6.1 Test categories
6.1.1 To verify that spikes comply with the requirements of this standard, the following tests are performed:
- acceptance tests;
- type tests.
6.1.2 Acceptance of spikes is performed by the manufacturer’s quality control department. Acceptance is based on the results of acceptance tests.
Acceptance tests are performed in accordance with GOST 15.309. Spikes accepted by the manufacturer’s quality control department are presented for acceptance inspection to the customer’s representative upon request.
The results of spike acceptance are kept at the manufacturer for at least three years from the date of manufacture.
6.2 Acceptance tests
6.2.1 Acceptance tests of spikes are performed in lots. A lot shall consist of spikes of one version, made of a single steel grade using a single process, and presented for acceptance under a single document. The lot size shall not exceed 20,000 pcs.
To check the quality of spikes by blind random sampling per GOST 18321-73 (subsection 3.4), the following are sampled from the lot:
- for checking the appearance, surface quality and dimensions of spikes (see 4.2, 5.1.2-5.1.7, 5.2) — 0.1% of each lot, but not less than 10 pcs.;

7.7 For the purposes of mandatory conformity assessment, a sample shall be assembled from a batch that has passed acceptance testing by the “blind” selection method in accordance with GOST 18321-73 (subsection 3.4):
- for checking appearance, surface quality and dimensional inspection of spikes (see 4.2, 5.1.2-5.1.7, 5.2) — 0.1% of each batch, but not less than 5 pcs.;
- for bend and tensile testing (see 5.1.8, 5.1.9) — 4 pcs.
8 Transportation and storage
8.1 Spikes shall be transported by any mode of transport in compliance with the cargo transportation rules applicable to the respective mode of transport, taking into account full utilization of load capacity and the permissible overload in accordance with GOST 26653.
8.2 Spikes may be transported in closed universal metal containers with a nominal mass of 5.0 t in accordance with GOST 15102, closed universal metal containers with a nominal mass of 3.0 t in accordance with GOST 20435, universal containers with a mass of 0.625 and 1.25 t in accordance with GOST 22225, and specialized containers.
