Notes to tables 3 and 3a:
1. The indicators “washing efficiency” and “reduction in sample strength” are assessed only based on the results of acceptance and qualification tests (during the development and launch of products into production). The obtained indicator values ​​are valid throughout the industrial production of the product, unless design and technological changes are made to it that entail changes in these indicators. In the acceptance and qualification test reports, compliance or non-compliance with the standards established by this standard is assessed based on these indicators. The values ​​of these indicators are not indicated in the CG and comparisons with analogues are not made.
2. The actual value of the indicators “washing efficiency” and “reduction in strength” when testing washing machines should not differ from the normalized values ​​of the corresponding indicators given in Tables 3 and 3a by more than the value of the standardized absolute error in the direction of decrease for the indicator of washing efficiency and increase - for the strength reduction indicator.

In this case, the assigned absolute error of the indicator should not exceed in absolute value the standardized error value.

Values ​​of standardized absolute errors:

washing efficiency - 5%;

reduction in strength for activator machines - 3%;

reduction in strength for drum machines - 2%.

APPROVED AND ENTERED INTO EFFECT by Resolution of the USSR State Committee on Standards dated November 23, 1981 No. 5067

STATE STANDARD OF THE USSR UNION

Resolution of the USSR State Committee on Standards dated November 231981. No. 5067, the introduction date has been set

from 01/01/1982

This standard establishes the permissible errors in measuring linear dimensions up to 500 mm during acceptance inspection and the rules for determining acceptance limits taking into account these errors.

This standard does not establish permissible errors in dimensional measurements that are established by others. state standards, and sizes with unspecified maximum deviations.

The standard fully complies with ST SEV 303-76.

1. VALUES OF PERMISSIBLE MEASUREMENT ERRORS

1.1. The permissible measurement errors (δ) depending on the IT tolerances are given in the table.

Note. The permissible measurement errors for tolerances according to the OST system are given in the mandatory Appendix 1.

1.2. The measurement errors established in this standard are the largest permissible measurement errors, including all components that depend on measuring instruments, installation standards, temperature deformations, basing, etc.

1.3. The permissible measurement error includes random and unaccounted systematic measurement errors.

The random measurement error should not exceed 0.6 of the permissible measurement error and is taken equal to 2σ, where σ is the value of the standard deviation of the measurement error.

1.4. For tolerances that do not correspond to the values ​​​​indicated in the table, the permissible error is selected according to the nearest smaller tolerance value for the corresponding size.

2. ACCEPTANCE LIMITS TAKEN INTO ACCOUNT OF PERMISSIBLE MEASUREMENT ERRORS

2.1. The influence of measurement errors on measurement results (see reference appendix 2) must be taken into account when establishing acceptance limits - dimensional values ​​for which acceptance control of products is carried out (see reference appendix 3).

2.2. Acceptance boundaries are set to coincide with the maximum dimensions or are shifted relative to them by introducing a production tolerance (reducing the tolerance).

The first method is preferable.

When introducing a production tolerance, the displacement value should not exceed half of the permissible measurement error established by this standard at each acceptance limit.

2.3. During arbitration rechecking of accepted parts, the measurement error should not exceed 30% of the error allowed during acceptance control. Among the accepted parts, it is allowed to have up to 5% of parts from the rechecked batch with deviations beyond the acceptance limits by a value not exceeding half the permissible measurement error upon acceptance, for qualifications from 2 to 7; series of limits of permissible measurement errors from 1 to 6 (see mandatory appendix 1); up to 4% for qualifications 8, 9 or for rows 7 and 8; 3% - for grades 10 and rougher or for grades 9 and rougher.

LIMITS OF PERMISSIBLE MEASUREMENT ERRORS in microns FOR TOLERANCES ACCORDING TO THE OST SYSTEM

Note. It is allowed to increase the permissible measurement error indicated in the table when reducing the size tolerance, taking into account this increase, as well as in the case of dividing products into size groups for selective assembly.

INFLUENCE OF MEASUREMENT ERROR ON RESULTS OF GRADING DURING ACCEPTANCE CONTROL

1. The influence of measurement error during acceptance inspection is assessed by the following parameters:

m- the number of parts as a percentage of the total number measured, having dimensions beyond the limits and accepted as acceptable (incorrectly accepted);

P- number of parts as a percentage of the total number measured, having dimensions not exceeding the maximum and rejected (incorrectly rejected);

c- the probabilistic value of the size exceeding the limit for incorrectly accepted parts.

2. Parameter values m, P And c when distributing controlled sizes according to the normal law, they are shown in Figures 1 - 3.

3. To hell. 1 - 3 solid lines correspond to the distribution of measurement error according to the normal law, and dotted lines - according to the law of equal probability.

With an unknown distribution law of the measurement error for the parameters m, n And c It is recommended to take the average of the values ​​determined by the solid and dotted lines.

4. Parameters m And c on the graphs are determined with a confidence probability of 0.9973. For determining m with another confidence probability, it is necessary to shift the origin of coordinates along the ordinate axis.

5. Features on the graphs. 1 - 3 values A met (σ) in coordinates is determined by the formula

where σ is the average standard deviation measurement errors;

IT - tolerance for controlled size.

When defining parameters m, n And c recommended to take A met (σ), equal to 16% for qualifications 2 - 7, 12% - for qualifications 8 and 9 and 10% - for qualifications 10 and rougher.

6. Parameters m, n And c are shown on the graphs depending on the value, where σ tech is the standard deviation of the manufacturing error.

7. Parameters m, n And c to hell 1 - 3 are given for a symmetrical location of the tolerance relative to the center of grouping of the controlled parts.

8. Combined influence of systematic and random manufacturing errors on parameters m And n determined by trait graphs. 1 - 2, but instead of the value taken for one border

From 0.37 to 0.39

From 0.7 to 0.75

Notes:

1. First values m And n correspond to the distribution of measurement errors according to the normal law; the second - according to the law of equal probability.

2. Limit values ​​of parameters m, n and , - take into account the influence of only the random component of the measurement error.

APPENDIX 3

Information

ACCEPTANCE LIMITS TAKEN INTO ACCOUNT OF MEASUREMENT ERROR

This standard provides two methods for establishing acceptance limits

1st method. Acceptance boundaries are set to coincide with the maximum dimensions.

Example. When designing a shaft with a diameter of 100 mm, it was estimated that the deviations in its dimensions for operating conditions should correspond to h6 (100 - 0.022).

In accordance with the table of this standard, it is established that for this shaft size and tolerance the permissible measurement error is 0.006 mm.

In accordance with the table in reference appendix 2, it is established that for A met (σ) equal to 16%, and unknown accuracy technological process m= 5.2 and c= 0.25 IT, i.e. Among the acceptable parts there may be up to 5.2% of incorrectly accepted parts with maximum deviations of +0.0055 and -0.0275 mm. If the data obtained does not affect the performance of the shaft, then the initially selected quality is indicated on the drawings. Otherwise, choose a more precise quality or another tolerance field in this quality.

2nd method. Acceptance boundaries are shifted inward relative to the maximum dimensions.

When introducing a manufacturing tolerance, there are two options depending on whether the accuracy of the process is known or unknown.

Option 1. When assigning limit sizes, the accuracy of the technological process is unknown. In accordance with clause 2.2 of this standard, the maximum dimensions are changed by half the permissible measurement error. For the example discussed above, the diameter
