Notes to the table:
1. The MSh-36 and MSh-39 grade mortars may be manufactured with a mass fraction of Fe2O3 of NMT 4% and a relative change in mass on ignition of NMT 5%.
2. By agreement of the parties, it is allowed to manufacture MSh-42 grade mortar with a mass fraction of Fe2O3 of NMT 4% and a refractoriness of NLT 1,710 °С.
3. Mortar of all grades is heat-hardening. MSh-42 grade mortar can be made air-hardening by adding liquid glass at the consumer's.
4. MSh-31, MSh-36, MSh-39 grade mortars may be manufactured with a refractoriness of NLT 1,670 °C, 1,690 °C, 1,710 °C (respectively).
5. By agreement of the parties, it is allowed to manufacture MSh-28, MSh-31, MSh-36, MSh-39, MSh-42, MML-62 mortar grades unplasticised.
6. The MSh-31 and MSh-36 grade mortars may be manufactured with the following grain composition - mass fraction of fractions that passed through mesh number: 2 - NLT 100%, 05 - within (60-94)%.
7. The MKF-95 grade mortar consists of two components and is supplied in the form of dry powder and liquid binder. Mixing of components is performed immediately before use.
