two methods are described here. The methods are used to determine comparative hardness of granules and applicable to granulated or pe!leted forms of solid fertilizers. Any of the two methods may be used.

A-l.1 Method A

A-1.1.1 Apparatus

Hardness tester - as shown in Fig. 1.

A-1.1.2 Procedure

Collect a portion of the sample lying in the size range 2’8 mm to 3’35 mm. From the portion obtained pick out at random 25 granules.

Test each granule successively. Place each granule under the ratchet and slowly screw it down until the particle crushes. Note the crush point on the scale indicator and record the load required to crush it.

A-l.1 Calculation

Calculate in kg the mean of the 25 observations and report the results.

FIG 1. HARDNESS

A-1.2 Method B

A-1.2.1 Apparnfus

The apparatus, made of mild steel, is shown in Fig. 2. It consists of two parts, namely a frame and a plunger. The frame is made of three circular plates and three rods fitted with nut and bolt. These rods are fitted vertically on the base plate and the other two plates are fixed tightly in position. Circular holes are made at the czntre in these two plates as shown in Fig. 2 through which the plunger rod can pass through smoothly. The plunger weighing 150 g consists of a circular plate at the top ( for keeping additional weights ) and a narrow stem of diameter 4 mm at the base which can rest either on the base plate or on the fertilizer granule.

A-1.2.2 Procedure

Collect a portion of the sample lying in the size range 2’8 mm to 3’35 mm. From the portion obtained pick out at random 25 granules.

Test each granule successively. Place each granule at the centre of the base plate and keep the stem of the plunger just on its top. Put additional weights on the top of the plunger incremen!ally and note the total weight of the

A-2.1 Procedure

Store one 50-kg packing of the material under

a weight equivalent to twelve 50-kg sample bags of the material for 7 days. Then drop the sampIt: bag from a height of 1’5 meters on to hard concrete floor. Empty out the contents of the bng and determin.: th,: quantity or the material larger than 12 mm size with the help of a standard sieve.

I I Standard Mark

I 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 thereunder. 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 licence for the use of the Standard Mark may be granted to manufacturers or producers may be obtained from the Bureau of Indian Standards.

Review of Indian Standards

Amendments are issued to standards as the need arises on the basis of comments. Standards are also reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision. Users of Indian Standards should ascertain that they are in possession of the latest amendments or edition by referring to the latest issue of ‘BIS Handbook’ and ‘Standards Monthly Additions’.
