7.2.2.2 The values of yeld and tensile strength also apply to the casting itself up to the maxrnum wall thiclness as given in Table 2.
The yield strength values at room tempeiature correspond 10:
— 0,2 % proof strength (Rg2) for martensitic, austenitic, fuly austenitic and ferrthc-austenibc steels:
— 1.0 % proof strength (Rp1 .o)tor austenitic and fully austenitic steels.

7.4 Corrosion behaviour
Austenilic steel grades shall be resistant to intergranular corrosion when tested according to EN ISO 3651-2.
NOTE All grades of this European Standard have performed satisfactory for long time However it is diffiilt to provide so1ute information on corrosion resistance. Values obtained under laboratory test conditions are not always adequate br the real application. Additives and contamination In the corroalve media can give rise to different results.
Grades may be selected by the pitting index P.1. = % Cr + 3.3 x % Mo + 16 x % N. Based upon this a minimum pitting index can be required by agreement.
8 Testing and documents on material testing
8.1 General
In addition to EN 1559-1:1997:
a) Castings manufactured according to this standard may be supplied with an inspection document according to EN 10204;
b) If. In the case of specific inspection, the issue of an Inspection certificate has been agreed this shall include the following:
1) the amounts of all elements specified (for the cast analysis) for the steel grade required;
2) the results of the mechanical Lest as required for the specific steel grade:
3) a statement on the result of agreed dimensional check and non destructive testing:
4) .. the result of any further mutually agreed testing.
8.2. Inspection and testing
8.3 Test unit sampling
8.3.1 Formation of test units
For castings under 1 000 kg in mass the delivered quantity shall be subciivded into lots covenng castings of the same type from the same rne1t and having undergone the same heat treatment. The mass of a lot (test unit) shall not be greater than 5 000 kg.
8.3.2 For casting more than 1 000 kg In mass, each individual casting shall be regarded as the test unit.
8.4 • Samples (test blocks)
8.5 Test methods
a) • Tensile test at room temperature:
b) tensile test at elevated temperature not applicable;
C) • Impact test;
d) • ferrite content;
e) . herdness test
• homogeneity of test units (hardness test);
g) • pressure or leak testing;
h) .. intergranular corrosion test.
The test, carried out in accordance wth EN ISO 3651-2, shall be agreed at the time of enquiry and order. i) • Tests for magnetic properties.
In addition to EN 1559-2:2000; magnetic permeability shall be specified at the time of enquiry and order.
j) • Other tests for any other properties shall be agreed.
8.6 • Invalidation of tests
8.7 • Retests
8.8 • Sorting and reprocessing
9 • Marking
10 • Packaging and surface protection
