GB/T 4513.5-2017Monolithic (unshaped) refractory products -- Part 5: Preparation and treatment of test pieces (English PDF)

1 Scope

This section GB/T 4513 specifies the size of amorphous refractory sample, describes the preparation and pretreatment of the sample (curing, drying

And heat treatment) method.

This section applies to dense castable, insulation castable, refractory ramming material, refractory plastic and dry material.

3 sample size

The sample size has the following types .A-shaped .230mm × 114mm × 64mm; B-shaped .230mm × 64mm × 54mm;

C-shaped 230mm × 64mm × 64mm; D-shaped. 160mm × 40mm × 40mm.

The width of the sample preparation as the test height, deviations should be recorded, C, D-shaped specimen molding surface should be marked. In addition to ramming

Materials and dry materials, the sand can be used to prepare hammer hammer 50mm diameter and height of 50mm ± 1mm of the sample, a variety of materials, sample size

Select Table 1. C-shaped laboratory arbitration sample size. The size of the sample chosen by the parties concerned to determine.
