Original version in: English

1 Introduction

1.1 This Report Format applies to any kind of load cell (independent of its technology). It presents a 

standardized format for the results of the various tests and examinations, described in Part 2 of R 

60 (20XX), to which a type of load cell shall be submitted for the purpose of its approval based on 

this OIML Recommendation.

1.2 It is recommended that all metrology services or laboratories evaluating and/or testing types of load 

cells according to OIML R 60-1 20XX, or to national or regional regulations based on that 

Recommendation, use this Report Format, directly or after translation into a language other than 

English or French. In case of a translation, it is highly recommended to leave the structure and the 

numbers of the clauses unchanged: in this case, most of the content is also understandable for those 

who can not read the language of the translation.

1.3 Some of the tests may have to be repeated several times and reported using several identical sheets; 

therefore, report pages must be numbered in the space provided at the top of each page, completed 

by the indication of the total number of pages. 

1.4 In the practical application of the Report Format, in addition to a cover page by the Issuing 

Authority, as a minimum, clauses A–F (as necessary) shall be included

1. Applicability of this Report Format 

In the framework of the OIML Certificate System for Measuring Instruments, and the OIML Mutual 

Acceptance Arrangement (MAA) applicable to load cells in conformity with OIML R 60-1 20XX Parts 1 

& 2, use of this report format is mandatory, in French and/or in English with translation into the national 

languages of the countries issuing such certificates, if appropriate. 

Implementation of this Report Format is informative with regard to the implementation of OIML 

Recommendation R 60 parts 1 & 20XX in national regulations.

1.1. Calculation procedures

1.1.1. In order to facilitate a comparison of the reports established in English and in French, the 

same abbreviations (those of the English language) are used in both versions; the 

meanings of these abbreviations is given whenever appropriate. 

In testing and evaluating load cells for pattern evaluation, it is recognized that the test 

apparatus and practices used by the various laboratories will be different. OIML R 60 

allows for these variations and still provides a method for testing, recording and 

calculating results that are readily understandable by other knowledgeable parties 

reviewing the data. 

In order to achieve this ease of comparability it is necessary that those persons conducting 

the tests use a common system for recording data and calculating results. 

Thus, it is essential that the calculation procedures below be reviewed and followed 

closely in the completion of this test report. 

1.1.2. Load cell errors (EL = Error Load test)

1.1.2.1. Complete a Table 6.3 for each test temperature, calculate the averages and

record in the right hand column. When five runs are necessary, use Table 6.4. 

1.1.2.2. Determine the conversion factor, f, which is the number of indicated units per 

load cell verification interval, v, and is used to convert all “indicated units” to 

“v”. It is determined from the test data averages of the increasing load tests at 

the initial 20 °C nominal test temperature. 

1.1.2.3. If a test load corresponding to 75% of the measuring range for the load cell 

under test (i.e., 2 250 divisions for a 3 000 division cell, which is Dmin plus 75 

% of the difference between Dmax and Dmin) is not included in the test loads 
October 2016 OIML R 60-3

4

used in Table 4.10.1, interpolate between the adjacent upper and lower values 

of the averages of all three test runs and record in Table 4.10.3 (see R60-1: 

8.8.2). 

1.1.2.4. Calculate the difference between the average indication on the increasing load 

test runs at 75 % of the difference between Dmax and Dmin and the indication at

Dmin. Divide the result (to five significant figures) by the number of 

verification intervals (75% of n) for that load to obtain the conversion factor, f,

and record in the tables that follow. 

f = average indication at [Dmin + 0.75 ∙ (Dmax − Dmin )]

0.75 ∙ n

The units of conversion factor f are indicated units (e.g. digits or counts) per load cell 

verification interval v.

1.1.2.5. Enter the average test indications of the tests at the temperatures following the 

initial test at a nominal 20 °C in Table 6.5. In recording this data, indicate a 

“no test load” indication (at Dmin) as “0”. This may require subtracting the “no 

load indication at Dmin” from the “test load indication” so that the first entry in 

the column is “0”. These “0’s” have been preprinted on the form to clarify that 

a dead load condition is recorded as “0”. 

1.1.2.6. Calculate the reference indication, Ri, by converting the net test load, in mass 

units, to indicated units (e.g., counts or digits), by multiplying by the 

conversion factor, f, for each test load and recording in the 2nd column in 

Table 6.5.

Ri = (test load i - Dmin)

(Dmax − Dmin) ∙ n ∙ f

1.1.2.7. In Table 6.5 calculate the difference between the average test indication and 

the reference indication for each test load at each test temperature and divide 

the result by the conversion factor f to obtain the error, EL, for each test load in 

terms of v. 

EL = (average test indication for test load i – reference indication Ri) / f

1.1.2.8. Compare EL with the corresponding MPE for each test load.

1.1.3. Repeatability error (ER in terms of verification interval v)

1.1.3.1. Enter data in Table 6.6. 
OIML R 60-3 October 2016

5

1.1.3.2. Calculate the maximum difference between the indications of the on Form 6.3

and divide it by f to obtain the repeatability error, ER, in terms of the load cell 

verification interval v. 

ER = (maximum indication of the test load – minimum indication) / f

1.1.3.3. Compare ER with the absolute value of the corresponding MPE for each test 

load. 

1.1.4. Temperature effects on minimum dead load output (MDLO) (CM = Change MDLO) 

1.1.4.1. Enter in Table 6.7 the average indication for the initial minimum test load, 

Dmin, for each test temperature from Table 6.3. 

1.1.4.2. Calculate the difference between the average test indications for each 

temperature Ti in sequence and divide the result by the conversion factor f to

obtain the change in terms of the load cell verification interval v. 

CM = (average test indication at T2 – average indication at T1) / f

1.1.4.3. Divide CM by (T2 – T1) and multiply the result by 5 for class B, C, and D load 

cells or 2 for class A load cells. This gives the change in v per 5 °C for class 

B, C, and D load cells or in v per 2 °C for class A load cells. 

1.1.4.4. Multiply the result by [(Dmax – Dmin) / n] / vmin to give the final result CM(vmin) 

in units of vmin per 5°C for class B, C, and D load cells, or in units of Vmin per 

2°C for class A load cells. CM(vmin) must not exceed pLC. 

CM(vmin) = CM ∙ (Dmax − Dmin)

nn ∙ vmin

pLC ≤ CM(vmin)

1.1.5. Creep magnitude CC(t) and minimum dead load output return (CDR) 

(CC(t) = Creep, expressed in terms of the load cell verification interval, v)

(CDR = DR, expressed in terms of the load cell verification interval, v) 

Remark: Contrary to the minimum dead load output return DR in terms of mass the minimum 

dead load output CDR is expressed in terms of the verification interval v).

From the test indications recorded in Table 6.8, calculate the difference between the 

initial indication obtained at the minimum creep test load after the stabilization period 

and any indication obtained over the 30 minute test period with the maximum creep test 

load of 90% to 100% of Emax and divide by the conversion factor the conversion factor f.

CC = (indication – initial indication) / f
October 2016 OIML R 60-3

6

Remark: If the minimum creep test load or the maximum creep test load differ from Dmin or 

Dmax according to 2.1.2 ”Load cell errors EL” the conversion factor f must be 

recalculated with the minimum and maximum creep test loads (see 2.1.2.4).

1.1.5.1. CC (t) must not exceed 0.7 times the absolute value of the MPE for the

maximum creep test load at any time t over the 30 minute creep test period. 

1.1.5.2. Calculate the difference between the test indications obtained at t = 20 minutes 

and t = 30 minutes after the initial indication at t = t0 and divide by f to obtain 

the creep error, CC (30 – 20), in terms of the load cell verification interval v. 

CC (30 – 20) = (indication at time t = 30 minutes – indication at time t = 20 minutes) / f

1.1.5.3. CC (30 – 20) shall not exceed 0.15 times the absolute value of the MPE for the 

applied load. 

1.1.5.4. Calculate the difference between the initial indication obtained at the minimum 

creep test load after the stabilization period (t 0 = 0 min) and the indication at 

the minimum creep test load after the creep test and after a time interval for 

stabilization (t > 30 min) and divide the result by conversion factor f to obtain 

the minimum dead load output return, CDR, in terms of v. 

CDR = (indication at the minimum creep test load indication – initial indication at the minimum creep

test load indication) / f

1.1.5.5. If the time intervals specified in R60-1: Table 7 have been met, CDR must not 

exceed 0.5 v. 

1.1.5.6. If the actual time is between 100 % and 150 % of the specified time in R60-1: 

Table 7, then the following applies:

CDR ≤ 0.5 (1 – (x – 1))

with

x = actual time/specified time

1.1.5.7. Whereas CDR expresses the minimum dead load output return in terms of v, the 

value of DR as used in the OIML R76 is expressed in units of mass (g, kg or t). 

1.1.5.8. Calculate the minimum dead load output return, DR, expressed in units of 

mass (g, kg or t) as follows: DR = (Emax – Emin × CDR) / nmax nLC

1.1.5.9. Regardless of the value declared by the manufacturer for the apportionment 

factor, pLC, the MPE for creep shall be determined from R60-1: Table 4 using 

the apportionment factor, pLC = 0.7 (see R60-1: 5.5.1). 
OIML R 60-3 October 2016

1.1.6. Barometric pressure effects1 (CP = Change Due to Barometric Pressure) 

1.1.6.1. From the test indications recorded in Table 6.9, calculate the difference 

between the indications for each pressure and divide the result by conversion 

factor f to obtain the change, CP, in terms of v. 

CP = (indication at P2 – indication at P1) / f

1.1.6.2. Divide CP by (P2 – P1) to determine the change due to barometric pressure in 

terms in terms of v per kilopascal (kPa). 

1.1.6.3. Multiply the result by [(Emax– Emin) / nmaxnLC] to obtain the result in units of mass (g, 

kg, or t) per kPa (as stated by the manufacturer). The result must not exceed vmin.

CP(vmin) = CP

(P2−P1) ∙

(Emax−Emin)

nmax

≤ vmin

1.1.7. Humidity effects2 (CH or no mark) 

(CHmin= Change in terms of v due to Humidity effects on the indication 

of the minimum test load Dmin)

(CHmax= Change due to Humidity effect on the indication of the maximum test load Dmax)

Remark: If the minimum or maximum test load used for this test differ from the minimum test 

load Dmin or maximum test load Dmax according to 2.1.2 ”Load cell errors EL” the 

conversion factor f must be recalculated with the minimum and maximum test loads 

of this test (see 2.1.2.4).

1.1.7.1. From the test indications recorded in Table 6.10.1, calculate the difference 

between the initial indications for the minimum test load, Dmin, before and after 

the damp heat test and divide the result by conversion factor f to obtain the change,

CHmin, in terms of verification interval v (see R60-1: 5.6.3.1).

CHmin must not exceed 0.04 ⋅ n.

1.1.7.2. Calculate the average indications II{̅Dmax} and II{̅Dmin} at Dmin and Dmax (see R60-1: 

8.10.5) for the required number of test indications, before and after the damp heat test. 

Subtract I̅{Dmax} from II{̅Dmin} for the tests before and after damp heat test and then 

calculate the difference between the results. Divide the result by the conversion factor 

f to obtain the change, CHmax, in terms of v.

CHmax = [(II{̅Dmax} − II{̅Dmin} )after – (II{̅Dmax} − II{̅Dmin} )before]

ff

1.1.7.3. CHmax must not exceed the MPE (see table 4 in 5.3.1.1).

 1 This test may not be necessary depending on the design of the load cell.
